This was so easy to do, I hope it hasn't been posted yet cause I couldn't find it. If you don't have all the cool emoticons available for your text boxes this is how it's done .
- Go to settings
- Scroll down to General
- Go to Keyboard
- Scroll down to Keyboards again
- Add New Keyboard...
- Go to "Emoji" and add it
You should now have all of them :bookworm: Enjoy!
