How to install double-tap on back gesture on your Android

Hi, how are you? The double-tap on back gesture is one of the new functions available on Android 11 and IOS 14. This function allows you to perform different actions such as launch the assistant, activate shortcuts, turn on the flashlight among other things. In this post, we will show you how to install the double-tap gesture in almost any Android device.

This is possible thanks to an app called “Tap, tap”. This application is a port of the function included in the latest versions of Android. Also, this app makes use of the same algorithm and artificial intelligence directly taken from Android 11 builds, through machine learning is capable of indicating to our accelerometer where we are touching. This app is being developed by Kieron Quinn recognized developer of the XDA Developers forum and with the collaboration of other users.

Besides this app adds even more features than those available in Android 11 and IOS 14. The only requirement is to have a device that runs Android 7 or higher. By the way, this app is in Alpha state so some features may not work properly.

Adding Actions

The Actions are tasks that are executed when you press the back of your device twice. Actions are executed in the order listed – top to bottom. If an Action is successfully executed no further action will be performed. However, if an action is not available (for example if the camera is already running), the next action below will be executed, so it will be until action is successfully executed.

To add an action go to the main menu-> to the Actions section. Then press the + Add Action button, the app will show you four more buttons. Each button will display a list with different actions, you can choose the ones you want.

The Gates are situations that can block the gesture from executing any action. For actions to be executed, all enabled Gates must be open. For example, if you are in a call and the On-call gate is enabled, no action will be executed.
