Samsung has begun showing clear signs of testing One UI 9.0 on the Galaxy Z Fold 5 and Galaxy Z Flip 5. The development matters because these 2023 foldables are the oldest Samsung foldables still eligible for the next major interface based on Android 17.
The first clue came from firmware files for both devices appearing on Samsung’s servers. That discovery was tracked by Tarun Vats and suggests that early software testing for the two models has already started.
Why this matters for Fold 5 and Flip 5 owners
For Galaxy Z Fold 5 and Galaxy Z Flip 5 users, the appearance of these firmware files is a strong signal that Samsung is preparing more than just its newest foldables for the next software cycle. The previous generation is now entering the early stages of a major update path.
Although the files have surfaced on Samsung’s servers, the firmware versions themselves have not been identified. That means the current stage appears to be internal testing rather than a public rollout plan.
| Device | Role in Samsung Foldable Lineup | One UI 9.0 Status |
|---|---|---|
| Galaxy Z Fold 5 | Oldest eligible foldable model | Firmware detected on Samsung’s servers |
| Galaxy Z Flip 5 | Oldest eligible foldable model | Firmware detected on Samsung’s servers |
What One UI 9.0 is expected to bring
One UI 9.0 is Samsung’s latest interface for Android phones and is built on Android 17. The update is said to include a more customizable Quick Panel, giving users more flexibility in arranging fast-access controls.
Samsung is also preparing improvements for Game Booster, Samsung DeX, and Samsung Notes. Accessibility features are getting refinements as well, showing that the update is aimed at both usability and broader day-to-day comfort.
Those changes could be especially relevant on foldable devices. Game Booster matters for users who play on the move, while DeX and Samsung Notes are closely tied to the larger-screen productivity experience that foldables are known for.
Where Samsung appears to be in the rollout plan
Samsung introduced One UI 9.0 last month through a beta release for the Galaxy S26 series. That move marked the beginning of the company’s next software cycle before it expands to other devices.
The stable version of One UI 9.0 is expected to arrive first on Samsung’s next foldables, namely the Galaxy Z Fold 8, Galaxy Z Fold 8 Ultra, and Galaxy Z Flip 8. Those models are reportedly scheduled to arrive this month.
If that timeline holds, the Fold 5 and Flip 5 may receive One UI 9.0 after the newest foldables are introduced with the final software build. The pattern suggests Samsung is using its latest devices to debut the stable release while older foldables continue moving through internal testing.
For now, the newly spotted firmware files are the clearest sign that Samsung is preparing One UI 9.0 for the Galaxy Z Fold 5 and Galaxy Z Flip 5. A public beta or stable release has not been announced, but the update is clearly getting closer for two of Samsung’s most important foldables.
