I've been experimenting with the Note 3 ' animated photo feature and so far, it's been rather interesting trying it out on Zest and Honey. While I haven't got it fully figured out yet, the function basically takes 2 or more animated subjects and allows you to freeze one.
It does come with a few flaws though, firstly, your subjects ideally shouldn't be touching each other as it makes freezing one difficult. The other is, once u have edited a photo, it becomes a fully animated gif and it can't be edited or changed back to the original file anymore.
