If you've noticed that the emojis on your Samsung Galaxy S4 Android KitKat phone are different from iOS and the basic Google versions, it's because they are not from Google. Those are emojis created by Samsung which they plan on including in future mobile devices and the next firmware updates. The recent firmware released by Samsung included a special emoji set that looked a lot different from iOS and Google. They're still cute but it would be nice if we could use the original emotions and the Google emojis that we see on Hangouts. Even LG has its own version.
