iOS 26.4 beta 2: Everything new, how to try it now

iOS 26.4 beta 2 has launched for developers, and early adopters can test several new features and changes. Apple has added encryption for RCS messaging between iPhone and Android devices, a notable step for security-minded users. Apple wrote in its release notes: "In this beta, RCS end-to-end encryption will become available for testing between Apple and Android devices.

This feature is not shipping in this release and will be available to customers in future iOS, iPadOS, macOS, and watchOS 26 releases. End-to-end encryption is in beta and is not available for all devices or carriers. Conversations labeled as encrypted are encrypted end-to-end, so messages can’t be read while they’re sent between devices." The beta also adds a setting to reduce the highlighting effect on the edges of buttons and sliders as an accessibility option.

The Home Screen edit menu — where you can add a widget, customize your wallpaper, and perform other tasks — now uses more transparent Liquid Glass.
