One UI 8.5 Update Status
Samsung is getting its new hardware products and software stuff ready ahead of the February 25 Unpacked. One UI 8.5 update rollout is linked to the Galaxy S26 series and the present status is pretty much confusing for the S25 series.
One UI 8.5 Beta Program was released in early December 2025. Samsung rolled out three Beta builds to the Galaxy S25 series so far. Work on the fourth Beta is underway, but the Stable build is also getting tested internally.
One UI 8.5 Beta
On February 4, Samsung uploaded two internal Beta builds to its software server. As per the findings, the latest build ends with ZZB3, via TarunVats. If verification goes well, it is expected to be provided to users as Beta 4 next week.
One UI 8.5 Stable
Beyond Beta, Samsung is also testing a Stable One UI 8.5 update. US models of the Galaxy S25 series are preparing the CZB3 build. It’s a non-Beta software, which would be provided to users as part of the update’s public rollout.

That said, the status of the One UI 8.5 update is confusing. The company is progressing with both the Stable and Beta builds internally. However, the official rollout may not kick off before the Galaxy S26 series goes on sale.
Samsung’s One UI 8.5 introduces notable user interface tweaks. It also expands the Galaxy AI feature suite to benefit Galaxy users. Transition effects and animations have also been improved to elevate Galaxy experiences.
Meanwhile, the Korean tech giant is bringing some serious upgrades to the Galaxy S26 series. Features like Privacy Display and improved night photo and video camera that rely on hardware may not be provided with updates.
