Hey, all, I've had this S3 since Spring of 2013, dropped it dozens of times, so I wasn't too surprised when my friends started telling me that they couldn't hear anything, not a peep, from my end during calls. But, strangely, my friend was able to hear me perfectly well two days ago, when I accidentally called him without remembering that my mic was "broken." And I also noticed that my phone is perfectly capable of recording sound for a video. I can take a snapchat and the sound comes in clear and loud. I tried restarting it and turning "call noise reduction" off and on. Still haven't done a factory reset. Does anyone have any idea why my phone is only incapable of transmitting sound?
