Turn Your iPhone Off and On Again

It might seem like a joke at this point, but there’s a reason why turning off and back on your iPhone is still a pretty common piece of advice: it works.

Restarting your iPhone will not fix every issue, but it can help resolve many problems with your iPhone or other devices, including a flickering screen.

How you restart your iPhone will depend on which model you have. For iPhones with Face ID, you’ll need to press and hold one of the volume buttons and the side button until the power off slider pops up.

For iPhones with Touch ID, you only need to press and hold the side button until the power-off slider appears.

Drag the slider to the right to turn your iPhone off, and then leave it off for about 30 seconds. Afterward, regardless of your iPhone model, press and hold the side button until you see the Apple logo on your screen.

As we mentioned, this method can solve many issues, so start using your iPhone again and see if this fixes the problem.
