Hi
I can tell you how to solve the reversed image. With the camera running look on the side of phone where the up/down volume keys are. If you press up button you will notice image on screen change. I think the down button inverts the image? Up or down this should correct your inverted image problem.
With regards to people experiencing lines and blacked out screens this appears to be a phone fault.
