Samsung has already started rolling out the stable version of One UI 8.5 to select Galaxy smartphones, but the update has so far reached only a limited number of devices. Several older Galaxy models, including last year’s flagship lineup, are still running the beta version and are expected to receive the stable build later this month. Despite the ongoing rollout, Samsung has reportedly moved ahead with testing its next major interface update — One UI 9.
The upcoming One UI 9 will be built on Android 17 and is already believed to be under internal testing for the upcoming Galaxy S26 series. Even before Samsung officially confirms the software, multiple leaks have surfaced revealing some potential improvements and new features expected in the next-generation interface.
According to early reports, One UI 9 may introduce a more refined browsing experience, improvements to the Now Bar, and upgraded home screen widgets. Samsung is also said to be focusing on smoother navigation across system settings and delivering a more streamlined user interface throughout the operating system.
While Samsung has not yet announced details about the One UI 9 beta program or officially confirmed the list of supported devices, a Reddit user recently compiled a tentative list of eligible Galaxy devices. The list is based on Samsung’s software update policy and the number of Android upgrades promised for each device.
Based on that information, several Galaxy S series smartphones are expected to receive the update, including the Galaxy S26 lineup as well as the Galaxy S25, Galaxy S24, and Galaxy S23 series. Foldable devices such as the Galaxy Z Fold 7, Z Flip 7, Z Fold 6, Z Flip 6, Z Fold 5, and Z Flip 5 are also likely to be eligible.
Samsung’s Galaxy A series could see broad coverage as well. Devices such as the Galaxy A57, A56, A55, A54, A37, A36, A35, A26, A25, A24, A17, A16, and A15 are expected to receive the update depending on regional availability.
On the tablet side, the Galaxy Tab S11, Tab S10, and Tab S9 series are likely candidates, along with models like the Galaxy Tab A11 and Galaxy Tab Active 5 lineup.
However, Samsung has not officially confirmed the list, and older models are unlikely to receive updates beyond their promised software support timeline. More details about One UI 9 are expected once One UI 8.5 becomes widely available. The company may also reveal the stable version during the Samsung Developer Conference later this year.
