The four-color microphone button on Android homescreens has been updated to provide four distinct functionalities: Search, Translate, Live, and Create. This redesign includes a mode switcher similar to Google Lens, allowing users to select their preferred mode instead of relying on the app to infer intent. Each mode is powered by different AI architectures: AI Mode uses Gemini 3.5 Flash for complex queries, Search Live employs Gemini 3.1 Flash Live for real-time conversations, and Song Search identifies melodies using machine learning. The toolbar now remembers the last selected mode, enhancing user convenience. The new features are currently available in beta versions of the Google app (17.1 and 17.2) on Android, with no specified timeline for broader rollout.
