| Launch timing | Samsung announced the program on May 12, 2026, with rollout beginning that week. |
| First devices | Samsung says the beta begins with the Galaxy S26 series; reports name Galaxy S26, Galaxy S26+ and Galaxy S26 Ultra as the first models. |
| First reported countries | Germany, India, South Korea, Poland, the U.K. and the U.S. are reported as first-wave markets. |
| How to access it | Eligible users are reported to enroll through the Samsung Members app where the beta is available. |

Samsung’s official announcement keeps the device language broad: the One UI 9 beta is “beginning with the Galaxy S26 series.” A report relayed by Sina, citing SamMobile, is more specific and lists Galaxy S26, Galaxy S26+ and Galaxy S26 Ultra as the first supported models.
For countries, Android Central reports the first rollout in Germany, India, Korea, Poland, the U.K. and the U.S.; Sina’s report lists the same six markets. Gizbot separately says India is among the first countries and that the beta starts through the Samsung Members app.
That means the practical first step for S26 owners is simple: check Samsung Members, but only expect the beta if the program is live for the phone model and market.
Samsung’s own wording highlights four pillars: expanded creative tools, more customization options, a more accessible mobile experience and stronger protection against potential security threats. The available reporting adds a few more concrete examples.
One UI 9 adds more customization tools in Samsung Notes, including decorative tapes and new pen styles, according to Android Central. Sina’s report also points to new Samsung Notes tools as part of the beta.
Early hands-on coverage of a leaked One UI 9 build also reported a Photo Assist option that can automatically suggest editing prompts after analyzing a photo. Because that detail comes from hands-on coverage of a pre-release build rather than Samsung’s official feature list, it should be treated as a likely beta behavior, not a final-stable guarantee.
Samsung says One UI 9 includes expanded customization options and a more personalized experience. Reports also describe a new quick control panel, while SamMobile’s hands-on coverage of an Android 17-based One UI 9 build observed much thicker brightness and volume sliders in the quick panel.
Those interface changes look more like usability and visual refinements than a complete redesign, at least based on the available evidence. Earlier reporting on internal builds also characterized early One UI 9 changes as relatively minimal compared with larger One UI 8.5 interface changes.
Accessibility is one of Samsung’s named focus areas for One UI 9 beta: the company says the update delivers a “more accessible mobile experience.” Sina’s report similarly describes enhanced accessibility features, though the available snippets do not list every specific accessibility setting or tool.
Samsung says One UI 9 beta brings stronger protection against potential security threats. The official announcement excerpts provided do not name each security feature, so the safest reading is that security is a confirmed pillar of the beta, while the exact feature-by-feature security list still needs Samsung’s full documentation or hands-on verification.
This is still beta software. PhoneArena’s coverage notes that the newest OS version is not ready for regular users yet and is aimed at people comfortable with beta-release risks. For most Galaxy owners, the stable release will be the safer update path.
Samsung has not provided a confirmed stable One UI 9 calendar for the Galaxy S26 series or older Galaxy devices in the available announcement text. TechRadar’s earlier coverage only framed the launch as expected sometime later in 2026, while one unofficial tracker lists July–August 2026 as an expected launch window, names Z Fold 8 and Flip 8 as first devices, and places a wider rollout in September–December 2026. Treat those windows as expectations, not Samsung-confirmed dates.
Older Galaxy owners should also avoid confusing One UI 8.5 rollout news with One UI 9 eligibility. Samsung’s One UI 8.5 beta expansion covered devices such as the Galaxy S24 series, Galaxy Z Fold6, Galaxy Z Flip6, Galaxy S25 FE, Galaxy S24 FE and Galaxy Tab S11 in select markets, and later expanded to models including the Galaxy S23 series, Galaxy Z Fold5, Galaxy Z Flip5, Galaxy S23 FE and Galaxy A36 5G. Those are One UI 8.5 programs, not official One UI 9 schedules.
Separately, a PhoneArena report based on a leak says some Galaxy S26 features were expected to reach older models such as the Galaxy S24, including Call Screening, Creative Studio, Audio Eraser, New Photo Assist and AI Select, while Privacy Display was not expected to come to older phones. Samsung UK describes Privacy Display as a built-in Galaxy S26 Ultra display feature, so it should be treated differently from software-only AI features.
If you own a Galaxy S26-series phone in one of the reported first-wave countries, One UI 9 beta access should appear through Samsung Members when available. If you own an older Galaxy device, there is not yet a Samsung-confirmed stable One UI 9 rollout date or model list in the provided evidence; current older-device information is either about One UI 8.5 or unofficial S26 feature backports.
