Samsung One UI 9 is rolling out: is your Galaxy getting Android 17?

Samsung has started rolling out the stable version of One UI 9, beginning with the Galaxy S26 series. The update comes around three months after Android 17 first landed on Google Pixel phones on 16 June. And, thankfully, this isn’t just another update where the headline feature is that one menu has moved three pixels to the left.

One UI 9 brings new Galaxy AI features, more customisation, some genuinely useful security changes and a few quality-of-life upgrades.

Which Samsung phones are getting One UI 9 first?

There is a slightly confusing answer to this. Galaxy Z Fold8 Ultra, Z Fold8 and Z Flip8 were the first Samsung phones to launch with One UI 9 already installed. The newer Galaxy S26 FE also ships with Android 17 and One UI 9 out of the box.

For existing phones being upgraded, Samsung started with Samsung Galaxy S26, Samsung Galaxy S26+ and Samsung Galaxy S26 Ultra.

The rollout officially began on 16 September 2026, although availability varies by country, network and device.

Samsung has also opened its One UI 9 beta programme to the Galaxy S25, S25+, S25 Ultra, S25 FE, Z Fold7 and Z Flip7 in the UK. A wider stable rollout is expected afterwards, but Samsung hasn’t given UK owners an exact schedule yet.

What about the Galaxy S24 and S23?

Samsung’s current One UI 9 material references support across devices including the Galaxy S24 and S24 FE, Galaxy S23 and S23 FE, Fold6, Flip6, Fold5, Flip5 and several Galaxy Tab S9, S10 and S11 models. However, Samsung hasn’t published one neat UK rollout calendar covering all of them yet.

The Galaxy S23 series should receive Android 17 as its final major Android upgrade. Samsung promised the S23 four generations of Android OS updates, and it originally launched on Android 13.

So, what’s new in One UI 9?

Quite a bit.

Now Nudge looks at what’s happening on your screen and suggests the next useful action. If you’re arranging dinner through messages, for example, it may offer to save the restaurant to Maps or add the plan to your calendar without making you hop between several apps.

Now Brief gets much more personal. It’s already pulled together things such as your schedule, weather and other useful information. One UI 9 makes those briefings more customisable.

You can choose the types of information you’re interested in and create cards covering things such as health, weather and video. There are also action buttons that can take you directly to whatever needs doing next.

My FanCam can take a recorded video, track a person you’ve selected and automatically reframe the footage around them. You can then create a more tightly framed clip without manually following them through the entire video in an editor.

Photo Assist has also been upgraded. Instead of carefully digging through editing controls, you can describe the change you want using natural language, including by voice. One UI 9 can then use Galaxy AI to make the edit and lets you compare the result against the original.

A surprisingly sensible addition is Warranty and Care inside Settings. It can show warranty information for connected Samsung devices, run diagnostics, provide repair information and give access to Samsung Care+ and official support options where available.

One UI 9 also introduces a Security Brief within Now Brief, which can flag things such as malware warnings, apps installed from unknown sources and permissions that may need attention.

Samsung has added AI-powered Privacy Alerts, too. They’re designed to identify suspicious background permission requests, including apps repeatedly attempting to access precise location data.

There are smaller changes as well. Samsung has made the Quick Panel more customisable, added new tools to Samsung Notes and introduced accessibility improvements including Text Spotlight and updated TalkBack support.

How to check for One UI 9?

If One UI 9 is available for your Galaxy, you should eventually receive an update notification.

Impatient? Understandable. Go to Settings, then Software update and Download and install. Your phone will check Samsung's servers and show the update if it has reached your model and region.

If nothing appears, it doesn’t necessarily mean your phone isn’t eligible. Samsung rolls major updates out gradually, so two people with the same Galaxy model may not receive them on exactly the same day.

One small catch

Quite a few of One UI 9’s headline features require a Samsung Account, and availability can vary between devices, languages and countries. My FanCam, Now Brief, Now Nudge and several Galaxy AI features all come with their own compatibility requirements. So no, updating your four-year-old Galaxy won’t necessarily turn it into an S26 Ultra wearing a fake moustache.

Still, One UI 9 looks like a fairly substantial upgrade. Android 17 is underneath it, but Samsung has added enough of its own features that Galaxy owners should notice more than a new version number somewhere in Settings.
