What if there is no sound on the mobile phone?

There is no sound processing method for incoming calls from vivo mobile phones:

1. Go to Settings-Sound and Vibration-Turn off mute, select "ringtone mode" and turn up the ringtone volume; If there is a mute button on the side of the fuselage, you can dial the mute button up to cancel the mute mode;

2. If you enter do not disturb mode/Focus mode, there will be no incoming call prompt at this time. Please enter Settings-Sound and Vibration/Sound Vibration and Silent Keys-Focus Mode/do not disturb mode-Enter the corresponding scene-Turn off the function;

3. Restart the phone to see if it is restored;

4. Restore all settings, Origin OS/FunTouch OS 9.2/IKO Monster UI and above: enter Settings-System Management-Backup Reset-Restore all settings;

The following Funtouch OS 9.2: Enter Settings-More Settings-Backup and Reset/Restore Factory Settings-Restore all settings (Restoring all settings will not delete files in the mobile phone, so it is recommended to back up in advance to avoid operational errors).

If the above methods fail to help you recover, it is recommended to send your mobile phone to vivo customer service center, and professional and technical personnel will serve you enthusiastically. Enter the mobile phone vivo official website app-Service-My Service-Service outlet and find the address and telephone number of the nearest customer service center outlet.
