Another option you have (in case your device is running lower version of Android OS 4.4.2) is to install an add-on application for you to use emoji on your device. Either ways is fine.
For you to see different groups of emoji, tap on the small icons at the very bottom of the screen. Doing so will prompt you with a plethora of emoji characters to select from. Simply scroll up and down to view more options and tap on the small buttons located at the bottom to see additional groups of symbols, figures and characters available.
Once you're done, switch to the regular keyboard by tapping on the ABC button found on the bottom left corner.
