Google Gemini Bubble UI with Gradient Design: Testing Expansion

Google is expanding its test of the Gemini overlay bubble feature. Previously, when users tapped outside the overlay, the Gemini interface would disappear entirely. Now, it collapses into a floating bubble marked by a bold spark icon. Tapping that bubble instantly brings back the conversation, making the AI assistant interaction more persistent and convenient. In the latest version, Google has also added a gradient color treatment to the bubble, matching the blue-purple gradient of the Gemini overlay for a cohesive visual identity. Additionally, some users now see a new "Minimize Gemini" button, offering another way to shrink the interface.

Beyond the bubble design, Google is testing a full-screen edge gradient animation. When the Gemini overlay opens or closes, a smooth gradient reminiscent of the Gemini branding lights up the four edges of the screen, replacing the previous four-point rotating animation. This design uses ambient color and edge focus to clearly signal state changes without distracting from the main screen content. The animation was spotted in Google app version 16.41.34 and is expected to be pushed via server-side switches.

From the bubble to the edge animation, this series of UI tweaks shows Google is building a consistent visual language for Gemini. The gradients not only make the interface feel more dynamic, but also use color changes to convey status without text, improving user perception efficiency. As the testing scope continues to widen, these design updates are likely to roll out to more users in future releases, making Gemini feel smoother, more confident, and more cohesive in the Android ecosystem.
