My friend's N4 is refusing to charge. He says he plugs it in and the port gets really hot, and the phone is not charging at all. Also, his headphone port is tweaked. It will only put out audio to the right earpiece. I don't know if these problems are related, given the distance of the charging port from the headphone jack, but who knows anymore with these electrical gadgets. Anybody have any ideas? Hope it's not common cause I love my phone.
