Quick Answer

Samsung’s One UI 9 rollout began on September 16, 2026, with the Galaxy S26 series and is expanding to more Galaxy devices in stages.

 It debuted with the new Galaxy Z Fold8 Ultra, Galaxy Z Fold8 and Galaxy Z Flip8 before Samsung began expanding the update to the Galaxy S26, S26+ and S26 Ultra on September 16, 2026.

The update is based on Android 17 and expands Galaxy AI, contextual assistance and security-related features.  New features include My FanCam, customizable Now Brief cards, Now Nudge, Privacy Alerts, Security Brief and improved document scanning.

Samsung has confirmed that One UI 9 will gradually expand to more Galaxy devices. However, the company has not published one single master list covering every supported phone and the exact rollout date for each model. Samsung recommends checking the Samsung Members app for device-specific compatibility.

One UI 9 Rollout Timeline

Samsung is releasing One UI 9 in phases instead of sending it to every Galaxy device simultaneously.

July 2026: One UI 9 debuts on new foldables

One UI 9 debuted on the Galaxy Z Fold8 Ultra, Galaxy Z Fold8 and Galaxy Z Flip8 before the wider rollout began.

These devices introduced the new One UI 9 experience alongside Samsung’s latest foldable hardware.

September 16, 2026: Galaxy S26 rollout begins

Samsung started the official expansion of One UI 9 on September 16, beginning with the Galaxy S26, Galaxy S26+ and Galaxy S26 Ultra. Samsung says the rollout will expand to additional markets and devices in stages.

September 2026 onward: More Galaxy devices

Samsung says One UI 9 will gradually reach additional Galaxy devices.Samsung’s beta programme included selected Galaxy Z Fold7, Galaxy Z Flip7, Galaxy S25-series and Galaxy S25 FE devices in selected markets. Beta availability should not be treated as confirmation of the final stable rollout schedule. 

Samsung has not provided a universal date for every eligible Galaxy model. Rollout timing can vary by device, country and carrier.

So, if your phone has not received the One UI 9 update yet, that does not automatically mean it is unsupported.

What Is New in One UI 9?

One UI 9 is not just a visual update. Samsung is using the release to expand Galaxy AI, make contextual suggestions more useful and add new security and device-care tools.

Here are the main One UI 9 new features.

Galaxy AI Gets More Context-Aware

Several of the biggest changes are designed around Galaxy AI.

Instead of requiring users to open a dedicated AI tool, One UI 9 can surface suggestions based on what they are doing.

My FanCam

My FanCam can automatically track a person selected from a recorded video and keep them centered as the scene changes.

For example, you could record a group performance and later select one person. My FanCam can reframe the footage around that person, reducing the need for manual video editing.

Samsung says My FanCam requires a Samsung Account, and availability can vary depending on the video and device. The feature also cannot work when there is no suitable subject to track.

Now Brief Gets Custom Cards

One UI 9 makes Now Brief more customizable through new Generative and Editable Cards.

Users can create or customise cards around information such as: 

• Weather
• Health
• Video

This lets users decide more directly what information appears in their daily brief instead of relying only on a fixed set of content.

Samsung notes that Now Brief features can vary by country, region, language, device model and app.

Now Nudge

Now Nudge provides context-aware suggestions based on what you are doing.

For example, while making plans in a supported messaging app, it can surface relevant suggestions or help users take the next step without leaving the conversation 

Samsung says Now Nudge works with certain messaging apps and that supported functions vary by region, language and device.

Call Brief

Call Brief is available on selected compatible Galaxy devices, but it should not be presented as a feature available on every One UI 9 phone.

It can display relevant information on the call screen, such as a related calendar event or the local time of the person you are calling.

Samsung has not highlighted Call Brief in its main September rollout announcement, so it is better to treat device-level availability separately from the core One UI 9 feature list. Current testing and compatibility reports show the feature on selected recent Galaxy flagships and foldables.

Privacy and Security Get More Attention

Samsung is also using One UI 9 to make security information easier to notice.

Privacy Alerts

Privacy Alerts use on-device AI to identify potential privacy risks.

Samsung says the feature can provide users with greater visibility into potential privacy risks and how apps access information. 

