- Eligible users enroll in the Samsung Members app and then install the update from Settings under Software update, with spots limited by region.
- New features include deeper Quick Panel layout controls, a Tape tool and new pens in Samsung Notes, DeX windowing tweaks, Game Booster shortcuts, and accessibility upgrades like Text Spotlight, unified TalkBack, and adjustable mouse‑key speed.
- Security tightens with One UI 9 flagging and blocking high‑risk or sideloaded apps and adding clearer controls to manage unknown app installs.
- The rollout is phased across countries, with the US and South Korea joining early and India and Poland slated to start May 26, and Samsung is updating first‑party apps such as Expert RAW to ensure Android 17 compatibility.
