Samsung is Testing Android 17-Based One UI 9 for These Galaxy Devices

Samsung is in the final stages of One UI 8.5 stable rollout and could wrap it up before the end of this month. At the same time, the company is also quietly working on its next major software update — Android 17-based One UI 9. According to early reports, Samsung could officially debut the stable version around late July. This post lists out all the devices that have appeared with One UI 9 test builds so far.

Samsung expands One UI 9 internal testing

While One UI 8.5 remains Samsung’s immediate priority, internal testing for One UI 9 has already begun for several Galaxy devices. The beta program is already live for the Galaxy S26 series, with other devices like the S25 lineup and Z7 foldables expected to join the beta testing as well. The stable version will debut with Samsung’s next line of foldables — the Galaxy Z Fold 8 Ultra, Galaxy Z Fold 8 (Wide), and Galaxy Z Flip 8.

As of now, these Galaxy devices have appeared with One UI 9 test builds on Samsung’s internal servers in select regions:

S series

• Galaxy S26
• Galaxy S26+
• Galaxy S26 Ultra
• Galaxy S25
• Galaxy S25+
• Galaxy S25 Ultra

Foldables

Tablets

More older flagship, foldable, tablet, and midrange Galaxy devices are expected to start appearing with One UI 9 test builds soon. This will happen as Samsung moves closer to the official rollout timeline.

As for changes, One UI 9 is not expected to be a massive overhaul like recent versions. Instead, Samsung seems focused on refining the software further with better readability, smoother animations, cleaner layouts, and a more simplified overall experience. That said, the update could introduce a few new features like Tap to Share. This feature may work similarly to AirDrop for quicker file transfers between devices.

One UI 9 is still in early development, and more details should become clearer as additional test builds appear. Samsung’s roadmap may also evolve over time. So, we will have to wait for more official announcements for a clearer picture.
