One UI 9 Beta Expands to 6 Samsung Galaxy Phones

September 2, 2026 admin

Samsung is expanding its One UI 9 beta program beyond the Galaxy S26 series, giving owners of several 2025 flagship Galaxy phones their first opportunity to test the company’s Android 17-based software. The expansion marks an important step toward a wider stable rollout of Samsung’s next major software update.

Samsung confirmed on September 1 that the beta program will expand to the Galaxy S25 family and Samsung’s latest foldable generation. The eligible devices include the Galaxy S25, Galaxy S25+, Galaxy S25 Ultra, Galaxy S25 FE, Galaxy Z Fold7 and Galaxy Z Flip7.

The beta will be available in selected markets, including India, South Korea, the United Kingdom and the United States. Users who want to participate can register through the Samsung Members application, although Samsung notes that availability and timing can vary by market.

One UI 9 Beta Reaches More Galaxy Devices

The One UI 9 beta originally launched for the Galaxy S26 series in May. That made Samsung’s newest flagship phones the primary testing platform for the Android 17-based interface.

The September expansion significantly broadens the testing pool.

Samsung has now confirmed six additional models:

Galaxy S25
Galaxy S25+
Galaxy S25 Ultra
Galaxy S25 FE
Galaxy Z Fold7
Galaxy Z Flip7

This is particularly significant for Galaxy S25 owners because it gives the 2025 flagship lineup access to Samsung’s next major Android platform update before the final public release.

The Galaxy S25 series was already expected to receive Android 17 as part of Samsung’s long-term software support strategy. However, entering the beta program allows users to test the software much earlier and gives Samsung an opportunity to identify bugs and performance issues before the stable rollout.

Samsung One UI 9 Beta Is Based on Android 17

At the heart of the update is Android 17.

Samsung announced the first One UI 9 beta for the Galaxy S26 series in May, describing it as software built on Android 17 with improvements to creativity, accessibility, customization and security.

One UI 9 represents Samsung’s next major software generation. It is designed to build on the company’s Galaxy experience while incorporating new capabilities introduced by Google’s latest Android platform.

For users, that means the update is more than a visual refresh.

Android platform changes can affect privacy controls, notifications, system behavior, application compatibility, performance and background activity. Samsung then layers its own One UI design and Galaxy-specific features on top.

That combination makes beta testing especially important.

A feature may work correctly on Google’s reference Android implementation but behave differently after Samsung’s interface and device-specific services are added.

Galaxy S25 Owners Finally Join the Testing

The biggest part of this One UI 9 beta expansion is arguably the Galaxy S25 family.

The Galaxy S25, S25+ and S25 Ultra were among Samsung’s most important flagship phones of 2025. Bringing them into the beta program means a large existing user base can now help test Android 17 before Samsung pushes the software to the broader Galaxy ecosystem.

The Galaxy S25 FE is also included.

That is notable because the FE model provides Samsung with another hardware configuration to test. While it remains part of the S25 generation, its hardware profile differs from the premium S25 Ultra.

Testing across multiple configurations can help Samsung identify device-specific problems before the stable release.

For owners, however, there is an important trade-off.

Beta software is not intended to provide the same level of stability as a finished release.

Users who depend on their phones for work, banking, travel or other critical tasks may want to wait for the stable version rather than installing an early test build.

Galaxy Z Fold7 and Z Flip7 Also Get the Beta

Samsung is also bringing One UI 9 beta to the Galaxy Z Fold7 and Galaxy Z Flip7.

Foldable phones create additional challenges for software developers because the interface needs to adapt to different screen sizes and configurations.

The Galaxy Z Fold7 can switch between a compact cover display and a much larger internal screen. The Z Flip7 has its own combination of cover-screen functionality and a traditional internal display.

Consequently, One UI needs to handle changes in layout, multitasking and application behavior across different form factors.

Adding these devices to the beta program gives Samsung an opportunity to test Android 17 and One UI 9 in more demanding scenarios.

It also means developers can gather feedback about how the new software behaves when users move between displays.

One UI 9 Beta Availability Depends on Region

Samsung has confirmed that the beta program will be available in India, Korea, the U.K. and the U.S.

However, users should not assume that every eligible phone in those countries will receive the beta at exactly the same time.

Samsung explicitly says availability and timing may vary by market.

The registration process is handled through the Samsung Members app. Eligible users can look for the One UI 9 beta program within the application and follow Samsung’s instructions to enroll.

The staged approach is normal for major software betas.

Samsung can monitor the rollout, evaluate feedback and adjust the release before expanding it further.

