Early 2027 is the expected release window for Samsung’s Android 17-based One UI 9.5, with the stable version likely debuting alongside the Galaxy S27 series.
One UI 9.5 is tipped to deliver bigger UI and UX changes than One UI 9.0, including more transparent interface elements, better large-screen layouts and deeper Galaxy AI and Gemini integration across Samsung apps.
Q4 2026 is when Samsung could open a beta program for select high-end devices, potentially issuing five or six test builds before the public launch.
Q1 2027 is also when older eligible Galaxy phones and tablets may start getting the update, with the wider rollout possibly finishing in Q2 2027.
Up to 6 years of upgrades for recent mid-range devices and up to 7 major Android updates for most recent flagships will shape which Galaxy models qualify.
