Samsung has begun delivering its One UI 8 update (based on Android 16) to the Galaxy Tab A9+. The release brings visual refinements and new features, and the company has started the rollout in Europe with firmware version BYKG.
What’s coming with One UI 8 on the Tab A9+
One UI 8 focuses on a cleaner look and added functionality across Samsung tablets. Early reports and changelogs point to refreshed visuals, improved widgets and lock screen behavior, plus fixes for a few issues that surfaced in earlier One UI 8 builds — such as dynamic wallpaper and Adaptive Clock quirks that some users experienced.
- Visual polish across system menus and widgets
- New and updated lock screen features
- Bug fixes for dynamic wallpapers and clock behavior
- Foundational improvements that prepare the device for future One UI 8.5 changes
Where and how you’ll get the update
The initial rollout is live in Europe with firmware BYKG. Samsung says other regions should receive the update in the coming days — rollouts often stagger by carrier and country.
To check for the update manually: go to Settings > Software update > Download and install. Before installing, make sure your tablet is connected to Wi‑Fi, has sufficient battery (or is charging) and consider backing up important data.

Already seeing problems? Small fixes and tips
If you encounter Adaptive Clock not working or related lock screen oddities after updating, try updating Samsung's LockStar module from the Galaxy Store if available — some users found that fixes roll out through companion apps rather than the main firmware. And if dynamic wallpapers act up, look for a subsequent incremental patch; Samsung has already issued follow-ups to address these issues on some devices.
What about One UI 8.5 — is the Tab A9+ eligible?
Yes. Samsung is developing One UI 8.5, a mid-cycle refresh that promises a more customizable interface and additional features for phones and tablets. The Galaxy Tab A9+ is listed as eligible for that update, so consider One UI 8 the stepping stone toward a more flexible, feature-rich release later on.
In short: if you own a Tab A9+, keep an eye on Settings for the BYKG package and install when convenient. The update modernizes the interface and lays the groundwork for future One UI enhancements.
