You can better express yourself in the messages you send by formatting, styling, or animating the text in your message, the message bubble, or the entire screen.
Note: To send and receive messages with text formatting or text effects, you and your recipients must be using above the keyboard, then select your preferred style (bold, italic, underline, or strikethrough) or animated effects (big, small, shake, nod, explode, ripple, bloom, or jitter).
The Messages app may suggest effects to apply as you type.
Tap , then tap the gray dots to preview different bubble effects.
You can send messages with full-screen effects—such as lively lasers, a moving spotlight, or echoing bubbles—that play when your recipient gets your message.
