Found a Way I had the same problem and I did everything Pengpeng said. Go to the Play Store and install the Cool Symbols app. It's the one with the S in the heart. It is much easier than going to the link they give you. I tried downloadi g that link, it wouldn't let me open it. So when I saw the cool symbols app I installed that and got the icons.
Amazing this one worked I noticed all the emojis showing up from other people then I decided to install just to see if I could post them too. Funny my Sprint s3 never showed color emoji, but the Verizon s3 showed before i even thought about them. (In color)
Samsung s3 With this app i can see the emojis and get to use them on things such as instagram and that but when you sends a text it says it might be corrupted and then dont show the emojis to an iphone user or anything like that! If it worked then i would give it a 5*
Samsung galaxy s2 Since downgrading my phone, I couldn't figure out why all of the symbols wouldn't show up. Even with your notice of changing my settings. However, I came across this accidentally. Glad I did! Now all of the symbols show up! Maybe you should link this with the cool symbols emoji so people with an older phone will know.
Works great but... Ive completely fell in love with this app now that I've learned a better way to use!! But I do dislike the fact that there as much variety!! Add more symbols &'d its definitely 5 star worthy
Well On an s3 you are already able to view most emojis anyway but this just adds a bit more. For the dumbasses thinking that this app will insert emojis into their keyboard they're wrong. It clearly says its a font.
