I fell asleep at night 1: 30, and the next day I found a long record of sending messages to strangers from 2: 49 to 3: 00 on my mobile phone. Why?

You have met a ghost or your mobile phone is too smart. It has its own thoughts. Once, I saw my mobile phone flashing, so I unlocked it. I found a college classmate chatting with me on qq, but there was only his record. The content is not talking to himself, but more like talking to someone. Then I thought that a friend logged into my number and went back to check the roaming record, or was it just his message record? I asked him if he didn't understand, and then I left it alone. Anyway, it's time for you to burn incense
