I have a Samsung Galaxy S4 Active that will not charge. It wouldn't charge from the wall, so I connected it to my home computer, and this stopped after about 3 days. Afterwards, I used a stripped USB to charge my phone, but this stopped working as well. It will not charge whatsoever, I've cleaned out the phone, tried repairing the port, used my battery in someone else's phone and vice versa, with no results. Is there anything anyone can do to assist me?
