Why does the phone always ring suddenly? How to solve it?

If you use a vivo phone, you can try the following methods to troubleshoot:

1. Please clean up the background program. If the phone stops ringing after cleaning the program, it is a software-triggered ringing.

Please restart your phone to see if it is restored. Software anomalies may cause the phone to ring all the time.

3. If the third-party housekeeper software is installed, it is recommended to observe after uninstalling.

4. Enter Settings-System Management/More Settings-Backup and Reset/Restore Factory Settings-Restore All Settings-Restore.

Note: Restoring all settings will not delete any data or media files, but only restore all settings of the mobile phone (such as setting wallpaper, unlocking method, WiFi, default startup program, desktop layout, etc.). ), some third-party application accounts need to log in again. Please ensure that the use of the software will not be affected before operation. For the sake of data security, it is recommended to back up the mobile phone data in advance before operation. (You can go to Cloud Service-Device Cloud Backup-Backup Data Type-System Data-Back-Back up some backup system settings and desktop layout immediately; Cloud service-data synchronization-enable WLAN, Bluetooth, etc. Synchronize data to cloud services)

5. If the above methods can't be solved, please back up the mobile phone data in advance, and take the mobile phone and purchase certificate to vivo customer service center for testing.

Tips: It is suggested to call the staff of the service center in advance when going to ensure that the staff will go again during normal working hours, avoid running empty and pay attention to safety on the way back and forth.
