Why does Xiaomi's short message pop up to reply to the short message? I clearly replied, but I didn't send it out.

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, go to recovery and clear all data (turn off your 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 don't install the application software that requires root permission for the time being to see if it can be restored to normal.

For the sake of the system security of the mobile phone, please don't use root permission at will.

1. Software with root permission can completely control your mobile phone.

2. Opening root permissions may lead to system instability, crash, abnormal charging and other problems.

3. SMS, telephone and other functions may not work properly.

Therefore, we don't recommend that you open root permissions at will.
