Apple has released the second beta of iOS 26.4, introducing a suite of new features and refinements aimed at enhancing user experience across various applications. This update brings significant advancements in messaging security, music personalization, accessibility, and user interface design.
End-to-End Encryption for RCS Messaging
A notable addition in iOS 26.4 Beta 2 is the expansion of end-to-end encryption testing for Rich Communication Services (RCS) messages between iPhone and Android devices. This development aims to bolster the security of cross-platform communications, ensuring that messages remain private and protected from unauthorized access. Apple has indicated that while this feature is currently in the testing phase, it will be made available to the public in future releases of iOS, iPadOS, macOS, and watchOS. Users can identify encrypted conversations by a lock icon displayed on the message thread. ([9to5mac.com](https://9to5mac.com/2026/02/23/ios-26-4-beta-2-heres-whats-new/?utm_source=openai))

This feature leverages Apple’s AI capabilities to curate music selections, offering a dynamic and personalized listening experience.
