When will Samsung Galaxy S25 get the stable One UI 9 update?

If you’re using a Samsung Galaxy S25, chances are you’ve already started wondering one thing: when will One UI 9 finally arrive?

It’s a fair question. Samsung has already kicked off the One UI 9 public beta based on Android 17, but the program is currently exclusive to the new Galaxy S26 series. That doesn’t mean Galaxy S25 owners will be waiting much longer, though.

While Samsung hasn’t announced an official rollout schedule for last year’s flagship, the company has become remarkably consistent with its software update strategy over the past few years. Looking at that history gives us enough clues to make an educated prediction on when the Galaxy S25 could receive both the One UI 9 beta and the final stable release.

The Galaxy S25 is already testing One UI 9 behind the scenes

Before talking timelines, it’s worth noting that development is already underway. Samsung has already been spotted testing One UI 9 internally for the Galaxy S25 series, confirming that work on the Android 17 update is progressing well. Internal testing is typically one of the final stages before a device graduates to a public beta program. We’ve been tracking every development surrounding Samsung’s Android 17 rollout, including internal builds, beta expansions and stable releases, in our dedicated One UI 9 update tracker.

If you haven’t already, it’s worth bookmarking the page because we update it whenever another Galaxy device joins the One UI 9 journey, whether through internal testing, the public beta program or the stable rollout.

History suggests the Galaxy S25 beta could begin in August

Samsung may not publish an official roadmap months in advance, but it has developed a fairly predictable release pattern for its flagship phones. Last year offers perhaps the best comparison.

The Galaxy S24 series, which was Samsung’s previous-generation flagship at the time, joined the One UI 8 public beta in early August after the newer Galaxy S25 had already taken the spotlight earlier in May, just like this year’s Galaxy S26 series with the One UI 9 beta update. That beta program continued to September, which is when the stable One UI 8 update arrived for the Galaxy S24 before Samsung briefly paused the rollout to address bugs. The wider stable rollout resumed shortly afterwards in October.

This year, the Galaxy S25 occupies exactly the same position in Samsung’s lineup that the Galaxy S24 held a year ago. The Galaxy S26 is now Samsung’s newest flagship and the first device to receive the One UI 9 beta. If Samsung sticks to the same playbook, and it usually does, we expect the company to expand the beta to older premium devices sometime in August.

That expansion will include:

• Galaxy S25
• Galaxy S25+
• Galaxy S25 Ultra
• Galaxy Z Fold 7
• Galaxy Z Flip 7

The timing also makes sense from a product strategy perspective. Samsung typically gives its newest flagship a period of exclusivity before opening beta testing to previous-generation devices. That means the expansion should happen shortly after the Galaxy Z Fold 8 and Galaxy Z Flip 8 become widely available.

So when will the stable Galaxy S25 One UI 9 update arrive?

Assuming Samsung follows last year’s schedule, Galaxy S25 owners shouldn’t have to wait too long after the beta begins. My prediction is that the stable One UI 9 update based on Android 17 will begin rolling out to the Galaxy S25 series sometime between late September and early October. As always, the exact timing will depend on several factors, including:

• Your Galaxy S25 model
• Your country or region
• Whether your phone is carrier-locked
• Whether Samsung encounters significant bugs in the early stable rollout phase

Unlocked devices in Samsung’s primary rollout markets like the US, Germany, UK, and India often receive major updates before carrier variants and some regional models, so don’t be surprised if availability varies by a few weeks.

The Galaxy S25 has plenty of software life left

One UI 9 isn’t the end of the road for Samsung’s 2025 flagship. The Galaxy S25 series is eligible for seven generations of Android OS upgrades, making Android 17 and One UI 9 only the second major platform update for the device. That means owners can still look forward to several more Android releases over the coming years. It’s one of the biggest advantages of buying Samsung’s flagship phones today, because they remain relevant for years instead of just one or two Android versions.

But nothing is official until Samsung says so, though the company’s recent update history gives us a good idea of what to expect. If the rollout follows the same pattern as last year:

• August: One UI 9 public beta expands to the Galaxy S25 series.
• Late September to October: Stable One UI 9 begins rolling out to the Galaxy S25 family.
• Following weeks: Wider rollout reaches more regions and carrier variants.

Of course, software development doesn’t always go according to plan. A major bug or last-minute issue could shift Samsung’s schedule, just as we saw during last year’s One UI 8 stable rollout for the Galaxy S24.

Until then, the best way to stay on top of Samsung’s Android 17 rollout is by following our One UI 9 update tracker, where we document every new internal build, beta release, and stable rollout as they happen. If you’re waiting for One UI 9 on your Galaxy S25, bookmark that page and check back regularly. We update it whenever Samsung expands the rollout to another Galaxy device.

For now, all signs point to the Galaxy S25 joining the One UI 9 beta in August, with the stable update likely following a month or so later. If Samsung sticks to its now-familiar software release cadence, Galaxy S25 owners won’t have to wait much longer.
