Troubleshooting Galaxy S10 Plus screen flickering issue

A flickering screen can be just due to a minor software-related problem but if the phone has been dropped or got submerged in water for a very long time, then it is almost certain that it’s a hardware-related problem. So, before you begin troubleshooting, make sure that it’s not due to physical or liquid damage. If it’s not, then follow these steps to troubleshoot your device.

First step: Run your phone in Safe Mode

The purpose being is that you will have to observe the device to see if the flickering still happens in this mode. Assuming that the flickering disappeared, it means that the problem is caused by a third-party app. Look for such app and try resetting it by clearing its cache and data. If the problem is still not fixed, then you may have to uninstall it. Resetting and uninstall the app is the easy part, determining which app causes the problem is the most challenging part. But when it comes to screen issues, it more often a heavy game app that’s causing it. So, if you’ve been playing intensively, you already know which of your games is causing the problem.

On the other hand, if the problem still occurs even in safe mode, then you will have to continue troubleshooting as the problem could be with the firmware.

Now, here’s how you start your phone in Safe Mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the 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. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

In this mode, all third-party apps and services are temporarily disabled that’s why it’s logical to do this procedure before anything else to rule out the possibility that the problem is caused by one of your apps or games.

Second step: Wipe cache partition

Let’s go straight to troubleshooting the firmware and the next thing you should do after the safe mode remedy is to wipe the cache partition. This will delete and replace the system cache. It’s very important to do this procedure because a corrupt cache may cause a lot of issues to your phone’s overall performance.

To do this procedure, you will have to run your phone in recovery mode and wipe the cache directory from there. None of your files and data will be deleted so there’s no need to worry about backup. Here’s how it’s done:

  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 Android logo displays, release all three keys.
  4. An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.
  9. Press the Power key to restart the device.

Your phone will take a little time rebooting after this procedure as it will rebuild the cache that has been deleted. After that, try to see if the flickering continues and if so, then you have no other option but to reset your phone.

Third step: Backup files and reset phone

At this point, it’s important that you perform the master reset even if there’s no guarantee that it will fix the problem. Not only does it rule out the possibility that it’s a firmware issue, it will also delete all your personal information, files, apps and many more. So, if the problem continues after that, you don’t have to worry about your privacy if you decide to bring it back to the store and have the technician take a look at it.

Therefore, make sure to backup your important files and data before the reset as they will be deleted and you may no longer be able to retrieve them after that. Also, make sure that you know the password of the Google ID that’s setup on your phone because you will have to use the same account to set up your phone after the reset. Better yet, just remove the account before you actually reset the device.

  1. Back up data on the internal memory. If you have signed into a Samsung account on the device, you have activated Anti-theft and will need your Samsung credentials to finish the master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. 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).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

If all else fails, then you have to take a trip back to the store and have the phone checked. It’s very much possible that it’s a hardware problem.
