I went to settings/general/keyboard, and it's there. I deleted it, added it back. Still can't use emojis. I rebooted phone, still can't use. I upgraded to ios 10.02, still can't use. When I press down hard on the little globe on the keyboard, it comes up as an option, but when I press the emoji option, the globe disappears for a split second and then automatically reverts back to my standard qwerty keyboard. Two days ago I could use emojis, but now for some reason, I can't. Anyone else got this problem?
