Google is reportedly testing an interesting new gesture for its Pixel smartphones that lets users double-tap the back of the handset to control various functions. XDA-Developers discovered the new gesture system, codenamed “Columbus,” in the Android 11 developer preview for Pixel phones. According to the site, the double-tap gesture can be used to perform the following actions: Dismiss timers Snooze alarms Launch the camera Invoke Google Assistant Play or pause media Collapse the status bar Silence incoming calls Unpin notifications Other “user-selected action” The double-tap gesture apparently doesn’t require any special hardware, as it relies on the phone’s gyroscope and accelerometer. XDA-Developers managed to get the gesture working on a Pixel 2 XL and Pixel 4 XL, both running Android 11 Developer Preview 1. You can see the gesture being used to launch the Camera app in the clip below.
