Samsung has pushed the stable One UI 9.0 update — based on Android 17, to Galaxy S25, S25+, and S25 Ultra users in Europe. The rollout began early Monday morning, local time, with firmware version S93xBXXUCDZIF. It follows limited beta testing and precedes wider availability: South Korea got it last week. The US received it yesterday. More regions are expected to follow later this week. This is not a phased global launch. It’s regional, staggered, and already live for some. The update is currently landing first for users who opted into the One UI 9.0 Beta Program. For them, it’s a 550MB download. Samsung says the full public rollout starts later today, with a larger 3GB+ package. No India, UK, or Middle East rollout date is confirmed yet. No price change. No hardware revision. Just software, and it’s here now for select S25 owners in Europe. To install: Settings > Software update > Check for updates. Samsung recommends at least 30% battery and a backup before proceeding. One UI 9.0 brings Android 17’s core underpinnings. Including new privacy controls, background activity limits, and updated notification handling, plus Samsung’s own layer of interface tweaks, gesture refinements, and camera pipeline improvements. Full feature details are linked from SamMobile’s report, but Samsung hasn’t published its own official changelog yet. This isn’t the first major OS update for the S25 series. But it is the first stable Android 17 build officially certified and shipped by Samsung. And it arrives just over eight months after the S25 launched globally. Next: watch for the update hitting the UK and India within 48–72 hours, per Samsung’s typical regional cadence. Then the rest of Asia-Pacific, Latin America, and Africa follow, likely through October’s second week.
