Using a smartphone as a remote control is nothing new for smart TVs via Google TV or Google Home. Google, however, appears ready to bring that exact same touchscreen convenience to traditional personal computers. A recent code teardown suggests that upcoming Googlebook laptops will let you use your Android phone as a fully functional wireless trackpad and navigation controller.
The Android Authority team found evidence of the feature inside version 1.0.1283.974003524 of Google’s Cross-Device Services system app. Hidden deep within the code is a tool dubbed “Cast trackpad.” The utility transforms a phone’s touchscreen into a remote pointer interface for navigating connected hardware from a distance. It’s designed to bridge the gap between Android phones and larger desktop displays.
Gestures, system shortcuts, and custom sensitivity
Early screenshots reveal a clean, touch-friendly layout that transforms the phone into an interactive input surface. You’ll get full multi-touch gesture navigation from the interface, allowing you to move a cursor pointer around, tap to click and interact with any open on-screen windows or UI elements all across the display.
To make navigation easier, Google added hardware-style shortcut buttons for “Back” and system volume adjustments. Users can also fine-tune input settings to their liking with the built-in sensitivity slider, tweaking pointer speed and touch responsiveness.
This makes the tool great for real-world situations such as managing a presentation connected to a projector or changing apps from the other side of the room without walking back to the desk.
Deepening the Android-to-Googlebook ecosystem
The timing of this discovery aligns with broader efforts to build seamless cross-device continuity. Alongside the trackpad interface, the report revealed updated onboarding screens for “Cast My Apps.” The latter is designed to stream mobile applications directly from an Android phone onto a Googlebook desktop, as well as task-switching tools like “Continue On.”
Multiple manufacturers are expected to launch Android-based Googlebook laptops this fall following Google’s September 15 media event in New York City. Meanwhile, these hidden Cross-Device Services tools show how Google plans to link mobile and laptop hardware together. Google is clearly taking direct aim at Apple’s ecosystem continuity.
