Hi all, I bought a used iPhone 5 off of Craigslist last Friday. It powered up, activated at Verizon store just fine, made a call, etc. However, on Sunday when I needed to talk to someone, the mic wouldn't work. I could hear the other person, but they could not hear me. The speakerphone, Facetime, and Siri all responded correctly, but my voice could not be heard by the other person. I checked the Voice Memos app and it didn't pick anything up when recording and a decibel app stayed relatively steady at about 30db. So, I did a complete restore on the phone Monday night and set it up as a new phone. The microphone worked then when recording a voice memo that night. The next morning I was making a voice call on my way to work and the microphone worked for about two minutes and then quit. I had to use the speakerphone again. I did two restores last night on the phone and neither one of them got the microphone back working. I can still use Siri, Facetime, and the speakerphone, but the regular microphone is out. Is this possibly a software issue since it worked after one restore? I have read that for some phones iOS 7 killed the microphone and I am hoping that this is the case with mine and that 7.1 will correct this, but who knows. I took it to a local repair shop and the owner told me that it may be software as he saw it with AT&T phones, but not Verizon and to try the restore again (which I did last night). He said to replace the ribbon, it would be $100. I really don't want to have to go that route, but if I have to, I will. Anyone else have this problem? Have I exhausted all of my options and just need to suck it up and pay for the ribbon repair?
