How about Huawei's mobile video playing for a long time?

You should first check whether it is a low-power prompt or a prompt from the software running in the background. For example, 360 mobile guards will give a prompt when there is a robbery message, or it is a private message. There is no desktop prompt but a ringtone prompt.

Huawei's mobile phone doesn't ring because:

1, the volume of the mobile phone is not turned to the maximum, so I can't hear it. You can try to raise the volume.

2. The phone is turned on in silent mode, and the incoming call is silent. You can turn it off in phone settings-sound-mute mode.

3. The mobile phone speaker is damaged. In this case, you can only go to the mobile phone repair shop or Huawei for after-sales inspection and maintenance.
