 RCS is kind of an upgrade to the old text message system where now you get typing indicators and read receipts and things like that just between green messages. What would be green on your iPhone? And so now for the first time, you'll be able to text people on Android and they'll see when you're typing or when you've read it if their phone and their carrier supports RCS. So that's something that people are already seeing in the wild like, oh, you switched to Android? No, my iPhone has RCS now. So that's kind of an insider set of letters, but once you see it in the wild, you kind of get used to it.
