Lost sound on Xiaomi Mi a1

how to increase the volume on any Xiaomi phone

First of all, make sure that your headphones are working properly and that a reliable connection has been established with your phone. If you are using conventional wired headphones, inspect the connector: it may be dirty or loose. For wireless headphones, check if the Bluetooth connection is correct.

If you don’t find any issues, move on to the next method. The fact is that MIUI has an option to automatically improve the sound quality in the headphones, and it is precisely this that often affects the volume.

  • Go to phone settings and select “Advanced settings”.
  • Find the “Headphones and sound effects” section.
  • Disable Mi Sound Enhancer (if enabled).

The system automatically detects the type of headphones connected and adjusts the sound settings accordingly. For better volume, you can choose one of the presented types yourself, or disable the function altogether.

In addition, the included sound enhancement activates the built-in equalizer. Unlike the previous option, the equalizer can help boost the volume. To do this, increase all frequencies to the maximum value, however, this may spoil the sound quality.

If you have root access, then you can use another method that is guaranteed to increase the volume of the sound.

The method is suitable only for experienced users who are confident in their actions and understand that they are doing everything at their own peril and risk.

  • Open Root Explorer.
  • Find and open the mixer_paths file (at: /vendor/etc/mixer_paths.xml).
  • In the path name=headphones-ce line, increase the value from 72 to 82 (you can put even higher numbers if necessary).
  • Reboot your device.

If none of the methods helped to achieve the desired effect, it remains only to turn to specialists.

Quiet speaker

As for the conversational dynamics, then if you can’t hear the interlocutor, you first need to:

  • check that during a call the volume slider is raised to the maximum level;
  • make sure that the speaker is not broken and is functioning normally (using the engineering menu, as described above).

If these actions did not lead to anything, then you can try to make changes to the system files.

This operation requires root access, as well as confidence in your knowledge and skills.

Change the number 11 to 16, then save the file and restart your smartphone. Speaker volume will increase.

Increase speaker volume

You need to start with the most banal actions: make sure that your phone is not muted. You may have accidentally set the mode to “Silent” or “Do Not Disturb”.

When adjusting the volume using the side buttons, three sliders are displayed: ringtone, alarm clock and multimedia. Users often confuse these modes and lower the sound of the function that they did not want.

If the speaker still sounds too quiet, it may have been damaged. To check its status, use the test, which is located in a special engineering menu. This menu is hidden from ordinary users, so there are two ways to enter it:

In any case, you will see a gray screen with five buttons:

We are interested in the “Single item test” section. As the name implies, at this point you can test any particular option. We go into this section and look for the “Receiver” button, which denotes the main speaker. After pressing the button, the phone will play a test melody, after which it will become clear to you whether the speaker is working or if it sounds too quiet.

To check the status of the conversational speaker, press the “Speaker” button

Once upon a time, the engineering menu allowed you to manually adjust the volume values, but on new firmware (starting with MIUI 9.2) you can only test the state of the speaker and understand if it works fine, or the sound is reduced due to some technical or operational reasons.

Curiously, sometimes on flagship devices, the volume of the speaker can be reduced due to legal restrictions.

The fact is that some European countries strictly control the permissible level of noise produced. Thus, Xiaomi cannot sell its smartphones in these countries if the speaker sound is too loud.

However, this strange limitation can be bypassed very simply:

Check the volume: if it has increased, then change the time zone and use the phone as usual.

In smartphones that have a face unlock function, changing the region may not affect the increase in volume.

If the volume of the call in MIUI is constantly lost

A rather common problem on Xiaomi smartphones, which has nothing to do with the functioning of the speaker itself. The fact is that MIUI has several options, due to which the sound of an incoming call is constantly muted, and it is not so easy to find and disable them.

To check if these options are activated for you, you need to go to the settings, then select the “System applications” section, and then click on the “Phone” line (on some models you need to select “Calls”). A menu will open, in which you should select the item “Incoming calls”. There are several settings here, of which you need to pay attention to the following:

  • “Volume up”. the sound rises from soft to loud every time, which can be inconvenient if you answer the call almost immediately;
  • “Mute the call when picking up”. from the name it is clear that the volume goes down if you hold the phone in your hands;
  • “Mute the beginning of the call”. works if you are called from an unknown number.

It remains only to disable these options, or leave some of them if you see fit.

How to listen to the radio on Xiaomi phones with MIUI

If we have a mobile phone with MIUI as the Xiaomi setting layer, it will be very easy for us to be able to listen to the radio, we just have to follow the steps we show you. First we move around its screen and run until we find the tools folder where we go and see the pre-installed FM radio application. A simple touch on it will start playing, although we will probably have problems tuning into the station to improve the signal we will have to resort to headphones that make the antenna through the audio jack.

Once we plug in the headphones, we can press the left and right arrow keys to switch between automatically detected stations. If we prefer to know all the stations, we just have to press the button in the center and we will see the list of stations. If we want to recognize our favorite stations in the future, we can set them up with our own name in the three dots in the top right corner, as well as change the audio output to the speaker of our mobile phone.

