Would somebody kindly be able to explain to me why I am seeing a huge difference under Usage for Photos & Camera between my iPads? On my iPad Mini with Retina I have absolutely no photos or videos whatsoever yet under Usage it shows 308Mb. On my iPad 3rd Gen I have 6 photos and no videos and under Usage it shows 195Mb used. Why the big difference? Both iPads are 16Gb running IOS 8.1.2. Thanks.
