Overview
- Samsung accelerated the stable One UI 8.5 rollout on Monday and Tuesday, issuing device‑specific builds for phones such as the Galaxy M36 in South Korea (M366KKSU5CZE3) and the Galaxy M35 in India (M356BXXU8DZE3).
- One UI 8.5 is built on Android 16 QPR2 and typically bundles the May 2026 security patch; OTA packages are large, commonly around 3 GB to 4 GB depending on model and region.
- The update brings visible UI refinements like a floating bar in first‑party apps, more custom Quick Settings, and cross‑platform file sharing support that works with Apple AirDrop for iPhones, iPads and Macs.
- Rollouts remain phased and region dependent, with South Korea commonly receiving builds first and other markets following within days to about a week if no major issues appear, and firmware codes differ by market.
- Users can check for the update in Settings > Software update > Download and install, and should install over Wi‑Fi with sufficient battery; Samsung started One UI 8.5 on its S26 flagships and is testing One UI 9 in parallel, so further expansion is expected over the coming days and weeks.
