Overview
- Samsung has started releasing stable One UI 8.5 to Galaxy S25 devices in its home market, with SamMobile confirming availability for the S25, S25 Plus, S25 Ultra, and the S25 FE.
- For Galaxy S25 FE users in South Korea, beta testers face a download of about 368MB while non‑beta phones can see packages over 4GB, reflecting the jump to the Android 16–based build.
- The May security update includes critical patches for CVE-2026-0073 and CVE-2026-0051 that Google warns could allow remote compromise without any user action, so Samsung advises updating as soon as possible.
- One UI 8.5 centers on protection features such as Theft Protection, Failed Authentication Lock, and Identity Check, and it adds Galaxy AI upgrades like a Perplexity-powered Bixby, Photo Assist tools, and Quick Share that works with Apple’s AirDrop.
- Samsung has not provided a global timetable for the rollout, and support staff have pointed users to watch the Samsung Members app’s Notices for the official roadmap, while separate leaks suggest a staggered expansion later this week.
