How To Fix Huawei Nova 3 Screen Flickering Issue

Before performing any of the recommended troubleshooting steps for this issue it’s best to make sure that your phone is running on the latest software version. If an update is available then I suggest that you download and install it first. Once the software has been updated proceed with the troubleshooting steps listed below.

The most common reason as to why the screen of the phone will flicker is due to a software glitch which is why we will be concentrating our troubleshooting efforts on the software side of the device. Follow the troubleshooting steps listed below to fix the problem.

Perform a soft reset

What you will want to do first is to refresh the phone software. This can be done easily by simply restarting the device. Although this is usually performed when the device is unresponsive it is also recommended in this case as refreshing the phone software 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

Sometimes an app you downloaded from the Google Play Store will cause the Huawei Nova 3 screen flickering issue when it is installed. This can be due to bugs in the app or incompatibility issues between the app and the phone. 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

If 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.

To find 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 your phone.
  • Press and hold Volume UP button along with Power button on your  device simultaneously for a few seconds
  • The phone will enter the stock recovery mode
  • 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 Huawei Nova3 screen flickering problem then there is a possibility that this is caused by a system 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 your phone.
  • Press and hold Volume UP button along with Power button on your  device simultaneously for a few seconds
  • The phone will enter the stock recovery mode
  • Use volume buttons to highlight  select wipe cache/factory reset and use power key to select it
  • Reboot the system once the process is completed

Setup the phone, but do not install any apps yet, then check if the issue still occurs. If it does then this might already be caused by a faulty hardware component, possibly the display assembly. What you will want to do right now is to bring the phone to a service center and have it checked.