How to listen to the radio on all Xiaomi phones (MIUI and Android One)

In many cases, radio is still the best option, whether for listening to music, for breaking news, or for tracking minute-by-minute sports among a variety of other programs. Fortunately, in Xiaomi phones we have the possibility to listen to the radio and we want to show you how to do it.

Not all Xiaomi phones integrate the well-known MIUI customization layer, which, among other things, allows us to record screen and sound in Xiaomi without having to download anything. Some of its most popular models include Android One, where we will also be able to listen to FM radio although the process can be minimally complicated.

Listen to radio on Xiaomi phones with Android One

Xiaomi phones with Android One initially had more difficulty so we can tune in to our favorite radio, but that has changed. The move from complex code has hidden one of the features that most users want from a simple app.

Xiaomi Mi A1, Mi A2 and Mi A2 Lite

If you have one of the first known Android One by Xiaomi which received such a good reception in front of the public, you will be interested to know what steps you need to take to listen to radio without internet on mobile phones such as Xiaomi Mi A1, Xiaomi Mi A2 and its Mi A2 Lite version.

  • The first thing we will do is open the phone app.
  • Then we write the code: # # #
  • Slide to the end of the screen that appears.
  • We play on FM radio
  • Connect headphones via audio jack.
  • The radio will automatically start playing.

Xiaomi Mi A3, with built-in radio

In Xiaomi Mi A3, everything changed when you started watching the built-in FM radio like in Xiaomi phones with MIUI. We just have to find the app and connect the headphones to the audio jack to start enjoying our favorite radio stations.

How to increase the speaker volume through the USSD settings on the phone?

The algorithm of actions given below will be needed when the manufacturer made a mistake with the settings. During the setup process, you should be extremely careful not to knock down other options. It is suitable for older MIUI firmware.

After loading the screen, find the line “Hardware”. “Audio”. A large list of options will open. Requires the first five.

Important! Configure only functions with failures. You should not take on the “Headphones” if the “Speakerphone” is acting up.

Click on the line with the problem and from there enter the “Headset Mode”.

In “ring”, “media”, “sph” set in turn a numerical increase in volume. In the “Level” item, select a value from 0 to 255, where 0 is its absence, and 255 is the maximum value. When setting the value, do not set the maximum, otherwise the component will deteriorate completely.

How to increase the volume on Xiaomi through Recovery?

This method is best used by those users who are confident in their technical knowledge. Before proceeding with manipulations, you should back up your data. Manipulation requires root-rights.

The necessary setup utility can be found on the Xiaomi official website.

Download the program and save it to the root of the internal memory. Then execute the algorithm of actions:

Enter the device into recovery mode and connect it to the PC.

Find the desired archive with the program and specify the path to it on the computer in the input line.

Install each item separately, otherwise there will be an irreparable failure in the system.

If you need to repair your smartphone in version MIUI 9, you do not need to download or install anything. In the “mixer paths” file, it’s easy to debug. For work, you will need a conductor with access to the system. You can use the ES utility. After the editor with the canvas of the system code is opened, find the lines:

Change the numbers “11” to “16”. Save and reload.

Before you eliminate the breakdown, it is worthwhile to accurately determine the cause of the poor sounding of the speaker. It depends on how to fix it.

Low factory settings. If the smartphone had poor audibility immediately after its purchase, then most likely the manufacturer set the parameters incorrectly. Fix the defect yourself.

Mechanical damage. It may well be that when Xiaomi fell from a height onto a hard surface, the speaker was damaged. It will not be possible to understand this immediately, since usually the sound begins to disappear after a while. In this case, you will need the help of a specialist and most likely a replacement of the component.

The maximum load on the internal memory. When the “native” drive on the Xiaomi device is left with almost no free space, then the sound signals begin to come with great noise.

Incorrectly set settings. The user can accidentally knock down the parameters and set instead of “normal”, “quiet”. This is the most primitive failure, solved in a few clicks.

How to set up the option in the headphones?

Either of the above two methods is suitable for troubleshooting. But if they did not help, then you need to check for the presence of several more factors of weak sound:

The silent communication mode is set (“Quiet”, “Meeting”). In the menu, return the phone to normal mode.

Poor contact of the Xiaomi smartphone with the wire from the headset. There is a mechanical failure of the socket or cord.

If none of the actions helped, then the only thing left is to replace the component. It’s most likely corrupted.

The sound on the Xiaomi phone disappeared, we are looking for the reason in the software part

If you are sure that the phone has not been subjected to unwanted physical impact recently: it has not been exposed to rain, it has not been dropped, you have not hit it on hard surfaces, then the probability that the lack of sound lies somewhere in the software part is high.

