Hi all, I just got my new iPhone 4S yesterday, and while playing around with the camera, I discovered a little semi-transparent grayish-black circle on my all my pictures and on the Camera app itself. Here's a picture of it while the Camera app is on: (the circle is in the bottom right corner, a little bit above the capture button) Now, the strange thing is, the circle disappears when I switch to video recording mode. Here's a pic: Could this actually be a software problem instead of a camera lens issue? Anyone has this problem too? Would love to bring it down to a Genius bar but there are no Genius bars where I live (Singapore). It is only visible on lighter/white areas of the picture, but it would make me happier to not have to worry about the speck in my photos.
