iOS 26.4 beta 2: What’s new?
RCS encryption
Last week’s iOS 26.4 release added support for testing RCS encryption, but only for iPhone-to-iPhone communications. With iOS 26.4 beta 2, Apple expanded testing to include messaging between iPhone and Android devices.
Apple says:
In this beta version, RCS end-to-end encryption will be available for testing between Apple and Android devices. This feature does not ship in this release and will be available to customers in future releases of iOS, iPadOS, macOS, and watchOS 26. End-to-end encryption is in beta and not available for all devices or carriers. Conversations marked as encrypted are end-to-end encrypted, so messages cannot be read when they are sent between devices.
