I just got the white front and back for my iPhone 4. I did the job all like it sead on the web and everything was working perfect exept for the front camera. It used to work fine befor all the time. Now it freezes when I try using it on camera app and FaceTime won't show anything at all. I can see people but they don't see me. I have checked if it was loos but it was not. Please help me out. Or if anyone knows where I can get a replacement front camera. Thank you all that help.
