Hi, greate to see that you have the same issue with me. I use my iPhone to capture an image. When I set the home button on the right (from my view), it can scan pretty good. But if I set my iPhone in other direction, it returns very bad result. Could you please give me any suggestion. I try through a lot of solution to detect detection of image, but it's useless. Thanks a lot
