The touchscreen does not work on Xiaomi what to do?

As a result of a fall from a height, a manufacturing defect or other unforeseen circumstances, the touch screen of a smartphone may fail and it will be almost impossible to control the mobile device. What to do if the touchscreen does not work on Xiaomi?

Naturally, the most correct decision is to take the phone to a service center for repair, but this pleasure will not be cheap, since on modern smartphones the touchscreen changes along with the display.

In the event that smartphone repair can be postponed, but you still need to use the device during this period, use some useful tips.

Mouse connection via OTG

OTG technology allows, using a special adapter, to connect not only flash drives, but also mice, as well as any other devices.

After connecting a wired or radio mouse via OTG, a cursor will appear on the smartphone display, with which you can fully control the mobile device in the same way as on a regular PC. This method will allow you to prepare a smartphone before sending it to a service center, as you can remove all unnecessary information that should not be seen by the masters.

Connecting a mouse or joystick via Bluetooth

This method is more convenient, since you do not have to constantly keep the wire in the phone, while you have a USB port that can be used to charge your smartphone or connect to a PC. The disadvantage is that the mouse (joystick) must be paired before the touchscreen breaks or the mouse needs to be initially connected via an OTG cable and the bluetooth device will be configured using it.

For more information about wirelessly connecting devices to a smartphone, see the article:

One-hand control mode

In the event that only the upper or left part of the touch screen does not work on the smartphone, you can try turning on the one-handed control mode. This mode reduces the working area of ​​the display, and therefore allows you to minimize the area of ​​damage to the touchscreen.

Headset and automatic call answering

Despite the inconvenience that damage to the touch screen will bring, you can at least receive phone calls. To do this, you can connect a wired (or wireless) headset or turn on automatic answer for an incoming call.

In any case, damage to the touchscreen makes the smartphone less functional, and therefore sooner or later it will have to be repaired or replaced.

Common repair options

These steps will help in many cases of Android phone or tablet malfunctioning due to software, so you can apply these tips when in doubt about the correct operation of the system.

  • Reboot your device. It may have been under heavy program load or a minor bug has occurred. Maybe the application just hung, but the sensor works?
  • Update firmware. To do this, go to the following items: Settings. About device. System updates. Check now. Most often, the problem is solved.
  • Reset the settings to factory settings. Save all important data to a memory card, computer or similar media. Click Settings. Memory. Factory Reset. Factory Reset. Erase Everything. Confirm your choice if necessary. Wait a few minutes and the reboot will automatically
  • What to do if the screen is buggy? If it works, but slowly, just clean the phone as a whole. Delete unnecessary files and applications and cache (Settings. Applications. any application from the list. Clear cache). Use CCleaner, Cleaner Master or another application to remove other junk and clean up RAM.
  • Determining the state of the buttons. In order to understand how serious the problem you are facing, you need to determine whether the bottom buttons respond to touch. To do this, you need to enable a feature called Vibro confirmation. To activate it, go to the Sound Settings menu, and at the very bottom of the list that appears, check the box next to the Vibrate confirmation function.

Now your smartphone should vibrate every time you press the bottom buttons. If this happens, proceed to the next step. If not, try steps 3, 4 or 5 of this guide.

Select Advanced Settings Calibration Tool. After that, a sentence will appear on the screen, which must be typed on the keyboard. Follow the green circle.

If you can’t calibrate your keyboard, or you’re doing it wrong, go to HTC Sense Input Advanced settings Reset calibration. This will reset the screen calibration to factory settings. Then you can calibrate again.

  • Software Update. Perhaps the problem with non-working buttons lies in the outdated software of your smartphone. Update the software, this method often helps.
  • Software reset to factory settings. After saving all the data from the internal memory of the smartphone to removable media, reset the device to factory settings. We recommend resetting only for those users who could not fix the problem in the two previous methods. To reset the settings, go to the menu Settings Memory Reset to factory settings.

Then a menu will appear in which we select Reset phone settings Erase everything.

  • Hard reset to factory settings (this method will be useful for those users who do not have touch buttons and have similar problems with the touch screen). First, save all personal data from your phone to removable media. Now press and hold the volume down button. Without releasing it, press and hold the power button. Release both buttons when the splash screen appears. The menu that appears is controlled by the volume up and down buttons. By pressing the volume down button, select Restore the original settings (Eng. Factory Reset). To confirm your choice of action, press the Power key.

If these methods did not help you, make sure that you followed all the steps correctly and consistently, try to do each step again. Also remember that often the failure of the bottom buttons of HTC smartphones is due to a faulty display module or hardware problems of the device.

Based on the requests, a very large number of users are faced with various kinds of problems with the sensor. And the non-working bottom buttons are quite often their manifestation. The problem did not bypass the author of this project. I propose a solution to this problem (software).

After reading a number of forums, I realized that the problem is one, and the causes and solutions may be different.

To begin with, I will say that information was found at the expense of physical repairs. According to the author, you need to take a binder clip (two or more) and press the smartphone screen from below. Heat strongly with a hairdryer and leave for 12 hours. Many devices have been repaired in this way. But. this method works if the problem is peeling off the sensor components inside.

I offer software solutions that can be used temporarily (before repair) or on a permanent basis. Phone example Lenovo K6.

For starters, you can reset the settings to factory settings using the menu (if the sensor or the phone in general is working). In different phone models, this function can be called in different ways. Be sure to make a backup before resetting, since all information from the device’s memory will be erased (the data will remain on the memory card, but I, for example, would have pulled it out at the time of the operation). Here is an example for a Lenovo K6 phone (should work for most).

Home Button/Back Button Not Working|| Fix problem Easy step||Xiaomi Redmi (Mi) Fix Capacitive Button

Go to settings (gear icon) and find the option Backup and reset → Reset settings → Reset settings.

We confirm our actions. The phone will reboot and erase all data. The operation may be delayed. Do not press any buttons until the process is over and make sure that the battery is enough, if not, connect the smartphone to the charger.

After completion, you will need to re-log into accounts, install applications, and so on. If the sensor worked, then the problem was in the software. This procedure has helped many people. Otherwise, read on.

