One UI 9 for Galaxy S25 Ultra in India: Rollout Status and Update Steps

Samsung’s One UI 9 update, built on Android 17, reached Galaxy flagship users in late September 2026, but availability differs between the Galaxy S25 and S26 series. For Indian users searching one ui 9 s25 ultra, the key point is that a search spike does not mean every S25 Ultra in India has received the stable update.

Galaxy S25 Ultra: where the rollout stands

GSMArena reported on September 28, 2026 that Galaxy S25, S25+ and S25 Ultra users in Korea had received the stable One UI 9 notification, including users who were not in the beta program. The reported build for the S25 series is S938NKSUCDZIF, a 3.9GB download. The report said users in the US should expect the notification the following week if the S26 timing pattern repeats. It did not confirm a stable India release for the S25 Ultra on that date. Read GSMArena’s report.

Galaxy S26 Ultra: India beta access confirmed

SamMobile reported on September 29, 2026 that Samsung had started rolling out stable One UI 9.0 for the Galaxy S26 series outside South Korea and the US. The update was available for beta testers on the Galaxy S26, S26+ and S26 Ultra in India and Europe, carrying the September 2026 security patch and firmware version S94xBXXU4BZI6. A wider release may follow, though some regions could wait until October. Read SamMobile’s report.

How to check for the update

Open the Settings app, scroll to Software update, and tap Check for updates. Samsung advises keeping at least 30% battery charge and backing up important data before installing.
