An update on Galaxy S22 One UI 8.5 release, plus bad news for Galaxy A53 & A33 owners - tech-ish.com

One UI 8.5 is built on Android 16 QPR2, not the original Android 16 base, marking a fundamental shift from prior updates. This new Android branch introduces updated APIs and developer tools, making the update significantly heavier and less compatible with older devices. Samsung tested One UI 8.5 firmware for the Galaxy S22 in late 2025 but halted development by early April 2026. The update now appears unlikely for the Galaxy A53 and A33 due to hardware limitations and increased software demands. This change signals a move away from consistent mid-cycle updates for older devices.
