My notification bar was stuck when i was on call with a friend, i was unable to swipe it down or turn off the screen. When i turn off the screen, the lockscreen with fingerprint merged with my call display creating a really bad looking display. I will include a screenshot of the notification bar stuck even in my lock screen. I was unable to record this occurence because i couldnt pull my recorder. Its fixed when i restarted my phone but still it was annoying and idk how to replicate it. Get a stable update and fix all these bugs. In these photos you can see my notification bar is fully green and not functional and also messing up my display.
