What should I do if my Xiaomi mobile phone intercepts the express message?

Hello, if you don't set the interception rules in the system's own anti-disturb, the system itself will not intercept the express message. It may be that some applications in your system interfere with the normal operation of the system, especially some programs that have obtained root permission. For the security of the mobile phone system, please do not use root permission at will. It is recommended that you back up your data, enter recovery to 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 that requires root permission for the time being to see if it can be restored to normal.

Thank you for your support and wish you a happy life!
