Samsung One UI 9.0 Testing Expands to 49 Devices: Full List Revealed

Samsung is accelerating the development of its upcoming software update, with internal testing for One UI 9.0 now underway across 49 smartphones and tablets. While public beta access remains strictly limited to the flagship Galaxy S26 series, official test servers indicate that the Korean tech giant is casting a wide net that includes older flagships, mid-range handsets, and budget-friendly devices.

Although an internal test build does not guarantee that a specific device will enter the public beta program or receive the stable release ahead of schedule, it is a strong indicator of Samsung’s rollout strategy. The company routinely begins software testing weeks or even months in advance to identify platform bugs and streamline optimization. This preparatory groundwork is what typically allows Samsung to rapidly deploy stable updates across its extensive product lineup once the software officially launches.

For Galaxy owners, having a device on the internal testing roster suggests that its respective One UI 9.0 development is actively progressing, increasing the likelihood of a timely—or potentially early—stable release.
