i'm having the same problem, I've checked on my galaxy s9 for the one ui 2.0 almost everyday and nothing has showed up yet. I have the android 10 Good Lock app to the newest version but no actual device update. is there something else I can do?
Same here with my Note 9, it's kinda random, some S9/note9 users have the update already, others have to wait until not even Samsung knows when. Hoping by end of month at worst.
