Why does my Xiaomi mobile phone keep ringing? I didn't do anything. I didn't text or call.

Hello, there may be some applications in your system that interfere with the normal operation of the system, especially some programs that get root permission. For the safety of your mobile phone system, please don't use root permission at will. It is recommended that you back up your data, enter recovery and clear all data (turn off the phone, press and hold the volume up+power on button to enter recovery), upgrade your phone to the newly developed system with a wire brush, and do not install the application software that requires root permission for the time being to see if it can be restored to normal. The brushing method is 1. Please download the official ROM package, ROM download:/topic-mirom.html2. Please brush the machine according to the brushing tutorial, which is/thread-3104435-1-kloc-0/.html3, and there is also a brushing video made of rice flour.
