I've never had a problem charging before. All of a sudden today in the car when I plugged it into the charger I always use, which is a Samsung usb plug, a message came up about original chargers and there was a red x in the battery it would not charge. When I got home my phone is nearly dead and now it won't connect to my s5 charger that the phone came with. It's not even registering that it's plugged in. Has anyone else had this issue? What can I do??
