I haven't really been using my iPhone 5's camera until recently, because I wanted to check it out for an upcoming trip to Europe. I've noticed there is a smudge or something in the pictures I have been testing the camera out with. I rotated the picture to see if it was the screen protector I have on it, or if it was the camera itself, and indeed, it was the camera. I purchased the iPhone in January and am wondering if Apple will replace my phone or not because of this issue. I've checked the camera and cleaned it to see if it would get rid of it, however it did not. Below is a picture where you can see the smudge on the top center of the bottom of my MacBook Pro.
