Iphone 1 1 has voice shadow on the screen.

There may be some faults in the operation of the mobile phone.

Possible scenarios and solutions are as follows:

1, in most cases it is not a screen card but a mobile phone system card. You can restart your phone or wait. Try not to run too many programs.

2. There is water on the screen. Capacitor screens with water will fail.

3. Static electricity. Sometimes rubbing clothes on the screen of a mobile phone will break down. Just to eliminate static electricity.

4. There may be something wrong with the screen. Go to the maintenance point to check.

5, or you may brush another ROM.
