A feature that drops and returns on a phone or tablet is usually a background battery-optimization or connection-management setting killing it, not failing hardware. For iPhone FaceTime audio and video, first test FaceTime audio and video with another contact on Wi-Fi and cellular.
What this covers
- iPhone FaceTime audio and video with this exact failure state
- Diagnosis across Apple service/account activation versus camera, microphone and network

Try in this order
0 of 4 completedCapture the exact failure state
ReversibleNote how long the device was idle or locked before the drop, and whether it correlates with low signal or a Wi-Fi handoff. Expected behavior: activate the selected address and maintain media over the current network.
Isolate the component boundary
ReversibleTest FaceTime audio and video with another contact on Wi-Fi and cellular. Disable battery optimization for the one app and test with the device kept awake on a single network. Boundary to separate: Apple service/account activation versus camera, microphone and network.
Correct only the proven cause
ReversibleCorrect the selected reachable address, permissions or network path. Exempt the app from aggressive battery management, or turn off adaptive Wi-Fi/cellular switching for the test.
Verify and stop safely
ReversibleRun the same use pattern that triggered the drop for at least 30 minutes without it recurring. Do not share Apple Account passwords or verification codes.
