My phone had cracked but was usable-nothing coming out-or I thought.  I did not have a front cover but did have my back covered.  I began to have issues with the left side of my body, the side I place the phone on.  Has  anyone else had issues with their body regarding the phone.  I have gone to a doctor, urgent and emergency care-nothing.  The only thing that solved the issue was after process of elimination and talking to people, not putting the phone on my ear, or having it as an alarm clock, close to my bed.
