What's the matter with no sound on the cell phone?

If you are using a vivo mobile phone, you can investigate and deal with it in the following ways:

1. Go to Settings-Sound and Vibration-Turn off the mute, select "Ring 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 prompt for incoming calls at this time, please enter Settings-Sound and Vibration/Sound Vibration and Mute Key-Focus Mode/do not disturb mode-enter the corresponding scenario-turn off the function;

3. Restart the phone and see if it recovers;

4. Go to 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 set wallpaper, unlocking style, WiFi, default startup program, desktop layout, etc.), and some third-party application accounts need to log in again. Please make sure that it will not affect the use of the software before operating. For the sake of data security, it is recommended to back up the mobile phone data in advance before operation. (You can enter the cloud service-device cloud backup-backup data type-system data-return-immediately back up some backup system settings and desktop layout; Cloud service-data synchronization-turn on WLAN, Bluetooth, etc. to synchronize data to cloud service)

5. If the above methods cannot be solved, please back up the important data on the mobile phone in advance and take the mobile phone to the vivo customer service center for testing and processing.

Tips: It is recommended to bring relevant purchase vouchers (such as purchase invoice/warranty card/ID card) when going, and call the staff of the service center in advance 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.
