Samsung’s next major Galaxy software generation is One UI 9, built on Android 17. It first appeared as a beta for the Galaxy S26 series in May before arriving on Samsung’s newest foldable phones.
Samsung officially says One UI 9 will expand to more Galaxy devices as the rollout continues. For eligible owners, it is delivered as a software update rather than requiring them to buy a new phone.
The biggest new development concerns the Galaxy S25, S25+ and S25 Ultra. A fresh internal One UI 9 build was spotted on Samsung’s servers this week, following earlier evidence that the S25 beta was approaching.
The latest build reportedly follows Google Play Protect certification of an earlier test version. Forbes describes Samsung as apparently conducting final checks before opening the S25 public beta programme.
The Galaxy S24 family is not being left behind. New One UI 9 beta firmware has also appeared for the generation launched in 2024, showing that development has progressed beyond very early internal experimentation.
There is still no confirmed public beta date from Samsung for the S24 series. The evidence currently indicates progress towards one, rather than proof that the stable update is about to arrive immediately.
Samsung is also testing One UI 9 software for the Galaxy S25 FE. A new build appeared alongside those for the S24, S25 and S26 families, strengthening expectations of a broader beta expansion.
Previous reporting has suggested the S25 FE could participate in testing in markets including the UK. Until Samsung formally announces availability, however, individual countries and dates should be treated as provisional.
Galaxy S26 owners have had access to the One UI 9 beta in the UK since May through Samsung Members. Samsung officially launched the programme first on the S26 series.
Samsung is now preparing what appears to be a sixth beta build, placing the S26 family much closer to a stable update than older Galaxy generations currently entering the testing pipeline.
One UI 9 is not merely unfinished software. Samsung introduced it commercially with the Galaxy Z Fold8 Ultra, Galaxy Z Fold8 and Galaxy Z Flip8, announced on July 22, 2026.
Those devices officially went on sale in Europe on August 7. Their release gives Samsung a finished One UI 9 foundation that can now be adapted for more conventional Galaxy phones.
Among the confirmed changes;
A redesigned Quick Panel. Samsung says users gain greater control over its layout, with brightness, sound and media-player controls independently adjustable in size.
The interface also brings broader usability changes, including revised menus and navigation, while Samsung’s foldables gain additional multi-window and screen-layout improvements.
One UI 9 introduces Now Nudge, which can suggest a logical next action based on what the user is doing — such as opening Calendar when a conversation involves making plans.
Samsung is also adding voice-driven Photo Assist and My FanCam, which can take a wider recorded scene and later create a subject-focused crop inside Gallery.
Samsung says One UI 9 strengthens protection against suspicious applications. Its security system can warn users about newly identified high-risk apps, block execution or installation and recommend deletion.
Accessibility improvements include adjustable Mouse Keys, an updated combined TalkBack package and Text Spotlight, which can display selected text more clearly in a floating window.
Samsung warns that feature availability can vary by device, country, language and carrier. AI capabilities in particular may differ between newer flagships and older or less powerful models.
There is also no single confirmed date when every eligible Galaxy phone will receive stable One UI 9. What has changed is the evidence: testing is now spreading across several major device families, making the wider rollout considerably closer than it was only weeks ago.
