What to do if the screen on your device is flickering

If the screen on your device is flickering, there are a few steps you can follow to find out whether the issue is software or hardware-related. Flickering is usually caused by a software issue which can be caused by glitches in apps or software bugs.

 

To best protect your device, make sure to update the software so that it is running the latest operating system and has the latest security updates installed.

Clear the cacheClick to Expand

Corrupted data in the system on your device can sometimes cause the screen to flicker. Clear the cache on your device, then check if the flickering continues.

Reboot in Safe ModeClick to Expand

If the problem persists, restart your device in Safe mode.

 

If the flickering stops when you are running your device in Safe mode, it could mean that the issue is being caused by a bug with one of the apps that you have downloaded. Find out which app is causing the problem and uninstall it. Start by uninstalling the most recent app you downloaded before the problem started. Repeat until the flickering stops.

 

If the flickering persists even in Safe mode, it is likely the issue is hardware rather than software-related. If this is the case, contact your nearest Service Centre.

If none of the solutions above fixes the issue, please contact your nearest Service Centre.
