Apple's latest iOS 27 beta quietly closes one of the more glaring gaps in its RCS rollout: you can now reply to a specific message in a cross-platform chat with an Android user.
The second beta of iOS 27 adds long-press reply threading to RCS conversations — the same mechanic iMessage users have had for years. The update also fixes how tapback reactions render on images and videos; iOS 26 replaced emoji with text strings like "[x loved an image]", which was both ugly and confusing. Both sender and recipient need RCS-capable phones and carriers for threading to work. Apple shipped RCS support in iOS 18 and added end-to-end encryption for iPhone-to-Android RCS in iOS 26.5.
This matters because RCS was supposed to be the great leveler between iPhone and Android messaging — a baseline that made green-bubble chats feel less like a downgrade. Every missing feature, from encryption to threading, has let Apple off the hook with users who care about cross-platform parity. Closing these gaps one beta at a time makes the "it's not as good as iMessage" argument harder to sustain.
Apple is still catching up to what Android users have had in Google Messages for some time — but at least it's moving in the right direction, even if beta-by-beta incrementalism is a slow way to get there.