Below I will briefly describe the steps that will help if the reason was somewhere in the firmware or in the software settings:

  • Restart your smartphone. This is a simple but effective method that helps in many different situations;
  • Check basic settings. Make sure that you have not turned off the sound in the settings, you can do this by pressing the volume buttons and expanding the menu to full view;
  • Update the firmware to the full version. If you have been using your smartphone for some time, it is likely that firmware updates were released for it and, most likely, you installed them when you received a notification about this. This is called an over the air update, its peculiarity lies in the fact that it includes only the required software part, which has been modified compared to the version of software that is already installed on the phone. And those modules that have not changed are not included in the installation package. This allows you to significantly save on traffic, which is especially important in cases where you use cellular networks to download the update. However, such a modular design can sometimes fail after installation, so I recommend installing the same firmware version, but in full version. How to do it is described in detail here. Do not worry, the procedure is automatic, you just need to run it and wait for it to complete, your data will not be deleted, everything will remain safe;
  • Reset to factory settings. This is a last resort and I do not recommend using it until you have tried all the other methods. I do not advise, because all data will be deleted and it will not be possible to return them, unless you make a full backup either to the cloud or to your computer before starting. However, although this is the longest method, it will also allow you to hope that the sound will return, because it deletes all settings, applications and files that are not related to the firmware, which means that even if there was a failure somewhere, it will disappear and the full functionality of the smartphone will be restored.

On the Internet, I met additional options for why Xiaomi lost sound and a description of the recovery method, but they either look far-fetched and frivolous, or are related to five-year-old smartphones. Now it’s impossible to even find the menus and options that are described in the articles, because the menu structure in modern MIUI has undergone significant changes and modifications.

Xiaomi (Redmi) lost sound, how to return

If sound is lost on Xiaomi (Redmi), this is not good, and the point here is not that it causes inconvenience, but that, as a rule, it is difficult to determine the exact cause. Hence the difficulty arises with the diagnosis and choice of sound restoration methods.

I will describe the most common reasons, and if the sound disappeared on Xiaomi in similar circumstances, the methods described will probably help to return it.

But even before you start trying to restore, I want to warn you that most likely you will have to contact a service center. Xiaomi smartphones are designed and created with the expectation that they will be used by people, including those with low technical training. For this reason, most of the functions work automatically, the user is left with only the very top to be able to change, and if you did not touch the settings, then it is very likely that the reason for the lack of sound lies somewhere in the depths of the firmware or lies in the physical breakdown of the speaker.

If sound is lost on Xiaomi or Redmi, it is necessary to exclude physical damage

Two things usually break: the speaker and the motherboard. We will not be able to check the motherboard, for this you need to completely disassemble the smartphone, and additionally you need special equipment and, most importantly, knowledge.

Therefore, we turn to checking the performance of the speaker.

To do this, we need to get into the engineering menu. Don’t worry, there’s nothing wrong with that, this menu was created specifically for quick but reliable testing of all major Xiaomi components.

To get into it, open the Xiaomi general settings, find the “About phone” menu. Now we need the line “Kernel version”. in MIUI 12, it hides inside the All Options menu. Click on the version 8 times in a row, and you will automatically find yourself in the engineering menu. Now look for the line “Speaker”. The test will start, unfortunately, I cannot say with high accuracy how it will look, because how it works and is called depends on the model to model, and the MIUI version. In my case, on the Mi 9 SE phone with firmware 12.0.3.0, the test looks like this: after entering the “Speaker” menu, the maximum speaker volume is automatically set and the female voice starts pronouncing two numbers in English. If you hear them, it means that the speaker is physically healthy, and you need to look for why the sound on Xiaomi has disappeared in a different plane. For the test to be considered passed, you need to click on the numbers that say the voice, but this is not so important for us.

How to clean the speaker on Xiaomi

Another reason that you do not hear sound on Xiaomi may be the banal pollution of the speaker hole. It is protected by a metal mesh with small cells so that even small contaminants do not penetrate the protection.

But at the same time, this is a minus, because. small cells can quickly become clogged with dirt and dust, making the sound almost inaudible.

There are two main sources of sound on the phone: the earpiece, which is located on the upper end in the place that you put to your ear for a conversation, and on the bottom, next to the USB jack, all other sounds that are not related to telephone conversations are heard from it.

Examine them carefully, and if you see that there is something there, carefully remove the dirt. I recommend taking a vacuum cleaner, set it to the minimum power, if possible, put the pipe next to the speaker, but do not lean closely, and slowly, using a soft toothpick, start prying off the dirt. A vacuum cleaner is needed so that what you remove does not fall below the grate, but, on the contrary, is removed outside.

During the procedure, do not rush, act carefully so that the toothpick does not break the protective film and does not fall behind it, damaging the speaker.

If all the methods listed above did not work, then the reason that the sound disappeared on Xiaomi remained a mystery to us and you will need to contact the service center to diagnose and fix the problem.

Take the phone and inspect the audio input (3.5 mm). Clean off the dirt with a wooden toothpick. Do not use metal or sharp objects. Foreign debris is a common cause of contact closure.

We hope that the recommendations will be useful to you.

Telephone repair

First option:

  • Go to the settings menu;
  • go to the permissions section, open messages;
  • select this item by checking the box.

