im trying to hand down my droid x to my wife. i did a master reset on it and everytime we try to do the activation call the screen goes black. the phone is working because it makes the call (you can hear it) but there is no screen. remove battery and try again...same result. master reset the phone again...same result. figured out that it will go black only during the phone call. i made the activation call. the screen went black. as soon as the call disconnected the screen popped back on. of course the phone was not activated in this call beacuse you need the screen to follow the prompts. any input?
