My iPhone 4 used to take really good quality photos but over time the quality has gone down and the photos are now fuzzy. I admit I have dropped my phone a few times, no cracks though the glass over the back camera is lightly scratched. Will replacing the camera or the back cover fix the quality? Please see attachments for examples of photo quality. First photo is good quality taken a few months ago, the second photo is poor quality taken a week ago.
