TL;DR
-
Samsung has quietly changed the Galaxy S26 series’ One UI 9 rollout date in Thailand from September 21 to September 28.
-
The new date puts the Galaxy S26 series alongside the Galaxy S25 series and Galaxy Z Fold 7, which were already scheduled for September 28.
-
Samsung hasn’t explained the change or announced a wider delay, so it’s unclear whether the revised date applies beyond Thailand.
Samsung’s One UI 9 rollout may have hit a small speed bump, at least for Galaxy S26 owners outside Korea. Samsung started rolling out the stable One UI 9 update to the Galaxy S26 series in Korea a few days ago, which usually means owners elsewhere don’t have to wait too long.
The company even gave a fairly specific date to look forward to. Samsung’s Thailand Newsroom previously listed September 21 as the rollout date for the Galaxy S26 series, followed by September 28 for the Galaxy S25 series and Galaxy Z Fold 7. September 21 has now passed, though, and Samsung appears to have quietly changed its plans.
