AT&T users on Galaxy S23, S24, S25 and some Galaxy A models report that Samsung’s One UI 8.5 update breaks video calls placed through the native Phone app.
Users trying to call other Android devices see a “video declined” error, and the same failure can occur when another device starts a video call to the Galaxy phone.
Google Meet and other third-party apps still work, suggesting the problem is limited to the built-in Phone app rather than video calling across the device.
The issue appears isolated rather than universal—some phones in the same household work normally—and no similar reports have surfaced from other carriers or unlocked devices.
It remains unclear whether the fault lies with AT&T or Samsung as the stable One UI 8.5 rollout expands across eligible Galaxy devices.
