Samsung’s One UI 9 Plans Surface, These Galaxy Phones Are First in Line for Android 17

Samsung’s early One UI 9 roadmap is beginning to take shape, and the clearest signal so far is that the company is already testing Android 17 across a wide range of Galaxy devices. Internal server builds suggest that the next major software wave is being prepared well before a public rollout begins.

The most notable detail is that the testing covers not only upcoming flagships, but also older premium phones, foldables, tablets, and several Galaxy A models. That breadth points to a broad update strategy rather than a limited first-wave release.

Flagship Galaxy S models are already in testing

According to findings cited by SammyGuru, beta testing for One UI 9 is underway on the Galaxy S26 series. Internal build traces also show active testing for several earlier Galaxy S models that are expected to remain within Samsung’s software support window.

The presence of these devices does not mean they are the only ones eligible for the update. It does, however, show that Samsung is already preparing One UI 9 across multiple generations of its flagship line.

Foldables and tablets are part of the same rollout plan

Samsung’s foldable lineup is also appearing in the internal testing records. The list includes the Galaxy Z Fold 8 Ultra, Galaxy Z Flip 8, Galaxy Z Fold 8, Galaxy Z Fold 7, and Galaxy Z Flip 7.

That same pattern extends to tablets, where several Galaxy Tab models have surfaced as well. The detected devices include the Galaxy Tab S12+, Galaxy Tab S12 Ultra, Galaxy Tab S11, Galaxy Tab S11 Ultra, Galaxy Tab S10+, and Galaxy Tab S10 Ultra.

Samsung is also expected to bring new large-screen foldables to its next Unpacked event, although hardware is not the only focus. The software work already visible in the test builds suggests that One UI 9 will be a central part of that launch cycle.

Galaxy A models are not being left out

The software testing is not limited to flagships and premium foldables. Samsung has also surfaced several Galaxy A devices in the internal build records, indicating that the update path is being prepared for more affordable models as well.

That broader coverage matters because Samsung usually starts with its latest premium devices before widening availability to older generations. Seeing Galaxy A models in the same internal process suggests the company is already planning beyond the first launch tier.

Early features are beginning to emerge

A few One UI 9 features have also started to surface. One of them is a simpler way to trigger Lockdown Mode, which could make the security function easier to reach when needed.

Samsung is also preparing an option to block internet access for selected apps. That feature could appeal to users looking for more granular control over privacy and app-level connectivity.

Another early change involves image editing, where One UI 9 is expected to suggest edits to the user. The exact behavior has not been detailed, but it points to a more assistive editing experience.

For now, the internal build activity should be read as a sign of preparation rather than a final public rollout list. Models not yet visible in testing can still be added later, especially if they remain within Samsung’s official software update cycle.

One model name that has not appeared in the active testing set is the Galaxy S23, which is still widely expected to receive One UI 9 as its last major OS update. The same expectation is also being discussed for the Galaxy Z Fold 5 and Galaxy Z Flip 5.

As Android 17 continues to move forward on Pixel devices, Samsung appears to be lining up its own response with a wide test footprint across phones, foldables, and tablets. The next few weeks are likely to reveal more as testing expands and new devices continue to surface in internal builds.
