Call someone and they can't hear you. Send a voice and they can't hear you either. What happened?

The voice quality of mobile phone calls is mainly affected by the signal quality of related audio equipment and mobile phone network. If you are using a Huawei mobile phone, please follow the following steps to find out whether the call sound is abnormal:

1. Please make sure that the microphone is not blocked or blocked.

Please pay attention to observe whether the protective sleeve/shell or film covers the microphone; If the microphone 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 (third-party applications such as QQ and WeChat 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.

3. Please restore all settings and try again.

(1) Please enter the settings in the search box and press enter to restore all the settings;

(2) Enter the Restore All Settings page and click Restore All Settings;

(3) After entering the screen lock password, confirm it again and click Restore all settings.

Warm reminder:

If your phone doesn't have a screen lock password, you don't need to enter a password. If you forget the screen lock password, please try to get it back.

The path of EMUI 5.0 is set to >; Advanced settings > backup and reset. When the reset settings are used, the switch of the application avatar will be turned off, resulting in the loss of the application avatar data. Please back up the application data before this operation.

After all the settings are restored, when you set the face or fingerprint to unlock, you need to enter the application lock password to verify the binding. If you forget the application lock password, please try to retrieve it.

If you still can't solve the problem, please back up the data in advance (third-party applications such as QQ and WeChat need to be backed up separately) and bring the purchase voucher to the nearby Huawei customer service center for testing.
