Why does BBK's mobile phone suddenly have no sound?

Is there no sound on the speaker or receiver of the mobile phone? Please describe it for convenience.

First, if your mobile phone has a mute speaker, I suggest you try to deal with it by referring to the following methods:

1, press the volume plus key to enhance the sound.

2. Enter the mobile phone settings-turn off the mute mode in the sound and set the mobile phone to the ringing state;

3. If a song is being played, please check whether there is sound in the speaker during the call and rule out the abnormality of playing music, video and other resources.

4. Restart the phone to see if it is restored.

5, enter the phone settings-more settings-restore factory settings-restore all settings to solve.

Second, the receiver has no sound. I suggest you restart your phone first to see if it has recovered. If the receiver still doesn't sound, I suggest you take your mobile phone to our after-sales service center, and professional technicians will test it for you. The address and contact information of the after-sales service center can be found in the Settings-More Settings-After-sales service menu.
