Samsung Expands One UI 9 Beta to Galaxy S25 and Z7 Series
The Android 17-based software preview now reaches older flagship models after an initial S26 rollout.
Samsung has expanded its One UI 9 Beta program to a wider array of flagship devices, bringing the latest Android 17 features to the Galaxy S25 series, Galaxy Z Fold 7, and Galaxy Z Flip 7. The rollout marks the next phase of the company's software testing cycle for its 2025 and 2026 hardware.
The expanded beta program is currently available to users in select global markets, including the United States, the United Kingdom, South Korea, and India. According to confirmed reports from the Samsung Newsroom, SamMobile, and Android Police, the One UI 9 beta initially launched exclusively for the Galaxy S26 series before the company opened enrollment to the previous generation S25 and Z7 foldable devices.
The Software Cycle
Samsung typically aligns its One UI releases with Google's annual Android deployment. The transition to One UI 9 represents the company's shift toward Android 17, following the established pattern of providing early access to power users and developers to refine stability before a wide public release. By including the S25 and Z7 series in this phase, Samsung ensures that its most recent legacy hardware is optimized for the new OS architecture.
Industry Implications
This expansion underscores Samsung's commitment to a rapid update cadence for its premium ecosystem. By bridging the gap between the S26 and S25 series so quickly, Samsung maintains a competitive edge in software longevity, a key selling point in the high-end smartphone market. For users, this means access to Android 17's core API changes and Samsung's proprietary interface enhancements months before the stable build reaches the general public.
What to Watch
As the beta progresses, the industry will be watching for specific stability improvements and new feature sets tailored for the Z Fold 7 and Z Flip 7's foldable displays. While the program is now live in the four primary markets, it remains unclear when the beta will expand to additional regions or if further legacy devices will be added to the testing pool before the final stable release of One UI 9.
