Samsung's One UI 8.5 beta program shows no signs of slowing down as the tech giant continues to roll out fresh updates across multiple devices. This latest push indicates that the company is actively ironing out the final wrinkles ahead of a widespread public release. The most recent beneficiaries of this testing phase are the Galaxy A55, A36, and A35.

Specifically, One UI 8.5 Beta 2 is now available to beta testers using these three mid-range smartphones. The new firmware versions—ZZDC, ZZD7, and ZZD9, respectively—mark the second beta milestone for the popular A-series lineup.

Unsurprisingly, this update prioritizes bug squashing and system optimization over flashy new features. According to the release notes, Samsung has addressed various glitches affecting the camera, Bluetooth connectivity, the Quick Panel, and the navigation bar, alongside other UI elements. The overarching goal is to deliver a rock-solid user experience before the stable version drops.

Originally debuting with the flagship Galaxy S26 series, One UI 8.5 introduced a more refined, modern aesthetic, coupled with significant enhancements to performance, camera capabilities, and AI-driven tools. However, fine-tuning these advanced features for mid-range hardware understandably requires a bit more time in the oven to ensure stability.

Recent reports suggest that the stable version of One UI 8.5 could hit the Galaxy S25 as early as April 30, starting in South Korea before a broader global rollout. For mid-range users with the A55, A36, and A35, the wait might extend until June, though Samsung's roadmap is always subject to last-minute adjustments.
