Default Anyone having emoji issues!?

So i got the G3 the day it came out for Sprint, and everything was working fine. I was sending emoji to everyone with no issues. I started messing with some files, and i thought i broke the emoji somehow because all of a sudden, when i text someone, they couldnt see any emoji. They could see them on social networks but not text. I just chalked it up as a loss

However my phone got stuck in a bootloop so i had sprint replace it for me, so naturally i thought my emoji issues would be over since it is a brand new phone. But its the same! Nobody can get my emojis when i text. Even when i use emoji that are baked in texting apps such as Hangouts. Does anyone have this problem, and whats the solution?
