Samsung continues its One UI 9 beta program for the Galaxy S26 series, releasing a fifth beta build that packs the August security patch and a long list of stability improvements. The update arrives after a month-long gap and follows the stable launch of One UI 9 on the Galaxy Z Fold 8 and Flip 8, which has left many flagship owners wondering when their devices will get the final version.

The fifth beta, identified by a build number ending in ZZH6, began rolling out to users in Korea and India, according to tipster Tarun Vats. A matching build has also been spotted in the UK, indicating that Samsung is preparing a wider release. The update size is around 1,125MB, typical for a beta that includes both feature refinements and security improvements.

What the latest beta fixes

The changelog focuses on resolving performance-related issues across several core applications and system UI elements. Users have reported that the update improves an issue where the Settings app would freeze or display a white screen in certain menus. Similarly, Samsung has addressed a problem where launching the camera widget from the lock screen resulted in slow performance or a black screen.

Other notable fixes include corrections to the bottom floating bar in the Phone app, which was not displaying correctly. The update also resolves a temporary blank screen that appeared when entering the recent files list in the My Files app. Home screen customization is improved as well, with 1x1 size shortcuts now being correctly added to the bottom bar.

Additional improvements

• Fixed misaligned or flickering preview screens in the Video Editor and Photo Editor.
• Addressed intermittent screen flickering in certain situations.
• Resolved Wi-Fi connection errors and enhanced connection stability.

A longer-than-expected beta cycle

Samsung originally launched the One UI 9 beta program for the Galaxy S26 series in June 2026, shortly after unveiling the new software at its annual developer conference. The beta program was meant to run for about a month before the stable rollout, but the schedule has slipped. The fourth beta arrived in mid-July, and the fifth has only now landed in August, leaving a clear gap that suggests Samsung is taking extra time to polish the experience.

One possible reason for the delay is the sheer number of changes coming to One UI 9. The update is one of the biggest overhauls in recent memory, introducing a redesigned notification panel, new lock screen customization options, and a revamped camera app interface. Samsung has also been working on optimizing battery life and performance, which requires extensive testing across multiple hardware configurations.

Additionally, Samsung has been balancing the beta program for the S26 series with the stable release that debuted on its latest foldable devices. The Galaxy Z Fold 8 and Flip 8 shipped with One UI 9 out of the box, and feedback from those devices has likely helped Samsung refine the software before pushing it to older flagships.

What to expect from One UI 9 stable

While Samsung has not provided an official timeline for the stable One UI 9 release on the Galaxy S26 series, the company typically waits until the beta program has reached a mature state. Historically, Samsung has released stable updates to beta participants first, followed by a broader rollout to all users in key markets like Korea, the US, and Europe.

Given that this is the fifth beta, it is reasonable to expect that the stable build is not far away. The inclusion of the August security patch suggests that Samsung is preparing the build for a commercial release, as betas often receive the latest security patch at the end of the testing cycle. However, some users have already expressed frustration over the extended wait, especially since the company’s newest foldables are running stable One UI 9 while last year’s flagship continues to receive beta builds.

The Galaxy S26 series launched in early 2026 with One UI 8 based on Android 16. One UI 9 is expected to bring Android 17 to the devices, along with Samsung’s own feature additions. The update has been in development for several months, and the company is likely aiming to ensure that performance and battery life are up to par before flipping the switch.

How to get the beta

Users in supported regions can sign up for the One UI 9 beta program through the Samsung Members app. Once enrolled, the beta update will appear in the device’s software update menu. It is worth noting that beta builds can contain bugs, and Samsung typically recommends that users install beta software on secondary devices only.

As with previous beta releases, the fifth beta is expected to roll out in phases. Users in Korea and India have already received it, and the UK build has been spotted as well. Availability in other regions, including the US, may follow in the coming days. Interested users should keep an eye on the Samsung Members app for notifications.

The broader Android community is also watching the One UI 9 rollout closely, as Samsung’s software decisions often influence other Android OEMs. The company’s approach to One UI 9 — from its extensive customization tools to its performance optimizations — has generally received positive feedback from beta testers, despite the occasional hiccup that each new beta aims to fix.

The importance of security patches

One of the most critical components of this latest beta is the inclusion of the August 2026 security patch. Samsung has been known for its prompt monthly security updates, and the beta program is no exception. Keeping devices up to date with the latest security patches is essential for protecting against vulnerabilities, especially as mobile threats continue to grow.

The August patch addresses a number of security issues, including several found in the Android operating system and Samsung’s own software. While the full details are typically published on Samsung’s security bulletin page after the stable release, beta users are already receiving the benefits. This also reassures users that the final stable build will ship with the latest protections built in.

Where Samsung goes from here

Looking ahead, Samsung’s next steps will involve releasing more beta builds if additional issues are found, or pivoting to the stable rollout. Given the pattern of previous One UI versions, the sixth beta is unlikely unless a major problem emerges. The company will likely release a stable version within the next few weeks, starting with beta participants and then expanding to all Galaxy S26 users.

For owners of older devices, the wait will be longer. Samsung typically prioritizes its newest flagships, and the Galaxy S25 series is expected to receive One UI 9 stable after the S26 series. Other high-end devices, such as the Galaxy Z Fold 6 and Flip 6, along with the Galaxy Tab series, may see the update later in the year.

In the meantime, Galaxy S26 users who are not enrolled in the beta program will need to be patient. Samsung has not announced a specific date for the stable rollout, but the company’s usual release cadence suggests that it should arrive before the end of September. Until then, the beta program remains the best way to get an early look at One UI 9 and help Samsung iron out the remaining issues.

The fifth beta is a clear step forward, and the fact that Samsung is adding the latest security patch indicates that the software is approaching production quality. Once the stable version drops, Galaxy S26 users will finally be able to enjoy One UI 9 without the beta stigma. Until then, beta testers can continue to provide valuable feedback that will shape the final release.
