The announcement was made through a notice in the Samsung Members app, which confirmed that the next beta build is scheduled for next week, likely between August 18–23, 2025. While no exact date has been provided, Samsung has reassured beta participants that the update will focus primarily on stability improvements and refining system performance.

With the official release planned for next month, this upcoming beta could be a crucial turning point for Samsung in deciding whether the software is stable enough for a public rollout or if more refinements are needed.

Recap: Samsung’s One UI 8 Beta Journey So Far

To understand the significance of Beta 5, let’s quickly recap Samsung’s beta journey for the Galaxy S25 lineup:

  1. Beta 1 (May 2025):
    The very first One UI 8 beta for the S25 series introduced the core Android 16 features, along with Samsung’s design refinements, smoother animations, and new AI-driven improvements.

  2. Beta 2 (June 2025):
    Samsung refined system responsiveness, fixed bugs, and improved Galaxy AI integration. This build also patched several stability issues reported by early adopters.

  3. Beta 3 (Early July 2025):
    Focus shifted towards battery optimization, camera stability, and enhancements in multitasking.

  4. Beta 4 (Late July 2025):
    This update was almost entirely stability-focused, with minimal feature additions. Samsung aimed to fine-tune performance, optimize RAM management, and reduce app crashes.

Now, with Beta 5 scheduled for rollout next week, Samsung seems to be moving toward finalizing its One UI 8 experience ahead of the official launch in September 2025.

Samsung’s Official Notice – One UI 8 Beta 5

The Samsung Members notice for Galaxy S25 beta testers confirmed the following key points:

  • Beta 5 rollout is planned for next week (no fixed date yet).

  • The update will reflect user feedback collected during the beta testing phase.

  • Stability and performance improvements remain the top priority.

  • If stable, this build could mark the final beta before the public release.

Samsung’s communication through the Members app is a strong indication that development is on track, and the brand is confident about moving closer to a stable release.

What to Expect in One UI 8 Beta 5

While Samsung has not published a detailed changelog yet, based on the One UI beta testing pattern from previous years, we can expect the following refinements in Beta 5:

1. Enhanced Stability

The main highlight will be system stability. Samsung wants to ensure fewer crashes, smoother transitions, and a lag-free experience before the stable release.

2. Refined Galaxy AI Features

Samsung has been pushing AI integration as a major feature of One UI 8. Beta 5 may include more refined AI tools for text summarization, voice transcription, and image editing.

3. Battery Optimization

Battery drain has been one of the top concerns reported by beta testers. Beta 5 could bring better background process management to extend screen-on time.

4. Camera and Gallery Fixes

Previous betas included camera optimizations, but some stability issues still persist. Samsung might introduce fixes for shutter lag, focus inconsistencies, and gallery syncing.

5. Improved App Compatibility

Samsung typically uses later beta builds to refine app performance. Expect third-party app crashes to be reduced.

6. Security Enhancements

Since the August 2025 security patch is already rolling out alongside other beta builds, Beta 5 should include the latest patch integration.

Release Timeline – When to Expect the Update

Samsung has confirmed the update is coming next week, but hasn’t provided a specific date. Based on past beta rollouts, the likely release window is August 18–23, 2025.

  • Week of August 18: Samsung may begin rolling out Beta 5 to Korean users first.

  • Following Days: Expansion to US, India, Germany, and UK is expected.

  • Late August: If the build is stable, Samsung could finalize the stable release candidate for a September launch.

Why Beta 5 is a Crucial Turning Point

The fifth beta build usually acts as a final testing stage before public release. For Samsung, this is the moment to confirm:

  • Is the system stable enough for mass rollout?

  • Are critical bugs eliminated?

  • Can performance match expectations across regions and carriers?

If Beta 5 performs reliably, Samsung will likely skip Beta 6 and move straight to the stable rollout in September. However, if instability persists, an additional beta round might delay the release.

The Road Ahead – Stable One UI 8 Release

Samsung has already confirmed that the Galaxy S25 series will receive the official One UI 8 stable update in September 2025.

Here’s what users can expect after the Beta 5 rollout:

  • Stable Release Candidate (SRC): If Beta 5 proves stable, it will serve as the SRC build, paving the way for global rollout.

  • Wider Device Support: After the S25 series, Samsung will extend One UI 8 to the Z Fold 6, Z Flip 6, Galaxy S24, and older flagships.

  • Public Rollout Begins: September will mark the official distribution phase, starting with South Korea and gradually expanding worldwide.

Final Thoughts

Samsung is clearly on track with its One UI 8 development roadmap, and the Galaxy S25 series is leading the way. With Beta 5 scheduled for rollout next week, users are just weeks away from experiencing the final stable One UI 8 update.

This upcoming beta will be make-or-break — if stable, it could mark the last test phase before the official release. If not, Samsung may need to extend testing slightly, but September remains the target launch window.

For now, Galaxy S25 users should keep an eye on Samsung Members notifications and be ready to install One UI 8 Beta 5 OTA once it becomes available.
