One UI 9 Testing Expands Across 49 Galaxy Devices

One UI 9 testing now covers 49 Galaxy phones and tablets, and Samsung is already validating models beyond the expected Galaxy S26 beta track. The internal builds include Galaxy S25, Z Fold 7, Tab S11, and several Galaxy A series devices, pointing to a broader Android 17 rollout plan.

Samsung One UI 9 beta still starts with Galaxy S26, but S25 may follow

The public Samsung One UI 9 beta remains limited to the Galaxy S26 series for now, even as internal testing spreads to older flagships and recent foldables. That split matters because it shows Samsung is keeping the first public wave narrow while preparing more devices behind the scenes.

One UI 9 testing devices now span 49 Galaxy phones and tablets, which is a wider pool than many users may have expected at this stage. The Galaxy S25 is part of that internal testing list, along with the Galaxy Z Fold 7 and the Galaxy Tab S11 lineup. In practical terms, that suggests Samsung is not only working on the next beta release, but also checking how the software behaves across different hardware types.

If Samsung opens the program to the Galaxy S25 next, it would point to a faster handoff from internal builds to early users in the premium Android tier. That would not automatically mean a stable release is close, but it would show the update moving beyond a single launch family.

Galaxy A series update list and Tab S11 testing point to broad rollout prep

The internal testing list is not limited to premium phones. Midrange models such as the Galaxy A57, A36, and A15 5G are already included, alongside the Galaxy Tab S11 lineup and older Tab S9 devices. That mix suggests Samsung is staging One UI 9 across both phones and tablets rather than focusing only on its newest flagship lineup.

Samsung firmware test server activity also points in the same direction. While internal testing does not guarantee immediate public access, it usually signals that the company is working through device-specific checks before a wider release. In this case, the spread across recent foldables, tablets, and midrange phones shows a broad rollout prep pattern that is easy to miss if you only look at the beta headline.

For Galaxy users, the most important detail is not just that One UI 9 is being tested. It is that Samsung is testing it across a wide range of models, which often decides who gets Android 17 first in the Galaxy ecosystem. Devices already on the internal list are usually the ones most likely to move through the update pipeline sooner, though timing can still vary by region and model.

At this point, the clearest read is simple: Samsung One UI 9 testing is no longer centered on one flagship phone. It now stretches across 49 Galaxy models, with S25, Z Fold 7, Tab S11, and several Galaxy A series devices all in the mix. That does not confirm a public release schedule, but it does show the company is preparing a wider Android 17 Samsung rollout than the first beta window suggests.