If you cannot enter the menu, you can use the hardware keys. First you need to turn off the device. If it freezes, press and hold the power button until the phone turns off. To enter the system menu, you need to press in most cases two keys. For each model, the combination of these keys may be different. For my model, these are the volume and off keys. Search in detail for your model (or ask in the Комментарии и мнения владельцев). If everything is done correctly, the Recovery menu will appear. Touch capabilities may be limited, so use the volume keys to switch menu items. To confirm the current item, press the power key once. To reset the settings, you need to look for the item Wipe data / factory reset or similar (I have Wipe user data). You will be prompted to confirm the deletion, which must be confirmed by pressing the power key. After the reset is completed, you need to reboot the device (Reboot System). You will receive a clean phone as at the time of purchase.

Reset using keyboard shortcuts. In the Phone app, enter one of the codes you see below and press (if necessary) the volume key:

After the reboot, the reset process will begin.

The second way is to install a special program that will take over the functions of all three buttons and will be placed at the bottom of the screen.

There are many such programs. This indicates the prevalence of the problem. I will tell and show everything using the Simple Control program (Navigation bar) as an example. It has a free (with ads) and a paid version, works without root and does its job perfectly. If this program does not work for you, you can easily find an analogue in the market. There is a Russified version on the Internet.

First you need to install this program. Next, open and perform the initial settings through which the pre-installed wizard will guide you. Nothing complicated. just give the program a few permissions so that it can work. Keep in mind that after rebooting the device, permissions may need to be granted again.

You can customize the appearance of the buttons, their size (handy, especially if you have a small screen) and the execution of functions. For example, it is possible that when you press the Back button, it performs the function of returning to the previous menu, and when you double-click it, you exit the program. Is it possible to press the button to return home or turn it off altogether.

Please note that short and long presses of each of the three buttons are separately configured.

Animation is also configured, you can configure auto-hide. There is a floating activator output function. Simple Control works great and performs all the functions assigned to it.

If we talk about possible reasons why the touch buttons on an Android phone stopped working, the failure is more often on the physical side than on the software side. If there are reasons from the first list, you will most likely have to carry the device to a service center.

  • A strong blow to a tablet or smartphone, a fall from a height.
  • Prolonged exposure to moisture. Particularly serious damage occurs due to water entering the area between the screen and the film or under the case. Contacts are oxidized. After exposure to moisture, you need to act immediately.
  • Sharp temperature changes. Return the device to a room at room temperature. Sensor performance may improve.
  • Screen punching. There are no scratches or cracks. Breakage is noticeable when pressed. then glare is visible in the damaged parts of the sensor.
  • Replacing the screen with the wrong model.
  • Serious pollution. Wipe off dirt, dust, moisture, fingerprints with special wet wipes from an electronics store or a microfiber cloth.
  • Bad film. In places where air accumulates under the film, parts of the screen will stop working. Remove the film, if possible, replace with a new one.
  • The OS is overloaded with applications or some of them do not work properly.
  • Change device settings.
  • Touchscreen problems are possible if the screen does not recognize touch correctly or poorly. Screen calibration will help here (really do it at home).
  • Inappropriate or unstable firmware version.

Why doesn’t the sensor part work on Android? Most likely, the contact has departed or oxidized.

How to restart Android if the sensor is not working

On a phone with a removable battery, remove the cover and remove the battery. Insert it back and turn on the device using the mechanical button. If the sensor does not work partially, but not completely, and you can download the application, install Rebooter from the Play Market. On Xiaomi, Meizu or Digma, after long pressing the on/off button (20 seconds or longer), the phone will restart or turn off. For Samsung and Sony, press the Power/Lock, Volume Up, and Volume Down buttons at the same time. Hold for 7-10 seconds. If it doesn’t help, try again, but keep these three keys pressed for longer. If your smartphone is from other manufacturers and has a built-in battery, the above methods may help. Otherwise, you will have to wait for the battery to completely discharge or carry the device to a service center, where at the same time they will deal with problems with the screen. It also happens that a reboot is needed only for the display to respond again. What to do if the touch on Android does not work after locking the screen?

Most often the problem is in the firmware version. To solve it, update the version of Android and, if it does not help, reset the settings. How to do this is in paragraphs 2 and 4 of the instructions of the next paragraph of the article. Why are the touch buttons not working on an Android phone? Sometimes the film is the problem. If everything was fine before it, try to remove it. Sometimes it’s even a new protective glass, which can also be detached on its own. Users say that the bottom touch buttons, which stopped working after calibrating the screen (3rd step of the next instruction), became sensitive again.

How to fix the device

It is unlikely that you can fix the phone yourself. You will succeed when the cause of the fault is in the software. In this case, read the methods below.

If you have any questions let us know Ask a question

  • Calibrate the screen. Depending on the manufacturer, there may be a built-in utility for this, or you will have to download the application yourself. There are several ways. For HTC models: Settings. Language and keyboard. HTC Sense Input. On other smartphones: Settings. Display. Screen. Screen calibration. Optionally, you can calibrate the screen through the engineering menu. It is used by developers to test and modify system components. We do not recommend this method as it can cause problems and take longer than other methods. A third-party screen calibration app from the Play Market will be able to improve the display’s response. For example, Touchscreen Calibration or SGS Touchscreen Booster (it can be set manually).
  • The bottom touch buttons do not work on an Android phone, what should I do? You can install an application to create soft buttons with the same functions, but in a different location. We recommend Back Button. it does not require root rights.

Contact the service center. They will more accurately determine the cause and repair the device.

Oxides can lead to current leakage, and this contributes to the heating of the device. To fix, you need to clean the USB. Take a thin stick and wrap cotton wool around it. Dip it in white spirit or alcohol, and wipe the contacts at the entrance.

If water got inside, then you need to disassemble Meizu. And, carry out the same operation with contacts that are attached to the board. But, before doing this, disconnect the battery cable to avoid a short circuit.

