Apple's upcoming iOS 26.5 will encrypt RCS messages between iPhone and Android users. The update closes a long-standing security gap in cross-platform messaging.

iOS 26.5 introduces end-to-end encryption for Rich Communication Services (RCS) messages sent between Apple and Android devices. Previously, RCS messages lacked this protection, leaving them vulnerable to interception. RCS has been a key protocol for Apple's Android interoperability, especially following pressure to improve iMessage compatibility. The encryption addition strengthens privacy across platforms without requiring users to download third-party apps. Apple has gradually expanded RCS support since 2024. This encryption layer marks a significant step toward parity with iMessage's security standards. The feature works automatically—users need not configure settings to enable protection. The rollout timeline for iOS 26.5 remains unconfirmed, though Apple typically releases major updates in fall cycles. This move aligns with ongoing industry efforts to standardize secure messaging across device ecosystems.
