2. Charge Your Device:

4. Boot into Safe Mode:

  • Press and hold the Power button until the Power off option appears on the screen.
  • Press and hold the Power off option until Safe mode appears, then tap it to boot into Safe mode.
  • If the screen works in Safe mode, an app may be causing the issue. Try uninstalling recently installed apps to see if the problem resolves.
