Microphones work, but not during phone calls.
My mind is absolutely boggled.
I'll try to make this short.
I have an iPhone 6 Plus. Both microphones seem to work perfectly fine
(I've tested the bottom microphone with Voice Recorder-- super clear.
I've tested the top microphone with Siri and Voice Dictation, understands me every single time)
Whenever I make a phone call with this phone, the person on the other end cannot hear me whatsoever. This is not a matter of being muffled, this is literally no sound at all. The only sound that comes through sometimes is a crackling noise, almost like ruffling a bag of chips or something.
How can both of the microphones work perfectly fine but then completely not work only during phone calls? Anybody know what is going on?
