How to remove the top of Samsung mobile phone

Through the description, it is suggested that:

1. Restart the machine and try.

2. After uninstalling the recently installed third-party software, observe whether it is a software conflict, such as mobile phone housekeeper, games and other software.

3. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter phone settings-reset-restore factory settings).

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.
