- Samsung’s stable One UI 9 update is rolling out to Galaxy S24-series users in the US.

Samsung’s One UI 9 rollout has been steadily working its way backward through the company’s flagship lineup. After reaching the Galaxy S26 and S25 families, Samsung turned its attention to the Galaxy S24 series, Galaxy Z Fold 6, and Galaxy Z Flip 6 in South Korea last week. We expected other markets to follow soon, and that expansion is now underway.
Stable One UI 9, based on Android 17, has begun rolling out to Galaxy S24-series owners in the US, with users reporting the update on both T-Mobile and AT&T devices. The rollout is also spreading beyond the US, with reports that the update has arrived in India and other markets.
