A phone or tablet feature that has completely stopped should be checked for a disabled permission or setting before assuming hardware failure. 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
What it does not cover
Try in this order
0 of 4 completedCapture the exact failure state
ReversibleCheck whether the feature is grayed out, missing from settings entirely, or present but unresponsive when used. 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. Test the same feature in a different app that uses it, and with recently installed apps disabled or in Safe Mode. 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. Re-enable the permission or setting, or update/reinstall the one app where it fails.
Verify and stop safely
ReversibleConfirm the feature works from a cold restart in at least two different apps. Do not share Apple Account passwords or verification codes.
