Everything else works except for calls.
Repeating back voicemail works for both top speaker and speaker phone. All music, games, recording, etc works.
However when someone calls me I cannot hear them and they cannot hear me even if I put on speakerphone.
When I call someone, I can't hear the ringing either.
I've tried software restores on both itunes and the iphone settings but so far the issue has not gone away.
2 recent events might have caused the issue.
1. I have kept the iphone in a lifebox until a couple days ago where I removed the lifebox, it has stayed in the lifebox for briefly over 1 year, I've also been using headphone jack alot recently when I go to gym. I am unsure though if it stopped working slightly before or after I removed it from the lifebox.
2. I've recently just updated the phone to the latest IOS 7 version before it stopped working though not sure if I made a successful call or not after update (now my phone is IOS 8 but issue still persists)
Does anyone know what might be causing this issue?
