12 Quickly React to Incoming Texts
If you’re used to using social media, you might like having the option to “like” or “react” to the things you see. Like with many other tricks on this list, iOS 11 brings a similar feature to Messages. It’s called “tap back.”
Instead of texting a reply back, you can send a “reaction” — ranging from “haha” to a like or dislike.
Just tap and hold on a message bubble until the reactions popup appears. Tap your option, and the recipient will see your reaction instantly.
