I have the Nokia 1520 and when I point the camera at a person with them lined up in the middle of the screen they look fine but if I line their head up to the top of the screen their head (upper body) is distorted. It is like a fish bowl effect or something. It is like that for everything and does not have to be a person but a person is an easy test. The picture is distorted at the bottom of the picture too but not as bad. Flip the camera to the side and the picture is distorted at the sides. Take the picture and it is saved distorted. I can't upload pictures to show you right now.
Can someone with a Nokia 1520 test their camera and let me know if you have the same problem.
