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

by

The Samsung One UI 8 New Update 2025 is the most awaited update by the fans of Samsung, but now that second beta is released. I put one UI 8 Beta 2 on my S25 Ultra to check what has changed, what has been improved and how does it all happen in the real life.

In case, you have been wondering whether this update is worth your time, here is a list of all the new features, appearance and effects on the reality. I will mention even the minor details, in order to have a clear idea of what you may expect when this update arrives to your device.

Build Details and What’s Inside

When I flashed One UI 8 Beta 2, the build number had an ending that was ZYF3. This is an indication that it is the last live beta to tester. Introduced together with it is the June 2025 security patch which keeps me at ease with the most current patches and security updates.

Here’s a quick summary of the basics:

  • The Build number is ended with ZYF3.
  • Download size: In about 1.2 GB
  • Security_means June 2025 patch

Visual and UI Changes in One UI 8 Beta 2

Samsung One UI is known to have a clean look along with software jammed full of features. It appears that in this beta they focus on small details that would contribute to the greater, more uniform and pleasant experience.

Widgets Back to Normal Size

The very first change that I will notice after resuming the updating: the widgets are now back in the right place. On Beta 1 the widgets were strangely huge, particularly in comparison with what you saw in the stable variant or even on my S24 Ultra. This was giving home screens an off-balance, and wasted space appearance.

Widget Size Key Points:

  • Beta 1: Big unmatched widgets which did not fit older versions.
  • Beta 2: Widgets go back to normal as opposed to stable releases and S24 Ultra.
  • You get neater and more recognized home screens.

Longer Haptic Feedback on Live Notifications

Haptic feedback, which is the slight vibration, that you get when you touch a notification, is very different now in Beta 2. Previously, a light tap on a live notification resulted in light tick (just like on the stable version).

VersionHaptic Feedback
StableQuick, light tick
Beta 1Same as Stable
Beta 2Longer vibration

This change provides a greater tap to feel and tap response. It is that sort of detail that renders a phone a premium one.

Thicker Quick Settings and Notification Banners

There has also been facelifting of quick settings. The slider of brightness, the controls and the outputs of the devices look and feel bushy. The banners of notification are thicker, which makes them easier to notice and to be read.

Visual Consistency Improvements:

  • A thicker brightness slider with more simple interface.
  • Control buttons of the weapons and the media produce are more enhanced.
  • These notification banners are more convenient to read.

Taken together, however, it is obvious Samsung is trying to refine the appearance and performance of items to every day users.

Share Sheet Animation and Visual Tweaks

Sharing has not been left out by Samsung. When you choose photos and tap share now, a different animation happens: the chosen images are pulled in the sides of the screen before the share menu will be present. It is smoother and much cleaner in look.

Share Sheet UI Tweaks:

  • new animation when share multiple items.
  • Bold out line on “modify” button so you can not miss it.
  • Cleaner separators are helping out making it simpler to spot sharing targets.

All this combined results make implementing that bit easier to share and share seamlessly.

Updated Settings and Tips Experience

The settings have the center stage of our interaction with our cell phones. The Samsung One UI 8 New Update 2025 touches up this key section of the system in several ways that make a fair bit of difference.

Tips and User Guide—A Smarter Help Section

What was formerly referred to as User Guide at the bottom of settings has been renamed Samsung in Samsung. It has changed its name to Tips and User Guide. Rather than taking you to a web page, Samsung created a valuable in-app guide that is literally part of One UI 8 Beta 2.

Inside, you’ll find:

  • There was a special banner on top of Galaxy AI feature highlights.
  • Visual instructions and simple manuals on the use of new features.
  • A hygienic manner through which one can go through this and experience what is new in this update.

To anyone who has just switched to Samsung or someone who wants to utilize all the possibilities of his smartphone to the maximum, this update is highly appreciated.

