One UI 8 Beta Expansion

Samsung recently started rolling out the One UI 8 Beta 2 update for the Galaxy S25 series in the US, Korea, the UK, and the US. This update fixed several issues that users encountered in the previous beta update.

In addition to the new beta, the company also began the One UI 8 Beta update in Poland and India. Now, these two more countries’ users can enjoy One UI 8 features ahead of the official release. It is expected that more Galaxy devices, including the Galaxy S24 series, the Galaxy Z Fold 6, and the Galaxy Z Flip 6, will soon get this beta update.

One UI 8 Beta 2 hits Galaxy S25 series in Germany, the US and UK – Here’s what’s new

Samsung’s June 2025 security update is now making its way to the Galaxy Z Flip 6, Fold 6, and Fold SE. The three foldable phones released in 2024 are receiving new firmware updates in South Korea with security improvements.

The rollout follows the June patch’s deployment on the Galaxy S25 and Galaxy S24 series. Samsung has also recently released an updated One UI 8 Beta for the S25 series in six markets, opening beta access in India and Poland.

The June 2025 update includes 39 Android CVEs and 19 One UI SVEs. These fixes will improve your Galaxy device’s security status. Users can also expect a more reliable and stable performance and smoother functioning.

Note that the June patch update can be identified through the PDA build versions: F741NKSS2BYER, F956NKSS2BYER, and F958NKSS2BYER for the Galaxy Z Flip 6, Z Fold 6, and Z Fold SE, respectively.

It’s currently live in South Korea, with expansion likely to America and Europe shortly. To check for the updates manually, navigate to the system Settings, followed by Software update, and Download and install.

One UI 8 Beta Prep?

Similar to the Galaxy S24 series, Samsung’s June 2025 security update seemingly readies the Galaxy Z Flip 6 and Fold 6 for the One UI 8 Beta Program. The Special Edition foldable phone may directly receive the Stable One UI 8.

One UI 8 Beta Program may launch for a few more Galaxy devices later this month. Samsung is highly likely to initiate the One UI 8 Watch Beta Program as well. Both announcements may come right before the Galaxy Unpacked.

Installing the Beta firmware unlocks access to Android 16 early. The Stable release may take around two months, while the Beta Program brings the latest software (at the cost of some common yet frustrating bugs) to your Galaxy, instantly.

Samsung has just rolled out the One UI 8 Beta 2 update (build ZYF3) for the Galaxy S25 series, bringing fixes and minor enhancements. This release focuses on fixing bugs and stabilizing the software, making the S25 series smoother and more reliable.

The One UI 8 Beta 2 update is based on the Android 16 operating system, with a download size of 1,204 MB. It includes the June 2025 security patch, which ensures your Galaxy S25 device stays secure with the latest protections.

This article covers the update’s features, bug fixes, and details for Beta Program participants.

New Feature: User Feedback for Interpreter

One UI 8 Beta 2 update adds a user feedback feature to improve interpreter performance. This allows users to share input directly, helping Samsung refine the interpreter tool for better accuracy and usability in future updates.

Bug fixes for a smoother experience

Now Brief text alignment:

This update tackles several issues reported in the first beta. It fixes the Now Brief text alignment and resolves the morning briefing screen persisting longer than intended, ensuring a cleaner and more reliable user interface.

Battery Widget and Lock Screen:

The battery widget icon has been improved for better visibility. Additionally, the update fixes an issue where widget sizes on the lock screen increased unexpectedly, providing a more consistent and polished lock screen experience.

Fingerprint enhancements:

Intermittent fingerprint recognition failures and unlock errors have been addressed. The update ensures smoother and more reliable fingerprint authentication, making unlocking your Galaxy S25 faster and less prone to errors during daily use.

Secure Folder and Bluetooth Call Fixes:

File movement malfunctions in Secure Folder are now resolved with the second Beta update. The update also fixes an issue where the volume lowered during Bluetooth calls in vehicles, ensuring clear audio for calls made on the go.

Notification and Gaming improvements:

The update fixes a bug where no sound was heard when notifications arrived during gaming. This ensures uninterrupted gaming sessions with proper notification audio, enhancing the overall experience for Galaxy S25 gamers.

Galaxy AI and Gesture Navigation Fixes:

Non-functioning errors in Galaxy AI weather and time wallpapers are corrected. The update also resolves an issue preventing users from going back when gesture navigation is enabled, improving navigation reliability.

