So while calling with my iPhone 2g the call sounds like it does when you get a text message near a speaker and that buzzing sound comes. also the person on the other end can barely hear me. however when i mute the microphone the sound goes away. also in speakerphone mode the phone seems to works fine. I dont think its a direct hardware issue with the microphone because when i go to voice memos it is able to record and playback audio just fine. its just during calls. Anybody got an ideas on how to fix this?
