A Samsung Members community post published September 28 reported that non-beta Galaxy S25-series users in South Korea were receiving the stable One UI 9 update. The post cited build S938NKSUCDZIF. One UI 9 is based on Android 17, and Samsung’s broader rollout is expanding gradually.
One UI 9 reaches non-beta Galaxy S25 users in South Korea
The September 28 post reported the stable update for Galaxy S25-series owners in South Korea who had not joined the beta. That is a report of availability in one market, not a rollout to every S25 owner worldwide.
Updates for older Galaxy models were described as arriving in stages, with some early stable releases reaching people who had participated in the beta first. A forecast put the U.S. arrival within about a week of the South Korean S25 rollout.
Samsung began its stable rollout with the Galaxy S26 series
Samsung announced on September 16, 2026, that the stable One UI 9 rollout had begun with the Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra. Samsung said it would expand gradually to more Galaxy devices.
In Spain, a September 29 rollout report covered the Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra. That account concerned the S26 family.
What One UI 9 brings to Galaxy phones
One UI 9 is Samsung’s Android 17-based interface. Samsung lists My FanCam, Now Nudge, editable Now Brief cards, Interpreter Thread View, document-scanning improvements, Security Brief, and Privacy Alerts among its features. Samsung specifically lists Privacy Alerts support for Galaxy S25. Availability of features can vary by device, country, region, language, carrier, and account.