Also, software methods can be used. But, they can only help if there are no malfunctions in the device itself. This method is one of the simplest, we open the settings on the mobile phone. And, select the command “reset settings”. Keep in mind that this means deleting all data from the smartphone.

So that the stripes on the Meizu M8 screen do not bother you, you need to:

  • Make sure the integrity and reconnect the display module cable;
  • Replace the screen completely if there is real damage;
  • Update firmware and Flyme shell.

  • Enter the device settings;
  • Select “About phone”
  • In the submenu, you will need to select check for updates. when you turn on Wi-Fi, everything will start downloading;
  • The device will reboot.

A banal method is to simply log into your account on the device. Click on the item “Delete Mi account” below.

In this case, the account will be unlinked from the mobile phone. There will no longer be a message when the machine is booting up.

If Xiaomi has lost sound, you should first check the audio settings. If there is an active mode (with sound), then we continue to look for the problem.

Necessary. clean the headphone jack.

If the headset icon is on the screen of the Xiaomi smartphone, and the headphones are not connected, it means that the contacts are shorted. Therefore, the sound is transmitted to the headphones, even though they are not physically connected.

Reboot your phone after cleaning.

How to talk to Xiaomi technical support.

Go to your mail service type and log in.

Click create message. In the first line, we write this address: Or this one: You can write in the subject (Unlock mi account). You must write in English. Use an online translator.

Next, we write what is required. I want to reset my Mi account on Xiaomi Redmi 6a. This procedure is long and may take 2-3 weeks.

Choose English and any country;

We make an Internet connection using Wi-Fi or cellular data;

We go to ” Privacy Policy” (Security Policy) and select any piece of text. On the right, click on the three dots, “Web Search” and “Google App”. Next, we can go to the settings by clicking on the “Settings” entry. We are looking for the item “About Phone” and click on it.

After logging in, click on “Software version (Miui version)”, which you need to quickly click a few (about 5) times until a notification appears about granting “Developer rights”. We go back and go to “Second Space”, and then “Turn on second space”.

Here a second space is created and the device is already quite ready for work. Nevertheless, after the reboot, everything will be reset and you will have to do everything again, so we continue. We go into the settings, then “About Phone”, “Additional Settings” and “Developer Menu (Developer)”. Move switch USB Debugging to the enable position.

We connect to the computer using USB and start Switch. Download “Minimal Adb and Fastboot” and turn it on. We go to the first desktop, and on the computer we type “adb devices”.

Nuances after such a decoupling.

After that, the gadget is ready for full operation: you can go online, use various programs, etc.

Fn and function keys F1÷F12 do not work on a laptop

Good day!

Oh, these modern keyboards, with which manufacturers are doing everything now. And the problem with the performance of the keys even of a new device is not uncommon. #x1f440;

Actually, today’s article will be about the operation and configuration of the F1÷F12 and Fn function keys on laptops. The fact is that often they either do not work at all, or do not work as they should.

over, many manufacturers “fence” the shape of the keys, their functions, on / off, setting as they please (no standardization).

Meanwhile, the keys Fn, F1, F2, F3, etc. are very important, they allow you to quickly add / decrease brightness and sound, turn on / off the Wi-Fi network, touchpad and much more.

In general, to refuse them means to deprive yourself of the necessary functionality, which is not good.

Causes of inoperability of Fn and F1÷F12

I remind you. that in most cases, in order for the function keys to perform an alternative function (reduce the same brightness), you must press them simultaneously with the Fn key.

For example, in order to turn Wi-Fi on / off, you need to press the FnF2 combination (this is an example! Each laptop has its own combinations, see carefully the pictures on the keys).

Simultaneously pressing FnF2. turn Wi-Fi on or off / as an example!

1) Is Fn enabled? Is there an alternative button on the keyboard?

Some types of keyboards have additional F Lock or F Mode buttons. They allow you to block (disable) the function keys. Take a closer look. do you have them?

F Lock key (most commonly found on classic keyboards, not laptops)

I also note that in order to use the Fn button, on some laptops you need to press the FnEsc button combination (see the screen below. a small lock should be drawn on the key). By the way, instead of FnEsc, a combination of FnNumLock can be used.

2) BIOS settings (Hotkey Modes and analogues)

#x1f449; remark!

If you do not know what BIOS is and how to enter it, I recommend that you read this note.

In some laptops (for example, Dell Inspiron, Lenovo ThinkPad, etc.), you can set the operating mode of the function keys in the BIOS (i.e., they can play a classic role, or they can immediately perform their second function without pressing Fn: turn down the sound. enable/disable the touchpad, etc.).

Most often, to enter the BIOS, you need to restart the laptop, and when it is turned on (before Windows loads), immediately press the F2 or Delete keys (the buttons may be different, depending on the device model).

Such modes are called: Hotkey Mode, Action Keys Mode (and other derivatives). To change their mode of operation, you need to go to the BIOS Configuration section and change the mode from Enabled to Disabled (or vice versa).

hot key mode. modified mode of the keys F1-F12

3) Lack of drivers and special software from the manufacturer

When drivers are automatically installed along with Windows, or various kits / packs are used (for example, Driver Pack Solution), the system often does not have special software from the laptop manufacturer. As a result, some keys may not work (including function keys).

I will consider below an example of updating such drivers using Asus as an example (if your laptop brand is excellent, say HP, Acer, Dell, Lenovo. all actions will be similar, only the address of the official site will be different).

  • Go to the official website:
  • Enter your laptop model and click the search button (as a help: how to find out the laptop model);

In general, to summarize: you just need to update the drivers by downloading them from the website of your laptop manufacturer. over, you need to do this for the specific version of Windows that you are currently using.

If there are no drivers for your version of Windows on the website of the laptop manufacturer, then this is a serious reason to think about switching to another version of the OS (it is quite possible that some of the functionality, including the function keys, does not work because of this).

#x1f449; Addition!

Perhaps someone will need an article on how to install drivers on a laptop or PC (various options are considered).

4) The problem with the keyboard itself

If you dropped or #x1f449; flooded the laptop with liquid. it is quite possible that the key does not work due to a physical malfunction of the keyboard.

