What Samsung Has Confirmed (Preceding the Leak)

Samsung officially said the Galaxy S25 series will start receiving One UI 8 in September 2025, following its debut on the Z Fold 7 and Flip 7 series.

Beta builds have been rolling out since May, with Beta 5 hitting recent S25 units—focusing on bug fixes for moon-zoom glitches, hotspot errors, and more. This hints the stable launch is right around the corner.

And earlier coverage hyped One UI 8 as a leap forward with smoother animations, deep Galaxy AI hooks, dynamic wallpapers, boosted multitasking, and upgraded Quick Share tools.

Take it with that smidge of salt—but it’s spicy enough to track:

  1. Fresher Flagship Love First
    The S25 series is the VIP—getting the update mid-September. Total flex on Samsung’s rep.
  2. Rollout in Ripples, Not Waves
    Next up: S24 fam and A-series hype. Then tablets and wearables. Samsung’s spreading the upgrade love thoughtfully to avoid meltdown-mode.
  3. OTGs and Oldies Get Love—Eventually

  4. Smartwatch Season Not Skipped
    Gearheads, your watches are up next in early October. That Galaxy Watch 7 benefiting from those One UI 8 Watch betas? You’ll feel the love—eventually

Pro Tips before the update arrives

  • Back your device up before diving in—this is a major OS jump.
  • Stay chill and watch the Samsung Members app for your region—it’s your rollout radar.
