Flash Keyboard

Unlike other similar applications, Flash Keyboard is focused more on the visual side and less on the functionality, meaning that the main feature of the app is the emoji support. Of course, you would need a similar app to receive them.
The developers explained that the Flash Keyboard comes with skins, emoticons, emoji, and stickers. To make it even more interesting, users can even create their own stickers, if they want to.
Furthermore, Flash Keyboard has multi-language support, not to mention auto-corrections and word suggestions, which are really important for the keyboard. Also, users should keep an eye out for new themes and stickers as the developers are always releasing some new pack full of goodies.
