My old photos in my iPhone4 camera roll have become blurred and I can't take new photos, as they aren't saved properly (either they look blurred or i see a blank or black rectangle in the camera roll). Any ideas? I do not want to reinstall the iOS please...
Yes I've tried it, several times. I've shut down all the apps, then put in "airplane" mode, then reset, then reset again..
Nothing changes
