Apple has released the first iOS 26.4 beta for iPhone, marking the latest development in the company's software testing cycle. The update arrives as Apple continues refining its mobile operating system ahead of a wider public release.

Originally, expectations were high that iOS 26.4 would introduce upgraded Siri capabilities powered by Google Gemini. However, recent reports indicate those anticipated AI features have been delayed beyond this beta release. The postponement suggests Apple is taking a cautious approach to integrating third-party AI technology into its ecosystem.

While specific new features in this beta version weren't detailed in the initial announcement, beta releases typically include under-the-hood improvements, security enhancements, and refinements to existing functionality. Developers and public beta testers can now download iOS 26.4 beta 1 to evaluate the update's performance and provide feedback to Apple before the final version reaches all users.
