Hi everyone, I have a question I want to ask you guys. I recently purchased my iPhone 5 from my regional carrier last month. We'll yesterday before I went to work my dog knocked my phone off the table and crackd the outer glass in the upper right hand corner, not to bad, only have 3 spider cracks running down the screen. Everything works on it, Except the phone function now for some reason, not even through Bluetooth. I can't hear dial tones and no one can hear me and icant hear them, not even on speaker. But I can hear my voicemails and FaceTime and everything that requires a mic and the speaker fine. What could be causing this. Worked fine until the crack in the outer glass.
