Samsung's One UI 8.5 stable update has reached the Galaxy M55s, bringing firmware version M558BXXU3DZE3 to devices. India leads the initial rollout, following last week's Galaxy M55 update. The upgrade delivers Samsung's latest Android skin improvements to mid-range hardware.

The update wave extends beyond the M55s to include the Galaxy F16, F17, F55, and F56. Each model carries distinct firmware identifiers: E166PXXU5DZE2 for the F16, E176BXXU5CZE9 for the F17, E556BXXU5DZE3 for the F55, and E566BXXU5CZE2 for the F56. All five devices currently receive the update in India, with broader regional availability expected shortly.

This staggered release strategy shows Samsung prioritizing its mid-range portfolio for software updates. Users who haven't received the update yet can manually check through Settings > Software update. The firmware versions suggest Samsung is methodically testing builds across different hardware configurations before wider deployment.

The update brings Samsung's latest interface refinements to budget-conscious consumers, ensuring these models stay current with recent feature additions and security patches that typically debut on premium devices first.
