iOS 8.4 Update
My iPhone 6 worked just fine before 8.4. Now, when someone calls me, that isn't from an iPhone, I answer the phone and it will only hold the connection for 2 seconds and then immediately hangs up the call. Is this a known issue with 8.4 and iPhone 6? Or, is there something I can do to fix it?
