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.

Bug fixes for a smoother experience

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.

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.

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.
Samsung is upgrading its Bespoke AI fridge models with new features. The company has announced the rollout of a new software update, which brings new features for its Bespoke AI Refrigerators with screens.
The update is being applied to Bespoke AI Refrigerators with AI Family Hub launching in 2025 first, with availability coming after the completion of the latest software update on AI Family Hub screens or SmartThings.
One of the company’s key executives said that Samsung aims to enhance the user experience through continuous software upgrades for existing products, taking us one step closer to a true AI Home experience.
The new software update from Samsung offers the Voice ID feature provided by Bixby to Bespoke AI fridge models. It’s a multi-voice recognition function, which identifies users’ voices registered either on the refrigerator or a Galaxy device.
Using this feature, users can check:
- Registered schedules on the calendar
- Photos using simple voice commands
- Trigger an alarm on their phone to check its location
Owners of compatible models can also look forward to more upgrades this month. Samsung plans to gradually apply this update to the Bespoke AI refrigerators with AI Home. For refrigerators with AI Home, the update expands the service area for Samsung TV Plus.
- Expansion next to Canada, Brazil, Australia, Mexico, and India.
New way to activate Bixby on the screen
The update debuts a new method to trigger the Bixby assistant. An additional option has been added to activate Bixby by double-tapping the display. Users can make the most of this feature by selecting their preferred method in the settings.