Pay attention to whether the key reacts at least sometimes (maybe try pressing it a little harder). If there is a problem with the tracks under the key, then often a stronger pressing works (for example, the tracks may oxidize after flooding, or behave like this due to wear).

  • replace the keyboard on the laptop with a new one (I recommend taking it to the service for diagnostics, because it will not be superfluous to check if there are any problems with something else);
  • connect an external keyboard to the USB port and use it (isn’t it a temporary option?); to another;
  • use the on-screen keyboard. To access it, go to: Control Panel\Ease of Access\Ease of Access Center

Volume buttons do not work on Xiaomi Troubleshooting

Xiaomi brand smartphones are famous for their operational stability. But even very reliable mobile equipment sometimes fails. The weak point of phones is the mechanics. the volume and power buttons. With the active use of the gadget, it is the “physical elements” that are the first to fail. Their performance can be easily restored by the specialists of the service center. But before contacting them, you should try to return the functionality of the volume button to Xiaomi yourself. In 8 out of 10 cases, the problem with adjusting the sound power is solved elementarily.

Xiaomi volume buttons not working

Causes of breakdown

The most obvious and common reason is the physical wear of mechanical elements. Even very careful handling of equipment in 1.5-2.5 years will lead to discomfort in the operation of mechanics. In this case, the only solution is to have the mechanical unit replaced at a service center. The procedure takes a minimum of time, the service is inexpensive. They are independent of the screen, so the replacement will not degrade the experience with a mobile device.

The reasons why the volume buttons break on Xiaomi:

  • aggressive use of the phone;
  • damage to the cable (often due to falls, kinks in the case);
  • landing site pollution;
  • system and software failures.

Knowing the cause of the failure, it is easier to find the correct solution to restore the smartphone’s performance. Shocks, ingress of moisture, dust, dirt and careless pressing reduce the life of mechanical elements by 3 times.

Symptoms of a non-working volume button on Xiaomi

If a problem is detected in a timely manner, it will require a less time-consuming, costly solution. With active listening to music, watching movies or cartoons on the phone, experts recommend “listening” to the features of the device. The following symptoms should be alert:

  • reduced degree of “responsiveness” to the user’s action;
  • sinking;
  • the appearance of a crunch;
  • the need to apply force when pressed;
  • triggering action after repeated pressing.

Often a problem with the mechanics appears after the next download and installation of updates. It is worth remembering when the last time a new version of the software was installed.

How to restore the volume button on Xiaomi?

The first thing to do when identifying a problem is to turn off and on the smartphone. In 35% of cases, the cause of the failure is software, not physical. After turning off, wait 30 seconds-1 minute, turn on the gadget. This often happens after repeated installation and removal of applications, launching “heavy” games, watching videos for a long time. When the system is heavily loaded, freezes, incorrect operation of applications, and functional failures in the operation of the mobile device may occur. Problems with the mechanics can also arise after the next update of the Android operating system.

Landing pad cleaning

Carrying a phone in a or bag often leads to foreign bodies getting inside the case. In this case, pressing the button is difficult. She doesn’t seem to be under pressure. Do not use force. It is recommended to perform a gentle 10-fold pressure without effort. Physical actions will move the barrier, eliminate discomfort. If a foreign object is visually visible between the button and the housing wall, tissue paper should be used to remove it. It is wiser not to extract with a toothpick, paper clip or other hard object.

If pressing difficulties occur frequently, it’s time to clean the block’s landing pads. It is better to entrust this to the specialists of the service center, since the procedure will require parsing the case. The complexity of the work depends on the model of the Xiaomi phone.

Using System Features

Using gadget functions is a temporary solution. Until the functionality of the volume button on Xiaomi is restored, it is easier to use the internal settings. Actions:

It will be less convenient to work with the Accessibility menu. They are located in the “Settings” of the smartphone at the bottom of the list. On the panel to adjust the sound power, select the item “Volume”.

Third party software products

From the Google Play Store, you can download a special application for free to adjust the volume or move the buttons on the screen. There are a lot of software products, in order to choose the best one, you need to read user reviews and software functionality. It is wiser to choose the application with the largest number of downloads, small volume (do not load memory).

  • In the search bar of the Google Play Store, enter “volume control”.
  • Select application.
  • Click on the “Download” button.
  • Wait for installation.
  • Reboot device.

After installation, the software product will allow you to adjust the sound from the touch screen.

Alternative ways to solve the problem

If the listed methods to restore the functionality of the mechanical elements did not work, you can perform a factory reset. This is an extreme method, using which you must not forget to back up your gadget data. The reset procedure is performed through the “Settings”. Here you need to find the “System” item, select “Return to factory settings” from the list. The Xiaomi brand has provided an engineering menu for testing the operation of the mechanics. But in 79% of cases, its use is effective only with physical wear and tear. Therefore, if the problem persists, it is better to seek professional help.

Комментарии и мнения владельцев

None of the methods helped, but thanks for the tip on applications. Installed on Xiaomi Mi 9 a program to amplify the sound This is something.

I had to carry my xaomi in for repair. I climbed to pull out the dirt with a needle and broke it completely

Thanks for the detailed review. Very informative. True, I have never had problems with Xiaomi phones, but for general development it is interesting to read.

Why the touch navigation buttons stopped working on Xiaomi

Touch buttons do not work for two reasons:

  • Software errors. if they failed after installing a new firmware or application, remove it. In the case of firmware, try to roll back to the previous version. If you installed the Global version of the firmware, such an error is extremely unlikely, try rebooting the phone, or reset it to factory settings;
  • Physical impact on the sensor. the sensor is affected by the environment, it does not like water, dirt or mechanical impact. If the navigation buttons are located on the screen, try disabling them in the menu, then restart Xiaomi and turn it on again. If they are under the screen, and reboot manipulations do not help, you will have to carry the phone for repair.

Xiaomi has an engineering menu in which it is possible to test the operation of the buttons, but in our case this will not help, because if they work in it, but not during normal operation, you still have to figure out why this happens. Only Hard Reset is in your hands, but it doesn’t always help, and in the repair shop they can flash the device again, from scratch, with the latest version of the global firmware, which will solve the problem.

