Hello, in general, if you turn on the lock screen sound, it will ring when you lock the screen. In your case, it may be that you turn off the phone sound (that is, mute) or the voice is very low? Of course, many of them are caused by too many background running programs of the mobile phone, and at the same time, please make sure that the sound of your mobile phone's shutdown lock screen has been turned on.
The solution is simple. Just turn off the "gaze sensing function". You can set the face ID and password (here you need to enter the unlock password once). After entering, you can find the "gaze sensing function" at the bottom.
I don't know about this, but I suggest replacing the tattooed lock screen, because since it was used, the mobile phone can no longer be used as a phone
