Full Emojis? topic

I got the galaxy camera 2 for christmas and i noticed that while it does have some emojis it doesnt have them in color or many of the, im using google keyboard btw and i went to the emoji wiki page where you can see all the emojis and it showed some, the rest were squares and on google keyboard it shows ones i would never use unless i use swipe like so ☺ but i dont know what to type for every one, and lets be honest that just takes to much time i tried installing hi font and tried a notocoloremoji, apple emoji font and another one , but only the noto one showed on my font list and even then the emojis didnt show so am i doing something wrong or what, am i using the wrong app? Font? What? And sorry i didnt sew the camera 2 forum and i figured in some way this is considered devolpment and also didnt see a q&a
