What’s new in One UI 8 Update?

Samsung promises new features and improvements with each major Android OS upgrade. However, their relatively recent move to One UI 8 has raised some eyebrows in the tech community. Before we explore the new features, it’s worth noting that Samsung has been facing criticism over its One UI 7 rollout. Many users have experienced lengthy delays in receiving the update, creating frustration among Samsung’s loyal customer base. Against this backdrop, Samsung has been simultaneously developing One UI 8, based on Android 16. Some suggest Samsung may skip Android 15 and directly jump onto Android 16 for some devices later this year.

✅ Initial Impressions

After watching an early One UI 8 version running on the Galaxy Z Flip 6, it appears this update might be more modest than the version number suggests. Let’s dive deep into what’s new, what’s missing.

Based on early hands-on video, One UI 8 appears to be a surprisingly minimal update. In fact, some have suggested Samsung may have simply rebrand what would have been One UI 7.1 as One UI 8.0.

One UI 8 installed on the Galaxy Z Flip 6, the software is still in its early stages—possibly an internal build rather than a public beta.

While the overall user interface remains largely consistent with One UI 7, there are some subtle changes. For instance:

  • The build is based on Android 16, aligning One UI 8 with the next major version of Android.
  • Navigation options like gesture controls are still intact and unchanged.
  • Animations and overall performance remain smooth and familiar.
  • Some quick settings panel buttons now feature shading (though this could be a bug rather than an intentional design change)
  • The Gallery app has been updated with encircled menu options for a more aesthetically pleasing look
  • Various minor visual tweaks throughout the system.

🖥️ UI Layout & Quick Panel

Surprisingly, the Quick Panel and Notifications area remains largely unchanged from One UI 7. Despite hopes for increased customization, features like the ability to remove or reconfigure certain toggles are still missing. Dex support is also not available for the Z Flip 6 in One UI 8, although it remains supported on devices like the Fold and S Ultra series that traditionally support desktop-mode functionality.

The vertical scroll for the app drawer remains the same, with no apparent tweaks. Swiping and animations also seem to maintain the same smoothness as One UI 7, indicating no significant performance shifts—at least in this early version.

🧠 Galaxy AI and Now Brief

One of the most notable additions is the “Now Brief”, part of Samsung’s Galaxy AI suite. Although this feature was absent on the S24, Fold, and Flip in One UI 7, it is now fully integrated into One UI 8. The Now Brief widget can be enabled from Settings > Galaxy AI > Now Brief, confirming it works similarly to how it does on the Galaxy S25. The One UI 7 does not include Now Brief for the Galaxy S24 series. The One UI 8 may include it by default for all.

Interestingly, the underlying code for this feature already exists in One UI 7, but it will only become functional on older devices with the One UI 8 update.

🎥 Camera Improvements: Pro Video & Log Format

One of the more exciting new features is the Log Video recording option in the Pro Video mode. This professional-grade feature offers a cinematic look, leveraging the flexible form factor of the Z Flip 6 to mimic a tripod-like shooting experience. It offers enhanced dynamic range and more flexibility in post-production.

The toggle for Log video appears under Advanced Video Settings, and it’s expected to be available on other devices like the Fold 6 and Fold Special Edition.

Single Take, the new pre-recording capability found in the S25 series is not present here.

📁 App UI Updates: My Files & Gallery

A noticeable UI refinement comes through in Samsung’s My Files and Gallery apps. The My Files app now uses larger, more simplified tiles for folders, moving away from the denser layout seen in One UI 7. It’s a small but thoughtful visual update that helps with navigation and readability.

Similarly, the Gallery app has a more organized menu structure. Comparing One UI 7 and One UI 8 side-by-side, the new version appears cleaner and more intuitive. Under Gallery Labs, some features like a search tab or mirror screen & viewer appear inconsistently between versions, indicating they might be in development or staged for future rollout.

App versions also differ:

  • One UI 7 Gallery: Version 15.6
  • One UI 8 Gallery: Version 15.7.H

⚡ Quick Share Overhaul

Samsung is making big changes to Quick Share, introducing a more seamless and user-friendly interface. Now, users can:

  • Access send and receive modes directly from the Quick Share menu.
  • Make the device temporarily visible to others, simplifying file transfers without setting a fixed time like the previous “visible for 10 minutes” option.
  • Select files within the Quick Share app itself, without needing to navigate through different apps.

These enhancements make Quick Share more competitive with Apple’s AirDrop, and a better integrated part of the Samsung ecosystem.

The improved visibility controls allow users to make their device temporarily visible to others when needed—a significant improvement over the previous options that limited visibility to either permanent or brief 10-minute windows.

🛠️ Advanced Features & Labs

In the Advanced Features section, specifically the Labs area, most items like allowing apps on the cover screen remain unchanged from previous versions. However, given the early nature of this One UI 8 build, it’s expected that more Labs features will appear in future releases.

🗓️ One UI 8 Timeline and Availability

According to insider information, Samsung could roll out One UI 8 to existing devices within the next three months. The Galaxy Z Fold 7 and Galaxy Z Flip 7 will launch with One UI 8 preinstalled, serving as the debut devices for this update.

Interestingly, there are rumors that Samsung might skip the public beta testing phase for One UI 8, potentially rushing it to market. This could be a response to the criticism over the slow One UI 7 rollout, or it might indicate that the changes are incremental enough that extensive testing isn’t deemed necessary.

Should You Be Excited?

If you’re currently using a Samsung device with One UI 7, the upgrade to One UI 8 will likely bring some welcome refinements, particularly if you’ve been eyeing features like log video recording or the improved Quick Share functionality. However, this doesn’t appear to be a revolutionary update that will dramatically change your user experience.

For those considering a new Samsung device in 2025, the preloaded One UI 8 will offer the most polished experience, but it shouldn’t be the sole deciding factor in your purchase decision.

📌 Conclusion

This early hands-on with One UI 8 showcases incremental refinements rather than groundbreaking changes. Samsung is focusing on UI polish, AI integration, and user-centric updates like Quick Share and camera enhancements. While many features are borrowed from One UI 7 or the Galaxy S25 series, the consistency and forward-thinking design language indicate Samsung is preparing One UI 8 to launch faster and more efficiently than previous iterations.

Download One UI 8

The One UI 8 firmware leaked earlier this week, showcasing the entire next-gen software update from Samsung Galaxy devices. The firmware is for the Galaxy S25 and can be flashed using the unofficial Odin tool.

The One UI 8 firmware is up for the Galaxy Z Flip 6! Devs may use it to port it for other Samsung devices.

Unfortunately, Samsung is sending take down requests for the leaked One UI 8 ROM, which is for internal testing only, that has been floating around in the Samsung community. So we won’t be able to upload the ROM just yet. Perhaps, when the dust has settled down, we will be able to upload the full ROM for all you to enjoy or port it to other devices, just like developers did for the Galaxy S8 and Galaxy S10.
