I have a 4S and have just downloaded iOS 7. Whenever I view a photo from the gallery it opens up central on screen, then when I swipe left or right to the next photo it comes up central then 'snaps' to right-aligned on the screen. So if I have a subject central to the photo, it's now shifted to the left of the iPhone screen. Is anyone else having this problem? Is there anyway to fix it? Edit: seems to happen after swiping left or right twice.
