One UI 8.5 Update May Have Broken Video Calls for AT&T Users

One UI 8.5 is actively rolling out, and more Galaxy devices are joining the party. However, there seems to be an issue with video calls, reportedly for those on AT&T network, running One UI 8.5. Multiple users say the feature isn’t working as expected.

Many Galaxy phones face video call issues after One UI 8.5 update

According to multiple user reports (via Piunikaweb), video calls placed through the default phone app fail to connect. Even when calling another Android phone, including Galaxy devices from Samsung, the call triggers a “Video declined” message. The same happens when the call is initiated from the other device.

Users note that the issue began right after installing the update. Before One UI 8.5, video calling worked without any problems. Reports span several models, including Galaxy S23, S24, and S25 series devices, along with some Galaxy A lineup phones, although not everyone seems to be affected.

There’s also confusion around who’s responsible. Some users claim AT&T support says it’s an issue on Samsung’s side. Meanwhile, Samsung support reportedly points to the carrier. That leaves affected users without a clear answer, as neither side has officially acknowledged a fix yet.

Interestingly, third party apps like Google Meet continue to work fine, suggesting the issue is limited to the native dialer based video calling feature. Some users say calls connect normally, but enabling video immediately results in the same error message.

We’re monitoring the situation, and once there’s an update from either party, whether AT&T or Samsung, we’ll update this article. Given the growing number of complaints, it’s likely a fix will arrive in a future update, and hopefully sooner rather than later.
