The 1.2GB update (firmware ending ZA3) hits key pain points. Lock screen clock alignment gets perfected, widget search buttons become visible, and Gallery’s Live Effects run buttery smooth without stutters. Now Briefing and Phone app Favorites stabilize for daily reliability.
Battery life sees major gains – background app drain fixed for true all-day use. This polish previews February’s Galaxy S26 software while keeping S25 Ultra, Plus, and base models current.
US and Poland users get it soon. S25 owners: Settings > Software Update now.