Samsung says feature availability can vary by device, country, region, language and software version. Do not treat Privacy Alerts availability as confirmation that every listed device has received the complete One UI 9 update 

Importantly, this is feature availability, not a blanket confirmation that every listed device has received the complete One UI 9 stable update.

Security Brief

Security Brief brings important security and privacy information into Now Brief.

It can surface alerts related to:

• Malware
• Apps from unknown sources
• Unnecessary permissions

The idea is to make potential security issues easier to spot without requiring users to dig through multiple settings menus.

Scam Detection

Samsung is also expanding Scam Detection to additional markets and languages.

Samsung says Scam Detection is expanding to additional markets and languages, but availability can vary by country, language, device and software version. 

More Useful Everyday Tools

The One UI 9 update also adds improvements beyond Galaxy AI.

Warranty and Care

Samsung is bringing more device-support functions directly into Settings through Warranty and Care.

Users can access options such as:

• Warranty information
• Device self-diagnostics
• Repair estimates
• Samsung Care+
• Service appointment booking

The available options can differ depending on the country and device.

Creative Studio

Creative Studio can now suggest image-generation ideas based on upcoming events.

For example, Samsung says it can suggest an image or greeting concept when a friend’s birthday is approaching.

Interpreter

The Interpreter app gets a new Thread View.

This helps users follow translated conversations by making earlier exchanges easier to reference. Samsung also says Conversation Mode translation and playback with compatible Galaxy Buds have been improved.

Document Scan

One UI 9 improves Document Scan for difficult-to-scan materials.

It can handle documents such as curved book pages and corner-folded papers with less manual adjustment.

Compatible large-screen Galaxy devices also get optimized views, while Finger Eraser has been improved for cleaner scans.

Voice Recorder

Voice Recorder can now present generated summaries in a more structured format.

Instead of a long block of text, summaries can use elements such as:

• Headings

• Tables

• Structured sections

This can make long recordings easier to review.

Which Samsung Phones Get One UI 9?

This is where it is important to separate confirmed rollout information from expected eligibility.

Samsung’s rollout announcement says One UI 9 will expand to more Galaxy devices, but it does not provide one permanent master list covering every model and rollout date. It does not provide one permanent master list covering every Galaxy model.

Devices with One UI 9 already available or introduced

Samsung’s September announcement confirms the S26 series as the starting point for the wider rollout.

Devices reported or listed in Samsung’s One UI 9 beta expansion 

Samsung’s September 1 beta announcement included:

• Galaxy Z Fold7

• Galaxy Z Flip7

• Galaxy S25

• Galaxy S25+

• Galaxy S25 Ultra

• Galaxy S25 FE

The beta was available in selected markets, including India, Korea, the UK and the US.

However, beta availability should not be treated as the same thing as the final stable rollout date.

What about Galaxy S24 and S23?

Samsung has not published a single official One UI 9 master list confirming the stable rollout schedule for every older Galaxy model.

Reports and testing references indicate possible One UI 9 compatibility for the Galaxy S24 and S23 series, but Samsung has not published a complete stable rollout list for these models.  However, the availability of individual Galaxy AI features differs considerably between generations.

This distinction matters because a phone can receive One UI 9 without receiving every new Galaxy AI feature.

What about Galaxy A phones?

One UI 9 testing has reportedly appeared on several newer Galaxy A-series models, but testing references should not be treated as Samsung’s final stable rollout list. 

These testing references should not be presented as Samsung’s final stable rollout list unless Samsung officially confirms the model.

For the most accurate answer for your phone, Samsung recommends checking the Samsung Members app and the Software Update section on the device itself.

One UI 9 Eligibility vs Galaxy AI Eligibility

Getting the Samsung One UI 9 update does not automatically mean your phone gets every new Galaxy AI feature.

This is one of the most important points to understand about the update.

For example, current compatibility testing reported by SamMobile shows that the newer S24, S25 and S26 series support more of the headline One UI 9 AI features, while some older models receive the operating-system update without those specific AI additions.

The same applies to FE models and older foldables.

Samsung also states that feature availability can vary by:

• Device model
• Country
• Region
• Language
• Carrier
• Supported apps

So the One UI 9 supported devices list and the One UI 9 Galaxy AI supported devices list should not be treated as identical.
