Why do Android phones always display unread messages?

The problem may be related to the software.

1. Check whether the mobile phone has recently downloaded third-party software (battery management, security guards, system management). It is possible that the software is not compatible with the mobile phone, which makes the mobile phone unable to lock the screen. It is recommended to uninstall.

2. If it is not solved, it may be related to the system. You can restore the factory settings of your mobile phone by backing up its data (phone book, SMS information, multimedia materials, etc.). ).

3. If the problem has not been solved, it may be related to the mobile phone hardware. It is recommended to bring the purchase invoice, maintenance card and mobile phone to the local service center, and the engineer will test the mobile phone.

4. Turn off the reservationless activity in the developer option, and turn off the reservationless activity in the application-settings-developer option (some model developer options are hidden).

5. This may be caused by wrong information data. Click Application-Settings-(More/General)-Application Manager-All-Information-Clear Data.

6. Please update the mobile phone software to the latest version, and apply-Settings-My Device-System Update (pay attention to backup the important data of the mobile phone).

7. If not, please back up the phone data and restore the factory settings (Settings-Reset/Privacy-Restore the factory settings).
