One UI 8 Watch Beta will soon be available for the Samsung Galaxy Watch 6 and Watch 5 series. Samsung is yet to drop the update, but preparations are underway in full swing. The company may soon reveal its expansion plans covering older watch models.

Samsung is getting ready to release One UI 8 Watch Beta for the Galaxy Watch 5 series, as the first Beta build has been spotted on the server with PDA version number R905NKOU1ZYG2 – as first spotted by X user ya_sking12767.

The identification number suggests it’s a Beta firmware, which could be provided to Watch users. Currently, the One UI 8 Watch Beta is available on the Galaxy Watch 7 and Galaxy Watch Ultra models in the US and South Korea.

Debuted with the Galaxy Watch 8 series, the new One UI 8 Watch software is built on Wear OS 6. It brings enhanced health features and some exclusive additions to the latest smartwatch models, such as an antioxidant index.

In addition, the new One UI 8 Watch comes with features like Bedtime Guidance to optimize sleep, Vascular Load to measure stress on the vascular system during sleep, and Running Coach to support personalized training strategies.

Samsung Members is the gateway to join the One UI 8 Watch Beta Program. The process is pretty simple if you are running One UI 8 Beta on your Galaxy S25 device; if not, you will have to give consent to the terms and conditions before joining.

The latest mobile devices boot the newest software iterations. Samsung said the One UI 8 will roll out with the Z Fold 7 and Flip 7 and expand to old eligible devices gradually, while no specific timeline was shared for the Watch update either.

Samsung has started testing the One UI 8 update on 2022 foldable smartphones – Galaxy Z Flip 4 and Galaxy Z Fold 4. It shows that the company is regularly working to make this major update available for older devices.

A reliable tipster spotted the first One UI 8 testing builds for the Galaxy Z Flip 4 and Galaxy Z Fold 4 smartphones. These builds are F936BXXUAIG3 and F721BXXUAIG3, indicating that major update development has begun.

It is worth mentioning that testing is currently underway on the Indian variant of these foldable smartphones, as the CSC code is INS. This indicates that Samsung will soon make the major update available for these smartphones once the One UI 8 rollout begins for older devices.

Along with these foldables, several Galaxy devices, including mid-range, low-budget, and premium ones, are also under internal testing for One UI 8. Some of these devices are Galaxy A56, Galaxy A36, Galaxy S24 series, Galaxy S23 series, Galaxy Z Flip 6, Galaxy Z Fold 6, and more.

Samsung launched the stable One UI 8 update with the Galaxy Z Fold 7, the Galaxy Z Flip 7, and the Galaxy Z Flip 7 FE. However, Samsung is also testing new features on the Galaxy S25 series with a Beta update.

Even after the stable update release, Samsung hasn’t reveal the OneUI 8 rollut plan for older devices. It is expected that the company will soon make this major update available for more Galaxy devices. Stay tuned for more information.

Apple’s product ecosystem always gets praise, even from rivals, for its design harmony. Whether it’s iPhones, iPads, or MacBooks, or software like iOS, iPadOS, or macOS, all feature the same curves and design language. Samsung’s design is officially going that way, starting with the One UI 7 and Galaxy S25 series, followed by One UI 8 and Galaxy Z7 series, and highly anticipated in the One UI 8.5 and Galaxy S26 series next year.

Galaxy x One UI – Design Philosophy

Samsung is focusing on harmonizing its flagship products with the One UI design. Both hardware and software will bring similar curves and design language. It’s going to evolve with each iteration of new flagships and One UI versions for sure.

One UI 7 is the start

Samsung MX Division’s Yang confirmed that the company has aligned the product’s corner radius with One UI icon geometry. The design shift was also seen in the Quick and Notification Panel’s components, aligning with the S25 series aesthetic.

One UI 8 leads the way

Samsung’s new foldable phones retain the One UI 7 design language. It focuses on uplifting the user experience by enhancing system apps and services. As far as the UI design is concerned, the curves and aesthetics are optimized in foldables and One UI 8.

One UI 8.5 will follow

With One UI 7 initiated design harmony and One UI 8 leading the way, Samsung is committed to continuing it further. Samsung’s Yang confirmed that Samsung will “continue to align the GUI (Graphic User Interface) with the underlying style of the product for future releases, too.”

While this statement has no mention of One UI 8.5 and the Galaxy S26 series, the strategic design deployment is indeed planned for these two products. Some credible sources confirmed that the next flagship lineup will debut with One UI 8.5 software.

Galaxy S26 series is almost six months away, and we are not aware of the design changes. Samsung’s approach may continue to focus on refining the design rather than making a major appearance overhaul, so expect a S25 Ultra-like design.

Expect new features and smoother animations in Samsung’s next One UI 8 iteration. Galaxy AI may also see a huge boost in terms of usability and productivity. Multimodal and anticipation abilities would also be worth noticing in the future Galaxies.

One UI 7.0 is the most dramatic OS update Samsung has ever installed in its devices. The software has new features, UI upgrades, and smooth animations that make it better than any other Android skin.

The past three quarters have brought numerous challenges for Samsung, including One UI 7.0 (Android 15) and 8 (Android 16) development, Galaxy S25 series release. Don’t forget, it’s also a big year for Galaxy AI features, which may have extended the firmware development for specific devices.

As of July 2025, this OS upgrade covered Galaxy S-series, Fold-series, Flip-series, A-series, F-series, M-series smartphones alongside Galaxy Tab-series tablets with this Android 15-based software. The rollout is now officially active for more than three months, and we’ve officially entered in One UI 8 era.

Conclusion

Except for a few exceptions, Samsung has installed the One UI 7.0 rollout for all eligible models. Soon, Samsung will release One UI 8 for the Galaxy S25 series and other models, starting a chain for another OS rollout. If you want to know more about One UI 8 and stay updated with the latest news, check our dedicated section here.

On July 9, Samsung held its Unpacked event, where it unveiled new foldable phones and smartwatches. Samsung also introduced Android 16-based One UI 8 but didn’t reveal the Stable Update release date for Galaxy devices. Recently, plenty of rumors backed by Support Chat screenshots spread online, claiming release dates that are untrue.

Galaxy Z Fold 7, Z Flip 7, and the Z Flip7 FE come preinstalled with Android 16. Samsung is running the One UI 8 Beta Program to optimize the update for the Galaxy S25 series; the sooner the testing completes, the sooner the Stable release date will approach. For now, there is NO OFFICIAL RELEASE DATE FOR ONE UI 8 UPDATE.

While Samsung didn’t reveal a release date, it did mention in its press release that the new OS upgrade “is expected to commence with the Galaxy Z Flip7 and Fold 7.” This statement is about One UI 8’s market debut with new foldables around July 25.

Regarding existing devices, Samsung officially announced that the update “is expected to gradually rollout to other Galaxy devices.” That said, the update’s coming gradually to older phones but there’s no release date specified by Samsung.

Statements from Samsung’s support staff can’t always be considered official statements. The support staff’s main purpose is to assist consumers with their purchases, product information, feedback, queries, and concerns, not the software part.

If you come across such stuff that the One UI 8 update drops mid-July, take it as a rumor material. The Beta testing is still underway, and Samsung is making improvements across the OS to ensure a bug-free software is shipped to the consumers.

One UI 8 amplifies the features and user experience introduced in One UI 7. Minor tweaks across the user interface, redesigned stock apps, enhanced connected ecosystem UX, and expanded Galaxy AI features make it worth the wait.
