Stable update availability may vary depending on the country, carrier, and device. A phone being listed in the beta program does not necessarily mean that its stable update has already been released.

What’s New in S26 Ultra One UI 9?

One UI 9 focuses on making Galaxy smartphones more personalized, convenient, and secure. Samsung has introduced new Galaxy AI experiences alongside changes to the interface and everyday smartphone features.

1. Galaxy AI and Smarter Assistance

Galaxy AI continues to evolve in One UI 9, with a greater emphasis on context-aware experiences. The goal is to provide useful suggestions based on what users are doing and the information available on their devices.

The actual suggestions and availability may depend on the device and software support.

4. My FanCam: A New Tool for Video Creators

My FanCam is one of the new AI-powered camera features associated with One UI 9.

It helps keep a selected person in focus in a video and can reframe footage into different aspect ratios. This may make it easier to prepare videos for social media platforms.

The feature could be particularly useful for people who create videos for Instagram Reels, YouTube Shorts, and other social platforms.

These changes are intended to make frequently used controls easier to access.

7. Improvements to Security and Privacy

One UI 9 includes additional security measures related to suspicious apps and potential threats.

According to the reported feature details, the system may warn users about certain high-risk apps, restrict their installation or execution in specific circumstances, and suggest removing them.

The update also focuses on making device security and privacy information easier to understand.

8. Accessibility Improvements

S26 Ultra One UI 9 includes additional accessibility options designed to make Galaxy phones easier to use.

Potential Benefits for Everyday Use

These are software features. They do not automatically change the phone’s processor, camera hardware, or battery capacity.

Samsung One UI 9 Update: Which Phones Are Getting It?

It is important to understand the difference between phones participating in beta testing and those that have received the stable update. Samsung’s stable rollout reportedly began with the Galaxy S26 series. Meanwhile, the company expanded its One UI 9 beta program in September to include the Galaxy S25 series, Galaxy Z Fold 7, and Galaxy Z Flip 7.

1. Galaxy S Series: Phones Included in Beta Testing

The following Galaxy S-series phones have been reported as participants in the public beta program. This does not mean that every model has already received the stable update.

The Galaxy S23 series has reportedly received a second beta build in some markets. The Galaxy S24 FE has also reportedly progressed to Beta 2.

2. Galaxy Z Series: Foldable Phones in the Beta List

Samsung’s foldable smartphones are also part of the One UI 9 testing program.

The inclusion of the Galaxy Z Fold 6 and Z Flip 6 is notable because Samsung has extended testing beyond its newest foldable generation.

3. Galaxy A Series: Budget and Mid-Range Phones in the Beta List

Several Galaxy A-series devices have also reportedly joined the public beta program.

The Galaxy A15 5G reportedly received its first public One UI 9 beta in India on September 22, 2026.

The update package is reported to be around 2.76GB and includes the September 2026 security patch.

4. What About the Galaxy A07 and Galaxy M34?

The Galaxy A07 and Galaxy M34 have also reportedly appeared in Samsung’s internal One UI 9 development process.

However, the available information does not confirm public beta enrollment for either device.

The Galaxy A16 5G has also been mentioned as a possible future beta participant, but it should not be included in the confirmed public beta list without an official enrollment announcement.

S26 Ultra One UI 9 Stable Update: Which Phones Have Received It?

The stable rollout is more limited than the beta testing list.

According to the reported information available for September 2026, the stable rollout began with the Galaxy S26 series in South Korea.

The stable update began rolling out in South Korea on September 16. Reports also indicate that the Galaxy S26 series started receiving the update through T-Mobile in the United States on September 23.

Important: Galaxy S26 Ultra users in India should check their phone’s software update settings to confirm availability. Being part of the beta program does not mean that the stable update has already been released.

How to Check for the S26 Ultra One UI 9 Update in India and the USA

Update availability in India and the United States can vary depending on the phone model, region, and carrier.

Samsung has reportedly included India and the US among the selected markets for its beta program.

How to Check for the Stable Update

1. Open Settings on your Samsung Galaxy phone.

2. Go to Software update.

3. Tap Download and install.

4. Your phone will check for available updates.

5. If One UI 9 is available, follow the on-screen instructions.

If the update does not appear, it may not have been released for your model or region yet.

How to Join the Samsung S26 Ultra One UI 9 Program

If the beta program is available for your phone and region, you may be able to enroll through the Samsung Members app.

A Samsung Account is required to enroll in the beta program. Backing up your data before installation is also recommended.

Things to Know Before Installing the Beta

• Beta software may contain bugs or app compatibility issues.

• Battery consumption and performance may change.

• Back up your data before installing the update.

• Avoid manually installing firmware intended for another region.

• Returning from beta software to a stable version may require a data reset.

It is worth understanding these risks before installing beta software on your primary phone.

Will Every Galaxy Phone Get the Same S26 Ultra One UI 9 Features?

No. Even when multiple phones run the same One UI version, not every feature is necessarily available on every device.

Some features depend on hardware capabilities, Galaxy AI support, region, language, and app version. Therefore, it would be incorrect to assume that the Galaxy A15 5G will offer the same complete experience as the Galaxy S26 Ultra.

After installing the update, check the feature list and settings available on your specific phone.
