Samsung Japan details October and November One UI 9 rollout for 40 phones

Samsung has established a specific timeline for the distribution of its next major software iteration to a defined group of mobile devices in its Japanese market. The company released an official schedule detailing when 40 specific Galaxy smartphones and tablets will receive the One UI 9 update, which is built on the Android 17 operating system. This announcement follows the initial debut of the software on the Galaxy S26 series in September 2026, which also marked the beginning of the rollout for previous generation models.

The schedule published by Samsung Japan covers a wide range of hardware, including high-end flagships, foldable designs, mid-range smartphones, and various tablet configurations. Among the flagship phones listed are the Galaxy S26, S26+, S26 Ultra, S25, S25 Ultra, S24, S24 Ultra, S24 FE, S23, and S23 Ultra. The foldable category includes the Galaxy Z Fold 7, Z Flip 7, Z Fold 6, Z Flip 6, Z Fold 5, and Z Flip 5. Mid-range phones on the list consist of the Galaxy A57, A55, A54, A36, and A25. The tablet roster comprises the Galaxy Tab S11 and S11 Ultra, Tab S10 series, Tab S9 series, Tab S6 Lite (2024), Tab A11 series, and the Tab Active 5 Pro.

While the specific dates apply strictly to the Japanese region, the list of eligible devices is expected to serve as a reference for the global rollout. The company stated that the updates will arrive in Japan across October and November 2026. Industry observers anticipate that the global distribution will extend beyond this period, with many entry-level devices potentially receiving the software through December and January. The schedule does not include every possible candidate, omitting some "Plus" versions of recent Galaxy S flagships and numerous Galaxy A models sold in other territories.

Samsung began rolling out One UI 9 in September 2026, initially targeting the latest Galaxy S26 series. Since then, the update has reached a number of devices from the previous generation. The company is expected to continue the global rollout, with the pace of distribution likely to slow for lower-tier hardware as the year progresses. The official list provides a concrete framework for owners to determine their specific update window, although exact dates for individual models within the October and November period were not specified in the initial announcement.

The rollout of One UI 9 represents the next phase in Samsung's software support cycle, bringing the new Android 17 features to a broader segment of its user base. The inclusion of devices from multiple generations, including the Galaxy S23 and Tab S9 series, indicates that the company is maintaining support for hardware released several years ago. The specific timing for Japan offers a preliminary indicator of the global schedule, though regional differences in server load and carrier approval may cause variations in release dates outside the country.
