Testing of the iOS 26.4 update continues, and Apple released the second beta version today. The main new feature is the expansion of RCS encryption testing, but there are a few other small improvements.
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.


Messages with end-to-end encryption can now be sent to Android users, and if encryption is enabled, the message will have a lock icon. Encrypted chats are not available for all devices or carriers during messaging periods. iOS users will need 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.

In the Account Center options for the App Store and Apple Music, the “Apple Account” text is now left-aligned and has the same rainbow logo as the Apple Account in the Settings app.
