Huawei's mobile phone sounds inexplicable?

If your Huawei mobile phone has a ding-dong prompt inexplicably, there may be the following reasons:

Receiving new information or notification: This is the most common reason. You can check whether there are any new messages, emails, social media notifications, etc.

Low battery power: When the battery power is lower than a certain level, Huawei mobile phone will automatically give a warning sound, so please charge it as soon as possible.

Security application takes effect: In order to protect the security of the mobile phone, Huawei mobile phone may start the security application, and may give a prompt when the phone locks the screen.

Small program reminder: WeChat, Alipay and other small programs. It will also send a message and give a prompt tone.

There is something wrong with the phone software: this may cause the phone to keep making sounds. Please try to restart your phone.

If it still can't be solved, I suggest you refer to Huawei's official mobile phone community or contact Huawei's customer service.
