Samsung Screen Does Not Work

Read more about the reasons why the screen does not work on the Samsung phone

We have already said above that the exact cause can be identified only with the help of diagnostics on the professional equipment of the service center. But, consider the main signs.

It is worth mentioning that under this breakdown, many smartphone owners often mean a non-working touchscreen, i.E. Touch screen. Describing a breakdown as a non-working display, it means that the screen does not respond to touches. We are considering cases when the display does not work, i.E. No picture.

Samsung phone display not working

If your Samsung phone doesn’t work with the display, there can be many reasons. Only professional diagnostics can tell for what reason a malfunction of this kind occurred.

So that you understand. Modern smartphones consist of many small components that are connected to each other using loops. Not only the component itself can be damaged, but also microfractures on the plumes can appear. In the case of moisture penetration under the case, especially for sweet or viscous drinks, oxidation can occur, which also causes unpredictable consequences.

The reasons

  • Physical damage. This category of causes includes not only shocks and falls, but also the ingress of liquids. There is not always visible damage on the screen surface. A microcrack in the board or one of the connecting components is enough for the screen to stop working. The influence of liquids was discussed earlier.
  • The display stopped working after updating the firmware. Here are the cases when the phone turns into a brick and does not fully respond, or there is an indication of switching on (diodes are on or there is a vibration response), but the screen still does not turn on. Probably the firmware is not suitable, or there was a failure during the update and the installation went wrong. In this situation, you will have to reflash the smartphone again.
  • The screen stops working while using the smartphone. Those. You are using your Samsung and at some point the screen goes blank. There is a high probability of failure of the proximity sensor, which is responsible for locking the screen during a call when you bring the phone to your ear.

We have listed all the reasons and cases of display failure in phones from Samsung and any other manufacturer. Most often, of course, the cause is physical injury.

Our advice: contact the service center. Trying to figure out the problem yourself, you can only harm and make the final repair more expensive.

How to forcibly turn off a Samsung smartphone

When you need to turn off your Android Samsung Galaxy phone in a normal situation, just press and hold the screen off button, and then select the desired item in the menu. However, the situation is complicated when you need to turn off a smartphone with an inoperative screen sensor, with a broken screen or without the ability to unlock it, a frozen phone, especially considering that batteries in modern Samsung are non-removable. Some in this case wait for a complete discharge, but this is not at all useful for the battery (see What to do if Android runs out of battery quickly). However, there is a way to shutdown in the described scenarios.

This short tutorial details how to force shutdown your Samsung Galaxy smartphone using only the hardware buttons on it. The method works for all modern models of smartphones of this brand, including a locked device with a completely non-working screen or in cases where the phone is frozen. Unfortunately, the reason for writing this article was my own brand new broken Note 9 (but there are some pluses: thanks to Samsung Dex, full access to memory, data in it and applications remained).

Turn off Samsung Galaxy with buttons

As promised, the instruction will be very short, a forced shutdown consists of three simple steps:

Connect your Samsung Galaxy to the charger.

  • Press and hold the power button and volume down button. If at this moment the creation of a screenshot occurs, do not pay attention, continue to hold the buttons.
  • Release the buttons after 8-10 seconds, the smartphone will be turned off.

By itself, the specified combination causes (after holding) a simulation of disconnecting the battery (Simulated Battery Disconnect in the official formulation of the manufacturer).

And a couple of notes that might be helpful:

  • For some older models, a simple long hold on the power button works.
  • The official Samsung website says about the need to hold the indicated buttons for 10-20 seconds. However, in my experience, it works around the 7-8th.

I hope the material was useful for some of the readers.

Phone display not working: types of breakdown

Many smartphone makers have removed the hardware interface to save on size, weight and cost. The result is a device that you can only interact with via a touchscreen.

Several scenarios for a non-working display can be described:

  • Small crack in the screen
  • Cracked screen, part of the screen not showing
  • Cracked screen, touchscreen not working
  • Crack with broken touchscreen and display problems
  • The screen is not cracked, but the sensor does not work

Each type of breakdown will affect the way you use your phone. However, none of these should render the device unusable.

