We might have a 6th beta !! according to ice universe. I hope we do, animations didn't improve drastically from One UI 4. the device feels smooth for couple of days after the update then goes back how it used to be.
Yes we are getting close. My phone is running fine and this is one of the best beta programs I have seen. My very first time testing in the program. I bricked my phone so yes. I'm very happy.
