In the event you are having connection issues with charging or you are having difficulty charging. I ran into this issue and Apple said the port needed to be replaced for 75.00 through Sprint. Before I forked out this amount, I decided to youtube my issue to see if I can fix it myself. In one of the comments for the video it said to take a pin or paper clip and clean out the lint. Well I pulled out so much lint I could have made a small sock for my dog.
