Samsung Accelerates One UI 9.0 Rollout; Galaxy S23 Series Next in Line After Newer Flagships
Samsung continues to push its One UI 9.0 update, based on Android 17, across its device ecosystem. After rolling out to its latest flagship models, attention is now turning to the popular Galaxy S23 series, which is expected to receive the significant software upgrade very soon. This update brings a host of new features and improvements designed to enhance user experience and device security.
One UI 9.0 Rollout: A Phased Approach
Samsung initiated the stable distribution of One UI 9.0 in mid-September. The update first reached the newest Galaxy S26 series, followed by the S25 and S24 models. This global rollout for the latest generation typically took around two weeks. Now, the focus shifts to devices released in 2023.
Galaxy S23 Series: The Next Stage
Recent reports indicate that the Galaxy S23 series is the next natural step in this rollout. For these phones, One UI 9.0 is expected to be the last major system update, similar to the Galaxy S22 series, which is unlikely to receive a 9.5 version. A prediction from October 9, 2026, by a user on X (formerly Twitter) suggested the update would arrive for the S23 series “next week”:
