Testing on the iOS 26.4 update is continuing, and Apple released the second beta today. The main new feature is an expansion of RCS encryption testing, but there are a few other small tweaks.
End-to-End Encryption RCS Testing
With the second beta of iOS 26.4, Apple is testing end-to-end encryption for text messages sent between iPhones and Android devices.
End-to-end encrypted messages can now be sent to an Android user, and if encryption is enabled, there will be a lock icon on the message. Encrypted conversations are not available for all devices or carriers during the texting period. iOS users will need to have iOS 26.4, and Android users need the latest version of Google Messages.
Apple does not plan to implement end-to-end RCS encryption in iOS 26.4, but it will come later this year.