A practical solution for a smartphone with broken display repair. However, some problems can prevent this: for example, lack of warranty or unavailability (high cost) of spare parts.

If you cannot fix your phone professionally, you can replace your damaged phone display.

Why Touch Phone Screen Doesn’t Work?

The touchscreen display on any phone can stop working for many reasons. Here are the most common problems that make your smartphone screen unresponsive to touch:

  • Physical damage resulting in damage to the touch screen. High temperature, cold, humidity, magnetism, or static electricity can damage the touchscreen on your Android phone.
  • Malware or performance-enhancing applications that affect the phone’s system in such a way that the sensor does not respond to touch. (Antivirus is recommended to avoid this)
  • Android system crash after firmware update, incorrect reboot, insufficient RAM or internal memory.
  • Incorrect settings.

A factory reset (resetting your phone to factory settings) will restore your phone to its default settings and fix most of the above issues. If the touchscreen just stops working for no clear reason, it is probably caused by a software issue. How to fix a touchscreen with physical damage later in the article.

Phone sensor does not respond to touch first aid guide device

Very often, the touch screen on a smartphone starts working incorrectly, incorrectly, or simply does not respond to pressing. As a rule, all problems in this case can be divided into 3 groups:

  • The touchscreen has stopped working on the smartphone and is completely unresponsive to any taps.
  • The touchscreen is not working properly: when you press a you get b.
  • Delay when clicking, braking, screen distortion, color change.

Let’s try to understand the reasons for such breakdowns and try to eliminate them without resorting to specialized service. No matter what model or brand of phone you are facing, this guide will help you solve almost any problem.

The smartphone screen does not respond to any touch what to do?

If the touchscreen has no physical damage but suddenly stops responding to your touch, it could be caused by a software problem. Here are the main and most effective ways to fix the problems that have arisen:

Before delving into any other troubleshooting procedures, restart your phone or tablet to fix software errors that might prevent your device from working.

Reboot any Android touchscreen device as follows:

Press and hold the power button until the screen turns black.

After 1 minute, press the power button again to turn on the device.

In many cases, the phone will respond normally to touch after rebooting.

Remove the memory card and SIM card

Sometimes a faulty memory card or SIM card is to blame. Hence:

  • Reboot your device and check if the problem is gone.
  • Put your device into safe mode

Corrupted or extraneous apps can also cause a touchscreen issue on your phone or tablet.

In safe mode, all downloaded third-party applications will be disabled, i.E. Only standard applications will be loaded, which are necessary for the operating system to work and maintain the minimum functionality. Therefore, if the display works well in safe mode, you should uninstall some applications, especially those that were installed very recently, before the touch screen problem.

  • Turn off your Android device.
  • Then long press the power button to reboot the device.
  • When you see the phone brand logo, release the power button, press and hold the volume down button.
  • Release the volume down button when the device boots up with the safe mode indicator in the lower left corner.

Attention! If your phone sensor is not responding to touch, lags behind, slows down or responds incorrectly, you can also try using this method.

When you see a message about restarting your device in safe mode, click OK. Safe Mode is enabled. If no problems are observed, start uninstalling third-party applications by periodically rebooting the device and checking the smartphone’s operation in normal mode.

  • Restore to factory settings

If the touchscreen is completely unresponsive, it may need to be restored to factory settings.

This procedure will erase all data on your device, including downloaded apps, photos, messages, contacts, etc. Without POSSIBILITY OF RECOVERY. Therefore, use this method as your last chance. Back up your Google account in advance.

The steps to enter recovery mode are different for many Android models. In other articles, we have already mentioned how to do this, so we will not repeat ourselves and proceed to the next method.

  • Calibrating the touch screen using the app

Type touch screen calibration in the Play Store search bar and the system will give you quite a few results.

Read the reviews carefully before downloading any of the applications, give preference to verified authors.

Physically damaged touchscreen: how to fix it?

