Subscribe to our newsletter The first build of One UI 9 has appeared We also have screenshots from the software Expect a launch sometime later in 2026 We haven't yet seen a wider rollout of the One UI 8.5 software that made its debut on the Samsung Galaxy S26 phones (unveiled at the end of February), but it seems progress is being made on One UI 9 too as the first build of the update has just shown up.

As tipster Tarun Vats reports, there is now an official One UI 9 build on Samsung 's servers and the folks at SamMobile have been able to get it up
and running on a phone. It's an important milestone in the development of any Android update, and worth noting. The same source goes on to say that development will follow the same timeline as we saw last year with One UI 8 (based on Android 16). You may remember that after months of beta testing, it launched in July 2025 with the Galaxy Z Fold 7 and Galaxy Z Flip 7.

Older phones started to get One UI 8 from September 2025 , so expect the same sort of cadence throughout 2026. It may not be too long before a One UI 9
beta program opens up (though you'll probably need a newer Samsung phone to access it). Here's what's coming BREAKING The first internal One UI 9 test build for the Galaxy S26 Series has been spotted on the server today. Build Version:S948BXXU1BZC5/S948BOXM1BZC5/ S948BXXU1BZC5Samsung has officially started One UI 9 development,following same timeline as last year.Repost pic.twitter.com/1DyxBLb2X4 March 16, 2026 At this early stage, the
screenshots shared by SamMobile don't show much in the way of chances, but we know One UI 9 is going to be based on Android 17 , and so that gives us some clues about what might be coming down the pipe with this major update.

Android 17 is already in beta testing on Pixel phones, and there are some interesting upgrades on the way: better support for lock screen widgets and app windowing for example, as well as improvements to how Android looks on less typical screen sizes.

It also seems as though Android 17 will support an iOS-like notification tweak, which means you'll be able to swipe down from the top left corner to show your notifications, and swipe down from the top right corner to show the Quick Settings.

No doubt there's more to come with Android 17 ahead of its grand unveiling at Google I/O 2026 in May as the Android 17 beta program continues. As usual, Samsung will apply its own tweaks and enhancements on top of Google 's codebase as well.
