Samsung Galaxy Tab S11 and S11 Ultra receive One UI 8.5 stable update, rollout for S23 series expands to more regions
Samsung Rolls Out Stable One UI 8.5 for Galaxy Tab S11 and S23 Series
Samsung is officially hitting the gas on its latest software rollout. The stable One UI 8.5 update has begun its global journey, with the Galaxy Tab S11 and Tab S11 Ultra leading the charge as the first tablets to receive the upgrade.
The Tablet Pioneer: Galaxy Tab S11 Series
If you own the Galaxy Tab S11 or the powerhouse Tab S11 Ultra, your device is at the front of the line. The update is currently live for users in South Korea, and history suggests we’ll see it expanding to other markets very soon. For those who like to keep an eye on the technical details, here are the specific firmware versions to look for:
- Galaxy Tab S11 5G: X736NKOU5BZE3
- Galaxy Tab S11 Ultra 5G: X936NKOU5BZE3

The Galaxy Tab S11 Ultra is among the first to get the stable One UI 8.5 build.
Expanding the Reach: Galaxy S23 Series
It’s not just the new tablets getting all the love. Samsung is also pushing One UI 8.5 to last year’s flagship phones. After its initial debut in South Korea, the update is now landing on devices across Europe and India for the Galaxy S23, S23+, and S23 Ultra.
The download size varies depending on your current software status. If you’ve been testing the beta version, the jump to stable is a light 300MB. However, if you’re coming from the standard public version, expect a substantial 4GB download. The firmware version for this rollout is S91xBXXU9FZDP.
How to Check for the Update
While your device will likely notify you when the update is ready, you can always take matters into your own hands. To check manually, head over to Settings > Software update > Download and install. If it hasn’t appeared yet, don’t worry—Samsung typically releases these updates in waves, so it should arrive on your device shortly.
