Just purchased 2 new iPhone 6. Downloaded ZEDGE on both phones. On one phone it worked perfectly. On the other when it came to "Scan QR Code", one phone went right to the camera app, the other goes to a black screen with the words QR scanner at the top and at the bottom it says "Scan to link your iPhone to Tonesync". It will not let me access the camera app. I have spoken at length with my service provider, Consumer Cellular, where I purchased the phones, to no availability. They referred me to the Genius Bar at Apple and they could not help me either.
