iOS 26.4 beta 1 just landed for developers, and there are a bunch of useful features to try out.
The first developer beta of iOS 26.4 is here, offering a new video experience for Apple Podcasts, support for testing end-to-end encrypted RCS messaging, and much more.
OS 26.4 enables Stolen Device Protection by default, adding biometric verification and security delays to critical iPhone settings, alongside encrypted RCS and Podcasts video support.
