The iPad screen flickers on and off after using it for a period of time? Never mind. Here are some proven solutions.
1. Check if the iPad screen just flickers in a certain app. You just double-click the "Home" button to open the app switcher. Then find a certain app and swipe it away. After the operation, you can launch this app again to see if the screen still flickers.
2. Hard reset the iPad.
For iPad with "Home" button: firstly, you just press and hold the "Home" and "Power" buttons. Then, don't release them until the Apple logo appears on the iPad screen;
For iPad without "Home" button: you can press the "Volume Up" button and release it quickly firstly. Next, press the "Volume Down" button and release it. And then press and hold the "Sleep/Wake" button until the iPad begins restarting.
3. Turn off Auto-Brightness. Go to Settings > Accessibility > Display Accommodations > Auto-Brightness.
4. Reduce Motion and Transparency. Head to Settings > General > Accessibility > Increase Contrast > Reduce Transparency. And then return to the "Accessibility" option and move the slider ahead of the "Reduce Motion" to enable it.
