How to set the call sound when Huawei enjoys 9s?

The voice quality of mobile phone calls is mainly affected by the signal quality of related audio equipment and mobile phone network. If there is abnormal incoming call sound on your mobile phone, please follow the following steps:

1. Please make sure that the receiver is not blocked or blocked (it is not necessary to check the sound hole of the receiver when using the off-screen talking phone).

Please pay attention to observe whether the protective sleeve/shell or film covers the receiver; If the receiver is dirty and blocked, try cleaning it with a soft brush dipped in alcohol.

2. 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 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.

(2) If the detected sound is normal, please proceed to the next step.

Please turn Volte on or off again to see if the phone is back to normal.
