I have an LG G3 phone with kitkat (4.4.2), about 2 years old. When using the twitter app, there are some emoji I can't see (those belonging to Unicode 9). My LG keyboard only supports, AFAIK, Unicode 7 emoji. I have also tried installing Gboard but the emoji set is exactly the same one.
Although I have managed to survive so far without typing the newer emoji, I seriously can't forfeit seeing them on Twitter app (or any other place). Don't mind which version will be displayed (google, iOS, twitter or whatever) as long as they will be displayed (bonus points for a solution that will also include updating my emoji keyboard).
I am NOT interested in upgrading my OS, rooting or installing any other version - I'm completely fine with what I've got, just want to see those new food emoticons.
