I've noticed that when I use a standard mini-USB charger, like the one provided with the RAZR MAXX, the phone is very glitchy, screen problems, Swype problems, when I use it while it is plugged in. As soon as I unplug the charger, the problems go away. It doesn't seem to be damaging the phone at all, and it charges just fine on the generic charger, but is there a difference between the original charger sent with the RAZR MAXX (which I can no longer find) and any garden-variety mini-USB charger?
