[AC Question]

My Nexus 4 was plugged into my cigarette lighter charger and when I picked it up it was too hot to handle and the screen went blank. When I plugged the charger back in the red light went on an the screen stayed black. After it cooled down it worked fine. Does this mean I have a defective charger>

Could be. Or a short somewhere in the phone. Replacing the charger is cheaper than the labor cost of determining whether the one you have is bad. (Most "dollar store" chargers work fine. I've been using 2, one in each car, for a few years. Only 1 Amp on mine, but I just want to keep the battery from discharging when I'm using the GPS, so that's okay. [The phone can draw 1.2 Amps if I modify a 2 Amp charger.])
