Samsung Japan schedules One UI 9 for 40 devices in Q4
The rollout covers S23 through S26 flagships, foldables, and mid-range tablets, with global timing expected to extend into early 2027.

Samsung Japan has assigned specific delivery dates for its One UI 9 operating system update across 40 distinct Galaxy models. The software, built on Android 17, will begin reaching these devices in Japan during October and November 2026. While the schedule is region-specific, the device list serves as a proxy for the global rollout, which is expected to follow a similar trajectory.
The update queue is heavily weighted toward recent hardware. Flagship smartphones include the Galaxy S26, S26+, S26 Ultra, S25, S25 Ultra, S24, S24 Ultra, S24 FE, S23, and S23 Ultra. Foldable devices on the list comprise the Galaxy Z Fold 7, Z Flip 7, Z Fold 6, Z Flip 6, Z Fold 5, and Z Flip 5. These models were among the first to receive the software when One UI 9 launched in September.
Mid-range phones and tablets make up the remainder of the roster. The smartphone list includes the Galaxy A57, A55, A54, A36, and A25. The tablet lineup is extensive, covering the Tab S11 series, S10 series, S10 FE series, S10 Lite, S9 series, S9 FE series, Tab S6 Lite (2024), Tab A11, Tab A11+/5G, and Tab Active 5 Pro. This breadth indicates a push to standardize the user interface across a wide range of price points and form factors.
The official list is not exhaustive. Notable omissions include the "Plus" variants of recent Galaxy S flagships and numerous Galaxy A models sold in specific markets. This suggests that the initial batch represents the primary tier of support, with secondary waves of updates likely to follow for less prominent SKUs.
Samsung expects the global rollout to extend beyond the Japanese timeline. Many entry-level devices are projected to receive the update through December 2026 and January 2027. The company has not published a single unified global calendar, meaning users in other regions should monitor local carrier or carrier-specific release notes for precise installation times.
The rollout strategy mirrors previous annual update cycles, where flagship devices receive patches within months of the launch event. By locking in dates for 40 models, Samsung provides a clearer timeline for consumers who have been waiting for the transition from One UI 8 to the new Android 17-based interface.
