Here's a fully sourced guide to what's new, which devices get it, and when. > **How this article is sourced** _(info)_ > > Everything below is drawn from Samsung's official Global Newsroom and Samsung Mobile Press announcements, plus reputed independent reporting from Android Authority, SamMobile, How-To Geek and 91mobiles. Every source is linked at the end. [1][2][3][4][5][6][7] Samsung's next major software release — One UI 9, built on Android 17 — is no longer a rumor. Samsung officially announced the One UI 9 beta program on May 12, 2026, launching first for the Galaxy S26 series, and the software has since been confirmed running on the company's newest generation of foldables. [1][2][3] This article walks through what Samsung has officially confirmed, what independent outlets have verified from the beta builds, and what the rollout timeline looks like — with clear labels separating confirmed facts from expectations. ## 1. The basics: what One UI 9 is - Base operating system: Android 17. Google announced Android 17 in February 2026, and Samsung followed with its own Android 17-based skin in May. [3][6] - Beta program start: The week of May 12, 2026, beginning with the Galaxy S26 series in Korea and expanding to more regions. [1][2][3] - Stable availability: One UI 9 is officially running on Samsung's latest foldables, the Galaxy Z Fold 8 and Z Flip 8, with the wider flagship rollout following Samsung's usual staggered schedule. [3] - Positioning: Samsung describes One UI 9 as offering 'a more intuitive and personalized mobile experience with enhancements across creativity, accessibility and security.' [1][2] > **Where One UI 8.5 fits** _(note)_ > > One UI 8.5 — the Galaxy AI-focused refresh on Android 16 — began its stable rollout on May 6, 2026. One UI 9 is the true next-generation release: a new Android base, not a point update. [6] ## 2. What's new: the confirmed changes Android Authority published the official beta changelog and SamMobile documented the S26 Ultra build. The headline changes verified in the first beta include: [4][5] ### Redesigned Quick Panel The quick settings area gets a visual overhaul, continuing the layout experimentation Samsung began with One UI 7 and 8. Tiles, brightness and media controls are reorganized for easier one-handed access. [4] ### Samsung DeX upgrades DeX — Samsung's desktop mode — receives notable improvements in the One UI 9 beta, part of Samsung's ongoing push to make a Galaxy phone function as a full PC replacement when docked. [4] ### New privacy and security tools Samsung's own announcement explicitly names security as a pillar of this release, and the beta changelog includes new privacy controls building on Android 17's platform-level protections. [1][2][4] ### Creativity and personalization, with AI Samsung frames One UI 9 around 'expanded creative tools, customization options' and signals that more advanced Galaxy AI features are coming to the platform — continuing the pattern where each major One UI release deepens on-device AI integration. [1][2] ### Accessibility improvements Accessibility is one of the four named pillars in Samsung's launch announcement, alongside creativity, personalization and security — a notable explicit commitment rather than a footnote. [1][2] ## 3. Which Galaxy devices get One UI 9 Confirmed and reported so far: [1][3][7] - Galaxy S26 series — first in the beta program, and the expected first stable recipients after the foldables. [1][3] - Galaxy Z Fold 8 and Z Flip 8 — ship with One UI 9 officially. [3] - Older flagships (Galaxy S25 series and similar) — expected in the wider rollout, following Samsung's standard multi-year update policy; exact eligibility lists beyond the current flagships have not been formally published. [6][7] > **How to join the beta** _(tip)_ > > If you own a Galaxy S26 in a supported region, open the Samsung Members app and look for the One UI 9 beta registration banner. Beta slots are limited and region-dependent. [1][4] ## 4. The timeline so far 1. February 2026 — Google announces Android 17 and begins its own beta testing. [6] 2. May 12, 2026 — Samsung announces the One UI 9 beta program, starting with the Galaxy S26 series. [1][2] 3. May 13, 2026 — Beta changelog documented publicly: redesigned Quick Panel, DeX upgrades, new privacy tools. [4] 4. Mid-2026 — Galaxy Z Fold 8 and Z Flip 8 foldables launch running One UI 9 officially. [3] 5. Following months — Wider stable rollout expected across the Galaxy S26 series and eligible older flagships, on Samsung's usual staggered regional schedule. [6][7] ## 5. What Galaxy owners should know - If you own a Galaxy S26: you are first in line — beta now, stable next. [1][3] - If you own a Galaxy S25 or recent foldable: One UI 9 is expected for your device, but the stable build will arrive after the S26 rollout; in the meantime, One UI 8.5 is your current update. [6][7] - Beta software carries real risk: bugs, battery drain and app incompatibility are common. Samsung recommends backing up before enrolling. [1][4] > **Accuracy box** _(note)_ > > Beta features can change or be removed before the stable release, and rollout timing varies by model, carrier and region. Device eligibility beyond the Galaxy S26 series and 2026 foldables is based on Samsung's update policy and reporting — not a final official list.
