How to fix Galaxy Tab S5e screen flickering issue

Are you having Galaxy Tab S5e screen flickering issue? This troubleshooting guide should help. Follow the solutions below and see what happens.

Galaxy Tab S5e screen flickering solution #1: Check for hardware damage

The screen on your Galaxy Tablet is one of the reliable parts. That’s the case unless drop the device or hit it with something really hard. You are the owner of your phone so you have firsthand knowledge of its history. If your Galaxy Tab S5e screen flickering issue started after the device has been dropped, hit by something, or even exposed to water, don’t waste time looking for software solutions. If any of those things happened, you can assume bad hardware is the reason. What you have to do is to have the device checked by a professional, preferably by a Samsung technician, so proper troubleshooting can be performed. For example, if the phone has been dropped and there’s visible crack on the screen, there’s no amount of software troubleshooting that you can do to fix it. The least that can be done is to replace the screen. If it ever comes to that, be sure that you let a qualified technician do the task for you. Unless you’re confident that you can do screen replacement without damaging other components, do-it-yourself screen repair almost always fail for amateurs. There may DIY videos that you can follow but doing the exact thing for the first time may be harder than you think.

Galaxy Tab S5e screen flickering solution #2: Perform soft reset

If there’s no obvious reason to suspect that bad hardware is to blame, your Galaxy Tab S5e screen flickering issue may be caused by a temporary software bug. Minor problems caused by temporary bugs usually go away after restarting a device. If you haven’t tried it yet be sure to do so.

In restarting, we suggest that you simulate the effects of a “battery pull” rather than do a usual restart. This will ensure that the device is refreshed and its RAM cleared. To do that, simply press and hold the Power and Volume Down buttons for about 10 seconds. Once the phone has restarted, release the buttons. This is usually effective in clearing bugs that developed when a system is left running for some time. We suggest that you restart your A80 using this method at least once a week to lessen the chances of bugs.

For some Galaxy M30, there may be a slightly different way to arrive at the same method. Here’s how:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. Note: Utilize the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Also, allow up to 90 seconds for the reset to complete.

Galaxy Tab S5e screen flickering solution #3: Toggle Adaptive Brightness

The latest Samsung Galaxy devices have the Adaptive Brightness feature that is enabled by default. This feature automatically adjusts screen brightness depending on your environment’s light intensity. Your phone’s screen should be lit brighter when you’re outside and ambient light is strong. The opposite occurs when you’re in a dark room. While this feature works fine most of the time, it may not work properly if there’s a bug somewhere in the system. We’ve seen this phenomenon with older Galaxy devices and Samsung did not actually provide a specific explanation why it occurs. One of the signs that Adaptive Brightness bug is present is screen flickering. Try to toggle off Adaptive Brightness and see what happens. Here’s how:

  1. Open Settings app.
  2. Tap Display.
  3. Turn off Adaptive Brightness by moving the switch to the left.
  4. Check for the problem.

Galaxy Tab S5e screen flickering solution #4: Refresh system cache

In order to load apps quickly, Android stores frequently used items like website links, images, videos, ads, among others in a part in internal storage called cache partition. Sometimes, these items collectively called system cache may get outdated or corrupted causing performance problems or bugs. To ensure that you phone runs efficiently and the cache in top shape, you want to regularly clear the cache partition (about once every few months). To check if there’s a problem with the system cache, follow these steps to clear the cache partition:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Galaxy Tab S5e screen flickering solution #5: Check for bad app

Sometimes, a bad third party app may affect other apps or the Operating System. If Galaxy Tab S5e screen flickering issue happened after you install a new app or game, that can be the reason. Try to delete it and see how it goes. If you can’t recall the app, try to restart the device to safe mode instead. This will force the phone to only load pre-installed apps. The rest of the apps that are not part of the original OS will be blocked. To boot to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

While your Galaxy Tab S5e is on Safe Mode, all of the apps you downloaded will be suspended; only preinstalled apps will be allowed to run. So, if your messaging app works normally and MMS can be sent without issues, that’s a clear indicator of a bad third party app problem. To identify which of your apps is the source of trouble, you must use elimination method. Here’s what you can do:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Galaxy Tab S5e is still problematic, repeat steps 1-4.

Galaxy Tab S5e screen flickering solution #6: Install updates

Some Android problems are due to poor coding. Although we don’t hear any flickering screen problem due to firmware glitch, it’s not a bad idea to keep Android and apps up-to-date. If you’re lucky and your unique case is due to an unknown software or app glitch, installing updates may help.

Galaxy Tab S5e screen flickering solution #7: Reset app preferences

Some apps require that a certain default or system app is working. To make sure that all default apps are up and running, you can reset app preferences with these steps:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your Galaxy S10 and check for the problem.

If you are positive that there’s no hardware damage at all and none of the solutions above has not worked, you should consider wiping the phone. If the cause is due to a software bug, factory reset will likely fix the problem. Before you do a factory reset, be sure to create a backup of your personal data.
