So basiclly i pressed on app notification and it opened app but it was covering 90% of display and wasnt refreshing. I couldn't swipe the app off, change to different task. anything didnt work. Only 10%of display was refreshing and that was corners. I couldn't restart because the non-refreshing app was covering whole middle of screen. I had to restart my device by plugging it in pc at 23:30 I was hella sleepy and restart it with android fastboot thing in cmd. This happens since one ui 7.
