One UI 9 Testing Underway: Samsung Gears Up for the Galaxy S25 Launch

Samsung’s One UI 9 Testing Hits the Galaxy S25 Series

Samsung is keeping its foot on the gas when it comes to software development. While the tech world has been buzzing about the early One UI 9 beta programs for the Galaxy S26 and the surprising tests for the unannounced Galaxy S26 FE, the current flagship hasn’t been forgotten. Internal testing for the One UI 9 update has officially kicked off for the Galaxy S25 series.

We haven’t seen the specific build numbers just yet, but the timing suggests that S25 owners won’t have to wait much longer. If these internal tests go smoothly, we could see the first public One UI 9 beta—powered by Android 17—rolling out to the Galaxy S25 lineup in the very near future.

What’s Next for One UI 9?

While the S25 and S26 series are getting the beta treatment, they won’t be the first to run the finished software. Samsung has clarified that its next generation of folding devices will be the trailblazers, shipping with One UI 9 right out of the box.

Expectations are high for the upcoming Galaxy Z Flip8, Galaxy Z Fold8, and the much-talked-about Galaxy Z Fold8 Ultra. If the latest rumors hold weight, we’ll see these devices debut at a major Unpacked event in London, tentatively scheduled for July 22.

This aggressive testing schedule highlights Samsung’s commitment to faster deployment. For S25 users, it means the chance to play with Android 17’s newest features is just around the corner. We’ll be keeping a close eye on any leaked screenshots or feature lists as the internal testing continues.
