With iOS 26.5, Apple continues testing an important feature in the messaging area: end-to-end encryption (E2EE) for RCS messages between iPhone and Android devices. This addresses an area that has previously represented a clear security vulnerability compared to iMessage.
Apple had already begun testing E2EE for RCS in the iOS 26.4 beta. However, it was communicated early on that the feature would not be part of the final version. Consequently, it was removed before release.
With iOS 26.5, the feature has reappeared in the beta. This shows that Apple is actively continuing development, even though the rollout is not yet complete.
E2EE reintegrated in iOS 26.5
End-to-end encryption for RCS is back in the current beta of iOS 26.5. A toggle switch has reappeared in the "Messages" section of the Settings app within the RCS options.
As in the previous test phase, the feature is enabled by default. This suggests that Apple is testing background usage without requiring manual activation.
Difference between RCS and iMessage
Currently, there are significant differences in encryption:
- RCS messages between Android devices are already end-to-end encrypted.
- RCS messages between iPhone and Android are currently not encrypted.
- iMessages between iPhones have always been end-to-end encrypted.
With iOS 26.5, Apple is working to close the gap in encryption for cross-platform RCS messages.
The importance of end-to-end encryption
End-to-end encryption ensures that messages can only be read by the devices involved. Neither providers nor third parties can access or intercept the content.
Once the feature is activated, encrypted conversations in the messaging app will be marked with a lock icon. This makes it immediately clear whether a conversation is protected.
Limitations of the beta version
The E2EE feature in iOS 26.5 is still in the testing phase. This entails some limitations:
- This feature is not available on all devices.
- Support depends on the respective mobile network provider.
- A final launch has not yet been confirmed.
These points show that Apple is initially testing the feature under controlled conditions before rolling it out widely.
iOS 26.5 shows progress in RCS encryption
With iOS 26.5, Apple continues the development of a secure, cross-platform messaging solution. The reintegration of the E2EE feature demonstrates that this topic remains a priority.
Even though the feature isn't officially available yet, the ongoing testing phase suggests that encrypted RCS messages between iPhone and Android are planned for the long term.
