Why doesn't Huawei's mobile phone ring after locking the screen?

There are two possibilities. First, the volume of the mobile phone is turned off, just turn it on (turn it up). Second, the prompt tone is off and needs to be reset. The specific setting steps are as follows:

Mobile phone model: Glory 9x

Wechat version: 8.0.27

1. Open the mobile phone WeChat app, click Me at the bottom right, and then click Settings;

2. Click the new email notification on the settings page;

3. Open two gray buttons, namely, receiving new message notification and receiving voice and video call invitation reminder, on the setting page;

4. The button will turn green when it is turned on. Then click the new message notification in the chat interface of this page;

5. If the sound button is not turned on (it is gray if it is not turned on), it will turn green if it is turned on.

In this way, the mobile phone can normally receive the new message prompt tone of WeChat after the screen is locked, which is convenient for us to know that others have sent us a message at the first time.
