**Samsung has expanded the One UI 9 beta** beyond the Galaxy S26 series, opening Android 17 testing to the Galaxy S25 family and last year's foldables. The wider rollout was confirmed on September 1 across India, South Korea, the US, and the UK, and it arrives as the company's newest flagships edge toward a stable release.

Eligible devices now include the Galaxy S25, Galaxy S25+, Galaxy S25 Ultra, Galaxy S25 FE, Galaxy Z Fold 7, and Galaxy Z Flip 7\. Galaxy S25 owners in India were the first to receive the initial beta build, a roughly 3.8GB download with firmware tag DZHK that carries Android 17 and the August 5, 2026 security patch. Registration for the One UI 9 beta runs through the Samsung Members app.

The S25 series joins the One UI 9 beta program that Samsung started on May 13 with the Galaxy S26, S26+, and S26 Ultra in Germany, the UK, the US, South Korea, India, and Poland. Those devices have since moved through eight beta builds. The latest, firmware ZZHM, is a 513MB update now live in South Korea with the same August security patch, and a stable One UI 9 build for the S26 series has already appeared on Samsung's servers. Together, the two signals point to a final release that is close at hand.

## One UI 9 beta: who gets it and when

For owners of the 2025 flagships, the practical effect is earlier access to Android 17\. Galaxy S25, Z Fold 7, and Z Flip 7 users who enroll through Samsung Members can install the beta now, while S24 and S23 generation devices, plus several Galaxy A models, remain in internal testing with no public schedule announced.

For Galaxy S26 owners already in the program, One UI 9 beta 7 has been rolling out globally, and the eighth build followed for South Korea. On the S25 side, the first beta is being received in the UK and South Korea as well as India, with enrollment banners for the US and UK appearing in the Samsung Members app. The S26 series has averaged a new build roughly every two weeks since May, a cadence that hints at how quickly the S25 betas may follow.

The stable version of One UI 9 has been out since July 22, when it debuted on the Galaxy Z Fold 8, Z Fold 8 Ultra, and Z Flip 8\. That release pattern puts the S26 series next in line, with the S25 family and the 2025 foldables expected to follow with stable updates this month. Samsung has not published exact dates for either rollout.

## Why this matters

The gap between Samsung's newest and previous-generation phones is shrinking: owners of last year's models now get beta access roughly three and a half months after the S26 series instead of waiting out the full stable cycle. For consumers, the near-final S26 beta and the stable build on Samsung's servers mean the official Android 17 update for the S26 is likely weeks away, and the S25 stable rollout this month is the next milestone to watch.
