In a significant move to enhance user security, Apple is breaking down the walls between smartphone ecosystems. The latest iOS 26.4 beta 2, released to developers, introduces long-awaited end-to-end encryption for RCS messages between iPhone and Android devices, marking a new era for encrypted iOS Android messaging.

How Encrypted iOS Android Messaging Works in iOS 26.4

This update expands on the initial beta, which limited the encryption feature to Apple’s own ecosystem. With the new version, this powerful security shield now extends directly to the Android operating system. This development bridges a major security gap that has existed for years in cross-platform communication.

Furthermore, for the system to work during this test phase, Android users who wish to participate must have the latest beta version of the Google Messages application installed on their devices. This ensures compatibility and allows for a seamless, secure connection between the two platforms.

Seamless Activation for Enhanced Security

Once the update is installed, users can find the end-to-end encryption option within the RCS Messaging section of their settings. Apple has enabled this protective layer by default, providing continuous security without requiring any user intervention. The company is thoroughly testing this feature with beta users before rolling it out to the general public in a future stable release.

New Lock Icon Confirms Secure Communication

To provide clear visual confirmation of the enhanced security, the messaging interface has been updated. When an encrypted chat begins, a special lock icon will appear on the message screen for both iPhone and Android users. This is a familiar symbol for many, as the same icon has been used to indicate end-to-end encryption in traditional iMessage chats since 2011.
