In the latest iOS 26.4 developer beta, Apple has quietly enabled early support for end-to-end encrypted RCS chats. On paper, that sounds like a big deal. RCS has long been one of the most debated topics in the iPhone vs Android messaging saga. But if you were hoping this means secure iPhone-to-Android texting is here, not quite.
For years, Apple avoided adopting Rich Communication Services, better known as RCS, arguing that the standard lacked proper end-to-end encryption. In the meantime, iPhone users had iMessage (fully encrypted, blue bubbles), while conversations with Android users dropped down to plain SMS. That divide became part technical limitation, part ecosystem strategy.
Apple finally introduced RCS support with iOS 18, but encryption wasn’t included. Now, in iOS 26.4 beta, there’s a new toggle in Settings that enables encrypted RCS for supported users. Encrypted chats show a lock icon, similar to iMessage, indicating messages are secured in transit.
Here’s the limitation
Right now, encrypted RCS only works between Apple devices. The feature does not yet enable encrypted messaging between iPhones and Android phones. In other words, the green-bubble security issue remains unresolved.
There’s another interesting detail: encrypted RCS activates only when iMessage is turned off. If iMessage is enabled, Apple’s own messaging system continues to take priority for Apple-to-Apple chats.
Google has offered encrypted RCS in its Messages app for compatible devices for years. But true cross-platform encryption requires every major player, including Apple, to fully implement the same specification.
So when will Android-to-iPhone encryption arrive?
That’s the big question. This beta confirms Apple is actively working on encrypted RCS. But full cross-platform support doesn’t appear ready yet. It’s also absent from the stable iOS 26.4 release roadmap. Realistically, widespread encrypted RCS between iPhone and Android users could still be far away.
For now, this update is progress, just not the breakthrough we have been waiting for. Apple is moving forward on RCS encryption, but it’s doing so carefully and, at least for now, still within its own ecosystem boundaries.
