Overview

• Samsung expanded stable Android 16 releases to more devices and regions: Galaxy S23 now in the US, Galaxy S22 in India and Europe, Tab S10+ and S10 Ultra in India, the UK and the US, Z Flip 5/Z Fold 5 on US carriers, and Z Flip 4/Z Fold 4 across parts of Africa, Asia and Europe.
• Midrange models joined the wave, with Galaxy A25 gaining One UI 8 in Europe and India’s Galaxy F36 and M36 receiving the update earlier than expected.
• US Galaxy S23 units received distinct firmware for unlocked (S91xU1UEU6EYI5) and carrier-locked (S91xUSQU6EYI7) models, while S22 builds varied by region, reflecting Samsung’s typical staggered, device‑specific packaging.
• For the Galaxy S22 series, One UI 8 on Android 16 fulfills the promised fourth and final major OS upgrade, with outlets noting security updates will continue though eligibility for One UI 8.5 remains uncertain.
• Feature additions span a revamped DeX based on Android 16’s desktop mode, stronger Secure Folder protections, redesigned Quick Share, updated Samsung Internet, My Files and Weather apps, and new Modes & Routines actions; rollouts show differing download sizes and monthly security patches by market.
• Leaks indicate One UI 8.5 is built on Android 16 QPR2, with reports pointing to system and UI enhancements that Samsung is expected to debut alongside the Galaxy S26, though exact features and device eligibility may vary.
