One UI 8 Beta Begins for Galaxy Phones: Full List of Eligible Devices Revealed

One UI 8 Testing Has Started: Full List of Samsung Galaxy Phones Eligible for the Android 16 Update

I still remember the buzz in our newsroom the first time Samsung introduced One UI back in 2018.

I had just wrapped up my hands-on review of the Galaxy S9 when our test unit unexpectedly received the One UI beta overnight.

It was clunky at the time, but something about the minimalist redesign felt like a genuine reset. Seven years later, I was sitting with a Galaxy S25 Ultra in hand, when a new notification blinked: “One UI 8 Beta available.”

This article serves one clear purpose - to give you a verified, up-to-date, and complete list of Samsung Galaxy phones and tablets currently undergoing testing for the One UI 8 update, along with exclusive insight into what users can expect from Android 16-based software. If you’re wondering whether your device made the cut, this breakdown has you covered.

One UI 8 Based on Android 16: What’s Changing

Samsung’s latest skin is more about refinement than reinvention. Based on Android 16, One UI 8 builds quietly on its predecessor, bringing smarter user flows, privacy enhancements, and device-to-device consistency. Here are some of the standout features:

Now Bar and Now Brief: These context-aware suggestions are better integrated with your calendar, location, and habits - useful if you're juggling apps while commuting or working remotely.


Multimodal Input: Use voice, visuals, and touch in one fluid input stream. Think of searching for a photo by describing it, then editing it via voice.


Adaptive Layouts: Especially useful for tablets and foldables, the UI morphs based on device size and orientation. Side-by-side multitasking has never felt more natural.


Privacy and On-Device AI: Samsung now allows users to choose between on-device AI processing and cloud integration, with Samsung Knox Vault keeping sensitive data isolated.


Easier Sharing and Service: Quick Share now supports QR-based file transfers. Service registration for repairs is also smoother with NFC tagging.

These aren't headline-grabbing features, but they reflect Samsung’s growing confidence in its ecosystem - and its AI strategy.

🛈 Note: Eligibility does not guarantee immediate rollout. Final updates may arrive in staggered phases, depending on region and carrier.

Regional Testing & Carrier Influence

Samsung’s internal testing process spans Korea, Germany, India, and select parts of the US. 

Public beta builds often appear first in South Korea, followed by Germany and India - the three most active developer regions for Galaxy devices.

In India, early reports suggest that users with the S24 Ultra and Galaxy A55 have received the internal testing builds via Samsung Members. 

However, carrier-locked variants (especially in the US) may lag behind by 2–3 weeks post global rollout.

Early Hands-On With One UI 8 Beta (S25 Ultra)

Testing the beta on my S25 Ultra felt familiar but sharper. Animations have been tuned slightly to feel snappier, especially when opening the camera or switching modes.

Samsung’s new contextual keyboard suggestions showed up when I booked a flight - it suggested flight check-in, weather at the destination, and hotel details from my Gmail.

Quick Share via QR worked flawlessly transferring a 2GB video from my phone to my Galaxy Book. 

What surprised me most was how seamlessly the UI adjusted when flipping the phone from portrait to landscape - widgets realigned with zero stutter.

There were some bugs, especially in split-screen mode where certain apps crashed. 

But this is beta software, and based on Samsung’s history, these rough edges will likely be polished in the coming weeks.

Comparison with One UI 7

Performance: One UI 8 feels more responsive across animations, particularly on devices with 120Hz displays.


AI Integration: Smarter and more accessible. Unlike One UI 7 where AI features felt experimental, One UI 8 uses them for real-time contextual productivity.


Multitasking: Improved UI handling in split-screen and pop-up views, especially on foldables.


Battery Optimization: Early testing suggests a 5–8% battery improvement on devices running Exynos chips.

What Users Should Expect Next

Samsung’s typical rollout pattern begins with its latest flagships, so expect the Galaxy S25 and Z Fold 7 series to receive the stable build first.

Public betas for other high-end models like the S24 Ultra and Tab S10 Ultra are likely within weeks.

A-series and M-series models generally see updates 6–8 weeks later. Samsung prioritizes markets like India and Korea for mid-range rollouts due to higher user base and feedback volume.

Samsung has also promised longer support windows - the Galaxy A17 5G recently launched with six years of software support, hinting that similar longevity will apply to current flagships.

Final Thoughts

The One UI 8 rollout reflects Samsung’s slow but deliberate evolution. It doesn’t try to reinvent Android - instead, it enhances it with smarter suggestions, better device context, and improved consistency across form factors.

While it's too early to recommend updating to the beta unless you're an enthusiast, this update feels more cohesive and human-centric than any previous version.

The full rollout may stretch into Q4 2025, but if you see One UI 8 testing on your device - take it as a sign. Samsung is investing more than ever in optimizing the Galaxy experience across its sprawling ecosystem.
