How to recover the phone without sound?

If you use a vivo mobile phone, the handset suddenly has no sound, you can refer to the following treatment methods:

1. If there is a third-party protective film, please confirm whether the film adhesive flows into the micro-cracks of the receiver. It is recommended to stick an official protective film in vivo customer service center;

2. When using the handset to answer the phone, you can press the volume increase button to increase the volume of the call.

3. If the phone is connected with a Bluetooth device, the sound will be played from the Bluetooth device (such as Bluetooth headset, car Bluetooth, etc.). You can go to Settings-(Other Networks and Connections)-Bluetooth and turn off the Bluetooth function to view.

4. Please observe whether the protective shell and protective film have sound holes blocking the receiver. If the sound hole is blocked, you can try to clean it or go to the customer service center to clean it.

5. If the positioning signal is not good, it will affect the call quality. It is recommended to go to the area with good signal for call test.

6. Comparative test of different contacts. If a number is abnormal, it may be because of the other party's mobile phone or network.

If the above methods fail to solve the problem, please back up the mobile phone data in advance and take the mobile phone and purchase certificate to vivo customer service center for testing. Address of vivo Customer Service Center: Go to the APP-My-outlet of vivo official website /vivo Mall and select the current city to get the address and contact information of the service center.
