Samsung just skipped past the Galaxy S26 fans waiting in line and dropped something they probably weren’t expecting today. The stable One UI 9.0 update is officially rolling out to the Galaxy S25 series, making it the second Samsung lineup to get the full Android 17 treatment after the S26.
According to SamMobile, Samsung has ended the One UI 9.0 beta program for the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra, and pushed out the stable build in South Korea. Beta testers there can grab it now, and regular users in the country should see it roll out later today. The firmware version is S93xNKSUCDZIF and the download weighs in at around 500MB, which is pretty reasonable for a full OS update.
For everyone outside of South Korea, the timeline is a bit fuzzy. Samsung is expected to push the update to other regions later this week or into next week, depending on where you are. That’s pretty standard Samsung rollout behavior, so don’t panic if your phone hasn’t pinged you yet.
This matters because One UI 9.0 is built on Android 17, and that’s a meaningful step up. Samsung’s Galaxy S25 lineup already had strong software support promises attached to it when it launched, and seeing the stable update arrive this quickly shows the company is taking that commitment seriously. It also puts a bit of pressure on other Android makers to keep pace.
If you’re a Galaxy S25 series owner who signed up for the beta program, here’s how to check for the update right now:
- Open the Settings app on your Galaxy S25, S25+, or S25 Ultra
- Scroll down and tap “Software update”
- Tap “Check for updates” and let it do its thing
If you didn’t join the beta, just sit tight. Your turn is coming, and honestly, waiting for the stable build is almost always the smarter move. Beta software exists for a reason, and that reason is finding the bugs before they reach the rest of us.
The bigger picture here is that Samsung’s update cadence for its flagship phones has genuinely improved over the past few years. Getting a major OS update rolled out this smoothly, without a messy extended beta period, is exactly what Galaxy fans have been asking for. So far, so good.
