Send Messages With Cool Effects
One of the coolest things you can do when sending messages is use the built-in effects on your iPhone 8 or iPhone 8 Plus.
When you are in the messages, you can type your message and then 3D Touch in on the send arrow to bring up the options to send messages with effects. You can pick an effect that just changes the bubble, or you can go with a full screen effect by tapping on the upper options.
I like sending the bubble effects in normal conversations as they are cool, but not overwhelming. The full screen effects are really cool for birthday's or for big messages.
