After testing preview builds exclusively on the flagship Galaxy S26 series since May, Samsung is broadening its software development cycle to encompass previous-generation premium hardware. The South Korean tech giant confirmed that its Android 17-based One UI 9 beta is officially open to the Galaxy S25 family alongside last year’s foldable handsets across select global testing markets. The expanded deployment signals that foundational system stability has matured, allowing registered enthusiasts to test overhauled visual shaders, predictive system-level widgets, and tighter app permissions before the final software update rolls out to millions of mainstream Galaxy owners worldwide.

One UI 9 BETA: Expanded hardware eligibility and availability
The newest phase of the One UI 9 beta incorporates Samsung’s high-end portfolio from the past generation, extending testing access to the Galaxy S25, Galaxy S25+, Galaxy S25 Ultra, and the Galaxy S25 FE. Owners of the Galaxy Z Fold7 and Galaxy Z Flip7 are also included in this rollout wave.
Testing is currently live across key regional corridors, specifically India, the United States, the United Kingdom, and South Korea. Eligible users can register their devices directly through interactive promotional banners hosted inside the Samsung Members app to pull over-the-air installation packages.

One UI 9 BETA: Privacy protections and visual overhauls
On the security side of things, One UI 9 deploys a dedicated status bar location indicator alongside system sandboxing alerts designed to identify high-risk background applications. The interface also benefits from upgraded background blur shaders, smoother Quick Panel animations, customizable lock screen audio visualizers, and persistent network speed meters.
Expanding One UI 9 to previous-generation flagships highlights Samsung’s accelerated software deployment pipeline. Rather than trapping Android 17 on the newest hardware while competitors prepare fall updates, broadening the test pool ensures rapid bug resolution across diverse display formats and processors. For Galaxy S25 users, the release offers a functional preview of refined UI utilities, though casual owners should carefully weigh the risks of unoptimized beta software on daily driver devices.
