Samsung is accelerating the development of its One UI 9 operating system, with internal testing now spanning four generations of flagship smartphones and select mid-range devices. According to firmware tracker Tarun Vats, the company is conducting simultaneous builds for the Galaxy S23, S24, and S25 series, alongside the Galaxy S24 FE and the Galaxy A56, as it prepares for an upcoming product launch.
Which devices are currently eligible for One UI 9 testing?
The One UI 9 beta program is currently active across a wide range of hardware, with different levels of development occurring for each model. Firmware data confirmed by Tarun Vats indicates that the Galaxy S26, S26+, and S26 Ultra are currently in an active public beta phase. Meanwhile, internal testing is underway for the Galaxy S25 series (including the S25 Edge), the Galaxy S24 lineup, the Galaxy S24 FE, the Galaxy S23 series, and the Galaxy A56. The Galaxy Z Fold 8 Ultra, Z Fold 8, and Z Flip 8 are expected to ship with a stable version of the software on July 22.

Samsung’s “agentic AI” features, expected to debut with the Galaxy Z Fold 8, are designed to perform multi-step tasks autonomously, such as booking concert tickets or managing email responses without constant user intervention.
What improvements does the latest beta include?
The most recent build, Beta 3, focuses primarily on system stability and resolving performance bugs identified in earlier testing. According to Samsung’s release notes, the update addresses camera preview cropping issues, lock screen widget errors, and S Pen input bugs that previously caused home screen swipe failures. The update also includes a fix for random reboots that occurred during video streaming. Additionally, Samsung has introduced a “Summarise Notifications” feature in the Quick Panel, which the company explicitly labels as AI-generated to maintain transparency with users.

How does One UI 9 compare to previous update cycles?
Samsung is moving significantly faster with its One UI 9 rollout compared to the timelines observed in previous years. By managing development across four generations of flagships simultaneously, the company aims to reach a stable build before the upcoming Unpacked event in London. While last year’s updates were often siloed by device age, the current approach treats the S23, S24, and S25 as part of a unified deployment pipeline. This strategy suggests a shift toward modular software architecture, allowing Samsung to deploy core fixes—such as the animation smoothing seen in Beta 3—across a broader device footprint at once.
