Last night my stupid friend grabbed my bb, and i guess the camera button was pressed. Now everytime i go to camera, there is this black screen with two silver lines on each side for like a milli second and then it goes to my camera and it works perfectly. it always just used to go to my camera without that weird black and silver thing. but now everytime i open and close the camera it does that for like a milli second. it that normal? because it never used to do that and i got the phone 2 weeks ago and now im freaking out.
