Install iOS 12.1.1 for New Emojis
If you skipped iOS 12.1, the iOS 12.1.1 update brings new emoji characters to your iPhone, iPad, iPod touch.
iOS 12.1 delivered more than 70 new emoji characters including mango, lettuce, a cupcake, a moon cake, red hair, gray hair, curly hair emoji characters, and a whole lot more.
If you want to give the new emoji characters a whirl right now you'll need to be running iOS 12.1 or the iOS 12.1.1 update.
Unfortunately the only way for someone else to see these emojis is if they're also running iOS 12.1 or iOS 12.1.1 on their device.
iOS 12.0.1, iOS 12.0, and iOS 11 users will see a jumbled mess of emojis and icons like a square or a square with a question mark in the center.
