Apple has rolled out iOS 26.4 developer beta 4, removing the end-to-end encryption feature for RCS messaging that appeared in previous beta versions while expanding compatibility to include the newly launched iPhone 17e.
The encryption option, introduced in earlier 26.4 betas, was intended to enhance privacy in RCS messaging for cross-platform communication. Its removal follows Apple’s confirmation that encrypted RCS messages will not debut in the final iOS 26.4 release and will instead arrive in a future update. Testers report that the Messages setting for encryption has disappeared in the latest build.
The update also introduces eight new emoji designs drawn from the Unicode 17.0 standard, including Distorted Face, Fight Cloud, Orca, Ballet Dancers, Hairy Creature, Trombone, Landslide, and Treasure Chest. These emoji, previously visible only as placeholders, now appear in their finished artwork within the keyboard.
Apple has additionally made a minor accessibility modification, renaming the “Reduce Highlighting Effects” option to “Reduce Bright Effects.” The feature, found in Display & Text Size settings, reduces the brightness of on-screen animations and flashes in line with the company’s broader visual refinements under iOS 26’s Liquid Glass design.
Beta 4 marks the first version of iOS 26.4 available for the iPhone 17e, following the handset’s addition to the iPhone 17 lineup. The release comes one week after Apple issued a revised third beta on March 5.
Apple historically finalizes its x.4 software updates in March, and iOS 26.4 is expected to follow that timeline. The public release will include new features such as the AI-driven Playlist Playground in Apple Music, updated album and playlist designs, CarPlay video support, and default activation of Stolen Device Protection. End-to-end RCS encryption, however, will roll out at a later date.
