One UI 9 (Android 17): The Best New Features and How to Use Them

Tested on:. Everything below about availability, release dates and requirements comes from Samsung’s own newsroom, support pages and changelog. Where we describe how a feature behaves day to day, that comes from our own Galaxy, and we’ve marked the spots the owner still needs to confirm.

This is our main guide to Samsung’s 2026 software update. If you just want to install it, jump to how to get the One UI 9 update. For everything else Android, our Android hub collects the related guides.

What is One UI 9?

One UI is the software layer Samsung puts on top of Android on its Galaxy phones, tablets and watches. One UI 9 is the version built on Android 17, the Android release Google shipped to Pixel phones in June 2026. You get Google’s Android 17 changes underneath, plus Samsung’s own design, apps and Galaxy AI tools on top.

That’s why One UI version numbers don’t match Android’s. The update before this one was One UI 8.5, which Samsung started rolling out in May 2026. One UI 9 is a bigger step: Samsung describes it as an easier, more seamless experience across phones and foldables, with Galaxy AI that is “richer, more personal, and more helpful.”

In practice it is an evolution rather than a redesign. The look introduced in One UI 7 stays. What changes is mostly what happens around your apps: smarter suggestions, more control over the Quick Panel, and more warnings when an app does something it shouldn’t.

One UI 9 release status (October 2026)

Samsung rolls One UI updates out in waves: newest flagships first, then last year’s models, then older and mid-range phones. Carrier-locked phones in the US often get the update days or weeks after unlocked models in other countries. Here is where things stood at the time of writing (early October 2026).

Which phones get One UI 9?

Samsung hasn’t published a single dated schedule. Its official answer is to check the Samsung Members app, which shows eligibility and expected dates for your exact model. The best official clue is a footnote in Samsung’s rollout announcement listing the devices that support One UI 9’s AI Privacy Alerts:

Galaxy A, M and F mid-range phones usually follow later, and not every model gets every feature.

The best One UI 9 features, one by one

Samsung’s changelog is long, so we’ve grouped the changes by what you’ll notice first. For each one we say what it does, where to find it, and what it needs. Some features are foldable-only or depend on your country, language or carrier, so a few items below may not appear on your phone.

1. Now Nudge shows up in more places

Now Nudge is Samsung’s suggestion engine. It reads what’s on screen and offers a next step, such as adding a dinner plan to your calendar or saving an address someone texted you to Google Maps, without switching apps. In One UI 8.5 it lived mostly in the Samsung Keyboard. In One UI 9 suggestions also appear in conversation notifications and as a floating button in the bottom-right corner of the screen.

Where: Samsung says you enable it in Settings first, then it appears on its own when it’s relevant. Look under Settings → Galaxy AI → Now Nudge. Needs: a Samsung account. Text prompts work in Samsung Messages, Google Messages and Google Chat, and Samsung lists 16 supported languages, including English and Spanish.

2. My FanCam keeps one person in frame

Record a wide video of a school play, a dance floor or a match, then pick one person and My FanCam reframes the clip so they stay centered. You can choose the aspect ratio, which makes it handy for vertical social clips. It works on videos you’ve already recorded, so you don’t need to plan anything while filming.

1. Open Gallery and play the video you want to edit.
2. Tap the Galaxy AI icon (the four-point star).
3. When the people Samsung can track are highlighted, tap the person you want to follow.
4. Choose an aspect ratio, preview the result and save it as a new clip.

Needs: a Samsung account. Samsung notes that results vary by video and that it can’t do anything if there’s no clear subject to track.

3. A Quick Panel you can actually rearrange

The Quick Panel (the toggles you get when you swipe down from the top-right corner) is more flexible. You can resize the brightness slider, the volume slider and the media player independently, and separate the sound mode button from the volume slider. If you’ve ever wished the media controls took up less room, this is the fix.

Where: swipe down from the top-right corner, tap the Edit (pencil) icon, then drag and resize the controls. No Galaxy AI or account needed.

4. Now Brief you can customize, plus a Security Brief

Now Brief is the daily summary card that shows your schedule, weather and suggestions. One UI 9 adds what Samsung calls Generative and Editable Cards: you choose what you want briefings about, across health, weather and video, and action buttons let you jump straight into a task. A new Security Brief also adds alerts about malware, apps from unknown sources and unnecessary permissions to Now Brief.

Where: the Now Brief widget on the Home screen or the Edge panel. Settings live under Settings → Galaxy AI → Now brief. Needs: a Samsung account, and some cards need a network connection.

5. Warranty and care, right in Settings

This one is easy to overlook and genuinely useful. A new Warranty and care menu in Settings shows warranty coverage for Galaxy devices linked to your Samsung account, runs self-diagnostics, gives repair cost estimates and lets you book a service appointment or manage Samsung Care+. If you’re chasing a battery or hardware problem after updating, this is now the first place to look.

Where: Settings → Warranty and care. Available options vary by country, and repair estimates aren’t offered for every model.

6. Lock down your phone in one move

If you’re worried someone might force you to unlock your phone with your face or fingerprint, you can now lock it down instantly. Press and hold Volume down and the Side button together, or tap the Power button in the Quick Panel. The next unlock then needs your PIN, pattern or password, not biometrics.

7. Privacy alerts that use on-device AI

One UI 9 adds three layers of warnings. A blue indicator now appears at the top of the screen whenever an app reads your location, and tapping it in the Quick Panel shows which app it was. AI Privacy Alerts watch how apps use permissions on the device and flag unnecessary background access. And apps Samsung identifies as malicious or vulnerable are blocked from opening until you decide whether to remove them.

