I've had my RAZR M for two days now, everything is awesome except... At work I'm able to have my phone plugged in to the charger when the batt starts getting low. Today when I plugged it in and tried to send a text message, the touch screen was rendered useless. It was hitting all over the place, usually nowhere near where I touched, also couldn't use other apps and games because the touchscreen wasn't working right. I unplugged it from the charger and it worked flawlessly. What would cause the touchscreen to go haywire when the phone is plugged in to the charger???
