Samsung has officially started rolling out the One UI 8.5 Beta 5 update for the Galaxy S25 series, signaling that the stable release is just around the corner.
This could be the final beta build before Samsung unveils the stable version of One UI 8.5, which is expected to debut later this month.
One UI 8.5 Beta 5 Now Live in Multiple Regions
The new beta update is already available in several markets. While it’s labeled as Beta 5 in most regions, users in India are reportedly receiving it as Beta 4, as it is the fourth beta build released there.
The firmware version ends in ZZAN, confirming it as the latest test build ahead of the public rollout.
Based on Android 16 QPR2
One UI 8.5 Beta 5 is built on Android 16 QPR2, which Google recently rolled out to eligible Pixel phones. Samsung is now integrating the same base with its custom One UI enhancements for Galaxy users.
The update package comes in at 553.08MB, making it a relatively small but important refinement build.
What’s New in One UI 8.5 Beta 5?
While this beta doesn’t introduce major new features, it focuses on refinements and system stability. The changelog highlights:
- Applied Bixby version update
- System optimizations
- Various bug fixes and performance improvements
As expected with late-stage beta builds, Samsung appears to be polishing the experience rather than adding new functionality.
How to Install the Update
If you’re enrolled in the beta program on the Galaxy S25 series, you can install the update by:
Settings > Software update > Download and install
We recommend installing the update once prompted to ensure you’re running the latest optimized build before the stable release.
Stable One UI 8.5 Launching with Galaxy S26 Series
The stable version of One UI 8.5 is expected to debut with the upcoming Galaxy S26 series during Samsung’s February 25 Unpacked event.
With the stable rollout so close, it’s unlikely that additional Galaxy models will join the beta program at this stage. Instead, Samsung is expected to move directly to a stable rollout for eligible devices after the official announcement.
We expect more clarity following the Unpacked event.
Final Thoughts
One UI 8.5 Beta 5 appears to be a polishing update aimed at delivering a smooth and stable experience ahead of the official launch. If this is indeed the final beta build, Galaxy S25 users won’t have to wait much longer for the stable version.
Stay tuned for more updates as Samsung prepares for its next big software release.
