When will SMS and voice disappear?

In this case, there is no sound in the text message from WeChat. Generally, if you are sure that the mute is not set, you can handle the phone like this. The specific operation steps are as follows:

1. Clean the phone cache thoroughly. Try to clean up the garbage before shutdown and restart.

2. Back up important data to restore factory settings, and then download WeChat again.

Generally most of them are caused by the above reasons. If it can't be solved, it doesn't rule out a hardware problem. If it is within the warranty period, it can be inspected after sale. Or a professional maintenance point to check it for you.
