cell phone question
The phone rings once in the middle of the night and I trace it to a specific number, a friend. Friend claims his phone was on charger and that he did not make any calls at this hour. How is it possible for this to happen? He lives alone. Is it possible the phone while being charged was dialing automatically the last number that had been called earlier in the day? No one else could have access to his phone. It has happened more than once. Please explain.
