Google's Pixel phones come with a hidden gem called Quick Tap, a feature that allows users to perform actions by double-tapping the back of their device. While it's a handy feature, it's not exclusive to Pixel phones. The article introduces an app called Tap, Tap, which offers a similar back-tap functionality and more. The author, Ryan Haines, is a fan of the Action Button on iPhones and believes that a similar feature on Android phones would be a game-changer. Haines suggests that phone manufacturers should offer Quick Tap as a built-in feature, and Google should bring those missing features to its Pixel phones. The Tap, Tap app supports double-tap and triple-tap gestures, allowing users to perform multiple actions with a single gesture. It also includes gates, which let users specify situations when they don't want gestures to trigger certain actions. The app offers over 50 actions across various categories, and users can unlock more actions using the Shizuku app or by rooting their phone. Haines provides a step-by-step guide on how to set up and use Tap, Tap, including granting permissions and configuring actions and requirements. He concludes by expressing his desire to see Tap, Tap's functionality on more phones and for Google to take note of the app's potential.
