Enhanced Privacy: iOS 26.4 Beta Introduces End-to-End Encrypted RCS Messaging Testing

Apple has recently introduced RCS support for iPhone users with the release of iOS 18.1. This update allows for enhanced cross-platform messaging capabilities between iPhone and Android users, including features such as typing indicators, read receipts, and the ability to send high-resolution photos and videos.

In a further development, Apple has announced plans to implement end-to-end encryption for RCS messages. The latest iOS 26.4 beta 1 release, which is currently being rolled out, offers an early opportunity to test this feature on iPhone devices.

It is important to note that the end-to-end encrypted RCS messaging feature is still in its initial testing phase and will not be officially launched with the iOS 26.4 update. Apple has stated that full support for end-to-end encryption in RCS messaging will be available in a future iOS 26 software update.

The new iOS 26.4 update introduces a toggle in the Settings app that enables users to test the end-to-end encrypted RCS messaging feature. This toggle is enabled by default, but access to the feature will be gradually expanded to more users during the testing period. It is essential to understand that the presence of the toggle in Settings does not guarantee immediate access to the encrypted messaging feature.

During the initial testing phase, RCS encryption will be limited to iPhone-to-iPhone messaging only. This means that communication between iPhone users with iMessage disabled will be encrypted. It is not currently possible to test the feature for messaging between iPhones and Android devices, but Apple has reassured that cross-platform testing will be available in the future.

Apple has also made changes to the Messages app interface to accommodate the introduction of RCS encryption. Users will now see a lock icon in chat threads when messaging with encryption enabled. This lock icon will also appear in iMessage threads, which have supported end-to-end encryption since 2011.

Overall, the addition of RCS encryption testing on iPhone devices marks a significant step towards providing full support for end-to-end encrypted messaging for all iPhone users. Apple’s developer release notes for iOS 26.4 emphasize that the feature is still in beta and will be gradually rolled out to customers in future software updates for iOS, iPadOS, macOS, and watchOS.

iOS 26.4 is currently available to developer beta testers, with a public beta release expected at a later date. For those interested in exploring the new features of the update, Apple encourages sharing feedback in the comments section.

In addition to the new features, Apple has also introduced a Google preferred source badge for 9to5Mac, allowing users to add the website as a preferred source on Google. The company includes a disclaimer about using affiliate links to generate income, along with a native banner advertisement promoting iPhone 17 accessories.
