Google is enhancing the Call Screen feature in the Pixel Phone app with 'AI Replies.' This feature will allow users to respond to calls without answering, using AI-generated smart replies based on the caller's responses. Code strings related to AI Replies were discovered in the latest beta version of the Phone app, indicating that Google may utilize its Gemini Nano technology for this functionality. Users will have the option to enable or disable AI Replies. Details on how these AI responses will differ from current options and the timeline for public release are not yet available.
