Why is there a sudden message notification sound when recording a video?

When recording a video, there was a sudden message notification sound. It was when there was a message on WeChat or a text message came in during the shooting, so there was a vibration sound.

The solution is as follows:

The sound of the mobile phone system settings is low or muted. Just turn up the volume at this point.

You turned off WeChat’s new message notification sound. Then open settings--new message notification--select sound.

You may not have turned on the speaker function in WeChat, so if the sound does not go through the speaker (the sound is played in the earpiece), you cannot hear the sound. Select General--Turn on the handset mode.

The other party did not speak when recording the WeChat message, or there was something wrong with the other party's microphone, so there was no sound.

Maybe the other party did not turn on the recording function in the software permissions, so the message sent was silent! Just turn it on as follows.
