I have had this issue no matter what ROM i run. WHen in navigation in my car dock the phone runs very hot to the touch. My Temp goes from 20-22c up to 48-50c in no time. Makes me very leery to run Navigation with this phone. Does a stock non-rooted phone run hot? I have tried Sapphire (favorite so far by far), BB, Cyan, etc... They all run hot with navigation. Makes me want to go back stock as i fear i am hurting the phone. Anybody else running hot with Nav??