S Pen and Clock App Enhancements:

The Air Command icon no longer disappears (on Galaxy S25 Ultra) when the S Pen is detached. Additionally, the update fixes an issue where the alarm sound didn’t ring if the Clock app wasn’t updated post-beta.

App Updates and Software Stabilization:

The update includes software stabilization through enhancements to multiple apps, including the Camera app. These improvements optimize performance, reduce crashes, and ensure a smoother experience across the S25 series.

With the Beta 2 rollout, Samsung’s One UI 8 Beta is now available in Germany, India, Poland, South Korea, the UK, and the US.

Samsung starts pushing the June 2025 update to the Galaxy S24 series, which has a surprise One UI 8 Beta tease. While the update’s scope is limited to security enhancements, it makes the devices ready for an imminent OS switch.

The Galaxy S24 series is starting to receive the June 2025 security update in South Korea. The firmware’s rollout has just begun, and Korean users should receive it sequentially.

Last week, Samsung dropped details of its June 2025 security patch. For Android, it contains fixes for over three dozen High-labeled CVEs. Samsung additionally included 19 SVE items to ensure security and privacy on Galaxy devices.

To update your device, jump to Samsung’s Settings > Software update > Download and install.

While S24’s June patch has just landed, Samsung is now widely rolling out the update for the Galaxy S25 series. This firmware has also bumped the bootloader version, giving users strong vibes of a Beta 2 release along with market expansion.

What’s the One UI 8 Beta surprise?

Samsung’s latest Galaxy S24 update tightens security measures by blocking a software rollback. While complete details awaited, it would be tweaking the bootloader version, ultimately barring users from going to a previous build.

Galaxy users often receive firmware updates with such tweaks. However, it’s One UI 8 Beta testing time, and such a change in software mechanism is nothing but a solid hint at an imminent launch of the One UI 8 Beta Program.

Google has recently released the Stable Android 16 update. The new OS introduces plenty of new features, and most of the new additions are set to land on Galaxy devices, thanks to Google and Samsung’s collaborative approach.

Samsung’s Android 16-based One UI 8 Beta Program is currently available for the Galaxy S25 series in the US, UK, Germany, and South Korea, while India and Poland are the most likely candidates once the expansion takes place.

Samsung is preparing to launch One UI 8 Watch, a major software update for its Galaxy smartwatches, based on Wear OS 6. This update promises new features and aims to keep Samsung’s wearable lineup fresh and competitive.

One UI 8 Watch succeeds the One UI 6 Watch

One UI 8 Watch succeeds One UI 6 Watch, skipping One UI 7 Watch entirely. Samsung is aligning its watch software versioning with its smartphone updates, like One UI 8 for phones, for a more unified ecosystem experience.

One UI 8 Watch Update Rollout

• Launch – July 2025 with Watch8s
• Beta – July/August for Watch7/Ultra
• Stable – August/September for Watch7, Watch6, and Watch5
• Uncertainty – Galaxy Watch4 series

The rollout begins in July 2025 with the Galaxy Watch8 series. These new smartwatches will launch with One UI 8 Watch pre-installed, giving users immediate access to the latest software features and improvements.

Around the Watch8 reveal in July, Samsung will start a Beta Program for the Galaxy Watch7 and Galaxy Watch Ultra. This phase lets select users test One UI 8 Watch early, providing feedback before the stable version releases.

Following the Beta Program, the Stable One UI 8 Watch update will directly reach the Galaxy Watch 6 and Galaxy Watch 5 series. This ensures that slightly older models still benefit from the new software enhancements.

The Galaxy Watch 4 and Watch 4 Classic’s eligibility is uncertain. Its official four-year software support promise, starting from its 2021 launch, ends in August 2025. If the rollout extends past August, it might miss this update.

Samsung’s One UI 8 Watch rollout starts with the Galaxy Watch8 series in July 2025, followed by Watch7, Ultra, Watch 6, and Watch 5. The Watch 4’s fate depends on timing, but all eligible devices will gain valuable upgrades.

Tizen to Wear OS plus One UI Watch

Samsung’s Wear OS journey began with the Galaxy Watch 4 in 2021, shifting from Tizen to a polished Google-Samsung collaboration. One UI 8 Watch could be the last update for some models, especially the Watch 4.

The next major Wear OS upgrade is set to replace Google Assistant with Gemini, offering better AI features. Samsung Health is also said to add an antioxidant index, while the UI could include the Now Bar for quick info access.
