Samsung is accelerating development of One UI 9, and the clearest sign is that internal test builds are now appearing for a much wider range of Galaxy devices. The rollout is no longer centered only on the newest flagship line, suggesting the company is broadening its testing plan earlier than many expected.
If the current timeline holds, the stable version of One UI 9 could arrive as early as July alongside Samsung’s next generation of foldable phones. That would make the update one of the company’s more closely watched software releases this year, even before it reaches the broader Galaxy lineup.
Testing now spans several Galaxy categories
Reports indicate that Samsung’s internal servers were already hosting One UI 9 test builds for multiple device families as of June 19. The list is notable because it extends beyond premium phones and into midrange models and tablets as well.
On the Galaxy S side, the devices mentioned include the Galaxy S26, Galaxy S26+, Galaxy S26 Ultra, Galaxy S25, Galaxy S25+, Galaxy S25 Ultra, Galaxy S24, Galaxy S24+, Galaxy S24 Ultra, and Galaxy S24 FE. That spread shows three generations of flagship phones have already entered the testing radar.
| Device Category | Models Mentioned for One UI 9 Testing |
|---|---|
| Galaxy S | Galaxy S26, S26+, S26 Ultra, S25, S25+, S25 Ultra, S24, S24+, S24 Ultra, S24 FE |
| Galaxy Z | Galaxy Z Fold 8 Ultra, Galaxy Z Fold 8 or Wide, Galaxy Z Flip 8, Galaxy Z Fold 7, Galaxy Z Flip 7 |
| Galaxy A | Galaxy A57, Galaxy A56, Galaxy A34, Galaxy A18, Galaxy A17, Galaxy A16 |
| Galaxy Tab | Galaxy Tab S12+, Galaxy Tab S12 Ultra, Galaxy Tab S11, Galaxy Tab S11 Ultra, Galaxy Tab S10+, Galaxy Tab S10 Ultra |
The foldable category is also already involved. Internal builds are said to be available for the Galaxy Z Fold 8 Ultra, Galaxy Z Fold 8 or Wide, and Galaxy Z Flip 8, along with the already released Galaxy Z Fold 7 and Galaxy Z Flip 7.
Samsung’s midrange strategy is visible too, with Galaxy A57, Galaxy A56, Galaxy A34, Galaxy A18, Galaxy A17, and Galaxy A16 all reportedly included. Tablets have not been left out, either, as the Galaxy Tab S12+, Tab S12 Ultra, Tab S11, Tab S11 Ultra, Tab S10+, and Tab S10 Ultra are also listed.
What One UI 9 is expected to change
One UI 9 is not being positioned as a major visual overhaul. The update is expected to focus instead on refinement, with smoother animations, improved readability, cleaner interface layouts, and a more streamlined day-to-day experience.
That approach suggests Samsung is prioritizing polish over a dramatic redesign. For many users, the bigger appeal may come from how the software feels in daily use rather than from obvious visual changes.
One of the more interesting additions mentioned is Tap to Share, a feature that is said to work in a similar way to Apple’s AirDrop for faster file transfer across compatible Galaxy devices. If delivered as described, it could become one of the practical features that gives the update broader appeal.
Even so, the development is still considered early. Features mentioned in current reports can still change before the wider beta phase or before Samsung finalizes the stable release.
Beta access is already widening
Earlier this month, Samsung reportedly expanded the beta program to the Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra in selected regions. The countries mentioned include India, South Korea, Germany, Poland, the United Kingdom, and the United States.
Users who want to try the software can sign up through the Samsung Members app. That staged approach matches Samsung’s usual pattern of opening beta access gradually before a broader stable release.
SammyGuru reports that the public beta is already running for the Galaxy S26 series, and more flagship phones and foldables are expected to join testing in the coming weeks. The company is also said to be preparing the stable debut of One UI 9 with upcoming foldable devices, including the Galaxy Z Fold 8 Ultra, Galaxy Z Fold Wide, and Galaxy Z Flip 8.
For now, the most striking development is not a dramatic new interface, but the scale of the testing itself. With phones, foldables, and tablets now appearing in the internal build pipeline, Samsung appears to be setting up One UI 9 for a much broader release than many users may have assumed.
