Just get on the latest oneui 6 beta. It’s stable enough to daily now. I literally have no glitches whatsoever, the only thing not working is google wallet and google pay.
Go to the samsung members app and swipe through the banners at the top until you find the oneui 6 beta banner.
Tab s8 ultra will get OS updates up to one ui 8 (android 16) and then another year of security updates. So 2026 is when OS updates stop and 2027 is when security updates stop.
The updates for the tablets always take a little longer to be rolled out compared to the phones.
Wait the two months for the s24.
