Samsung Pushes One UI 8 Beta 6 Update for Galaxy S25 Series with September 2025 Security Patch

Samsung has been consistent with its One UI Beta program for years, and the Galaxy S25 series is once again at the center of attention. The company has officially rolled out the One UI 8 Beta 6 update to its flagship smartphones, giving testers a better experience ahead of the stable release. The update bears the build version ZYHB and weighs approximately 800MB, which indicates a fairly significant package that not only fixes existing problems but also adds fresh improvements.

What makes this release more exciting is the inclusion of the September 2025 security patch, making the Galaxy S25 series the very first to receive Samsung’s newest security enhancements. With this update, Samsung further tightens device protection while also polishing the overall Android 16 + One UI 8 experience.

Let’s break down everything you need to know about this new Beta update, including fixes, improvements, availability, and what it means for the future stable rollout.

What’s New in One UI 8 Beta 6?

Samsung has been refining One UI 8 since its first Beta release, and Beta 6 represents one of the most stable and polished versions yet. It directly tackles six major issues that early testers had been facing, while also enhancing core functionality.

Here’s a detailed breakdown of the changelog:

1. Lock Screen Notification Fix

One of the most frustrating bugs in previous Betas was related to the lock screen notifications. Instead of showing notification previews, the lock screen was only displaying app icons. This made it difficult for users to quickly glance at their notifications.

Beta 6 fixes this issue, ensuring users once again get the full notification preview experience on the lock screen—an essential feature for daily usability.

2. Naver Sports Notification Issue Resolved

In South Korea, Naver Sports is a widely used app for live sports updates. However, users had reported issues where the Now Bar live notifications were being cut off, making them unreadable.

With Beta 6, Samsung has resolved the app logo truncation issue, ensuring that Naver Sports users can once again enjoy seamless real-time sports updates without missing any details.

3. Samsung Keyboard Phrase Recommendation Fix

The Samsung Keyboard is a powerful tool with predictive typing and smart phrase recommendations. Unfortunately, in earlier builds, the suggested replies and recommendations feature became buggy after a device reboot.

Beta 6 addresses this, ensuring that phrase recommendations and suggested replies now work smoothly even after restarting the phone. This makes the keyboard far more reliable for communication.

4. System Font Customization Restored

Personalization is one of Samsung’s biggest selling points, and many users love changing their system fonts. However, Beta testers were facing an issue where font customization options inside Settings simply didn’t work.

With Beta 6, this problem has been fixed. Users can once again change fonts system-wide, maintaining Samsung’s promise of giving One UI the most customizable Android skin experience.

5. Home Screen Widget Enhancement

Samsung’s widgets backed by Personal Data Intelligence activity had a frustrating bug where certain characters were being truncated or cut off.

Beta 6 modifies this core component, ensuring that widgets display information properly without missing text. This not only improves usability but also ensures the widgets align better with One UI 8’s polished design language.

6. Display & Clock Widget Improvements

Another issue reported by users was the display interface freezing in certain conditions, leaving the lock screen stuck in the background. Additionally, some users noticed that the clock widget time display was inaccurate.

Both of these issues have been resolved in Beta 6, leading to a smoother lock screen experience and more reliable clock functionality.

Security Enhancements: September 2025 Patch

Apart from bug fixes, the highlight of Beta 6 is the addition of the September 2025 security patch. Samsung has become one of the leaders in timely Android security updates, often releasing patches even before Google.

This patch includes important vulnerability fixes, strengthening the protection against potential exploits. While the exact details of the patch will be published in Samsung’s monthly security bulletin, Galaxy S25 users can rest assured that their devices are ahead of the curve in security.

Regions Where One UI 8 Beta 6 Is Rolling Out

As of now, the update is already available in Germany, India, South Korea, and the UK. Two more major markets, Poland and the US, are also expected to begin rolling out the update shortly.

This wide availability indicates that Samsung is close to finalizing One UI 8 for stable release. Typically, once the Beta hits this level of polish, the official rollout follows within weeks.

How to Download and Install One UI 8 Beta 6

If you are already part of the Samsung Members Beta Program, installing the update is straightforward:

1. Open Settings on your Galaxy S25 series device.

2. Scroll down and select Software update.

3. Tap Download and install.

4. Wait for the 800MB package to download and complete installation.

Since this is a Beta release, it’s recommended to back up important data before installation. While Beta 6 is stable, minor bugs may still exist.

Why One UI 8 Beta 6 Matters

Each Beta release is a step closer to the final stable One UI 8 release, which is expected to debut officially in September 2025. The fact that Samsung is ironing out specific app issues, lock screen glitches, and personalization limitations shows the company’s commitment to user feedback.

For Galaxy S25 series owners, this Beta provides a glimpse of the future stable release while also ensuring smoother daily usability. Moreover, with the September 2025 security patch, testers are actually ahead of many other Galaxy users in terms of security.

Expected Stable Release Timeline

Looking at Samsung’s history, the stable One UI 8 release for the Galaxy S25 series should begin rolling out by late September 2025. Other devices in the Galaxy lineup will follow in stages, depending on regions and models.

The fact that Beta 6 is now widely available means Samsung is nearly done with bug fixes and optimizations, making the official rollout imminent.

Final Thoughts

The Samsung Galaxy S25 series One UI 8 Beta 6 update is one of the most important pre-release builds yet. With six major fixes, widget improvements, personalization restorations, and the September 2025 security patch, it marks a turning point where the Beta feels more like a stable release candidate.

If you are a Beta tester, you should definitely update to Beta 6 to enjoy the smoother and safer experience. If not, the wait isn’t long—Samsung is expected to begin the official rollout in September.
