How to Fix Screen Flickering on Android

Diagnosing and repairing a flickering smartphone display

Screen flickering can happen on Android smartphones for several reasons. Most of the time, it’s easily fixable, but sometimes it calls for hardware repair or even replacement. This article will outline how to troubleshoot and fix a flickering screen on an Android phone.

Causes of Screen Flickering on Android

A flickering or flashing screen has many potential causes, including software glitches or problems with settings.

Physical damage can also be the culprit, such as:

  • Water damage
  • Dropped phone
  • Power source or charging cable issues

How Do I Stop My Screen From Flickering?

If you know the cause, it’s easy to figure out what to do—but it’s not always obvious. Start with the simplest solution and move on to more complicated ones until you resolve the problem.

  1. Restart your Android phone. Often the fastest way to solving a problem is to restart your device. Try this first.

  2. Update the OS on your Android phone. Check for an update. Sometimes an update introduces a bug, and the company later issues a fix. Make sure your Android is up to date.

  3. Update the apps on your Android. Is the screen flickering only in a specific app? See if it needs an update. And while you’re at it, make sure all your other apps are updated.

  4. Check brightness settings. Go to Settings > Display > Adaptive brightness and toggle it off. The screen flickering could be due to this setting interacting with your lighting situation.

  5. Disable any blue light filter apps you have installed. These apps can help with eye strain and even help you get to sleep, but they could also be the cause of your phone’s screen glitches.

  6. Disable Night Light or blue light filter settings. Android’s Night Light setting or Samsung’s Blue Light filter could trigger screen flickering.

  7. Clear the cache on your Android phone. Clearing the cache can solve many problems, including display issues.

  8. Turn off Developer options. Go to Settings > System > Developer options and switch the toggle off (if it’s not already). It’s possible you or another user turned on something that’s messing with your screen. The easiest fix is to disable these options altogether. 

  9. Run your Android smartphone in Safe Mode. Reboot in safe mode. If the screen still flickers, then you’re likely dealing with physical damage.

  10. Inspect your smartphone for physical damage. Contact the store you purchased it from, your mobile carrier, or go to the manufacturer’s support website. There are some more tips on Google’s support site.

  11. Try a factory data reset. If you don’t see apparent damage and none of the other steps have worked, a hard reset might do the trick.

  12. Contact tech support if nothing else works, or you suspect your phone might have physical damage.