Manipulations usually work, and the device starts playing files in audio format.

  • We select applications in the phone;
  • look for messages and delete the amount of data;
  • the following window pops up.
  • Go to messages, and allow access to audio recordings.

Disassembly of the device

If the Xiaomi phone is under warranty, it is easier to take it to a service center. The dismantling of the back cover of the smartphone is carried out with an old plastic card. We advise you to watch videos on YouTube showing the analysis of your phone model. We carefully disassemble the device and get access to the desired microphone (upper or lower). Check the integrity of the contacts. If necessary, treat the contacts with an eraser or heat the soldering place with a special hairdryer. Further actions depend on the specific model of the device and its element base. If everything is done correctly, then in 30-40 minutes you will return high-quality sound to your mobile device.

Detailed algorithm:

  • We take out the compartment with the SIM card;
  • snap off the cover around the perimeter;
  • we see the fingerprint scanner panel, and carefully disconnect this tape;
  • unscrew the bolts on the protective panel;
  • we clean the contacts with an eraser, we use a soldering iron;
  • install a new speaker (if necessary).

Attention: disassembling a Xiaomi phone will void the manufacturer’s warranty.

Sound disappeared on Xiaomi: causes and solutions

No sound on Xiaomi phone. Causes of breakdown. How to solve the problem with a Xiaomi smartphone yourself.

Xiaomi brand smartphones are conquering not only the Chinese, but also the Russian market. Phones are famous for their loud sound. But sometimes the speaker’s work is disrupted: the sound disappears when incoming calls or SMS come in silent mode. We will analyze typical breakdowns of a mobile phone and ways to solve an error that has arisen.

Xiaomi lost the sound of incoming calls

You do not hear the voice of the interlocutor when you receive a call, and it’s not a software error? The reason may be moisture ingress or mechanical damage to the case. For example, the speaker antenna has oxidized. Then the phone must be disassembled and cleaned. If the case is damage to the antennae, then disassemble the Xiaomi smartphone and bend the mustache back.

Please note that dust can often be found in the audio jack, due to which a short circuit occurs. Without turning on your phone, clean the socket.

The program could also reset standard commands when loading the player, for example.

  • We type a command consisting of symbols and numbers “##3646633##”;
  • click on the section “Hardware” and “Audio”;
  • set the silent mode (for example, speakerphone);
  • you should press “Headset Mode” and click on “Type”;
  • three elements will appear in front of you. “Ring”, “Media”, “SPH”. Set the volume level for each.

You can install a special program that will configure the system itself. Download “Sound About”. Go to “Media|Audio” and the “Speaker” function. A window will open where you need to click “Phone Call Audio”. It remains to wait for the session to end, and the signal will work again.

Another way

  • We are in the settings menu;
  • choose a sound. Next, click on the ringtone;
  • you will see possible options for melodies;
  • restart your Xiaomi phone after installation.

Attention! We are not responsible for all your manipulations with the phone, performed according to our instructions. Repairs must be carried out by a qualified technician. Contact our Repair Service.

When the quality of the pixels is determined, and among them it was possible to detect “burnt out”, you can start looking for applications that will correct the situation:

  • JScreenFix is ​​easy to use, you need to use the Fix Stuck Pixels button to get started. The developer promises 30 minutes to complete this operation, but the service center masters recommend leaving the devices. At least 10-12 hours for a more complete check;
  • Pixel Fixer: Another program similar to JScreenFix. To restore the pixels, you also need to click on the green button;
  • “Dead Pixel Treatment”: The platform not only tests a mobile phone for dead pixels. And then “heals” them, but at the same time reveals other defects in the display.

When using applications, it is recommended that the device not be disconnected from the chargers for the duration of the “treatment”. During pixel processing, the smartphone is constantly on, so the charge may not be enough.

Screen microcracks are fraught with a break in the power circuit. If this happens, then you will have to change the screen. Fortunately, in China they are several times cheaper.

It happens that the malfunction lies in the incorrect installation of the SIM card or flash drive. Try to take them out and see what happens.

A card with problems can be repaired by restoring broken clusters using a PC.

If shaken, a badly exposed plug from the display may fall out. What will entail disabling the image transmission module, or partial shutdown.

Remove the cover of the device, and plug the cable into the socket. If it is inserted, then take it out and insert it. In this case, do not forget to disconnect the power cable from the battery.

Speaker not working

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. Above we gave advice. to 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.

If that doesn’t help, check your equalizer settings. If they are at zero, then the sound will not come into the microphone. The solution is to equalize the value of this parameter.

If the signal goes only to the headset, then you need to connect and turn off the headphones. Hold down the volume up key. Repeat the procedure several times. If it doesn’t help, then the connector is cleaned with air or a chemical composition like alcohol.

These recommendations helped owners of Xiaomi smartphones.

  • Reboot the device;
  • wait for Xiaomi phone to be 100% discharged and charge it again;
  • install the latest update.