Samsung’s US page also lists AI Assistant Activity, a log of the actions AI assistants have taken in your apps, and malicious-site warnings in Samsung Internet. If an alert makes you wonder whether something is already wrong, our guide on how to tell if your phone has been hacked walks through the checks calmly.

8. Interpreter, Document Scan and Voice Recorder upgrades

Three Galaxy AI tools get practical upgrades. Interpreter gains a Thread View, so you can scroll back through a translated conversation while you’re still talking, and translation in Conversation mode is faster. Document Scan handles curved book pages and folded corners with less manual cropping. Voice Recorder summaries now use headings and tables, which makes meeting notes easier to skim.

Needs: Interpreter needs a Samsung account, and some languages need a language pack download. During calls, the call screen can also show related events and information.

9. Photo Assist by voice and Creative Studio prompts

In the Gallery, Photo Assist now lets you describe an edit out loud instead of typing it, then compare the before and after side by side. Open a photo, tap the Galaxy AI icon and speak. Creative Studio also suggests image ideas based on upcoming events, such as a friend’s birthday, and the Contacts app links straight to it for making profile cards.

Samsung lists 41 languages for Photo Assist. Generated images come with Samsung’s usual caveat that accuracy isn’t guaranteed, and Creative Studio needs a network connection and a Samsung account.

10. Samsung Health redesign

Samsung Health gets a new look with resizable Home cards grouped by Activity, Sleep, Mindfulness and Nutrition. You can log mood and meals straight from the home screen, use the camera for faster input, and view trend charts by hour, day or week. New tools include a cardio load tracker, a Fitness Index score, a heart health score, and a Hearing tracker that uses Galaxy Watch and headphone levels.

11. Smaller changes worth knowing

• New Lock screen clock: the default clock is redesigned and adapts to your wallpaper.
• Bixby: raise the phone to your mouth and talk, no wake word needed. You can also search, rename and pin past Bixby chats, and add a Bixby widget to the Home screen.
• Samsung DeX: move app windows between desktops from the window menu, and switch desktops from previews at the top of the Recents screen.
• Samsung Notes: decorative tapes and more pen line styles.
• Scam Detection: Samsung’s call-scam warning expands to more countries and languages, including Japan, Canada and India.

12. Accessibility improvements

Accessibility gets some of the most thoughtful changes. Text Spotlight lets you tap any text to show it enlarged and highlighted in a floating window, with your own font size and colors. Select to speak reads out a selected item without turning on full TalkBack. TalkBack itself now updates through the Play Store, combining features Google and Samsung previously offered separately.

Keyboard users get adjustable Mouse keys speed and acceleration, number pad pointing, and physical keyboard shortcuts for Accessibility settings. A What’s new menu in Settings → Accessibility lists the changes so you can try them.

Foldable-only extras

Some of what Samsung advertises for One UI 9 is tied to the new foldables: two-way and three-way split view, a more capable FlexWindow cover screen on the Z Flip8, and wallpaper that positions itself around the cover screen clock. If you have a Galaxy S phone, don’t expect these.

Which One UI 9 features need Galaxy AI or a Samsung account?

Most of the AI features need you to be signed in to a Samsung account, and several need an internet connection. Here’s a summary based on Samsung’s own footnotes.

On cost: Samsung originally said core Galaxy AI features would be free until the end of 2025, and has since said core features will stay free, while leaving room for paid premium services in future. If you’d rather not use some of these tools at all, see how to turn off Galaxy AI features you don’t use. Samsung also lets you choose whether some AI processing happens on the device or in the cloud.

What moved or changed in One UI 9

Big updates move things around, and this is where readers usually get stuck. These are the changes Samsung itself calls out:

• Volume down + Side now locks the phone down instead of opening the power menu (see feature 6).
• Replace swipe with single tap moved from the Assistant menu to Dexterity and interaction in Accessibility settings.
• Sound mode can now be split from the volume slider in the Quick Panel, so it may not be where you expect.
• Warranty and diagnostics tools that used to sit in Samsung Members now also appear in Settings.

How to get One UI 9

When the update is available for your phone, you’ll usually get a notification. To check manually:

1. Open Settings.
2. Scroll to the bottom and tap Software update.
3. Tap Download and install (some carrier models say Check for updates).
4. If One UI 9 is offered, connect to Wi-Fi and a charger and follow the on-screen steps.

Make sure you have a few gigabytes free before you start, because the download and install need room. If your phone is tight on space, our guide to freeing up storage on a Samsung Galaxy covers the quickest wins. For carrier timing, the beta-to-stable path and what to do if the update isn’t showing, see how to get One UI 9.

Should you update to One UI 9 now?

For most people, yes. Major updates bundle security fixes, and the US Galaxy S26 build includes the September 2026 security patch. Install it when your phone offers it rather than waiting months.

Three sensible precautions: back up first (Samsung doesn’t offer an official way back to One UI 8.5), check reviews of any banking or work app you rely on, and expect battery life to dip for a couple of days while the phone settles. If that drain lasts longer, our One UI 9 battery drain checklist lists the settings to check first. Setting up a new Galaxy that ships with One UI 9? Start with how to set up a new Android phone.

Our take

On paper, One UI 9 is a steady, practical update rather than a dramatic one. The changes most people will feel are the Quick Panel, the Warranty and care menu and the new privacy alerts, while Now Nudge and My FanCam are the ones Samsung is betting on.
