Apple’s iOS 26.4 Beta 2 Introduces Enhanced RCS Encryption and User Interface Refinements
Apple has released the second beta of iOS 26.4, bringing significant updates aimed at enhancing user security and refining the interface. A notable advancement in this beta is the expansion of end-to-end encryption (E2EE) for Rich Communication Services (RCS) messages, now encompassing communications between iPhone and Android devices.
End-to-End Encryption for RCS Messages
In the initial beta of iOS 26.4, Apple began testing E2EE for RCS messages, but this was limited to iPhone-to-iPhone communications with iMessage disabled. The second beta extends this feature, allowing iPhone users to send encrypted messages to Android users. To utilize this functionality, iPhone users must install the second beta of iOS 26.4, while Android users need the latest version of Google Messages. Encrypted conversations are indicated by a lock icon on the message. It’s important to note that during the beta testing phase, E2EE may not be available for all devices or carriers. Apple has stated that while E2EE is being tested in this beta, it will not be included in the final release of iOS 26.4 but is planned for a future update later this year.
