There is no sound in the incoming call, and there is sound in the answer? What happened?

If you use a vivo phone, there is no sound processing method for incoming calls:

1, enter Settings-Sound (and Vibration)-Turn off the mute and turn up the ringtone volume;

2. If the status bar shows the moon icon, it means that the mobile phone has turned on the do not disturb mode. Please enter Settings-(Sound and Vibration/Sound)-Do Not Disturb mode and turn off the switch.

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 and Reset-Restore all settings;

Funtouch OS 9.2 or below: Enter Settings-More Settings-Backup and Reset/Restore Factory Settings-Restore All Settings;

This operation will cause the logged-in third-party software account to log in again, but it will not clear the photos, videos and other files stored in the mobile phone. Before restoring all settings, please ensure that the use of some third-party software will not be affected. In order to avoid data loss caused by abnormal operation, it is recommended that you back up the important data of your mobile phone first.

If the above methods fail to help you recover, it is recommended that you bring your mobile phone and valid purchase certificate to vivo customer service center for testing and processing. Professional and technical personnel will serve you enthusiastically. You can pay attention to WeChat official account "vivo" or "vivo customer service" to inquire about the address and telephone number of the service center. It is recommended to call before you go to ensure that you are received by staff before you go to avoid wasting precious time.
