In iOS 7, when I used the camera from the lock screen (4S), it would only show an album of the pics that I took in that 'session'. But now on iOS 8 the lock screen camera app gives access to my entire photo library!? No need to unlock the phone? How can I block this? I don't want people just picking up my phone and start browsing my pictures!! I looked in all the privacy and camera settings, but can't find how to block this.
