Samsung’s One UI 8 Starts Rolling Out: What Galaxy Owners Get Now—and When the U.S. Follows

Samsung has begun the stable One UI 8 rollout, starting with the Galaxy S25 series in select regions and expanding to more devices in October.

Samsung has started pushing out One UI 8, its next major Android-based software update, beginning with the Galaxy S25 series in select markets. The company says more Galaxy phones and tablets-including the S24 line and recent foldables-are slated to receive the update in October, with regional timing to vary by carrier and device. The rollout began in Korea and parts of Europe, and U.S. builds are expected to follow once carrier approvals wrap.

This release is about polish over spectacle. One UI 8 refines Quick Share, improves DeX scaling and rotation, streamlines split-screen handling, refreshes Samsung Internet, and tightens device security under the hood. Early hands-on notes mention iterative gains across media features and system tools, with more models joining the schedule into October. 

For U.S. owners, history suggests a short lag between global launch and carrier-approved builds. If you're on an S25 device, watch Settings → Software update over the next several days; S24-series users should look to October based on Samsung's stated plan. If you rely on DeX for work or frequent file sharing across ecosystem devices, One UI 8 will feel like a polish-heavy update-small gains that add up in daily use. 

Korea-related angle matters for supply and developer ecosystems: a clean rollout across S25 and S24 increases near-term installed base for app makers targeting Samsung's premium segment, while stable DeX and media pipelines support pro-workflows popular among creators in Seoul and U.S.-Korean communities.
