Samsung rolled out the One UI 8.5 stable update to three mid‑range devices: the Galaxy M55, Galaxy A16 5G, and Galaxy A17 5G. The M55 receives firmware M556BXXU5DZE3 with a 3 GB download, while the A16 5G gets version A166PXXU7DZE2 at roughly 2.3 GB. Both updates carry the May 2026 Android security patch and are being rolled out in India and Indonesia.

The Galaxy A17 5G receives firmware A176BXXU5CZE9, a 2.4 GB package, and also includes the May 2026 security patch. Samsung is distributing this build across India, Nepal, France, Bulgaria, and Vietnam, expanding the update’s geographic reach beyond its typical Asian focus. Users gain modest performance tweaks and refreshed security baselines without major UI changes for everyday smartphone tasks and minor battery.

By delivering One UI 8.5 to these budget-friendly models, Samsung reinforces its strategy of extending software longevity across the mid‑range lineup. Consumers receive the latest Android patch without needing to upgrade hardware, which could improve resale value and reduce fragmentation in emerging markets. The rollout demonstrates Samsung’s commitment to uniform security updates across diverse regions throughout the calendar year globally.
