I have a Droid Razr M. It was working fine then I go to unlock the phone and it won't unlock. What shows up instead of the unlock screen is a white line in the middle of the screen. When I hit the unlock button again the white line goes away. I know the phone is not dead or anything crazy because I have SMS and the light is blinking. I really do not want to spend the money to get it fixed, or to get a new one. Any suggestions?
