Noah just got a new Samsung Galaxy Note 3 Android phone and the emoji's are "disgustingly ugly." Leo says that yes, Samsung's emoji's are ugly and the problem is that there is no standard or specification of how they are drawn. Noah can check out iEmoji.com to see how they look from platform to platform. There's also EmojiPedia.org. And everyone has their own look.
Can he replace them? Leo says he can, but he may have to root his phone to do it. Leo says to be careful about that because while apps promise this, they may have side effects that break something, and some may be malware.
Another way he can get different emojis is by using a third party text program like Textra, which would allow him to use iOS Emojis.
