Samsung is ramping up the software deployment schedule for its primary line of flagship devices. Following initial regional testing and early rollouts, the stable One UI 9 update—built on top of Android 17—is expected to expand significantly between October 5 and October 9, 2026.
Whether you are carrying the current generation of Galaxy flagships or last year’s premium models, here is what is landing on Samsung devices across international markets and in South Korea this week. You can monitor every regional release and build phase in real time on our comprehensive Samsung One UI 9 Android 17 Global Update Tracker.
One UI 9 Stable Global Rollout
For global users holding Samsung’s flagship hardware, the wait for a final, stable build of One UI 9 is drawing to a close. Samsung is prioritizing its lineup of non-foldable and current-gen foldable devices worldwide.
Expected Global Devices (October 5–9):
Galaxy S25 Series (Galaxy S25, Galaxy S25+, Galaxy S25 Ultra)
Galaxy Z Fold7
Galaxy Z Flip7
Users in international regions—including North America, Europe, India, and Southeast Asia—can look for Over-The-Air (OTA) update notifications this week. The stable release brings system-wide performance improvements, refined quick-panel layouts, and expanded Galaxy AI capabilities to the 2025–2026 flagship tier.
Carrier rollouts are also picking up speed alongside unlocked variants; for instance, US carrier variants are rapidly following the broader rollout timetable, as seen in recent carrier deployments like the Samsung Galaxy S26 One UI 9 Stable Rollout on T-Mobile.

One UI 9 Stable South Korea Rollout

Expected Domestic (Korea) Devices (October 5–9):
Galaxy S24 Series (Galaxy S24, Galaxy S24+, Galaxy S24 Ultra)
