Galaxy S25 and Older Models Finally Have a One UI 9 Rollout Date

Samsung Thailand says the Galaxy S25 series, Galaxy Z Fold 7 and Galaxy Z Flip 7 will get Android 17-based One UI 9 on Sept. 28.

  • On September 16, Samsung began rolling out One UI 9 for the Galaxy S26, S26 Plus, and S26 Ultra, marking the start of the Android 17-based update cycle for its flagship series.
  • Samsung Thailand announced that the Galaxy S25 series, Galaxy Z Fold 7, and Galaxy Z Flip 7 will receive One UI 9 on September 28, providing the clearest official roadmap for older device timelines.
  • Regional schedules provided by Samsung Thailand may not represent a confirmed worldwide timeline, as Canada expects a September 21 rollout for the S26 while official messaging for older models remains limited.
  • Scheduled for an October release, the Galaxy S23 FE receives its final major OS update; Samsung originally promised 4 major updates when the phone launched with Android 13.
  • Older devices like the Galaxy S22 series will not receive One UI 9, having already reached their final major Android 16 update, though Samsung continues quarterly security patches for legacy models.