How to check Xiaomi smartphone for hardware failure? Everything is simple. Launch any application that should play the signal (for example, the player). If it is present, then from a technical point of view, the device is in good condition. Another thing is if the phone fell from a great height, was in a room with high humidity for a long time, then you should definitely contact the service center.

Software failures

If sound loss occurs periodically or interference and noise appear from time to time, then it may be necessary to update the firmware, especially if a custom version of the shell was previously installed. The following troubleshooting options may also help:

If, after updating the firmware, the sound on SMS messages disappeared, then the problem can be solved in several ways.

Option 1

In the settings menu, go to the “Permissions” section and find the tab called “Application Permissions”.

In the new window we find the SMS category and move the slider to the active position opposite the “Messages” section.

Option 2

In the settings we find the “Sound and vibration” section and check that the slider opposite to all items is moved to the active position. You also need to check that a melody is selected for incoming SMS.

No sound on Xiaomi Mi 9: causes and solutions

Sound problems on the Xiaomi Mi 9 smartphone are usually associated with software failures or mechanical damage to the sound module. If the device has been subjected to physical impact (fall, shock) and signs of damage are clearly visible on it, then it is advisable to contact the Xiaomi warranty service center at #WF_CITY_PRED#, where the device will be diagnosed and, if necessary, the sound card or other elements will be replaced.

In most other cases, you can try to solve the sound problem on Xiaomi Mi 9 yourself.

No sound on incoming calls

This malfunction is usually manifested by the fact that when an incoming call, the Mi 9 smartphone vibrates, but there is no sound. Initially, you need to make sure that the cause is not moisture or some kind of mechanical damage.

In some cases, a simple cleaning of the speaker from dust can help, for which you will have to sort out the mobile device.

Another common reason is the installation of some kind of application for playing audio files or a music player. If the loss of sound was detected immediately after installing these programs, then you should try to uninstall them and then check the device again.

When you save a problem, you need to do the following:

  • Enter the combination of numbers “##3646633##”, which allows you to get into the engineering menu.
  • Next, go to the Hardware section, where we open the Audio item.
  • We determine the mode in which there is no sound (this can be normal speech or speakerphone).
  • Next, click Headset Mode, where we go to the Type subsection.
  • It remains only to adjust the volume level for the Media, SPH and Ring parameters.

If all the proposed options do not help to eliminate the cause of the sound loss on the Xiaomi Mi 9 smartphone, then it is recommended to contact the service center specialists, since the solution to the problem will most likely require a full diagnostics of the device and the replacement of certain elements.

Why 4G does not work on Xiaomi Mi A1

High-speed 4G connection allows you to instantly access the Internet from your mobile device. Its absence significantly reduces the functionality of the gadget. There are several of the most common reasons why 4G (LTE) does not work on Xiaomi Mi A1, or it malfunctions. All of them, as well as ways to resolve them, are described in the article.

The main causes of the problem

High-speed Internet failures are expressed in the complete absence of a connection or its frequent interruption. Most often, the causes of such problems are:

Volume Issue Solved !! Xiaomi Mi A1 !!

  • Lack of the required amount on the account;
  • A failed SIM card, or an old-style SIM card;
  • Incorrect gadget settings;
  • Incorrect firmware (installed by the user from unofficial sources);
  • Mechanical damage.

It is possible to accurately determine the breakdown, due to which the Internet does not work on Xiaomi Mi A1, only by contacting a service center or a cellular company. At the same time, you can try to restore the correct functioning of the network yourself, before carrying out the diagnostic procedure.

The first attempts to restore the network

Before making serious attempts to restore the Internet connection, you need to make sure that the SIM card is functioning correctly and that there are funds on it. It is important that the SIM card is of a new type (micro, nano). Previous versions do not support high speed internet. If everything is in order with the money and the SIM card, you should proceed according to the following algorithm:

  • Set up connection: SIM card settings and mobile networks SIM settings Preferred network type. In this section, the Preferred 4G mode must be activated.
  • Contact your mobile operator. A remote communications representative will check the current status of your network and outline options for resuming normal operation.
  • Reset settings: General settings Reset data. This procedure will eliminate the possibility of system failure and errors.
  • Enter ##4636## on the phone keypad and activate the LTE Only mode. This method is considered a forced option to enable 4G.

If none of the above methods has been useful, there are two ways to solve the current situation: contacting the office of the mobile operator and providing the phone for service.

Cellular operator or service center

First of all, the phone must be provided to the company supplying the connection. Her employee will diagnose the device and identify any problems in the connection with the operator. The service center is the end point of the repair. You should contact its specialists only if even a communication representative could not restore the Internet.

What to do if the Xiaomi Mi A1 Internet is not working due to damage

Most often, self-configuring the gadget helps to cope with a broken 4G connection. But if this method is ineffective, do not ignore the need for diagnostics. Attempting to replace parts without first analyzing the device may result in additional malfunctions of the phone.

