Overview

  • Samsung’s Galaxy Z Fold7, Z Flip7 and Watch8 lineup went on sale in 49 markets on July 25 following record-breaking preorders that saw foldable demand outpace last year’s models.
  • Both foldables ship with Android 16-based One UI 8 out of the box, marking the first time Samsung has debuted a major One UI version on its Z series instead of the Galaxy S lineup.
  • Under a new software cadence, major One UI updates will now align with Google’s Android releases on foldables, while Galaxy S phones will receive interim “.5” updates rather than full OS version bumps.
  • The stable One UI 8 release for the Galaxy S25 has been postponed as Samsung rolls out a fourth beta build, leaving S25 owners without a firm date for the final update.
  • Samsung sealed a loophole in its internal test servers to curb early One UI leaks even as users decry lost FlexWindow features on the Z Flip7 and slowdowns in legacy flagship software support.