Buttons on Xiaomi (Redmi) volume control, power or touch navigation panel do not work

In Xiaomi (Redmi) smartphones, only the power button (lock) and volume control remain common. Navigation has become touch, or, as on models with a large screen, instead of buttons, gestures are used to navigate menus and applications.

often the mechanics fail, it is exposed to dirt, water and shocks that can break it.

If the regular buttons on Xiaomi have stopped working, but you are sure that water or dirt has not got inside, try gently pressing them 10 times in a row without applying physical force. In this case, something may have hit the contact pad and repeated pressing will move the obstacle away.

But most often you have to carry Xiaomi to the service to replace the button block, it is not expensive and takes a minimum amount of time, I do not advise changing them at home, for this you need to carefully disassemble the case, then disconnect the cable, and in some models you will have to remove the motherboard. without experience and a special tool, this is a lottery.

What to do if the buttons do not work, and there is no way to give Xiaomi repair?

A temporary solution to replace the functionality of the buttons will be the “Touch Assistant” function, which is built into the MIUI firmware.

It is able to duplicate buttons on the screen, and albeit with less convenience, but you will continue to use your smartphone as usual until it becomes possible to repair or replace it.

To get to the assistant, enter the general settings and click on the “Advanced settings” menu. Now select “Touch Assistant”. Activate it and click on “Shortcut Features” to customize the buttons you need. The assistant is called by clicking on a special shortcut, half-hidden on the right side of the screen. It is not possible to take a screenshot with it, but you will see it after activation.

Serious reasons

This method involves parsing the device and finding the cause of the problem. If you are not confident in your abilities, it is better to entrust this matter to a specialist. Following the following instructions, you can disassemble the laptop:

  • First you need to turn off the device.
  • Then you need to start removing the battery. As a rule, it is located in the body of the device, closer to the fold.
  • For your safety, unplug your device and remove all additional media, accessories, and other.
  • Using a screwdriver or any other narrow object, you must carefully unlock the plate latches. Finding them won’t be difficult. Latches are located along the edges of the structure. If you find it difficult to find the latches, refer to the instructions. It details how to safely open the device.
  • Do not make sudden movements when trying to remove the plate. It should be carefully lifted, holding on to the plastic part. After that, carefully remove from the laptop. If you see noticeable damage in the cable, then most likely this is the cause of the problem. He needs to be replaced. Do not touch the areas where the various wires are located. The user can damage them.

Now we should consider the device. Under the plate is a microcontroller. Its main purpose is to give and read signals that are given by buttons. Any dirt, dust, traces of moisture or other factors must be eliminated. Finding a microcontroller is not difficult at all. A loop was attached to it. If the user notices any damage (even minimal), the part needs to be replaced.

Using a thin object, it is advisable to very carefully detach each button on the keyboard. After that, it is necessary to carefully and thoroughly clean the buttons from dust and dirt. Damaged ones can be replaced.

After a complete cleaning, you need to check the keyboard again for performance. If the above manipulations did not help to fix the problem, it is best to contact specialists.

The keyboard assumes the possibility of blocking. There is a possibility that the user accidentally turned on the blocking. By pressing several key combinations (depending on the keyboard modification), problems can be solved. The most common options are FnNumLock, FNPause, FnWin. The button with the image of the lock can also help. It is not present on all keyboards. If this helps to restore the keyboard, the problem is solved.

To clean the keyboard, you can use a thin brush or a specialized vacuum cleaner for such purposes. These methods will be relevant if the cause of failures is dust and dirt between the buttons.

In rare cases, individual keys on the keyboard may stop working. Most likely, these are foreign objects. The reason may be dirt, food or water getting between the buttons, which leads to a breakdown.

Even if you’re not used to eating on your computer, the space between the buttons can get dirty over time. You can do the cleaning yourself or use the services of professional craftsmen.

Other Methods

If the above methods did not bring results, you can try to find the problem deeper. Failure of drivers or programs may cause the keyboard to malfunction. Using the following instructions, you can try to solve the problem:

  • Press the F8 key when turning on the computer. This will open the downloads menu. Some systems provide another key to open the menu. If the F8 key did not lead to the desired result, you can try pressing other buttons of the same name. If you successfully find the desired button, the Advanced Boot Options window should appear.
  • Next, select Safe Mode. For some systems, Starting in safe mode will be relevant. This method makes it possible to start the device without using drivers.

Now the user has to check the health of all keys. To do this, you need to run a special testing service. You can find it on the Internet by entering the Key-test query in any search engine. Any service will do. The main task of such programs is to display the status of all buttons on the keyboard.

If, when you turn on safe mode, all the buttons are in good condition, there is a problem with the drivers. In order to find the cause of the breakdown, you should check each of the drivers.

  • By updating the driver, you can try to fix the problem. To do this, you need to do the following:
  • Turn on the device in normal mode.
  • Go to the start menu and find Device Manager.
  • If you are unable to enter a request due to a malfunction of the buttons, you can enter the request in the browser. If there are gaps or errors, the system will automatically correct them and fill in the necessary letters. After that, the user just needs to copy the query and enter it in the search box.
  • Open System Preferences.
  • In the next window, you should mark the Keyboard column. V
  • Next, a list will appear where, among the many available actions, you should select Update drivers.
  • Next, the user needs to determine the location of the drivers. To do this, select the item Search for drivers on the network.
  • All of the above steps must be carried out for all available drivers.

If, according to the system, the drivers do not need to be updated, you should reinstall them. To do this, go to the device manager, where you can remove all outdated drivers.

Immediately after that, new ones will be installed in the system. If the process does not start automatically, you should restart the device. The system will start installing the drivers on its own.

There are also special programs aimed at finding outdated drivers and automatically replacing them. But if reinstalling the drivers didn’t fix the problem, the problem lies elsewhere.

What to do if the buttons do not work?

