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 suggested that you back up your data, enter recovery to clear all data (turn off your mobile phone, press and hold the volume up+power on button to enter recovery), upgrade your mobile phone to the latest development system with line 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.
