The restart of the mobile phone shows that you have a new dialing reminder. What happened?

There is a phone when the phone is turned off. Dialing reminder refers to the call reminder when the mobile phone calls. Every dialing reminder will be recorded. When the phone is restarted, it will be judged that the phone is turned off, and the dialing reminder will be automatically turned into a missed call and displayed in the call record. It will be displayed after the phone is turned on, so there will be a new dialing reminder.
