Samsung is expanding its One UI 9 beta program faster than many expected. After initially opening the beta for the Galaxy S25 series and confirming that its 2025 foldables would be next, Samsung has now turned its attention to the Galaxy S24 family. Owners of the Galaxy S24, Galaxy S24 Plus, and Galaxy S24 Ultra are now able to experience Android 17 through the first One UI 9 beta, which has started rolling out in several key markets.

Where is the One UI 9 beta available?

The rollout was first spotted in the United States, where Galaxy S24 users reported access through the Samsung Members app. According to tipster Tarun Vats on X, the US build carries the version number S92xU1UEU6ZZHL. The beta then expanded to India and South Korea, with builds identified as S92xBXXU6ZZHL for India and S92xNKSUHZZHL for Korea. This means the beta is now confirmed for all three Galaxy S24 variants in at least these three regions.

Interestingly, the US appeared to receive the beta before Samsung's home market of South Korea, which is somewhat unusual for Samsung’s rollout pattern. However, the regional launches happened within a short window, suggesting that this was a staggered release rather than an intentional shift in priority.

What does the update include?

The first One UI 9 beta is a significant download, weighing in at roughly 3.6GB. It upgrades the device to Android 17 and includes the August 5, 2026 security patch. Beyond the foundational OS update, Samsung has packed the beta with new features and improvements aimed at personalization, productivity, and security.

While a detailed changelog has not been fully disclosed, early reports and Samsung's own preview materials suggest that One UI 9 introduces a refined visual language, enhanced lock screen customization, improved notification management, and deeper integration with Android 17's underlying privacy and security enhancements. Users can also expect smoother animations and better battery optimization, as Samsung continues to refine its software layer for both performance and polish.

How to join the One UI 9 beta

Galaxy S24 owners in supported markets can join the program through the Samsung Members app. Once enrolled, the beta update should appear under Settings > Software update > Download and install. As is typical with beta software, Samsung recommends backing up important data before installing the update. Users should also be aware that some apps may not work properly until they are updated to support Android 17.

Beta participation is not for everyone. There may be bugs, compatibility issues, and unexpected behavior. However, for those who want a first look at future Galaxy features and are willing to provide feedback, enrolling in the beta is a straightforward process.

Galaxy S24 series: a quick recap

The Galaxy S24 series launched in early 2024, comprising the standard Galaxy S24, the Galaxy S24 Plus, and the Galaxy S24 Ultra. These devices were Samsung's first to feature a dedicated AI-powered experience, branded as Galaxy AI. They came with the Exynos 2400 processor in most global markets, while the US and China received the Qualcomm Snapdragon 8 Gen 3 for Galaxy chipset. The series was praised for its bright LTPO displays, capable camera systems, and Samsung’s promise of seven major Android OS updates and seven years of security patches.

This long-term software support commitment is now paying off for Galaxy S24 users. Receiving the Android 17 beta in September 2026 puts the S24 series on track to receive at least seven major updates, meaning the phones will be supported through Android 21. The beta also demonstrates Samsung’s ability to roll out updates efficiently to past-generation flagships, not just its newest hardware.

Comparison with previous Samsung beta programs

Samsung has a well-established beta program that typically begins with the latest flagship devices. For example, the Galaxy S25 series received its One UI 9 beta a few weeks earlier. The Galaxy Z Fold 7 and Galaxy Z Flip 7 are expected to be next in line. After that, Samsung often rolls the beta out to older flagships such as the Galaxy S24 series.

The beta program for Android 16 (One UI 8) followed a similar trajectory, but the timing for Android 17 seems to be slightly accelerated. This could be due to improved internal testing processes, more streamlined hardware platforms, or a strategic push to get more devices involved early in the cycle. By expanding the beta to the Galaxy S24 series in early September 2026, Samsung is giving its users plenty of time to test the software before the stable release is expected later this fall.

What is new in Android 17?

Android 17, Google's next major mobile OS release, builds on the privacy and customization themes introduced in previous versions. While Google has been tight-lipped about the full list of features, developer previews and leaks suggest several key improvements:

• Enhanced multitasking: Improved split-screen and picture-in-picture modes, with more flexible window resizing.
• Battery and thermal management: New adaptive battery features that learn user patterns more deeply, and better thermal throttling to keep devices cool during intense tasks.
• Privacy dashboard enhancements: More granular controls over camera and microphone access, and newer tools for detecting background activity.
• Animation and haptic improvements: Smoother system animations and better support for high-fidelity haptic feedback.
• Accessibility upgrades: Enhanced TalkBack, new magnification options, and improved support for hearing aids.

One UI 9 layers Samsung’s design language and feature set on top of these Android 17 foundations, giving Galaxy users a distinct experience that emphasizes ease of use, visual polish, and deep integration across the Samsung ecosystem.

Potential issues with the beta

As with any beta release, there are bound to be some issues. Users have already reported minor stutters and occasional app crashes in early impressions on forums. Battery drain is also common during the first few days after a major update, as the device re-optimizes apps and background processes. Samsung advises users to be patient during this indexing period and to provide feedback through the Samsung Members app to help iron out bugs.

It is also important to remember that not all apps may be compatible with Android 17 right away. Banking apps, in particular, sometimes lag behind due to stricter security requirements and compatibility checks. Google Play Protect and Samsung’s own app optimization should help, but users may need to wait for app developers to release updates.

How to prepare for the beta

Before installing the One UI 9 beta, be sure to back up your device. Samsung’s Smart Switch app can create a full backup to a PC or external storage, and you can also back up to Samsung Cloud. It is also a good idea to take note of any critical data that you cannot afford to lose.

If you experience serious issues, you may be able to roll back to the stable Android 16 / One UI 8 version. However, rolling back often requires a full factory reset, so it should be done only after backing up your data. Samsung also recommends flashing the official firmware using a PC if you are comfortable with manual rollback procedures.

Availability in other markets

For now, the One UI 9 beta is confirmed only for the US, India, and South Korea. Galaxy S24 owners in the UK, Europe, and other regions will have to wait and see if Samsung expands the rollout. Historically, Samsung has expanded beta programs to more countries over time, so it is likely that more regions will be added in the coming weeks.

In previous years, Samsung’s beta program has reached countries such as the UK, Germany, Poland, and Vietnam. Beta participants typically need a Samsung account and must be willing to provide diagnostic feedback. Samsung also limits the number of participants in each country, so if you are interested, it is best to enroll as soon as possible once the beta becomes available in your region.

The future of Galaxy software

Samsung’s decision to bring the One UI 9 beta to the Galaxy S24 series so soon reinforces its commitment to fast and broad software support. This is particularly important for users who want to keep their devices up to date without having to purchase the latest model every year. The move also puts pressure on other Android manufacturers to step up their update game, as Samsung continues to lead the industry with seven years of promised updates and a robust beta ecosystem.

The Galaxy S24 series is still widely used in 2026, and this update breathes new life into these devices. As the stable release of One UI 9 approaches, S24 owners can look forward to a refined, secure, and feature-rich experience that matches many of the capabilities found on the newer Galaxy S25 and upcoming Galaxy S26 series.

If you own a Galaxy S24, S24 Plus, or S24 Ultra, and you are comfortable with beta software, the wait is over. Head to the Samsung Members app, sign up for the beta, and start exploring what Android 17 has to offer on your Galaxy device today.
