Samsung’s One UI software continues to evolve, offering users enhanced features, deeper AI integration, and refined customization. The company’s latest iteration—One UI 8.5—has begun its beta life, but for many Galaxy owners the big question remains: when will the beta expand to more devices beyond the Galaxy S25 series? Here’s a deep dive into what we know so far, based on SamMobile’s coverage and Samsung’s historical rollout patterns.
One UI 8.5 Beta: The Launch So Far
Samsung officially kicked off the One UI 8.5 beta program in early December 2025, starting with the flagship Galaxy S25 lineup. This initial phase focused solely on the S25, S25+, and S25 Ultra, giving users in select regions the first taste of what’s next.
This initial beta has seen multiple revisions and updates as Samsung continues to refine the software before opening it up to a wider audience. For now, though, the beta remains exclusive to Samsung’s latest flagship devices—a familiar pattern that mirrors previous One UI beta releases.
Why the Hold-Up? Understanding Samsung’s Beta Strategy
To understand the timeline for expansion, it’s helpful to look at how Samsung handled beta testing for previous One UI versions. With One UI 7, the beta began on flagship models and didn’t expand to other devices until roughly three months after the initial rollout. Similarly, the One UI 8 beta stayed limited to flagship devices before gradually expanding to include foldables and other premium models.
If Samsung follows this established pattern, the first big wave of expansion for One UI 8.5 should arrive in late February or March 2026—around the time the next flagship lineup (like the Galaxy S26 series) launches. This would place the expansion just over two to three months after the initial beta debut.
Which Devices Are Most Likely to Join the Beta Next?
Based on Samsung’s past rollout behavior and the One UI device eligibility list, the following groups are prime candidates for the next phase of One UI 8.5 beta testing:
- Galaxy S24 series: Traditionally next in line after the latest flagship.
- Foldable devices like Galaxy Z Fold7 and Z Flip7: Samsung has a history of including its foldable lineup early in beta expansions.
- Older flagships: The Galaxy S23 and even devices further back may follow in later waves.
However, at least one report indicates Samsung might also be testing One UI 8.5 internally on other devices, including mid-range models like the Galaxy M15 and M36. While internal testing doesn’t guarantee public beta access, it signals that the software is being readied for broader deployment.
Stable Release Expectations
Samsung isn’t expected to release the final stable build of One UI 8.5 immediately alongside the beta expansion. According to industry forecasts, the stable version is likely to launch with the Galaxy S26 series in early 2026—potentially around late February or early March—and then trickle down to other eligible devices afterward.
This staged approach allows Samsung to drain feedback from beta testers, refine features, and fix bugs before a wider rollout. It’s also consistent with how previous One UI updates have been managed.
What to Expect in One UI 8.5
Beyond the timeline, users are eager to know what One UI 8.5 actually brings to the table. While the full stable changelog is still forthcoming, early beta builds have revealed a number of enhancements designed to improve usability and device intelligence. These include:
- Deeper AI integration and smarter suggestions
- Customizable Quick Panels
- Improved Galaxy AI tools for image editing
- Expanded features like Storage Share and enhanced connectivity
- UI refinements and support for Auracast audio
These updates aim to enrich the everyday user experience, making navigation smoother and offering smarter assistance across Samsung’s ecosystem.
Patience Is Key
For many Samsung fans, the wait for One UI 8.5’s wider beta rollout might feel long—but Samsung’s software testing and deployment strategy is methodical by design. By starting with flagship devices and gradually expanding, the company ensures a more stable and refined experience for a broader user base.
Based on historical timing and observed testing patterns, Galaxy S24 owners and users of Samsung’s newer foldables should see access to the One UI 8.5 beta by late March 2026—with older devices following soon after. Stay tuned for official announcements and new beta waves as Samsung continues to roll out its biggest One UI update yet.
