When either someone calls me or I call someone, I can hear them clearly but they can’t hear me. This is a brand new phone, what can be wrong?

If the microphones on your iPhone aren't working - Apple Support

I’ve got same microphone problems and it’s still happening on my second 16 pro as apple replaced the first one