Why is the network not working on Xiaomi mi a1

No or low network signal is one of the most annoying smartphone problems. If the network does not work on Xiaomi mi a1, it is impossible to make calls, receive calls and send messages, and Internet access is available only using Wi-Fi. The problem can manifest itself both on one of the SIM cards, and on both. Most often, it occurs after a firmware update, when the network disappears immediately after the device is turned on.

The reasons for the lack of a signal can be software, for example, when IMEI flies after flashing, or hardware: the phone falls, moisture gets into it, careless removal of the SIM card. When this happens:

  • damage to the antenna or its contacts;
  • damage to the coaxial cable or its exit from the socket on the board;
  • failure of the SIM card reader as a result of bending the contacts;
  • failure of the high-frequency amplifier (UHF).

Diagnosing network problems on Xiaomi Mi A1

To understand what exactly is the reason for the lack of a network, you need to check for the presence of an IMEI code. To do this, dial #06# on your smartphone. If zeros are displayed instead of the code, you need to restore the IMEI. If everything is in order with the code, the problem should be looked for further.

Antenna damage can be detected by trying to make an emergency call to 112. If there is no signal even in this case, the antenna should be replaced. You can also test your smartphone on the Spectra analyzer by contacting the service center. This will allow you to check the frequencies on which the UHF transmitter operates and diagnose problems with it.

What to do if the network does not work on Xiaomi Mi A1

The simplest actions an owner can take to restore the signal are:

  • installing a new SIM card with 4G support;
  • factory reset with preliminary transfer of the necessary data to external media;
  • IMEI code recovery;
  • reinstalling the operating system.

Problema de Audio Xiaomi mi A1 solucionado

You can reflash the phone yourself by downloading the latest OS version from the official website of the manufacturer, or by contacting a service center, where it will take no more than 15 minutes.

If the previous procedures did not work, the master will disassemble the phone and determine which part is damaged. Depending on the location of the damage, it may be necessary to repair or replace the antenna, the entire GSM module, the coaxial cable, the UHF transmitter, the SIM reader, or the board.

In our GadgetParts online store, you can find the right spare part for Xiaomi repair at a lower price than in the service center. The catalog contains original components, as well as certified analogues identical to them with a guarantee. Due to prompt delivery, network operation can be restored the very next day after the order.

If you are also facing the issue where Wi-Fi is not working correctly, then our guide will give you a working solution.

Then restart your router and check if the problem is gone.

In case of failure, we continue to search for a solution.

  • Make sure your Wi-Fi connection is working. Take another phone and connect it to the Wi-Fi network. See if the device works on it. If everything is in order, then the problem is with your router or connection.
  • Make sure the signal strength is good enough (at least three vertical mowing lines) in the place where you are trying to connect Xiaomi Mi A1 to Wi-Fi.
  • Remember, you may have recently changed the WI-FI password from the router.

Password reset

Very often, to solve Wi-Fi problems, resetting the security password to connect to the network helps. To do this, just delete information about the current WLAN network and reconnect by duplicating the security key.

Smart Wi-Fi Switch (switch)

Perhaps, in the smartphone settings, the default selection is “Smart Wi-Fi Switch”. If this option is enabled, then the smartphone will constantly look for better alternatives to the current Wi-Fi connection and try to connect to a new network.

It is enough to turn off the smart switching option in the “Wi-Fi” settings (icon in the upper right corner).

Make sure Wi-Fi is always on

Some Android firmwares have a feature that automatically turns off Wi-Fi to increase battery life and conserve battery life if it is not used for a certain period of time.

On Xiaomi Mi A1, go to the “Wi-Fi” settings, look for the “Advanced” tab and select “Always” in the pop-up menu.

Hello dear friends! My name is Mikhail Xiaominko, I am a fan of Xiaomi technology, gadgets and smartphones. Having access to information, I try to provide interesting and high-quality content for Xiaomi readers. Sharing the latest news and exclusive content.

No sound on phone

As practice shows, the most common reason that the sound on the phone has disappeared is a change in the settings. It’s possible that you just accidentally turned down or turned off the sound, and therefore your phone stopped informing you about calls through audio effects.

Go to the sound settings and set the volume level to maximum. Then test the speaker. If everything is in order, and the sound appeared, then you panicked in vain and now you can continue to use your device calmly. If there are no changes, we advise you to continue checking the device to determine the cause of the breakdown. In the event that you cannot determine the cause yourself, contact an electronic device repair specialist.

MI A1 Audio issue fix

Distorted sound on phone

Often the sound does not disappear completely, but is simply distorted. It could be the speakers getting dirty over time. And to clean them, it is not at all necessary to carry the device to a service center. You can do this at home as well. We will tell you how to clean the speakers on your phone and improve the sound quality.

During operation, dust, dirt and small debris get on the fine mesh of the speakers. A layer is formed that prevents the normal reproduction of sound signals. Cleaning will help here. To do this, you will need alcohol and a toothbrush. Soak it in a small amount of alcohol and gently rub the surface of the speakers. All the dirt should go to the bristles.

