Received a text message from a small speaker for no reason.

Small stereo, since it has been updated, why do you say that you have to refuel at 6: 30 every morning? No alarm clock is not used to affecting sleep? First of all, after the mobile phone is updated, it has many functions. Maybe you encountered something in the updated settings. You can ask a professional to have a look and see if there is a setting somewhere, just don't set it.
