Samsung has published the list of Galaxy devices that will receive One UI 9, its Android 17-based interface. The rollout began in September 2026 with the Galaxy S26 series, and the list, posted by Samsung Japan, covers close to forty models. Meanwhile, a rumor claims the base Galaxy S27 could go back to 8GB of RAM as memory prices climb.
One UI 9: which Galaxy devices are included?
Samsung Japan posted the list, and 9to5Google, which covered it on October 23, expects it to apply globally. It is not exhaustive: it leaves out the “Plus” models of some recent Galaxy S phones, many Galaxy A devices and devices sold in other regions.
- Galaxy S: S26, S26+, S26 Ultra, S25, S25 Ultra, S24, S24 Ultra, S24 FE, S23, S23 Ultra.
- Galaxy Z: Z Fold 7, Z Flip 7, Z Fold 6, Z Flip 6, Z Fold 5, Z Flip 5.
- Galaxy A: A57, A55, A54, A36, A25.
- Tablets: Tab S11 and S11 Ultra, the Tab S10 family (S10, S10+, S10 Ultra, S10 FE, S10 FE+, S10 Lite), the Tab S9 family (S9, S9+, S9 Ultra, S9 FE, S9 FE+), Tab S6 Lite (2024), Tab A11, Tab A11+ 5G and Tab Active 5 Pro.
The rollout timeline
In Japan, Samsung says every listed device will get the update in October and November 2026. Globally, the company will keep rolling it out after November. 9to5Google expects many entry-level devices to be served in December 2026 and January 2027, but that is the outlet’s estimate, not a Samsung commitment.
Updates are already landing on several models. The Galaxy S23 has received One UI 9 globally, and more modest devices such as the Galaxy A17 4G and the Galaxy A36 (in the US) have it too.
One UI 9: a fairly quiet update
For context, 9to5Google describes One UI 9 as one of the smallest updates in recent memory. One UI 7 overhauled the lock screen and app drawer, One UI 8 mostly brought quality-of-life tweaks, and One UI 8.5 introduced Liquid Glass-style design touches. If you were waiting for a big shake-up, it will have to come later.
And later is already in the works. According to leaker Ice Universe, Samsung is developing One UI 10, based on Android 18, with changes “unprecedented in nature.” Nothing is confirmed: no features are known, and the name “Galaxy OS” has surfaced without a clear origin. Google is expected to share more at the Android Dev Summit on October 28 and 29, 2026.
Galaxy S27: 8GB of RAM instead of 12GB?
Another rumor, and one that hits your wallet harder. According to leaker @kro_roe, reported by 9to5Google on October 20, the base Galaxy S27 and S27+ would start at 8GB of RAM, versus 12GB on the S25 and S26.
- Galaxy S27 and S27+: 8GB/256GB or 12GB/512GB.
- Galaxy S27 Pro: 12GB/256GB or 12GB/512GB, with a 16GB option under consideration.
- Galaxy S27 Ultra: 12GB/256GB, 12GB/512GB or 16GB/1TB.
The reason given is the surge in memory costs, which the article ties to the AI industry straining RAM supply. The leaker adds that price increases may be unavoidable, that pre-order promotions such as doubled storage may disappear, and that some models could get different UFS storage versions to control costs, whereas the S26 line uses UFS 4.0 across the board.
A separate leaker on Weibo claims several Android brands will cut top-end models to 12GB, mid-range to 8GB and entry-level to 6GB, with most budget phones going back to 4GB. Android runs poorly on 4GB, which is why recent entry-level phones moved to 6GB. All of this remains unconfirmed rumor.
What it means for you
If you own a recent Galaxy, One UI 9 should reach your device before the end of the year without much drama. If you are planning a purchase, keep in mind that pricier memory is weighing on tomorrow’s spec sheets. Which Galaxy do you use, and have you received the update yet? Tell us in the comments.
