Samsung Widely Rolls Out 4GB One UI 9 Update to Galaxy S26 as S25 Gains Early Access

3 articles · Updated · 9to5Google · Sep 29

Summary

  • Galaxy S26 phones are now receiving Samsung’s stable Android 17-based One UI 9 update across more regions, with availability expanding from the US and South Korea into Europe, India and Canada.
  • The wider push follows a delay after Samsung said older devices would start getting the software earlier this month; the stable version first debuted on the Galaxy Z Fold 8 and Flip 8 in July.
  • Roughly 4GB in size, the update is also starting to reach other Galaxy models in staggered waves, including the S25 series, Z TriFold, Z Fold 7, Z Flip 7 and Z Flip 7 FE.
  • Those non-S26 rollouts remain limited in some cases to beta participants for now, but Samsung’s broader release pattern suggests more devices should be added over the coming days.