A very fine needle may also help. With its help, you can push through the dirt and free the mesh holes. Just do not forget that you need to do this very carefully so as not to damage the speaker itself.

Clean speaker and microphone

Also check if the sound works in the headphones. If so, then it really is a matter of dynamics. In the event that the sound is perfectly reproduced through the speakers, but is not heard in the headphones, the matter may be in the breakdown of the 3.5 mini jack input. With such a malfunction, it is better for you to contact the service center. This part may need to be replaced.

In some devices, the sound does not completely disappear, but begins to be reproduced with wheezing and noises. After studying many different forums, we came to the conclusion that it is necessary to replace the back cover if the speaker in the phone wheezes. You can also try expanding the hole for the speaker. The aesthetic appearance may deteriorate, but the sound should improve.

Some users are experiencing audio playback issues while watching videos. The reason may be the lack of the necessary codec on the device. Install MXPlayer, this program will recognize which codec is needed and download it from the network and you can watch a movie with sound.

Troubleshooting audio problems on your phone

Users of mobile gadgets often face problems with sound degradation on their devices. RosKase will talk about the main problems and advise what to do in a given situation.

Missing sound on incoming calls

The essence of the failure is that a call comes in, there is a vibration, but there is no sound. First you need to determine what caused the failure:

The reason was found out, it’s time to talk about the solution to the problem. In the event that you downloaded and installed any application for playing music or for incoming calls, for example, a player, then most likely the program provoked a reset of the default settings.

To fix the situation, you need to enter the following code “##3646633##”, then go to “Hardware” and “Audio”. We select a mode in which there is no sound (speakerphone or normal speech). After that, click on “Headset Mode” and select “Type”. We adjust the appropriate volume level for the following parameters “Ring”, “Media”, “SPH”.

But it is always better to contact the service center, where a complete diagnosis of problems will be carried out and the best solution for repairing and restoring sound will be offered.

Redmi 7

The last smartphone we will talk about is Redmi 7. It does not have any particular problems. But very often the sound initially wheezes, and only after that it completely disappears. The only solution is to replace the speaker. But you should only contact a reliable service center to install a high-quality speaker there.

As with other devices, software failures can also occur, which you can solve on your own. Rebooting and resetting the device almost always helps. Sound recovery firmware is only made if you are completely sure that you can handle it yourself.

Redmi 8

You have lost sound on your Redmi 8 phone, but you do not know if it is a software or hardware problem? It is very easy to check this. If initially the sound only distorts, wheezes, makes other noise, and then turns off, then the problem is in the dynamics. In this case, only the replacement of this part in the service center will help.

But if the sound disappeared on the Xiaomi Redmi phone for another reason, then it might be worth doing all the same steps that we described earlier. Just restart your smartphone, reset the settings and clean it from dust.

Any other mechanical damage requires a mandatory visit to the service center, where employees can identify the real cause of the problem. This is due to the fact that on this smartphone, the sound may disappear due to damage to the speaker antenna or its oxidation when moisture gets in.

We summarize. the path to the service or self-repair?

Each problem is individual, and solve it in accordance with the reasons that led to it. Lost sound on Xiaomi phone and reboot and reset does not help? Path to service.

What to do if the sound on the phone is gone

Additionally, consider a more reliable way to check the performance of the speakers. Using it will tell you exactly if any speaker needs repair or if the actual problem is due solely to incorrect phone settings. To make sure that the Xiaomi speaker is not working, you should follow these steps:

  • Go to the engineering menu of the smartphone. To do this, in the call menu, dial the combination ##3646633##or##6484##.
  • Select the menu “Simulation Call Test” and, taking the phone in the position as when talking, say a few phrases. If you hear your own voice in the speaker, then be sure that the Xiaomi conversational speaker definitely works.
  • Select the “Speaker PA Calibration Test” menu. If the phone starts hissing or making other sounds, then everything is in order with the polyphonic speaker.

The advantages of checking through the engineering menu are that the test results do not depend on the phone settings. If no problems were identified in the test mode, then to resume the correct operation of the speaker, you only need to correctly configure the smartphone.

If there is no desired result after self-configuration, use the recommendations given in the next section of our article. If they do not help, then, as an option, reset Xiaomi settings by first saving the necessary files and other data on external media.

If the test performed shows a malfunction of one of the speakers, then there are two options. replace the Xiaomi speaker or try to repair it. We will definitely talk about these decisions today as well.

Missing sound on incoming calls

The essence of the failure is that a call comes in, there is a vibration, but there is no sound. First you need to determine what caused the failure:

The reason was found out, it’s time to talk about the solution to the problem. In the event that you downloaded and installed any application for playing music or for incoming calls, for example, a player, then most likely the program provoked a reset of the default settings.

To fix the situation, you need to enter the following code “##3646633##”, then go to “Hardware” and “Audio”. We select a mode in which there is no sound (speakerphone or normal speech). After that, click on “Headset Mode” and select “Type”. We adjust the appropriate volume level for the following parameters “Ring”, “Media”, “SPH”.

