The Gemini overlay on Android has been updated to include a new shortcut that allows users to quickly open the full Gemini app via a drag handle at the top of the overlay. This feature provides access to chat history, Gems, and settings. The updated prompt bar offers seamless access to features like Video, Deep Research, and Canvas chips, while the design of the 'plus' menu has been refreshed. The overlay shortcut is being rolled out with versions 16.27 (stable) and 16.28 (beta) of the Google app, and users may need to force stop the app to activate it. Additionally, the overlay now supports right-alignment on tablets and foldables.
