You're right.I guess this hasn't made it to the T-Mobile users yet. My S21 Ultra still says that its June 1 security update is the most current.
Sounds about right.So is the last update for the S21 Ultra in Feb 2026?
Samsung should have released one UI 8 to all devices available, they waste time by s25 then Fold 6 And s24 etc...Samsung have begun rolling out the August 2025 security update for the S21 series on Android 15/One UI 7.

Such a bummer. The S21 Ultra is still one of my favorite devices of all time. Despite upgrading to an S23 Ultra recently, I am definitely hanging onto mine.Sounds about right.
