Does anyone have an idea as to why my FIFTH Droid4 has stopped charging? I originally thought it was the screen protector which made the phone "think" it was always on. I originally had the Koi wallpaper but on my 3rd phone I did not load any extra apps other than my Good email utility. I've erased all data and started from scratch and still, no charging. Thank goodness this is a company phone otherwise I would have pulled out what little hair I have left. Thanks for any help.
