The last photos/videos I took are not being shown in Photos
I have a 5th Generation iPod touch (Model MD723BT/A) running the latest update (iOS 8.4.1). I took some photos and videos however when accessing Camera Roll they cannot be seen. When opening the camera application, the videos/photos I took can be seen in the lower left so I'm guessing they are stored somewhere, however when I tap on it, it goes to the latest picture before the ones I took. In settings->general->about there are 4,523 photos however on camera roll the number is 4,587.
Please be aware that the photos/videos I took are needed for legal reasons so it is extremely important to try and get them back.
