Xiaomi 10s can't hear the sound after connecting the mobile phone.

The general solution is to restart the phone.

If the mobile phone is in serious condition, deal with it directly after sale. The following are some simple explanations of the problems in the use of Xiaomi mobile phone: 1. If the key fails during use, it may be caused by a screen problem, and the screen needs to be replaced. 2. The screen has been tampered with during the charging of the mobile phone, which may be that the charger is not a regular product. 3. If you are prompted not to block the red area during the use of the mobile phone, it is caused by the anti-touch mode of the mobile phone. You can turn off this anti-touch function in the settings of your mobile phone.
