I swapped out my Droid for the one VZW sent because the original one would drop my calls and screen black out. The replacement Droid works but one minor problem, every time I make a call the screen goes black and never lights up even when I press the power button. The only way the screen lights up is if I slide out to open the physical keys. Very annoying if I wanted to punch in numbers for voicemail, etc. This didn't happen in the original Droid. Can this be fixed? Or would I need to call VZW yet again.
