With the release of the Android 11 developer preview, Google was discovered to be testing a software feature called Colombus gestures, which allows users to input a double-tap through the back of a smartphone, triggered by the accelerometers in the device.
With the second release of the Developer Preview, more hints arrive regarding the Colombus gesture. These hints reveal that Colombus is being tested on the Google Pixel 3 XL, Pixel 4, and Pixel 4 XL. Two new actions were added as well: screenshot, and recent apps. In addition, Google has refined the feature to prevent false inputs all this according to XDA Developers.
Colombus uses information from the devices accelerometer and gyroscope sensors to interpret when the user has double tapped. In addition, the gesture will not work under all conditions, like with the screen turned off, the camera active, or at the lockscreen as to prevent unnecessary battery drain and accidental inputs.
In addition to the new gestures mentioned above, Colombus gestures can also trigger the camera, dismiss a timer, launch Google Assistant, play/pause music, collapse the status bar, silence incoming calls, snooze alarms, perform a user selected action, and unpin notifications.
According to XDA Developers, Pixel smartphones since the Pixel 2 and 2 XL already have the hardware needed to support this feature and XDA has even been able to get the feature to work on a Pixel 2, but it will be up to Google to officially implement it in legacy Pixel devices.
