I've got to say that in the 2.5 years that I've been running my Tab S8U 24/7 it has exceeded my update expectations, and Samsung's stated schedule receiving many, many monthly updates in addition to the quarterly ones.

I got it same day on my tab S8 plus. I'm in the process of upgrading to the tab S10 plus and it is not updated to the November patch yet. Hopefully soon.
