Samsung has begun rolling out its One UI 8.5 Beta 5 update to Galaxy S25 users in the U.S., just days before its Galaxy Unpacked event on February 25, 2026. The patch focuses on a Bixby version update, hinting at deeper AI integration rumored for months.

While the changelog is sparse—labeled as One UI 8.5 vZZAN—the update weighs ~548MB, suggesting minimal changes beyond the Bixby overhaul. Early access is limited to beta testers in the U.S., with broader availability expected by week’s end.
