After about a month of beta testing, Samsung has kicked off the stable One UI 8.5 rollout for the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra. The update is currently live in South Korea, with other markets expected to follow shortly.
The firmware version rolling out is S91xNKSU7FZDT, and beta testers are getting first access before the update reaches devices still on One UI 8.0. That’s a familiar pattern for Samsung, and it typically means the broader global rollout is only a week or two away.
If you want to check for the update manually, head to Settings > Software update > Download and install. Samsung doesn’t always push updates to everyone at once, so if it isn’t showing up yet, checking manually can speed things along.
What does One UI 8.5 bring to the Galaxy S23?
One UI 8.5 is based on Android 16 QPR2 and comes with everything that entails, but Samsung has layered quite a bit on top of that. The update introduces a refreshed design language that makes the interface feel more polished and modern compared to One UI 8.0. Stock apps have been redesigned to match the updated look, and customization options have also been expanded.
If you’re curious about the full list of changes, our One UI 8.5 feature breakdown covers everything in detail. It’s a meaningful update for a two-year-old flagship, and Galaxy S23 owners are getting it sooner than many might have expected.
