One UI 8 Beta 2 on Samsung S25 Ultra New Features, Bug Fixes, and What’s Improved in 2025

Samsung fans have been waiting for the latest update, and now the Samsung One UI 8 New Update 2025 is here in its second beta. I installed One UI 8 Beta 2 on my S25 Ultra to see what’s new, what’s fixed, and how it all feels in real life. If you’ve been asking yourself whether this update is worth it, let’s check out every new feature, visual change, and real-world impact. I’ll point out even the small details, so you know exactly what to expect when this update hits your device.

Build Details and What’s Inside

When I installed One UI 8 Beta 2, the build number ended with ZYF3. This signals it’s the latest beta for testers. Alongside that, the build brings the June 2025 security patch, giving me peace of mind with the most recent fixes and security improvements.

I loaded the build manually, so I can’t say how big the OTA update will be when you get it. However, reports put the update size around 1.2 GB. With a beta this size, you can expect more than just tiny fixes. Samsung’s focused on smoothing out rough edges, adding polish, and bringing a safer experience.

Here’s a quick summary of the basics:

• Build number: Ends with ZYF3
• Update size: About 1.2 GB
• Security: Includes June 2025 patch

Visual and UI Changes in One UI 8 Beta 2

Samsung One UI has a reputation for both clean visuals and feature-packed software. In this beta, the focus seems to be on “little things” that add up to a more consistent and enjoyable experience.

Widgets Back to Normal Size

The first thing I noticed after restarting the update: widgets are finally back to looking right. In Beta 1, widgets were oddly oversized, especially when compared to what you saw on the stable version or even on my S24 Ultra. This made home screens look off-balance and wasted space.

Now, after installing Beta 2, widgets snap back to regular proportions. You’ll appreciate the symmetry if, like me, you care about how your home screen lines up.

Widget Size Key Points:

• Beta 1: Widgets too large and didn’t match older versions.
• Beta 2: Widgets return to normal, matching stable releases and S24 Ultra.
• Results in a neater, more familiar look for your home screens.

Longer Haptic Feedback on Live Notifications

Haptic feedback—or the little buzz you feel—when interacting with notifications is now noticeably different in Beta 2. Earlier, tapping a live notification only gave a light tick (similar to the stable version).

Now, I feel a longer and stronger vibration when tapping. It’s subtle but makes actions feel more defined.

Version	Haptic Feedback
Stable	Quick, light tick
Beta 1	Same as Stable
Beta 2	Longer vibration

This change gives a more satisfying and confident tap experience. It’s the kind of small touch that makes a phone feel premium.

Thicker Quick Settings and Notification Banners

Quick settings have received a facelift too. The brightness slider, device controls, and media output sections look and feel thicker. Notification banners are chunkier, making them stand out more and improving legibility.

This not only looks better, but for me, small design tweaks like this make the targets easier to hit with my thumb. Quick settings feel more distinct and accessible.

Visual Consistency Improvements:

• Brightness slider now thicker and easier to use.
• Device control and media output buttons are more pronounced.
• Notification banners are easier to read at a glance.

Seeing these changes together, it’s clear Samsung is working to polish how things look and work for everyday users.

Share Sheet Animation and Visual Tweaks

Samsung hasn’t forgotten about sharing either. Now, when you select photos and hit share, a new animation plays: the selected images pull together from the edges of the screen before the share menu appears. It looks much cleaner and smoother.

Sharing from third-party apps like Google Photos also gets subtle updates. The “modify” button, for example, uses a bolder outline, and separators between app icons stand out more.

Share Sheet UI Tweaks:

• New animation when sharing multiple items.
• Bold outline for “modify” button so you don’t miss it.
• Clearer separators make it easier to distinguish sharing targets.

Altogether, these small changes make sharing that little bit more engaging and seamless.

Updated Settings and Tips Experience

Settings are at the heart of how we interact with our phones. The Samsung One UI 8 New Update 2025 brings some much-needed clarity and improvements to this core part of the system.

Tips and User Guide—A Smarter Help Section

Samsung has renamed what used to be “User Guide” at the bottom of Settings. Now, it’s called Tips and User Guide. Instead of sending you out to a web page, Samsung built a helpful in-app resource right inside One UI 8 Beta 2.

Inside, you’ll find:

• A dedicated banner at the top for Galaxy AI feature highlights.
• Visual guides and easy-to-follow text on using new features.
• A clean way to browse and learn about what’s new in this update.

