iOS 27 Beta 1 Removes RCS End-to-End Encryption Temporarily

WireByte Staff · June 9, 2026

Apple's latest iOS 27 beta 1 has removed the end-to-end encryption feature for RCS messages between iPhones and Android devices. The company states this is a temporary omission during the beta development cycle and not a permanent change. The feature was recently added in iOS 26.5, improving cross-platform messaging security.

Key points

  • Apple's iOS 27 developer beta 1 temporarily lacks end-to-end encryption for RCS messages.
  • The feature, introduced in iOS 26.5, secures cross-platform 'green bubble' chats.
  • Apple indicates the removal is a normal part of the beta development branching process.
  • Users concerned about encrypted RCS should remain on iOS 26.5 until the feature returns in a later beta.
  • RCS encryption requires support from both users' and their contacts' carriers.

Apple's initial developer beta release for iOS 27 has inadvertently removed the recently implemented end-to-end encryption for Rich Communication Services (RCS) messages. This feature, crucial for securing conversations between iPhones and Android devices, is absent in the first beta build.

Sources from Apple suggest this is not a permanent deprecation but rather a common occurrence during the early stages of beta development. The company often branches new major versions from internal builds, where some functionalities may temporarily disappear before being reintegrated in subsequent updates. The aim is to avoid shipping an unstable or incomplete encryption feature in a public beta.

End-to-end encryption for RCS messages was a significant addition, first appearing in iOS 26.5. This upgrade ensures that 'green bubble' chats, which previously transmitted data in plaintext, are now protected. However, the actual encryption of a conversation depends on the compatibility and support of the mobile carriers involved for both sender and receiver. Users needing this security feature are advised to avoid the current iOS 27 beta and remain on iOS 26.5 until its confirmed return.
