What if there is no sound on the mobile phone?

First, please turn the down switch on or off.

1. Confirm that the phone is not silent, please drop down the status bar to check.

2. Confirm that "Do Not Disturb" mode is turned off.

Enter the settings, search for do not disturb mode, and then click Enter. If yes, please turn off do not disturb mode.

3. Confirm to turn off the mute notification switch (this operation is only applicable to EMUI 10. X/ 1 1.0)。

Enter settings, search application management, find information, click notification management, select the corresponding card 1/ card 2 in the category, and turn off the mute notification switch.

Second, the message received did not vibrate or ring.

1. Please confirm whether the notification bell of the message is set to None or whether the vibration switch is turned off (only applicable to EMUI 9. x)。

Enter the settings, search into the application management, find the information, click the notification management, and check whether the notification ringtone is selected as None or the vibration switch is turned off. If yes, please set the notification bell and turn on the vibration switch.

2. Please confirm whether an incompatible third-party theme is used.

It is recommended that you change the official default theme. Go to themes > my > preset a theme, select one and apply it.

Third, clear the data.

It may be that the information data is abnormal. I suggest you try to clear the data. The operation method is as follows:

1. Go to Settings, search Application Management, find the information, click Save > Delete Data, then restart the phone and try again.

2. Try to restore all settings: Go to Settings, search to restore all settings, and then click the Restore All Settings option.

Warm reminder: the path of EMUI 5.0 is Settings > Advanced Settings > Backup 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 the above method has not solved your problem, I suggest you back up the data in advance (WeChat /QQ and other applications need to be backed up separately) and take the purchase voucher to Huawei customer service center for testing.
