Fix: Phone app cannot use microphone
A phone app usually cannot use the microphone because microphone permission was denied, privacy settings changed, the app is stuck, or another audio device is connected.
Quick answer
Open phone privacy settings, allow microphone access for the app, then close and reopen the app.
