Samsung's One UI 9 list names the S23 and Fold 5, and skips the S25 Plus
Samsung Japan's first One UI 9 roster covers Galaxy S23 to S26, Fold and Flip 5 to 7 and several A-series phones, but it is not exhaustive and gives no patch dates.

Samsung's Japanese arm has published the first official roster of Galaxy phones and tablets that will move to One UI 9, the Android 17-based release, and the list is more useful as a map of what is missing than as a promise. If you own a Galaxy S23, a Fold 5 or a Galaxy A25, it says your device is in line. It does not say when, and it says nothing about how long security patches will follow.
What the list actually contains
According to Nokiamob, which describes the list as originating from Samsung Japan, the phones include the Galaxy S26, S25, S24 and S23 families (with the S24 FE), the Z Fold and Z Flip models from generation five through seven, and A-series handsets such as the A57, A55, A54, A36 and A25. Tablets run from the Tab S11 and S11 Ultra back to the Tab S9 series, plus the Tab S6 Lite (2024), Tab A11 variants and the Tab Active 5 Pro.
Samsung Japan's schedule covers October and November 2026. Coverage of the list, including hi-Tech.ua, adds a preliminary expectation that cheaper models and units outside Japan could follow in December 2026 and January 2027. Nokiamob does not name a source for that second phase, so treat it as an informed guess rather than a Samsung date.
Where the reporting is thin
All three outlets we checked trace back to the same Samsung Japan announcement, so this is one release repeated, not three independent confirmations. It also appears to be published largely as an image, which hi-Tech.ua notes means the model names are not in the page text. We could not retrieve Samsung's own page directly, and two other Galaxy news sites refused automated access, so the device names above rest on Nokiamob's transcription.
The omissions matter. Nokiamob flags that the Galaxy S25 Plus and S24 Plus are absent, along with several regional A-series models, and calls the list "not exhaustive". The sensible reading is that the list reflects what Samsung sells in Japan. Hi-Tech.ua makes the same point from the other direction: a model's absence does not confirm the end of its software support.
The rollout is already ahead of the list
The list lands after the update has begun. Reports say the stable build started on the Galaxy S26 series in September, and an earlier NPowerUser schedule forecast the S25 line, Z Fold7 and Z Flip7 for early October. That forecast was explicitly a prediction, not a Samsung announcement, and cited no build numbers; the same piece tied the S24 generation's Korean timing to stability across Korean carriers. Our earlier reporting on the Galaxy S24 staged rollout covers that group in more detail.
So a phone that is on this list can still sit for weeks. Rollouts are staggered by region, carrier and whether the owner was in the beta.
What to do with it
- Check Settings, then Software update, then Download and install, rather than waiting for a notification.
- If your model is absent from the list, check your own country's Samsung support page before concluding anything; Japan's lineup is not yours.
- For an older Galaxy bought used, an upgrade to One UI 9 tells you the feature release is coming. The security-patch end date is a separate question that none of these reports answers.
The catch is the one Samsung's update announcements usually carry: a list says who is eligible, not who is already updated or how many patch years remain. Until Samsung publishes a global roster, the Japan list is a good sign for the S23 and Fold 5 generation and a blank for everything else.
