So, you should also try it once and check if the problem disappears. To do it, first, open Settings and then click on General -> Accessibility -> Display Accommodations. And here switch off the button next to Auto-brightness.

In this situation, you need to close the app first to fix the issue. For that, you have open app switcher on iPhone. For iPhone 8 and other models, double press Home button.

After opening app switcher, simply swipe up and off the screen to close your app. But if the problem still continues then you should uninstall the app immediately and again reinstall it or have to find other method.

To remove or delete an app from iPhone, simply press and hold the icon on Home screen and then click on small X that occurs. At last, click on Delete button to confirm.

  • First, go to Settings on your phone and tap on General tab
  • Then scroll to Accessibility tab and tap on it

  • Change the damaged LCD screen but advised not to do on your own.

Way 8: Do factory reset of iPhone

This is the last step that you should do to fix iPhone screen flickering and unresponsive issue. Doing this process not only will solve the issue but at the same time, there is a risk of losing all important data from phone.

So before going through this method, backup all your crucial data in safe place and then follow the below steps:
