How to turn off Bluetooth sound?

If you use a vivo phone, you can refer to the following methods for troubleshooting:

1. If you enter the settings-sound and vibration/sound, mute key and vibration/sound-and turn on "Earphone Hearing Protection", when the earphone volume is too high, if you connect the earphone again, it will automatically decrease to a safe volume;

2. Observe the place where it is placed to see if it is easy to touch or rub the volume button or mute button by mistake;

3. Remove the protective shell and confirm whether the volume button is touched by mistake because the protective shell is not suitable in size;

4. Check whether the Bluetooth headset or other devices are connected, resulting in the adjustment of the volume;

5. Enter the multi-task switching interface and click the "X" icon to clear the background tasks for viewing;

6. Restart the equipment;

7. 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, 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 operation. For the safety of mobile phone data, it is recommended to back up 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-turn on WLAN, Bluetooth, etc. Synchronize data to cloud services)

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

Tips: It is suggested that you bring relevant purchase vouchers (such as purchase invoices/warranty cards/ID cards) when you go, and call the staff of the service center in advance to ensure that the staff will go again during normal working hours to avoid running empty, and pay attention to safety on the way back and forth.
