Overview of iPhone Screen Flickering

As earlier mentioned, insufficient memory is one of the major causes of iPhone screen flickering. When your iPhone doesn’t have enough storage, it starts to have performance issues like screen flickering, unresponsive display, and apps crashing or slow response.

iPhone screen flickering can also happen due to app incompatibility issues. Typically, if your iPhone screen only flickers when you try to open a specific app, the problem is with the app and not the iPhone. In this case, try uninstalling and then reinstalling the app. Hopefully, this will stop the screen flicker.

If the iPhone screen flicker does not result from insufficient storage or an incompatible app, it could result from a software update issue or the iPhone’s display system problem. This article delves into multiple solutions you can use to fix your iPhone screen flickering problem.
