These characters are also available as Memoji Stickers in iOS 13, which show up in the frequently used section of the emoji picker on the default virtual keyboard. If you don't use them enough to find their appearance useful in the emoji keyboard, there's now a way that you can get rid of them.
As of iOS 13.3, Apple has added an option to prevent Memoji Stickers from showing up in your Frequently Used emojis on iPhone and iPad. Make sure you're running iOS 13.3, then follow the steps below to turn them off.
- Launch the Settings app on your iOS device.
- Tap General.
- Tap Keyboard.
- Swipe down to the bottom of the screen.
- Toggle off the switch next to Memoji Stickers.