What Users Should Know Before Installing One UI 9 Beta

Although the arrival of Android 17 is exciting, beta software comes with risks.

Users may encounter bugs, crashes, battery problems, application compatibility issues or unexpected behavior.

Some third-party applications may also need updates before working correctly with the new operating system.

That does not mean the beta is necessarily unstable. Rather, its purpose is to expose problems that Samsung can fix before the final version reaches millions of users.

Anyone considering enrollment should therefore back up important information first.

It is also wise to make sure the phone has enough free storage and battery capacity before beginning the installation.

The first beta builds can be particularly large because they introduce the underlying Android platform update as well as Samsung’s software changes.

One UI 9 Beta Builds on Samsung’s Earlier Testing

Samsung has already spent several months testing One UI 9 with the Galaxy S26 series.

The company began the Galaxy S26 beta program in May, meaning the newer flagship family has served as an early testing platform before Samsung expanded the program to older devices.

That approach makes sense from a software development perspective.

Samsung can first test the new operating system on its newest hardware before expanding it to additional processors, cameras, displays and device configurations.

The September expansion suggests that the software has progressed far enough for Samsung to involve a much wider range of Galaxy hardware.

It does not guarantee an immediate stable release for every model, but it is a positive sign that development is moving forward.

Why the One UI 9 Beta Expansion Matters

The One UI 9 beta expansion is important for more than just Galaxy S25 owners.

It shows Samsung moving into a broader phase of Android 17 development.

Instead of limiting testing to its newest flagship family, the company is now gathering feedback from owners of conventional flagship phones, FE devices and foldables.

That gives Samsung a much larger testing environment.

Different users also interact with their phones in different ways. Some rely heavily on cameras and social media, while others use multitasking, gaming, productivity applications or foldable-specific features.

A broader beta community can therefore reveal problems that may not appear during internal testing.

It can also help Samsung understand which new features users actually find useful.

Android 17 Could Bring a Major Galaxy Software Refresh

One UI 9 is expected to combine Android 17’s platform improvements with Samsung’s own interface and Galaxy ecosystem features.

Samsung previously highlighted improvements related to creativity, customization, accessibility and security when announcing the beta.

Those areas are becoming increasingly important as smartphone software becomes more dependent on artificial intelligence and personalized experiences.

Samsung has also been using One UI as a way to distinguish Galaxy devices from other Android phones.

The company controls both the hardware and much of the software experience, allowing it to integrate features across smartphones, tablets, wearables and other Galaxy products.

One UI 9 will continue that strategy.

Samsung’s Stable One UI 9 Release Is Getting Closer

The expansion of the One UI 9 beta does not provide a specific stable-release date.

Samsung has only said that the program will expand to the additional devices starting in September.

Still, expanding a major beta program is an important milestone.

The more devices Samsung adds to testing, the more data it can collect before finalizing the software.

Galaxy S26 owners have already been testing One UI 9 for months. Now the Galaxy S25 and Z Fold7 and Z Flip7 families are joining the process.

That creates a much broader testing environment at a time when Samsung is preparing Android 17 for a larger portion of its ecosystem.

What Galaxy Owners Should Do Now

Owners of eligible devices who want to participate should check the Samsung Members app.

The eligible models are the Galaxy S25, S25+, S25 Ultra, S25 FE, Z Fold7 and Z Flip7, with availability depending on market.

If the beta program appears, users can follow Samsung’s enrollment instructions.

Those who do not see the program should not assume that their device is unsupported. Samsung says availability and timing can vary by country, meaning the rollout may take time to reach individual markets.

For users who prioritize reliability, waiting for the stable release remains the safer choice.

For enthusiasts and developers, however, the beta provides an opportunity to experience Android 17 and One UI 9 before most Galaxy owners.

A Major Step Toward Samsung’s Android 17 Rollout

Samsung’s decision to expand the One UI 9 beta to six additional Galaxy devices marks one of the biggest stages yet in its Android 17 rollout.

The Galaxy S25 family, including the S25 FE, is now moving into the testing process alongside Samsung’s latest foldables.

The expansion also confirms Samsung’s commitment to testing One UI 9 across a wider selection of hardware before the software reaches the broader Galaxy ecosystem.

For Galaxy owners, the message is clear: Android 17 is moving closer.

The final One UI 9 release may still require additional testing and refinement, but Samsung is no longer keeping its next-generation software confined to its newest phones.

With more Galaxy users now able to participate, Samsung has a larger opportunity to identify bugs, refine features and improve compatibility before the stable update arrives.

For anyone with an eligible Galaxy device, September could therefore be the beginning of a much closer look at Samsung’s Android 17 future.
