In iPhones when you lay down your phone screen down the mic is physically cut off. That's why you can't call "Hey Siri" with a phone laying like that.

  Wrong. That's a software switch, not physical hardware.

  That just proves Siri is disabled, not the microphone.

  If the hardware switch is controlled by software then it isn't much of a hardware switch.
