Samsung One UI 9 refers to the next major software platform upgrade from Samsung, expected to be based on Android 17. A development build has surfaced for the Galaxy S26 Ultra, offering the first public screenshots of the interface and signalling that active work on this upgrade is already well underway.
TL;DR: The first Samsung One UI 9 build has appeared on a Galaxy S26 Ultra test device, revealing a more refined pill-shaped UI, a redesigned browser with three layout options, a rumoured Ask AI button, and glassy visual effects. The Galaxy S26 Ultra itself ships with One UI 8.5, not One UI 9.
What does the Samsung One UI 9 design actually look like?
The most immediately visible change in Samsung One UI 9 is a more compact, pill-shaped floating bottom bar replacing the rectangular tab design used in One UI 8.0. Compared to the incremental refinement seen in One UI 8.5, the new bar looks noticeably cleaner and more considered — it’s a small change that makes a real difference to how apps feel at a glance.
The screenshots show this redesign most clearly in apps like Quick Share, where the bottom navigation has shed its blocky appearance in favour of rounder, more floating elements. Samsung has attempted pill-shaped UI elements before and quietly rolled them back, so it’s worth watching whether this direction sticks through to a public release.
Beyond the navigation bar, One UI 9 is expected to bring glassy visual effects, translucent layers, and blur effects to the broader interface — an aesthetic direction that echoes what Google has been doing with its Pixel system UI for some time. Whether Samsung executes this with the same restraint remains to be seen.
Samsung One UI 9 browser: three layouts and an AI button
The Samsung Internet browser in One UI 9 reportedly introduces three customisable layout options: Standard (the classic layout), Bottom (optimised for one-handed use), and Compact, which features a floating search bar with a fade-in/out animation on scroll. That Compact mode is the most interesting of the three — it keeps the interface out of the way until you actually need it.
The Compact layout also reportedly includes a rumoured Ask AI button, potentially powered by Perplexity AI integration. If real, this would let users get contextual responses without leaving the page they’re browsing. It’s a genuinely useful idea, though it remains unconfirmed at this stage and should be treated with appropriate scepticism until Samsung makes an official announcement.
AI features expected in One UI 9
On-device AI improvements are a central part of what One UI 9 is expected to deliver. The development build points toward enhanced photo editing powered by on-device AI, text summarisation, and predictive actions that anticipate what a user needs before they ask. Samsung is also expected to tighten Galaxy ecosystem workflows, including a universal clipboard and synchronised Do Not Disturb settings across devices.
Granular notification and privacy controls are also on the list of expected improvements, alongside battery efficiency gains. These are areas where Samsung has faced consistent criticism compared to stock Android, and One UI 9 appears to be addressing them directly — though the specifics remain tied to pre-release builds rather than confirmed feature sets.
Galaxy S26 Ultra and One UI 8.5: what ships now
It’s worth being clear about timing: the Galaxy S26 Ultra ships with One UI 8.5, not One UI 9. Buyers getting the device today are getting Samsung’s current software generation, which includes Now Brief for contextual reminders, Now Nudge for intelligent suggestions, and AI Select. One UI 9 is a future upgrade, and no official launch date has been confirmed.
The Galaxy S26 Ultra’s hardware — a 6.9-inch Dynamic AMOLED 2X display with peak brightness of 2600 nits, improved mDNIe image processing with 4x precision, and ProScaler for sharper visuals — will eventually run One UI 9. That hardware foundation makes it a strong candidate to showcase whatever visual refinements One UI 9 ultimately delivers.
Compared to Google’s Pixel UI approach, which separates quick settings and notifications into distinct swipe gestures and has long used pill-shaped status icons, Samsung‘s One UI has historically leaned heavier and more feature-dense. One UI 9 appears to be borrowing some of that visual restraint, which is a welcome direction even if the execution won’t be confirmed until a beta programme launches.
When will Samsung One UI 9 release?
No official release date for Samsung One UI 9 has been announced. The appearance of a development build on the Galaxy S26 Ultra confirms that engineering work is active, but pre-release builds can look very different from final software. Samsung typically runs public beta programmes ahead of major One UI releases, which is when the picture will become much clearer.
Will the Galaxy S26 Ultra get One UI 9?
Yes, the Galaxy S26 Ultra is expected to receive One UI 9 as a future software update, given that the first development build has appeared on that very device. Samsung’s flagship devices have historically been among the first to receive major One UI upgrades. The S26 Ultra currently ships with One UI 8.5.
How is One UI 9 different from One UI 8?
One UI 9 introduces a more compact pill-shaped bottom navigation bar, replacing the rectangular tabs used in One UI 8.0 and refining the design from One UI 8.5. It is also expected to bring a redesigned browser with three layout modes, deeper on-device AI integration, glassy visual effects, and improved privacy controls — representing a more substantial visual and functional shift than the 8.0 to 8.5 step.
Samsung One UI 9 is still early in its development cycle, and pre-release builds are exactly that — pre-release. But the direction is encouraging. The pill-shaped UI, the browser overhaul, and the AI integrations all point toward a Samsung software experience that’s finally willing to prioritise clarity over feature density. Whether that ambition survives the journey to a public release is the question worth watching.