If the buttons do not work, then you will have to come up with a way out of the situation that will help you deal with the problem before the device is repaired. You can use the following methods:

Create a text file and copy there all the letters that cannot be typed on the keyboard. You can find them on the Internet;

Enable automatic word correction;

A malfunction in the keyboard is not a reason to write off a laptop in circulation. In most cases, the problem can be solved.

Why the touch buttons do not work on Xiaomi Mi4

When Xiaomi Mi4 touch buttons do not work, the owner experiences significant discomfort, as smartphone control becomes impossible. Such a defect may occur due to malfunctions in the device software, or due to damage to its electronic components.

You can find out what kind of failure caused the problem, hardware or software, by creating a “second space” available through the settings section. If the keys function in the created “space” the malfunction lies in the system software.

Errors in the software, their correction

Software problems in most cases can be fixed by the owner without the use of service assistance. In order to have access to phone management for the period of repairing the breakdown, you should use one of the utilities that display a separate virtual panel with the main keys (Back Button, etc.).

  • System hang. It happens that the software slows down, stopping the functionality of the control keys. The device is restarted.
  • Lack of memory. When running demanding applications, a large number of downloads and other complex tasks that fill the amount of memory, it may not be enough. All jobs are canceled or restarted.
  • Operation of applications that are not included in the pre-installed package. Some programs that the user has installed on their own may have access to the phone’s navigation and block the operation of the keys. All newly installed utilities are found, stopped/removed one at a time, checking the functionality of the navigation bar.

If the above methods did not work, the situation can be corrected by resetting to factory settings. You must first create a copy of all data on the phone.

  • Faulty update set and/or system software (firmware) version. Such defects are not subject to correction, non-functional software is replaced with a workable one.

There is a non-trivial way to return the functionality to the navigation keys: if the owner is able to run the built-in utility for the initial setup of the gadget, then after this procedure and the issuance of the necessary permissions, the keys can work. It is recommended to do this only if you have special knowledge and skills.

What to do if Xiaomi Mi4 touch buttons do not work due to breakdowns

When Xiaomi Mi4 touch buttons do not work due to damaged parts, this happens due to physical external influence on the device.

  • Fall impact, direct impact, squeezing. Cause fractures, splits and cracks. They are practically not subject to repair, the cost of such restoration is high, and the restored parts do not last long.
  • Wetting: direct penetration of moisture, its vapors, condensation inside the case. From moisture, metal elements are oxidized, the electronic signal loses the ability to be transmitted, which is why the lower buttons do not work for Xiaomi Mi4. Without consequences, it is possible to remove moisture from under the case only if there was little of it, and its effect was short.

It is advisable not to repair broken, wet modules, but to replace them with serviceable ones, since the replacement will cost a little and the device will function for a long time after it.

You can profitably purchase reliable parts on the GadgetParts website: inexpensive original parts, or factory analogues that have an even lower price with identical quality, safety and warranty period (1 year). Purchases are delivered to city addresses cheaply or free of charge. Orders are transferred to the regions with a transport service with the function of tracking its path on the website.

For customers, a separate section provides step-by-step instructions for self-replacing elements.

Why the buttons on the Xiaomi Redmi smartphone do not work

The Chinese manufacturer Xiaomi offers its customers two main lines of gadgets:

Home button, back button, recent button not working || fix problem easy ||redmi mi salutation

  • Mi (including MiPad, Mi Note, etc.). These are top modern devices in various sizes;
  • Redmi (this includes many models from Redmi 1s to Redmi 4 X).

All of them have a wide range of features at an affordable price, perfectly combined with performance.

Despite the fact that the Redmi series brings together budget smartphones, the company pays a lot of attention to the build quality and operation of its devices. Therefore, even for little money, anyone can get a really high-quality gadget.

But, as always, among any serial models there are devices with a factory defect, or a breakdown can happen during operation (after all, no one is immune from this).

So, some users on the network complain that after a while of use a very unpleasant bug appears, the power button on the Xiaomi Redmi smartphone does not work.

Here it is worth noting separately that the main elements of interaction with the device are touch-sensitive (these are the “back”, “home” and “menu” buttons), and the hardware ones are volume control and turning on the smartphone (screen lock).

The only exception is Xiaomi Redmi Pro (it is equipped with a hardware Home button combined with a fingerprint scanner).

Complaints happen to both those and those, but in the case of the latter (hardware) they are much more common due to their obvious vulnerability (any movable connections are at high risk of moisture ingress, mechanical failure, etc.).

In addition, touch buttons can be quickly replaced with alternative “soft” (software) keys. For example, using the Button Savior app or similar.

The lower part of the screen will be used as an alternative to the buttons on the touch panel (completely duplicate the location and functionality).

Therefore, we will dwell in more detail on the hardware buttons in Xiaomi Redmi series smartphones.


Calibration is an operation that allows you to adjust the response of the sensor. It is needed to prevent typing errors. The operation is carried out if, when you press the display in one place, a completely different area reacts.

The execution algorithm is different for gadgets from different manufacturers:

When finished, check if the issue is resolved. If not, go to the next paragraph.

Reload and reconfigure

The malfunction may be due to a software failure. Reboot: hold down the volume and power keys for 10-15 seconds. Wait for the operating system to start and try again.

If this action does not help, perform a factory reset. Go to the menu “Settings” → “Backup and reset” → “Reset phone”. Section names may vary slightly for different models.

Create virtual keyboard

There are applications that create an imitation of smartphone buttons. One of the popular ones is Back Button. Install it through the Play Market, and use the virtual keyboard instead of the usual one. But this method is a temporary measure. It is unlikely that you will like to use the virtual keyboard for a long time.

Contact service

If the touch buttons at the bottom of the phone screen do not work, take it to a service center. The master will diagnose and find out the cause. It’s possible the connector came off due to the impact. The malfunction can also be caused by damage to the cable. In any case, you can not do without the help of an engineer. Repair will depend on the model: in some smartphones, only the cable can be replaced, in others, the entire display module.

Breakage of one of the display elements

Simple at first glance, the Xiaomi screen consists and functions of many details: backlight, display (light filter), protective glass, touch substrate, driver, cable, controller, power supply and many others.

