Apple is preparing to roll out iOS 26.2, and new reports suggest that the expected release window along with a feature that could change how iPhone users interact with voice assistants. The update is set to introduce an option that has never appeared in earlier versions of iOS, which will let users in select regions choose a voice assistant other than Siri.

New Voice Assistant Option
In the latest update, Bloomberg’s Mark Gurman noted a key change Apple is preparing for iPhone users in Japan. Currently used to launch Siri, the side button will allow users to select a third-party voice assistant. This marks the first time Apple has opened the iPhone’s hardware button to alternatives.
According to Gurman, the iOS 26.2 beta includes a developer framework that lets third-party assistants respond through the side button. Apple introduced the extended side button with the iPhone X in 2017, and Siri has remained its default function since then. Regulatory pressure in Japan has prompted Apple to expand this function, at least in that region for now.

Gurman also expects this flexibility to reach the European Union in the future, even though it will not be part of iOS 26.2 at launch. In the U.S., users can continue accessing options like ChatGPT or Gemini through the Action Button on supported iPhone models.