Open the application, go to the “Media|Audio” section, and select “Speaker”. A new window will open, in which you should select the “Phone Call Audio” command. Wait until the program completes its work, after that you can safely test. Sound will appear.

In some situations, there is no sound for incoming calls due to damage to the speaker antenna, and it can also oxidize due to moisture. In this case, disassemble the mobile phone, clean the speaker and fix the antenna.

Sometimes dust builds up in the audio jack, causing a short circuit. As a result, the smartphone shows a headset connection indicator on the screen, of course, it is not connected, and there is no sound. In this case, just clean the socket without turning off the mobile phone.

In general, the reasons for the non-working state of the lower speaker are the same as those of the upper counterpart. Troubleshooting methods are also the same. Therefore, if the phone does not play sound when you start video, music, and when you receive incoming calls, then it is advisable to follow the previously listed recommendations, and if they did not help, try to disassemble the phone and clean or replace the Xiaomi speaker internally. Although before disassembling, for starters, you should try to thoroughly clean the Xiaomi speaker from the outside. There is a chance that this method will return the speaker to working condition.

Also note that the lack of sound is sometimes associated not with a malfunction of the speaker, but with damage to other elements of the phone. As an example, here is a video that shows the process of disassembling a smartphone in order to fix the speaker. But the problem turned out not to be a malfunction of the speaker, but a breakdown of the nearby board. Details on the video.

Self check for physical damage

Before looking for problems in applications and OS, it is recommended to check the sound device itself. It may not function due to debris, water drops that have fallen into the MK hole. If the gadget falls, the microphone wire may come off or move.

To make sure that the audio device is correctly positioned and working, you need to run the hidden functions of the phone.

To open the desired tab, use 2 methods:

  • in the “Settings” menu, launch the “About device” window, and then click on the “Kernel version” item 5 times and turn on the inscription “Single Item Test”;
  • the same tab is opened from the keyboard with 2 different combinations ##4636## or ##6484##.

After that, they select the ring testing of the MK by clicking on the “Microphone” section, insert the headset and say something into it. The gain of the audio device is displayed on the screen, and a voice is heard in the headphones.

A negative test result indicates that the phone is mechanically damaged. Below is how to fix it yourself.

In some modern models, you need to find the MK launch test, it is called and passes in different ways. For example, in Mi 9 SE it is Main MIC, and in Xiaomi Mi 5 Main MIC Speaker Feedback Test.

When entering the menu, the user sees a volume scale with an arrow. On the 9th model, it is enough to put it on the table and say the phrase.

In Xiaomi Mi 5, the test is different. The smartphone should be put to the ear and say any phrase.

SD Card Issues

The SD card is the main storage for all data on the phone. With the constant operation of the mobile device, there is a stable filling with various files, including the application cache.

If there is not enough space left on the card, then the phone malfunctions, such as freezing or disabling any functions. This may cut off the soundtrack.

Therefore, you can try to clear the card of garbage or install an SD with a large volume.

There are also situations when the SD card fails due to the completed resource. If the condition is met that the breakdown occurred while the phone was working, the functionality may loop, which leads to audio playback errors.

In this case, you need to restart the device. Purely theoretically, performance should be restored.

After connecting the headset, the system automatically redirects all alerts to the headphone speakers.

There are cases when a system glitch occurs and the device gets stuck in a borderline state. That is, the headset is pulled out, but the sound is not restored.

Here you need to do the following:

  • Reconnect the headphones to the phone jack and immediately pull it out. After that, we try to change the volume, and for a complete check, run the audio file.
  • If the previous paragraph left everything unchanged, you need to connect heavy artillery and reboot the device.

With a probability of 99%, the sound should be restored, and the smartphone will return to our reality. If not, then you need to look for the cause elsewhere.

If sound is lost on Xiaomi or Redmi, it is necessary to exclude physical damage

Two things usually break: the speaker and the motherboard. We will not be able to check the motherboard, for this you need to completely disassemble the smartphone, and additionally you need special equipment and, most importantly, knowledge.

Therefore, we turn to checking the performance of the speaker.

To do this, we need to get into the engineering menu. Don’t worry, there’s nothing wrong with that, this menu was created specifically for quick but reliable testing of all major Xiaomi components.

To get into it, open the Xiaomi general settings, find the “About phone” menu. Now we need the line “Kernel version”. in MIUI 12, it hides inside the All Options menu. Click on the version 8 times in a row, and you will automatically find yourself in the engineering menu. Now look for the line “Speaker”. The test will start, unfortunately, I cannot say with high accuracy how it will look, because how it works and is called depends on the model to model, and the MIUI version. In my case, on the Mi 9 SE phone with firmware 12.0.3.0, the test looks like this: after entering the “Speaker” menu, the maximum speaker volume is automatically set and the female voice starts pronouncing two numbers in English. If you hear them, it means that the speaker is physically healthy, and you need to look for why the sound on Xiaomi has disappeared in a different plane. For the test to be considered passed, you need to click on the numbers that say the voice, but this is not so important for us.
