IPhone 5 microphone STILL not working after replacing?

Alright my iPhone 5 microphone stopped working when I was out of town at work. When I received phone calls the caller couldn't hear me until I put the call on speakerphone. Siri wouldn't work nor voice memos. So it has to be the mic if it was a hardware issue.

When I got home I did 2 full restores. Cleared every little lint and dirt from the areas where the three mics are located and that did nothing. I ordered a new part from ebay and replaced it and it does the same thing. I really can't think of what else it could be.

One thing that confused me was that if I flicked or blew into the mic when I was recording a voice memo a sound would be recorded also if I yelled really loud It would record my voice but very softly. So is the sound just being muffled?

I read about the noise cancellation feature the iPhone 5 has, could something about this feature be messing up the sounds it receives?

Added (1). There's no mute button on siri and in voice memos… Smh

Added (2). To Mang: I updated to the newest iOS 7.0.3 a couple of days before I noticed the problem. It MIGHT be THAT update that messed my phone up but I have no way of telling if it really is that. Wouldn't everyone have that problem after the update?

Did you upgraded your software to iOS 7?
Because if you did, maybe its the problem because iOS 7 is full of bugs. I've seen and heard so many people that they are so much disappointed about there iOS 7 and they like to downgrade it to iOS 6 but they can't because of the new version of iTunes.

  • My iPhone microphone is not working A week ago my iPhone 4 microphone stoped to work. It just stoped, did not lose it in the ground or something, just stoped to work. When I call someone or if someone call me, they can't here me, but I can here them. But If I turn on speaker, they hear me normally. Do you have any thoughts on how I can fix this?