You can determine that the breakdown turned out to be at the physical level by trying all the ways to fix software failures. If none of them led to a positive result, then something is broken and you need to carry the phone to a service center.

Screen sensor diagnostics in the Xiaomi engineering menu

Xiaomi (Redmi) smartphones have an engineering menu designed to test functional elements.

To get into the engineering menu, launch the Phone application, and instead of dialing the phone number, dial the following: ##6484##. You will find yourself in the engineering menu, now find the “Touch sensor” item and click on it. You will see a black screen with a grid, touch the display and make a few movements. Behind the finger on the screen should be a trace exactly repeating the movement of the hand. If it is not there, or if the track is not even, then the sensor is not working well and needs to be repaired. If the trace remains exactly where you swiped your finger, then everything is in order with the hardware stuffing and you need to look for the cause in programs or settings.

External causes of sensor failure on Xiaomi

The testing procedure includes the following actions:

In the settings menu, go to the “About phone” subsection.

In the menu that opens, click “Touch Sensor”.

Back, Recent & Home Button Not Working!! Problem Solved Without Changing Touch Screen [Redmi]

We touch the display and, without lifting your finger, we drive along it.

When identifying “dead” areas, activate “Management with one hand”.

Important! We strongly recommend that you purchase only original components from the manufacturer. They are produced using special Xiaomi technologies and undergo a comprehensive quality check.

This is the rarest cause of screen sensor failure, but it cannot be written off.

A phone can get a powerful static electricity shock when it comes into contact with an old TV, when it comes into contact with a central heating battery or any metal object, especially in winter.

Even in contact with the car body in winter after a long trip.

Girls in the cold season like to wear woolen socks, a bathrobe or other products made of natural pile at home, such clothes can accumulate a serious charge of electricity, and the moment you reach for the phone, a spark jumps that can disable the Xiaomi sensor.

This breakdown can be diagnosed and corrected only in a service center.

Xiaomi Redmi 5 buggy sensor freezes after installing the program, but after uninstalling, it also slows down. What to do?

The touchscreen on Xiaomi Redmi 5 constantly hangs. In the advanced settings, I set it to display touches on the screen. As a result, when hanging, it shows that there is a touch on the top of the screen. Has anyone solved this problem.

Keyboard freezes when entering text on Xiaomi. How to solve the problem?

The sensitivity of the Khiaomi touchscreen drops while lying on the table. I take it and it does not react, with a stronger pressure it works. How to restore it?

software ways to fix problems


If the sensor is not working partially, download the Rebooter app to help you quickly reboot your device. If the sensor is completely unresponsive and the smartphone has a removable battery, just remove the battery for a couple of minutes.

With devices that have a non-removable battery installed, you need to do a little differently.

Xiaomi device owners can hold the on/off button for 20 seconds or longer and the smartphone will restart or turn off. If this does not work the first time, try again, but hold the buttons longer. Owners of devices of other brands with a built-in battery should also try the above options.

If pressing the buttons does not give any result, wait until the battery is completely discharged and take the device in for repair.

Removing the memory card and SIM card

Sometimes a memory card or SIM card is to blame for a touchscreen malfunction. To check this, turn off Xiaomi Redmi, remove both cards. After reboot, check if the problem is gone.

Through safe mode

Turn off the device completely. Then press the power button and do not release it until the smartphone logo appears on the screen. After that, release and press the volume down button. Release it when the device boots up and “Safe mode” will appear on the bottom left of the screen.

If no problems with the sensor are found in safe mode, then the problem is one of the applications that needs to be uninstalled or updated to the latest version.

hard reset

This is a full factory reset of the Xiaomi device.

Before resetting your phone to factory settings, do not forget to backup all important data stored on the device.

Display calibration with third-party programs

The Play Market has applications that can be used to calibrate the touch display, improving its performance. Reviewing all the applications will take too long, so we will focus on one of them, which received the highest score from users.


This Android app does two things:

  • conducts testing and issues a report on which fragments are not used, why the accuracy is low and the screen sensitivity is lame;
  • fixes errors automatically.

The application has an additional function. it allows you to change the orientation of the screen. You can select the area, when pressed, the response will occur in another part of the display.

How to fix if the device is physically damaged

Next, we will analyze ways to test the screen and restore it.

TSP Dot Mode and TSP Grid Mode Tests

To conduct this test, you need to get into the Xiaomi engineering menu. To do this, dial the service code. It may be different for different manufacturers and phone models, try these options:

  • TSP Dot Mode. allows you to check the screen in “dot mode”. In the place where you will touch the display, there should be a cross.
  • TSP Grid Mode. testing takes place in the “grid mode”. The screen is divided into several rectangular parts. When a particular rectangle responds to touch, its color will change.

This test will tell you which part of the screen has a problem.

Developers do not advise trying to repair the phone on their own, as this requires certain knowledge and experience.

Tapping around the perimeter of the screen

This is the easiest way to test the display, which does not require installation of programs or other complex manipulations. Just gently press your finger across the entire surface of the display, especially in problem areas. Start with low pressure and gradually increase. Then slowly decrease the pressure.

Launch the keyboard and press each key. Try moving app shortcuts across the entire screen. In this case, pay attention to the sensitivity of each section of the display. Pause at the corners of the display, focusing on the bottom. Such testing will give you all the information about the sensitivity of the touchscreen.

Dry after getting wet

If moisture gets into Xiaomi, follow these instructions:

  • turn off the power;
  • remove the battery (for devices with a removable battery);
  • remove the SIM card and flash drive;
  • wipe the device with paper towels or a cloth that absorbs moisture well;
  • remove headphones, cases, film or glass from the screen;
  • place the smartphone in a bag filled with rice. Leave the device in this position for 12 hours. During this time, the croup will draw all the liquid out of the phone.

If the procedure with rice does not give the desired effect, contact the service center.

Check loops

A problem with the cable can be determined even without disassembling the phone. Sensor malfunctions are one of the signs of such a problem. Pay attention to the following signs:

  • the smartphone began to “slow down” during operation;
  • the device turns off when you unlock;
  • camera malfunctions.

