iOS 26.4 beta 2 has been released for developer testing, following the initial beta launch just a week earlier. The build number for this update is 23E5218e, which enhances various features for iPhone users, including updates to the Games app and RCS encryption capabilities.
This beta version enables testing for end-to-end encryption in messages between iPhone and Android devices, marking a significant expansion from previous limitations that only allowed iPhone-to-iPhone communication. However, this feature will not be available to customers until future updates of iOS, iPadOS, macOS, and watchOS 26.
Additionally, a new toggle for "Reduce Highlighting Effects" has been introduced in the Accessibility menu, aimed at minimizing visual effects on buttons and sliders. Users will also notice UI changes in the App Store and Games app, with the Search bar now repositioned. Enhancements to the dark mode display in Control Center popups are also included.