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

In the app Tips and User Guide there is a new section What is new in 1 UI 8. There are two major new features to quality of life:

  1. Simply find Easier Feedback: You can now easily leave your feedback directly to Samsung directly in Samsung Members One UI Beta community. This makes the bugs reporting fast and assists in making the end result be of better benefit to all.
  2. Improved Galaxy Buds support: Galaxy Buds integration is going to be better as when you connect them, a new option will appear with the title right at the top of your settings screen. This allows you to modify Buds settings without opening the additional Galaxy Wearable app. It is several notches quicker when it comes to manipulating the sound, controls, and fit.

You can navigate the updated tips app thanks to visual aids and simple language explanations all over to trained, especially in the old web only version.

Samsung Dex Gets a UI Refresh

It also paid attention to Samsung Dex, which has transformed the phones into desktop working stations. The new Dex menu has a more recent look that provides more transparent designs. When I used Dex on an external screen, I did not observe my functional changes, although the menus appear and operate better. This is supposed to smoothen the use of multitasking, particularly to those who rely on Dex in working.

Animation and Performance Upgrades

The process of opening apps in the One UI 8 is slightly different than in One UI 7. In this beta, animations are a bit slower, which could be seen mostly around the corners of the app as these corners grow. Although this additional moment of a split second may not seem to be significant, it makes the visual flow a little smoother.

Animations: New Look, Different Pace

The process of opening apps in the One UI 8 is slightly different than in One UI 7. In this beta, animations are a bit slower, which could be seen mostly around the corners of the app as these corners grow. Although this additional moment of a split second may not seem to be significant, it makes the visual flow a little smoother.

Animation Experience:

  • One UI 7: Snappier, hardly any delay while launching apps.
  • One UI 8 Beta 2: More smooth, yet slightly slower to start the apps (at the corners especially).

And, in case you are in love with buttery-smooth transitions, than this method may be to your liking, but again, you may skip this as speed is everything to you.

Performance: Stability and Speed

I tested Beta 2 and opened and closed apps several times. I did not encounter UI bugs, or other weirdnesses. It is all easier and sleeker and compared to Beta.

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

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

They are comparable to the stable February 2025 version, which implies that daily use is still as fast as before. In regards to the battery life, I have only just installed this build before shooting and thus I am unable to pass a conclusive judgement on this factor. Should I find that big changes are taking place, I shall certainly report this to you later.

Long List of Bug Fixes and Cleanups

Samsung invested much effort in disappearing remaining bugs and improving the experience with greater reliability. In the event that you experienced some weird stuff in Beta 1, you are likely to find them listed in this category.

Key Bug Fixes in One UI 8 Beta 2:

  • At the moment Brief Text Alignment: Fixed text does not align properly.
  • Morning Briefing Screen: Issue about the screen remaining on, when it should not, has been solved.
  • Battery Widget Icon: The image of the battery widget is brighter and clearer to be in one line with the other widgets.
  • Lock Screen Widget Size: The bug that saw the size increase in Beta 1 was also fixed and it should fit as expected.
  • File Movement Errors: File movement has become reliable and those using Secure Folder are most affected.
  • Bluetooth Call Volume: The phone no longer cuts down your volume when you are using Bluetooth call in your car.
  • Game Notification Sound: The notification sounds would now be correctly played during the gaming process.
  • Galaxy AI Weather and Time Wallpapers: Such wallpapers do not run into any errors and non-working problems anymore.
  • Gesture Navigation: Users no longer issue with fixing the issue in which the back gesture stopped working.
  • S Pen Air Command: It so happens that the Air Command icon does not leave your screen anymore even when you remove your S Pen.
  • Alarm Sound: If you did not make an update of the clock application after getting the beta, then the alarm will go as usual.
  • Overall Software Update: Most of the applications such as the camera were also updated to make them smoother and stable.

The size of the update file: about 1.2 GB, which is huge but presupposes numerous changes in the background in addition to these visible corrections.

Conclusion

The Samsung One UI 8 New Beta 2 in Beta 2 is not about the shiny new features nobody needs, it is about polishing the experience and ensuring basic things feel proper. My S25 Ultra is polished and bug-free with smaller widgets, thicker controls, more pleasing share sheets, a more intelligent tips app, and plenty of bug quashing.
