Why does my mobile phone often sound a short message prompt, but there is no information when I take it out to check?

This may be a warning that the battery is low. . Or other prompts in the system.

It just sounds like a text message.

It shouldn't be a serious problem. Why don't you set it to silent mode to check for sound? .

Of course, it may also be the problem of anti-virus software. Please close the software and try again. .

In a word, I don't think it's the phone, but I didn't set it up properly. . The comrades above are either moving or repairing. . After all, the mobile phone is worthless when it is repaired, and my heart will feel uncomfortable.
