i purchased a used sony z3 which has some brighter spots on a few places on the screen,has anyone any idea what these are caused by? it doesnt affect the use of the screen at all. Also the front facign camera doesn't work,it simply shows as a black screen,the icons for the camera are all present but no image through the view finder. The rear camera does work although i'm not sure the pictures are as sharp and crisp as they should be. Any ideas what the problems are guys and any fixes i coul try please
