Good news if you own a Galaxy S24, Galaxy Z Fold 6 or Galaxy Z Flip 6. Samsung has started rolling out the stable One UI 9 update to those five devices, bringing Android 17 to millions of phones that first launched back in 2024. The rollout began in Korea on 7 October 2026, and Samsung is expected to expand it to other markets, including the UK, very soon.
This is one of the biggest software releases of the year for Samsung owners. The One UI 9 update is built on Android 17 and follows the rollout to the Galaxy S25 and Galaxy S26 series, which started receiving the stable version recently, as well as the Galaxy Z Fold 7 and Z Flip 7. The newest Galaxy Z Fold 8, Z Fold 8 Ultra and Z Flip 8 shipped with One UI 9 out of the box, so this release is really about bringing Samsung’s older flagships up to speed with the rest of the range.
Which phones are getting the One UI 9 update
Samsung is pushing the stable One UI 9 update to five devices in this wave:
- Galaxy S24
- Galaxy S24 Plus
- Galaxy S24 Ultra
- Galaxy Z Fold 6
- Galaxy Z Flip 6
In Korea, the update is currently reaching Galaxy Z Fold 6 and Z Flip 6 owners who took part in the One UI 9 beta programme first, with the wider rollout expected to follow in stages. Beta testers are seeing a download of around 500MB on the S24 series and 408MB on the foldables, but anyone coming from the older stable software should expect a considerably larger file, roughly 3.8GB and 3.5GB respectively.
Samsung usually staggers major updates by region and by carrier, so some UK owners may see the notification days or even weeks before others. That staged approach is normal, and it lets Samsung catch any early problems before the update reaches every device.
What is new in One UI 9
One UI 9 is Samsung’s take on Android 17, and it brings a mix of new features and refinements across the system. Based on the version already live on newer Galaxy phones, owners can expect Now Nudge, a more customisable Quick Panel, an upgraded Samsung DeX desktop mode, improvements to Samsung Notes and a deeper integration with Google’s Gemini assistant.
Now Nudge is designed to surface timely, contextual reminders without you having to dig through apps, while the refreshed Quick Panel gives you more control over which toggles and sliders sit front and centre. Samsung DeX continues its evolution into a genuinely useful desktop replacement, and the tighter Gemini integration means AI assistance is woven more deeply into everyday tasks, from summarising notes to handling multi step requests.
As always, expect the usual round of performance optimisations, smoother animations and bug fixes under the surface. If you want a flavour of where Samsung is heading with its software, our earlier look at the Galaxy S25 One UI 9 beta and its new Galaxy AI features covers some of the headline additions in detail.
When will UK owners get the One UI 9 update
Samsung has not published a region by region timetable, but history suggests the UK is usually among the first wave of markets after Korea. The Galaxy S25 and S26 series started receiving stable One UI 9 recently, so the S24 generation following close behind fits Samsung’s usual pattern. Keep an eye out over the coming days and weeks.
Your phone will notify you automatically once the update is available, but you can also check manually. Open Settings, head to Software update and tap Download and install. Because the download is hefty, it is worth connecting to Wi-Fi and making sure you have plenty of battery, or keeping the phone plugged in, before you start the installation.
Should you install it straight away
For most people, yes. Major One UI updates bring the latest Android security patch, new features and a general polish that keeps an older flagship feeling fresh. The Galaxy S24 series and the 2024 foldables are all inside Samsung’s generous seven year update window, so this is exactly the kind of upgrade that extends the life of your phone and delays the need to buy a new one.
That said, if you rely on your phone for critical work, waiting a few days to confirm there are no widespread issues is never a bad idea. Early adopters in Korea will be the canaries here, and any serious problems tend to surface within the first 48 hours of a rollout. A quick search of owner forums before you tap install can save you a headache.
Either way, this is one of the most significant free upgrades Galaxy S24, Z Fold 6 and Z Flip 6 owners will receive this year. After months of beta testing, the stable One UI 9 update is finally on its way, and UK owners should not have long to wait.
