Samsung's One UI 9 is bringing a major software upgrade to Galaxy devices, with a stronger focus on artificial intelligence, personalization, privacy and everyday usability.
Based on Android 17, One UI 9 introduces smarter Galaxy AI experiences such as Now Nudge, an improved Now Brief, Photo Assist and My FanCam. Samsung has also redesigned parts of the user experience and added new privacy and security controls.
The update is rolling out gradually across compatible Galaxy devices, so not every phone will receive every feature.
Here are 15 One UI 9 features worth knowing before you update your Samsung Galaxy phone.
1. Now Nudge Can Suggest Your Next Action
One of the biggest Galaxy AI improvements in One UI 9 is Now Nudge.
Instead of simply responding when you ask for help, Now Nudge can look at what you are doing on the screen and suggest useful next actions.
For example, it can help you move from a conversation to another task, such as checking your calendar, saving a location or completing another related action.
Samsung says Now Nudge has also been expanded to selected third-party apps and notifications, making the feature more useful throughout the day.
The goal is to reduce the number of manual steps needed to complete everyday tasks.
2. Now Brief Becomes More Personal
Samsung introduced Now Brief with earlier Galaxy devices, but One UI 9 makes it more customizable.
Users can create personalized briefing cards based on the information they want to see.
For example, users can receive selected information about weather, wellness and other daily activities.
Samsung also provides action buttons that can take users directly to tasks, such as opening a music application or getting directions to an event.
This makes Now Brief more useful as a daily information dashboard rather than simply another notification screen.
3. Photo Assist Gets Voice-Based Editing
Photo Assist is another major Galaxy AI feature in One UI 9.
Instead of manually adjusting multiple editing controls, users can describe the change they want in natural language.
Samsung says users can also use their voice to describe an edit.
For example, you could ask the tool to modify an image or make a particular visual change, and the AI will attempt to generate the result.
One UI 9 also allows users to compare the original and edited images side by side.
4. My FanCam Automatically Reframes Videos
If you record a group event, you don't always know who you will want to focus on later.
That's where My FanCam comes in.
The feature allows users to select a person after recording a video. Galaxy AI can then reframe the footage around that person and create a subject-focused clip.
This can be useful for:
- Family events
- Birthday parties
- Sports
- Concerts
- School functions
- Travel videos
- Social-media content
Instead of manually cropping the entire video, My FanCam can handle much of the work automatically.
5. Circle to Search Can Identify Multiple Items
One UI 9 also improves Circle to Search with Google.
Users can search for multiple objects, products or other items within an image rather than being limited to identifying a single item at a time.
This can be particularly useful when shopping or looking at an image containing several products.
For example, if a photograph contains multiple gadgets, you can use Circle to Search to investigate more than one item.
6. A More Flexible Quick Panel
Samsung has made the Quick Panel more customizable in One UI 9.
Brightness, sound and media controls can be adjusted more independently, while users get additional options for changing the size and arrangement of controls.
This means frequently used settings can be organized in a way that better matches individual preferences.
For people who regularly change brightness, volume or media controls, this is one of the practical improvements they may notice immediately.
7. Improved Multitasking With Multi Window
Samsung continues to improve multitasking in One UI 9.
Supported Galaxy devices can use two-way and three-way split-screen layouts, allowing multiple applications to remain visible at the same time.
This can be particularly useful on larger Galaxy phones, tablets and foldable devices.
For example, you can keep a browser open beside a messaging application or use multiple applications while working on a document.
8. Better FlexWindow Experience on Galaxy Flip Phones
Galaxy Z Flip users also get One UI 9 improvements designed specifically for the FlexWindow.
Users can access apps, notifications and Quick Panel controls from the cover display.
Widgets can also be moved, added or removed directly from the cover screen.
This means users can perform more tasks without opening the phone.
Feature availability naturally depends on the specific Galaxy foldable model.
9. Better Wallpaper Positioning
One UI 9 also improves wallpaper customization.
When setting up a supported lock screen, the system can automatically position the wallpaper so important parts of the image don't interfere with the clock and other interface elements.
Samsung says the system can also naturally extend parts of an image when adjusting the wallpaper position.
It is a small change, but it can make custom wallpapers look cleaner.
10. AI Assistant Activity Shows What AI Has Done
As Galaxy AI becomes more capable, transparency becomes increasingly important.
One UI 9 introduces AI Assistant Activity, which provides users with a view of actions performed by eligible AI assistants.
Users can see which applications were accessed, what actions were performed and when those actions happened.
This gives users more visibility into what their AI tools are doing on their behalf.
11. AI Privacy Alerts
Samsung is also introducing AI Privacy Alerts.
The feature is designed to identify applications that may be making excessive use of sensitive information, such as precise location or background permissions.
When potential risks are detected, the system can warn users and suggest reducing the amount of sensitive information an application can access.
This is becoming increasingly important as smartphones rely more heavily on AI and personalized services.
12. Protection Against Malicious Websites
Samsung is strengthening web protection in One UI 9.
When using Samsung Internet, a machine-learning-based system can warn users if they are about to access a potentially malicious website.
This can provide an additional layer of protection against dangerous links and websites.
It is particularly useful because malicious links can appear in messages, emails, social-media posts and other online content.
13. Stronger On-Device Privacy for Galaxy AI
Samsung's Personal Data Engine, together with technologies such as KEEP and Knox Vault, is designed to protect sensitive information used by Galaxy AI.
Samsung says users can also control where certain AI processing takes place, including on-device or in the cloud when supported.
This gives Galaxy users more control over how their personal information is handled.
However, the exact privacy controls and AI processing options can vary by device and feature.
14. Warranty and Care Hub
One UI 9 also adds a Warranty and Care area that brings several support functions together.
Users can check warranty information, get support, access diagnostics, arrange repairs and manage Samsung Care+ where available.
This is a practical addition because users no longer need to search through several different support options for basic device assistance.
Availability of individual services can vary by country and device.
15. Better Usability and Interface Improvements
Beyond the headline AI features, Samsung has also made broader usability improvements.
One UI 9 aims to make buttons, menus and navigation elements easier to use while keeping the interface consistent when switching between applications.
Samsung has also optimized the software for different form factors, particularly foldable devices.
The result is intended to be a smoother experience when moving between screens, applications and multitasking modes.
One UI 9: What's the Biggest Change?
The biggest change isn't simply a redesigned interface.
Samsung is increasingly turning Galaxy AI into an everyday assistant.
Features such as Now Nudge can suggest actions based on what is happening on the screen. Now Brief can provide personalized information, while Photo Assist and My FanCam can handle parts of photo and video editing.
At the same time, Samsung is adding more visibility and controls around privacy and AI activity.
Which Galaxy Phones Will Get One UI 9?
Samsung is rolling One UI 9 out gradually.
The official One UI 9 experience was first introduced on Samsung's latest Galaxy foldable devices, while the update is expanding to additional compatible Galaxy devices.
Samsung says availability can vary according to the device model, country, region, carrier and language.
The easiest way to check your individual device is through the Samsung Members app or by going to:
Settings → Software update → Download and install
If an update is available for your device, Samsung will show the available software version there.
Are All One UI 9 Features Available on Every Galaxy Phone?
No.
This is important before updating.
Some One UI 9 features require specific hardware or Galaxy AI capabilities. Other functions may be limited according to the device model, region or language.
For example, advanced camera features such as My FanCam naturally depend on the device's camera and processing capabilities.
Samsung also notes that some Galaxy AI features require a Samsung Account and may require an internet connection.

Before installing the update, make sure your phone has enough storage space and battery charge, and back up important data as a precaution.
