I have the app Photos on my iPad mini, on iOS 7.
I am viewing a stream shared by a friend.
When I am on a photo, I can save it to my Camera Roll.
But, when I am on a video, I cannot save it to my Camera Roll. The feature is missing.
1) How can I save a video to my Camera Roll ?
I want preferably a solution that do not need a computer.
2) Bonus question : Why has Apple limited this feature to photos ?
