Samsung widened its One UI 9 beta testing this week, with new builds appearing within hours of each other for the Galaxy S26, Galaxy S25, Galaxy S24, Galaxy S25 FE and Galaxy Watch 8 Classic. Tarun Vats spotted the activity across five different device families, a sign that the software is moving through more of Samsung’s lineup at the same time.
That matters now because One UI 9 is already landing on devices while Samsung keeps pushing the next test version forward, and the pace of those builds is what many Galaxy users are watching most closely. The Galaxy S26 series looks nearest to a stable release, with Beta 6 likely next after the fifth beta arrived last week, while the Galaxy S25 series public beta looks genuinely imminent after an internal build cleared Google Play Protect certification and a new ZZHC build turned up on Samsung’s servers this week.
One UI 9 first launched with the Galaxy Z Fold 8 series on July 22, but the rollout picture is broader than that single release. The update brings Now Nudge, My FanCam, improved Bixby and AI privacy tools, along with a redesigned Quick Panel and voice input for Photo Assist. It also includes AI Assistant Activity logs that show which apps an AI has accessed and when, while AI Privacy Alerts are meant to flag apps asking for more location or background access than they should need.
The line Samsung is drawing is also clear: some devices are moving toward public beta, while others are being held back from the newer Gemini Intelligence features. The Galaxy S24 series and Galaxy S25 FE are still progressing toward their own public beta programs, but the company appears to be separating broader One UI 9 testing from the more advanced AI layer it does not want on every device.
That split is what gives this week’s build wave its importance. One UI 9.5 is already in development, with My Custom Widget and a larger visual change expected later on the Galaxy S27 next year, which means Samsung is effectively running two tracks at once: finishing One UI 9.0 while shaping the next version behind it. For Galaxy owners, the next checkpoint is the Galaxy S25 public beta, and the new server build suggests that wait may be close to ending.
