The wait for Samsung’s One UI 8.5 is almost over—at least for beta testers. Although Samsung hasn’t officially announced anything yet, a new leak spills the beans on when and where the beta rollout will begin.
If you’re a Galaxy user, especially from the S25 or upcoming S26 series, you’ll want to keep your eyes on this one. From new AI-powered notifications to advanced battery-saving tools, One UI 8.5 looks like a major upgrade.
Timeline
According to a leak shared by tech insider Tarun Vats on X (formerly Twitter), the beta rollout for One UI 8.5 is set to begin on December 8, 2025. Here’s how the rollout will reportedly unfold:
| Beta Phase | Rollout Date | Regions Covered |
|---|---|---|
| Beta 1 | December 8, 2025 | US, UK, South Korea, Germany |
| Beta 2 | December 22, 2025 | India, Poland |
| Beta 3 | January 5, 2026 | Global expansion or additional refinements |
While these dates aren’t official, leaks like these have often been accurate in the past. The beta updates will likely be available via Samsung’s Members app.
Devices
One UI 8.5 is expected to be first available on the Galaxy S25 series, as test builds have already been spotted on Samsung’s servers. Firmware versions such as S938NKSU7ZYKP and others have confirmed internal testing.
The stable version of One UI 8.5 is expected to debut with the Galaxy S26 series, which is tipped to launch by late January 2026. This means the beta rollout acts as a testing ground before the final release.
Features
Samsung isn’t just pushing a routine update. One UI 8.5 is expected to introduce several new and AI-enhanced features to improve both performance and user experience.
Network Battery
A new Network Battery Saver feature could help extend battery life by limiting background network activity during idle times. This might be especially useful for those who are constantly on the move or use their phones heavily throughout the day.
Pro Presets
Photographers and mobile creators are in for a treat. One UI 8.5 is rumored to bring Pro camera presets, allowing users to save and switch between custom camera settings easily—similar to how DSLR users manage shooting profiles.
Priority Alerts
Perhaps the most exciting addition is Priority Notifications powered by Galaxy AI. This feature could intelligently sort notifications, placing important ones (like messages from frequent contacts or urgent app alerts) at the top.
Even better, Samsung may allow users to manually select which apps are allowed to send high-priority notifications, giving you full control over what really deserves your attention.
Availability
Initially, only a handful of regions will get access to the beta, but Samsung usually expands these over time. Here’s a quick look at the expected order of availability:
| Region | Beta Phase |
|---|---|
| US | 1 |
| UK | 1 |
| South Korea | 1 |
| Germany | 1 |
| India | 2 |
| Poland | 2 |
If you’re in one of these regions and have a compatible Galaxy device, you’ll be able to sign up for the beta via the Samsung Members app.
Expectations
Even though it’s a “.5” update, One UI 8.5 feels more like a prelude to One UI 9.0. It’s adding smarter notifications, deeper AI integration, and helpful tools for battery and camera performance. Plus, if you’re planning to buy the Galaxy S26, you’ll be among the first to experience it out of the box.
As with any beta software, expect bugs, but also expect to see where Samsung is heading in terms of user experience.
With the official announcement likely coming soon, the leak has given us a pretty good idea of what to expect. If you’re into early access and don’t mind a few glitches, December is looking pretty exciting.
