Samsung has published a Thailand rollout schedule for stable One UI 9, with the Galaxy S25 series, Galaxy Z Fold 7 and Galaxy Z Flip 7 set to receive the update on September 28. The company says the Galaxy S23 FE will follow by October 2026, although it has not provided a specific release date for that model.
The timetable follows Samsung’s initial stable One UI 9 release for the Galaxy S26 series in South Korea last week. Samsung Thailand lists September 21 as the Galaxy S26 series rollout date in Thailand.
- Galaxy S26 series — September 21 in Thailand
- Galaxy S25 series — September 28 in Thailand
- Galaxy Z Fold 7 — September 28 in Thailand
- Galaxy Z Flip 7 — September 28 in Thailand
- Galaxy S23 FE — by October 2026 in Thailand; no exact date announced
These dates have been officially confirmed only for Thailand, so timing may differ across other regions and carrier variants. Samsung has not yet published a broader regional rollout calendar for the models listed, leaving the next market-specific announcements as the key detail to watch.
