What if there is no sound when the phone calls?

If you use a vivo phone, you can check the following methods:

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. After backing up the data, go to Mobile Phone-System Management/More Settings-Backup and Reset/Restore the factory settings, and restore all settings.

This operation will not delete the data in the mobile phone, but will restore all the settings in the mobile phone, including the set wallpaper, unlocking method, WiFi, default opening program, etc. And the third-party software account registered in the mobile phone needs to log in again.

It is suggested that you can enter cloud service-device cloud backup-backup data type-system data-return-and immediately back up some backup system settings and desktop layout; Cloud service-data synchronization-turn on WLAN and Bluetooth to synchronize data to cloud service.

5. If the above methods are ineffective after operation, you can take the mobile phone and purchase certificate to the customer service center for testing and processing in time. Address of customer service center: Go to the service outlets of vivo official website /vivo Mall APP-mine-or the webpage version of vivo official website-slide to the bottom-service support-service outlets query-select provinces and cities to query the address of customer service center. It is recommended to call in advance before going to avoid empty running, plan your trip reasonably and travel safely.