If, in addition to problems with the sensor, the above appeared, then there are definitely problems with the cable. But you should not repair it yourself, because for this you need to be well versed in the smartphone device.

Sensor Replacement

If your smartphone does not use OGS technology, you can try to replace the sensor yourself. To do this, you will need the following tools and fixtures:

  • a set of small curly screwdrivers (available for sale specifically for smartphones);
  • mediator, spatula, plastic card;
  • silicone suction cup with ring or loop;
  • ordinary hair dryer;
  • glue B-7000 or equivalent;
  • thin rubber gloves.
  • Disassemble your smartphone.
  • Heat the display with a hair dryer around the entire perimeter to a temperature of about 70-80 degrees. Pick up the heated screen with a suction cup, and pull it off the case.
  • Install a new sensor. Prepare it by removing the protective film from the inside. Apply a thin layer of adhesive over the entire area of ​​the seating surface. Put the sensor back in place and gently press it down. You can put a small and flat object on top of the screen, weighing no more than 300 g, so that it sticks better.
  • You can collect the phone. Connect the cables, fix the internal threaded connections and install the external parts of the housing.

If you are not sure that you can handle the sensor replacement yourself, take the phone to a service center. Self-repair of the device will void the warranty on the smartphone.

How to save data when the display is not working

If the Redmi screen stops working completely and you want to keep the files on your phone, you will have to use a regular PC and a special program.

Broken Android Data Extraction

iSkysoft has developed a program that allows you to save or restore the necessary information from broken phones. To do this, install the Android Data Extraction application on your computer and follow the instructions.

  • Connect your smartphone to your computer with a wire.
  • Open the program, section “Data Extraction” (Damaged Devices).
  • Select the type of file to recover.
  • Indicate the current state of the smartphone: a) “Sensor does not work”; b) “Black/broken display”.
  • Enter the smartphone name and model. Then click “Next” and “Confirm”.
  • Turn off your smartphone.
  • Continue the process of saving data on the computer.

The touch screen of modern smartphones is quite fragile, so it can easily fail. You can always try to repair the touchscreen yourself or take it in for repair if the breakdown is difficult.

Answers to popular questions from readers: EvgenySpecialist in setting up smartphones and tablets OC Android If you want to ask an expert a question and get a quick answer, click on the button ask a question or leave a comment on this article Xiaomi sensor is buggy (sometimes it works, sometimes it refuses), it may be a problem with the firmware. Even the user did not change or update the factory version, it is possible that a pirated firmware is installed on the purchased device. Try to reflash the device by installing the official global version. Recently bought Redmi 8, the screen stopped responding to touch, what should I do? This is an extremely rare occurrence, since the brand’s products are distinguished by their reliability. The fact that the cause of the malfunction lies in a factory defect will be indicated by the failure of the touch buttons to work, the lack of response to a certain part of the screen, recognizing scrolling as pressing, etc. The device can only be restored by replacing the entire display module. If your smartphone is under warranty, we recommend that you take it to the mobile phone shop where you bought it

Modern smartphones with a touch screen that occupies almost the entire front panel are convenient, functional and presentable. But the problem with the sensor on the Xiaomi smartphone is quite common. For some users, the reaction to touch does not work both over the entire area or in separate areas, the touchscreen works “from time to time”, the buttons stopped working on Xiaomi – these are just some of the problems. Consider the main causes of sensor failures and how to eliminate them.

Screen calibration

In rare cases, the screen sensor calibration fails, the first symptom of this ailment is incorrect recognition of gestures and touches on the screen.

When typing, you click on the letter “A”, but instead of it, “P” is displayed on the screen, standing next to it. This means that the sensor is working, but it is not calibrated.

To calibrate, you need to install an application from the Google Play store. Go into it and enter “Screen Calibration” in the search bar, then select the application you like and launch it. After calibration, restart your phone and check gesture recognition.

Crash in settings

I found on the net a mention of one tricky setting in Xiaomi, which can lead to problems with the sensor.

To check it, go to the general settings, find the “Advanced settings” item, enter it. Now we need the “Specials” menu. Opportunities”. In the list of options, find the item “Delay when pressing and holding”, its value should be “Small”. If it’s different, change it. Then restart your phone. For many users, changing this setting returned the sensor to normal.

The failure occurs under the influence of the following software failures:

  • use of third-party applications from dubious sources;
  • overloading the internal memory of the device;
  • touch screen malfunctions;
  • unstable or inappropriate firmware version.

The reasons can also be component: the touch buttons fail after the smartphone falls from a great height, a strong blow, or prolonged exposure to moisture. The problem can be caused by sudden changes in temperature, punching the screen, serious pollution. If the protective film was inaccurately pasted, or the display was replaced incorrectly, this may lead to a malfunction of the buttons.

To determine what exactly caused the breakdown in your case, try all the methods in turn.

Action algorithm

To reboot, remove the battery if it is provided by your smartphone model. After a few minutes, return it to its place, and turn on the gadget using the button. If you can’t get the battery out, try holding down the power button for a few seconds, or simultaneously 3 buttons. power, volume up and down. You can also wait until the battery is completely discharged, and then charge it and turn on the device.

If the internal memory is overloaded, the device may “freeze” or give system errors. Clear the app cache: Go to Settings → Apps and delete the cache for each installed program one by one. You can also download special utilities to clear the cache.

Take care in advance to save the necessary data: after the reset, they will be deleted. After that, go to “Settings” → “General” → “Reset to factory settings” and confirm the operation. On some models of smartphones, the names of the sections may differ.

To calibrate the screen, go to “Settings” → “Display” → “Display” → “Screen Calibration” and follow the instructions that will appear in the menu. On some smartphone models, this option is located in the “Settings” → “Language and keyboard” section. If the issue is related to the touch screen not working properly, calibration may fix the issue.

Contact the service center

Mechanical damage or wear of parts can be repaired at a service center. The master will diagnose and be able to find out what exactly caused the breakdown. If necessary, change settings or replace faulty parts.
