hello my iphone 7 microphone greyed out can you please replace it

Hello Rlucas0606,

It sounds like the speaker button or audio source selection button is dimmed during calls. We’d like to help however we can.

To confirm, are you able to record a voice memo in the Voice Memos app without issue?

Make a recording in Voice Memos on iPhone

If you are unable to record a voice memo, then the next thing we would recommend is to have your iPhone inspected for service.
