I have literally had zero of these problems. This cameras reviews have claimed it is the first camera to be as good or better than the 5s. Remember all megapixels means is how big you can blow up the picture before it starts distorting and zooming I believe. An 8MP camera can be better than a 16MP, 20MP, 40MP in actually picture quality depending on the screen size. One thing about the iPhone phone is remember, it has good resolution on the 5s and is smaller than the S5. I think to many people expect to much out of a phone camera. I have read that different people have had different results using other camera software/programs.
