How To Fix Huawei P20 Lite Screen Flickering Issue

Whenever your phone screen flickers the most likely factor that is causing this problem is a software glitch. You might have downloaded an app that makes the screen flicker or there might be some corrupt data in the phone that’s causing this behavior. Listed below are the recommended troubleshooting steps you need to do to fix this problem.

Perform a soft reset


The first thing you will want to do is to refresh the phone software which can be done easily by simply restarting the device. Refreshing the phone will usually eliminate any temporary corrupt data that could be causing the problem.

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Check if the issue still occurs.

Start the phone in Safe Mode

There are cases when an app you downloaded will cause issues on the phone when they are installed. To check if an app you downloaded is causing the problem you will have to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • Power off the phone by holding down the power button for a few seconds.
  • Press and hold the power button and release it when you see the Huawei logo on screen.
  • After releasing the Power key, immediately press and hold the Volume down key.
  • Keep holding the Volume key till the phone completely boots up.
  • Once the phone boots up,  “Safe mode” should be appeared on the bottom of the screen

In case the issue does not occur in this mode then it is most likely caused by an app you installed. Find out what app this is and uninstall it.

As for finding the specific app you will need to do a trial and error method. Start by uninstalling the last app you downloaded before the issue occured. If the problem still occurs then uninstall the next app on the list. Once the screen stops to flicker after uninstalling a specific app then that app is the most likely culprit.

Wipe the cache partition of the phone

There are cases when the cached data stored in the dedicated partition of the phone can become corrupted. When this happens this this will usually cause certain issues to occur on the phone. To eliminate the possibility that this is what’s causing the problem you will have to wipe the cache partition of the phone from the recovery mode.

  • Turn off the device.
  • Press and hold the Volume Up button.
  • While holding the Volume Up button, connect USB charger to the phone.
  • Within a few seconds, your phone will boot into the recovery mode.
  • Now, remove the USB charger.
  • Use volume buttons to highlight ‘wipe cache partition’ and use power key to select it
  • Reboot the system once the process is completed

Check if the issue still occurs.

Perform a factory reset

In case the above steps fails to fix the problem then chances are this is caused by a software glitch. The best way to deal with this right now is to perform a factory reset. Make sure to backup your phone data before doing the reset.

  • Turn off the device.
  • Press and hold the Volume Up button.
  • While holding the Volume Up button, connect USB charger to the phone.

  • Now, remove the USB charger.