If your phone or tablet has been hit, dropped, or otherwise damaged, the sensor will most likely stop working 90% of the time. Do not rush to run to the service center! Before replacing a new display, try these free tips first:

  • Preliminary diagnosis of damage

What to do if the touchscreen does not work after a fall? A diagnostic test won’t fix the problem, of course, but it does help determine which areas of the screen are really not responding. To access the diagnostic tool, you need to enter a specific USSD code in the dialing line of the phone number.

All codes differ for Android devices of different manufacturers, models, OS versions. Here are some tested codes that are commonly used (the. Symbol after the # symbol is NOT written):

# 7353 # most Android smartphones, especially Samsung;

# # 3424 # # for HTC;

# # 7378423 # # Sony Xperia series smartphones;

# 0 # Motorola and subsidiaries.

For example, here’s how the test is performed on a Samsung Galaxy S4, Android 4.0:

  • Open the phone dial.
  • Enter # 7353 # to enter the diagnostic tool menu.
  • Select TSP Dot Mode or TSP Grid Mode which are used for touch screen testing.

Tsp Dot Mode will show small dots when you tap on the screen, while TSP Grid Mode allows you to test every area of ​​the screen in a grid overlay. By using both of these modes, you can determine which part of the display is most affected.

  • Broken cable

If the device is dropped, the digitizer cable may be loose (detached) and the touchscreen may not respond. This can be fixed fairly easily by tapping lightly on each corner of the touchscreen several times. In 50% of cases, this method helps.

What to do if the sensor does not work on the Samsung a50 or does not respond well

First forced restart. This is important because it will refresh your phone’s memory. It is always possible that the problem is caused by a system crash or that some services have stopped working causing the touchscreen to stop responding.

To do this, press and hold the Volume Up and Power keys at the same time for 10 seconds or longer.

Your phone will start normally, but if the problem is really minor, then that should be enough and the touchscreen may work again.

Second security mode. You must enable safe mode if the problem persists after a forced restart how to do it is described here.

This will temporarily disable all third-party applications and will immediately inform you if the problem is caused by a third-party application or not.

If the touchscreen works fine in this mode, it means that a third-party application or service is calling it.

In this case, you need to move on to the next solution to fix the problem, but if the problem persists in this mode, skip uninstalling some applications and proceed to deleting the system cache.

Uninstall third party apps. The uninstallation of third party apps is triggered by the next step to be followed if your touchscreen is in Safe Mode.

It can be tricky, especially if you don’t know which app is causing the problem, but once you point it out, it will definitely fix the problem.

Third, clear the cache partition. To do this, you can boot the phone in recovery mode, but there is a simpler way, instructions here.

Caches are temporary files created by the system itself to keep your phone running smoothly and flawlessly, but they are prone to damage and when this happens, this is just one of the problems you may encounter.

Fourth factory reset. After following the previous procedures, the touchscreen is still unresponsive, you have no choice but to reset your phone to rule out the possibility that this is only a temporary software issue.

Please back up important files and data before resetting as they will be deleted, so please back up your data. Who does not know how to reset can find out here.

Fifth, take the phone to a service center. If all else fails, there may be a hardware problem, specifically the digitizer that is part of the display module.

It may already be damaged, or it may be a minor flex cable issue. However, this is a hardware problem and you need the help of an authorized technician to open your phone without losing your warranty.

I hope I was able to help you fix this with your device. Thanks a lot for reading! Success.

What to do sensor stopped working on samsung galaxy a50

Although Samsung Galaxy a50 phones have appeared quite recently (with the release of android 9), there have already been isolated cases that the sensor stopped working or if it works, then it is bad.

Let’s hope that if your sensor does not work, then the reason is not in the hardware, which can result from an impact when dropped, water ingress, exceeding the permissible temperatures, damage to the screen controller or a factory defect.

In such cases, you may need to replace the sensor on your samsung galaxy a 50, sensor controller, flex cable, connector, or cleaning from traces of corrosion.

Yes, sometimes these hardware components can stop working for some reason, but somehow I will share with you troubleshooting procedures that have proven to be effective in fixing problems when the sensor is not working.
