Apple has released the first developer beta for iOS 26.4, revealing upcoming features for iPhone users. The update follows iOS 26.3's recent launch, which introduced Android file transfer capabilities and weather wallpapers.

The new beta includes encrypted RCS messaging for better cross-platform communication and enhanced Apple Podcasts with advanced video podcast features. Apple Music will receive a visual upgrade with full-screen album artwork, while the Wallpaper Gallery gets a redesigned interface for easier customization.

Reminders gains a new Smart List for urgent tasks, building on functionality introduced in iOS 26.2. The update also reportedly enables Stolen Device Protection by default, requiring biometric authentication away from trusted locations. While some features may change before the final release, the beta suggests Apple continues prioritizing both user experience and security enhancements for its mobile ecosystem.
