Lenovo's mobile phone mutes when it receives a text message.

According to the description, it is recommended to refer to:

1. First check whether it is caused by touching the volume down button by mistake, because Android can control the switching of scene modes through the volume button;

2. If it is not caused by touching the volume button by mistake, then check whether power-saving software is installed. Some power-saving software may have the function of automatically adjusting the scene mode, and try to turn off related functions;

3. If it is not the interference of third-party power-saving software, it is generally caused by system abnormality. It is recommended to restart the mobile phone first. If the restart fails, the backup data will be restored to the factory settings, and some important files stored in the fuselage, such as SMS, address book, photos, software, etc. , can restore operation, so as not to cause unnecessary losses.

If the factory settings still cannot be solved, it is recommended to go to Lenovo maintenance site for inspection and maintenance in time.
