Xiaomi 1S automatically quits when it opens the SMS in standby mode, which can only be solved by restarting, but it automatically quits when it opens the SMS later.

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.

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