Investigation and solution of Samsung mobile phone problems

Dear Samsung users: Through your description, I suggest you.

Restart the machine.

I suggest you turn on the machine again and try to solve this problem.

Replace screen wallpaper

It is recommended that you change the screen wallpaper, excluding whether to set the desktop screenshot as wallpaper.

Back up data and restore factory settings.

It is recommended that you back up your mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings (enter phone settings-reset/privacy/private-restore factory settings).

Samsung service center detection

If the problem of restoring factory settings still exists, it is recommended to send the mobile phone to the nearest Samsung service center for testing and further processing. Please visit:
