According to Android Headlines, Google has started testing and gradually rolling out a new bottom navigation bar layout in the latest version of Chrome for Android (Chrome 150), introducing a dedicated Gemini AI quick button for the first time.

This move marks a structural transformation in AI interaction on mobile browsers. The new Gemini is no longer limited to providing basic summaries of a single active web page, but can now cross-reference, compare, and summarize content across multiple open tabs, successfully replicating the desktop version of Chrome's sidebar deep search experience on mobile devices.

This design was first discovered by tech leaker Leopeva64. Currently, it is only available to users who have set the navigation bar at the bottom of the screen. The button is cleverly placed between the "Home" and "Tabs" icons.

In addition to the AI button, this update also optimized the basic navigation elements. A dedicated back button has been added to the left of the main address bar, and the three-dot settings icon has been moved to the far right. It is reported that Google has been internally evaluating this feature for about three months. With the previous desktop version update resolving regulatory obstacles in the UK market, Google plans to globally roll out this advanced mobile layout to iOS devices next month.

This upgrade is not only a strategic expansion of Google's effort to place AI at the core of the mobile ecosystem, but also drives the evolution of mobile browsers from "single-page browsing" to a productivity tool for "multi-source information aggregation and analysis," reshaping user efficiency in accessing and processing online information on mobile devices.
