Why is Huawei mate8 mute?

If there is no sound outside the phone, you can troubleshoot it by the following methods:

1. Please check whether the headset icon is displayed on the phone.

If the headset is not plugged into the phone, the headset icon is still displayed, which will cause the phone to mute.

Please make sure that the speaker is not blocked.

Please ensure that the sound position of the horn is not blocked, such as protective shell, protective sleeve, etc.

3. Please try to clean the horn dust screen.

You can dip a long soft brush in alcohol and brush out the dust screen in the sound hole to see if the sound returns to normal.

4. Please check whether the sound of the equipment is normal according to the following methods.

Please open my Huawei APP/ service APP on your mobile phone and find my Huawei app> service > I want to test > other > device sound problem (service app> troubleshooting > more > other > device sound problem > start detection).

(1) If the detected sound is normal, it is suggested to restart the phone or change the playback sound source and try again;

(2) If abnormal sound is detected, it is recommended to back up important data in advance (WeChat /QQ and other applications need to be backed up separately) and bring the purchase voucher to Huawei Customer Service Center for professional testing.

If you still can't solve the problem or have questions after the above investigation, please back up the materials in advance (WeChat /QQ and other applications need to be backed up separately) and bring the purchase voucher to the nearby Huawei customer service center for maintenance.
