Re: emoji on galaxy note 2 version 4.1.2
OK, so you can add emojis natively ONLY in the stock keyboard, wich we DON'T have in our Note 2's...we have Samsung's keyboard, which does not support emojis.
But the system does! What gives!?
Don't panic, just find an add-on. (Not the simplest method, not elegant perhaps, but so far the only way). I use MultiLing keyboard (Free from Google Play, no adds). It's not perfect, mind you, but it does let you add emojis to your messages. A few caveats, though:
1) You're using a separate keybaord. That means you have to select it every time you want to insert an emoji and switch back to your keyboard of choice when you want to insert text (unless you like how MultiLing handles text and make it your default keyboard, which I personally don't).
2) Emojis are visible ONLY to systems that support it. Twitter supports it on mobile (Android 4+, iOS 5+), Facebook doesn't natively support it, Whatsapp natively supports it (they even have the emoji keyboard built in), etc.
3) Bear in mind that not all systems can display emojis, so don't expect all your friends to see what you see.
4) PCs cannot show emojis natively, they need a plug in to show them on-screen. Newer Macs, however, can.
