What's wrong with BBK mobile phone without sound?

It is recommended that you try to solve the problem as follows:

1. First, please confirm whether there is a speaker fault. If it's a phone hardware problem, I suggest you take your phone to our after-sales service center and let our staff help you deal with it.

2. Confirm whether the SMS ringtone is set to mute. You can go to phone settings-sounds-message ringtones-and change other ringtones.

3. To confirm whether the ringtone volume has been turned off, you can press the volume plus key in the standby interface of the mobile phone to increase the ringtone volume.

4. Enter phone settings-More settings-Restore factory settings-Restore all settings/Clear all settings (Restoring all settings will not clear the data in the phone, please back up the data in the phone before clearing all data).
