A flickering phone screen is one of the most annoying experiences you can face. The problem is common in both Android and iOS devices. And the causes vary.

You have to identify the cause of the issue before finding a way to fix it. Here, we will explain the causes and provide instructions for fixing the problem. The resolutions are pretty similar for both iPhones and Android devices.

What causes phone screen flashes in Android and iOS?

These are the main causes of a flashing screen on the phone:

Software glitches

Phone screen flashes are primarily caused by software glitches affecting your display. In simple cases, the flickering only lasts for seconds.

Games and media editing apps are mostly responsible since they push your phone’s graphic processing power to its limits.

If the flickering continues or appears more randomly, there is a different problem.

Physical damage

Physical damage to your screen will affect your phone’s display. If your iPhone screen is flashing like a strobe light, then it might have experienced some damage.

Check your device for any physical signs of damage to ascertain that it is not what is causing the faulty behavior.