For anyone new to Samsung or those wanting to make the most out of every feature, this update is very welcome.

What’s New in One UI 8—Faster Access to the Latest Features

Within the Tips and User Guide app, there’s a new “What’s New in 1 UI 8” section. Two big quality-of-life improvements stand out:

1. Easier Feedback: Now you can quickly share your thoughts straight with Samsung in the Samsung Members One UI Beta community. This speeds up bug reporting and helps make the final release better for everyone.
2. Better Galaxy Buds Integration: If you connect Galaxy Buds, you’ll see a new menu item appear right near the top of your Settings page. This lets you adjust Buds settings directly without opening the separate Galaxy Wearable app. It’s a much faster way to tweak sound, controls, and fit.

The visual guides and clear explanations throughout the updated tips app make learning easier, especially compared to the old web-only version.

Samsung Dex Gets a UI Refresh

Samsung Dex, known for turning phones into desktop workstations, also got some design attention. The updated Dex menu sports a fresher look with clearer layouts.

When I tested Dex on an external display, I didn’t see functional changes, but the menus look and work better. This should make multitasking a little smoother, especially for users who rely on Dex for productivity.

Animation and Performance Upgrades

Nobody likes a slow phone, and smooth animations can make a world of difference in daily use. Here’s how Samsung tackled performance and visual flow in the One UI 8 Beta 2.

Animations: New Look, Different Pace

Opening apps on One UI 8 feels a bit different compared to One UI 7. Animations in this beta are slightly slower, especially noticeable around the app’s corners as they expand. While this extra split second might seem minor, it creates a slightly more graceful visual flow.

Animation Experience:

• One UI 7: Snappier, almost instant app openings.
• One UI 8 Beta 2: Smoother, but just a touch slower on app launch (particularly at the corners).

If you love buttery-smooth transitions, you might prefer this approach, though if speed is everything for you, it’s something to keep in mind.

Performance: Stability and Speed

I put Beta 2 through its paces by opening and closing apps repeatedly. I haven’t hit any UI glitches or strange behavior. Everything runs smoother, and unlike Beta 1, I didn’t spot any hiccups filming for the video.

For those who love benchmark numbers, here are my results:

• Geekbench Multi-Core Score: ~9,300
• Geekbench Single-Core Score: ~2,900

These are on par with the stable February 2025 release, which means daily use remains just as quick as before.

As for battery life, I just installed this build before filming, so it’s too soon for a final verdict. If I notice big changes, I’ll be sure to share my findings later.

Long List of Bug Fixes and Cleanups

Samsung put a lot of work into tackling leftover bugs and making the experience more reliable. If you suffered from strange behaviors in Beta 1, you’ll probably find they’re sorted here.

Key Bug Fixes in One UI 8 Beta 2:

• Now Brief Text Alignment: Fixed text not lining up correctly.
• Morning Briefing Screen: Resolved issue with the screen persisting when it shouldn’t.
• Battery Widget Icon: Brighter, clearer icon in line with other widgets.
• Lock Screen Widget Size: Fixed the size increase bug from Beta 1; now fits as expected.
• Fingerprint Recognition: Patched issues where fingerprint unlock would intermittently fail or throw errors.
• File Movement Errors: Moving files now works as expected, especially for those using Secure Folder.
• Bluetooth Call Volume: The phone no longer drops your volume during Bluetooth calls in your vehicle.
• Game Notification Sound: You’ll now hear notification sounds properly during gaming sessions.
• Galaxy AI Weather and Time Wallpapers: These wallpapers no longer run into errors or non-functioning issues.
• Gesture Navigation: Fixed problems where the back gesture would stop working.
• S Pen Air Command: The Air Command icon now stays put when you detach your S Pen.
• Alarm Sound: If you didn’t update the clock app after installing the beta, the alarm will still ring as expected.
• General Software Updates: Many apps, including the camera, received updates for stability and smoothness.

Update File Size: Around 1.2 GB, which is sizable and hints at lots of background improvements along with these visible fixes.

I noticed that after installing Beta 2, everything feels snappier and noticeably more stable. It’s a step forward towards a polished, final version.

Conclusion

The Samsung One UI 8 New Update 2025 in Beta 2 isn’t about adding flashy new features no one asked for—it’s about fine-tuning the experience and making sure the basics feel right. With resized widgets, thicker controls, smoother share sheets, a smarter tips app, and loads of bug fixes, my S25 Ultra feels polished and reliable.
