How to solve the problem of no sound in mobile phone calls?

If you use Huawei mobile phone and the call sound is abnormal, please follow the following steps:

First, check whether there is something wrong with your equipment.

If you encounter this problem only when talking to a specific person, the device you are talking to may be out of order.

Secondly, check whether the equipment signal is normal.

If the equipment signal is abnormal, it will affect the call quality.

Please turn up the volume when you make a phone call.

Fourth, make sure that the sound hole of the receiver or speaker is not blocked.

Please ensure that the equipment uses a matching protective casing and sleeve to avoid the sound outlet position of the receiver or speaker being blocked.

5. Please try again after restoring all settings.

Restoring all settings means restoring the settings in the mobile phone system to the default state, such as all network settings, fingerprints, face information, screen lock password, Bluetooth, desktop and wallpaper, application permission settings, etc. This operation will not delete any data or files.

Please follow the following methods:

1. Please enter the settings and enter them to restore all the settings in the search box;

2. Enter the page of restoring all settings, and click "Restore all settings";

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

If your phone doesn't have a screen lock password, you don't need to enter a password.

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. (EMUI or above is not involved)

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.

Tip: Please back up your own data before restoring the settings (QQ, WeChat and other third-party applications need to be backed up separately).

Sixth, get more help.

If the call of your device is still abnormal, please contact Huawei's customer service hotline (950800), or back up the data in advance (third-party applications such as QQ and WeChat need to be backed up separately), and bring relevant purchase vouchers to the nearby Huawei customer service center for more help.
