Microphone not working on iPhone 7. (Phone Calling and Siri)

im seeing a lot more of this issue on the iphone 7 and 7 plus im starting to think its a signature issue with them I restored one and started working fine for 5 minutes and the same thing happened. It has some issue with the audio if you have warranty take it to apple and get it swapped out if not contact ipad rehab or sts telecom.

Apple disgust me. For a company to treat is customers like this, they really don't deserve any in the first place.

I’m also facing this problem, microphone stop working after update 12.1.2.

It’s been a month of this crap for me. I’ve literally tried EVERYTHING every forum says to do and NOTHING. I haven’t been able to resolve this issue at all. I’m beginning to think Apple does this on purpose to get people to just buy another phone. Literally nothing worked to fix this.
