iPhone apps keep flickering? Here’s a solution!

Sometimes, you may find your iPhone apps flashing on and off and have no idea why it is happening. In such cases, the screen will flash, change colors rapidly, or go black. Most of such issues have something to do with hardware damage.

However, you may experience flickering apps on a new device that has no damage at all. In this case, you can easily solve the issue as this post is going to guide you below.

Why do apps flicker on my iPhone?

You may experience iPhone app blinking or flickering due to one of the following reasons:

  • Your iPhone running low on memory
  • Broken hardware components especially in the display circuit mostly caused by water damage or dropping
  • Bugs in the iPhone’s software

To deal with the flickering issue, you can employ several different approaches. These approaches include hard resetting, toggling brightness level, reducing transparency, and cleaning memory.


You can solve the flickering by a simple reboot of your iPhone. To do this, hold won the Home and Power buttons simultaneously until the Apple logo shows on the screen. While at it, ensure that you battery is in good working condition as this may also contribute to the flickering issue.

High brightness settings may play a role in the flickering of your iPhone. For troubleshooting purposes, set brightness to the lowest level and disable Auto Brightness. Give it about 15 minutes before returning it to the initial state. Doing so should help in managing the flickering problem.

As a temporary solution, you can enable the Reduce Transparency feature. To do this, you must go to Settings >General>Accessibility and then tap on Increase Contrast. At this point, toggle the Reduce Transparency switch to on. Clear all unnecessary files to free up some memory too and see if it helps the problem go away. Also, ensure you are running the latest iOS version to eliminate the chances of software bugs being the cause of the problem.

If the problem persists after trying all the above troubleshooting methods, the flickering may be due to hardware damage. Go to the nearest Apple store if your warranty is still valid to get the issue fixed. Otherwise, you may have to pay an extra fee to have a qualified professional clean out and replace your iPhone’s display if necessary. Also, you can do it yourself if you are familiar with tearing down iPhones.
