Problems cutting people off I am a complete novice with these phones.  When I have a call I seem to cut people off with my cheek on the screen - how can I stop this?
If  you cannot keep distance between screen and your skin (cheek) as bigbadonk420 said. Then, in my experience, always speak from your phone with headset connected. There by not having the tension of cutting the call and giving freedom to the hands simultaneously.  Simple isn't it...
