Sometimes I am facing an issue with my IQOO 9SE the problem is my phone gets hang or sticks in some point screen will not responds on touch to operate or to buttons after a very long press of power off button near by a minute then it will restarts and starts functioning again, especially I noticed this issue while gaming & videocalls and more often on screen casting with TV.  Whats the solution for it irritates much sometimes on some important things or with some important persons.
