Why does my mobile phone have automatic software to send text messages automatically?

Your mobile phone has been tampered with, which will cause the following situations 1: the mobile phone is equipped with spyware, the so-called mobile phone virus, which consumes the phone bill of consumers by automatically sending text messages and making internet calls (most likely, I suggest you go to customer service in 60 yuan to kill virus or reinstall the system); 2. Your mobile phone has been used by others; 2. You have started a certain business (unlikely). Good luck 1.
