Invoking Gemini Live could soon be as simple as pressing your phone's power button
Or even just a diagonal swipe

Gemini on your Android device can already see what's on your screen, allowing you to probe it about the on-screen content you wish to gain a deeper understanding of. Triggering the feature is seamless — you simply call upon the AI assistant (I have Gemini set as my power button gesture shortcut), and tap the 'Ask about screen' toast prompt.
