Don’t buy a budget Android phone in 2026 — 4 reasons to get an old flagship instead

Google's Pixel phone introduced a Quick Tap feature, allowing users to double-tap the back of the device to trigger actions. However, this feature is exclusive to Pixel phones, leaving other Android users unable to access it. An open-source app named Tap, Tap offers a solution by bringing Google's back-tap gesture to a wider range of Android devices.

Tap, Tap can be downloaded from its GitHub repository, where users can also find release files and installation instructions. This app supports Android 7.0 and later versions, provided the device has an accelerometer and gyroscope for accurate gesture detection. Once installed, users can configure the app to assign various actions to double or triple taps on the back of their phone.

The app supports over 50 actions, such as launching apps, toggling the flashlight, simulating button presses, and running Tasker tasks. For instance, one user assigned double-tap to launch a preferred assistant, which then opens the app for quick access to various functions. Another user set triple-tap to take a screenshot, providing a convenient alternative to pressing the power and volume buttons simultaneously.

Tap, Tap offers flexibility through its Gates feature, allowing users to set conditions for when back-tap gestures should trigger. This can help reduce accidental triggers and ensure the shortcuts behave as intended. The app can also integrate with Tasker, an Android automation app, enabling users to create complex sequences of actions for specific routines.

For example, a Tasker task could automate tasks like turning on Do Not Disturb, adjusting media volume, and launching a reading app with a back tap. However, configuring these custom automations requires using Tasker separately.

Overall, Tap, Tap provides a versatile and customizable way for Android users to trigger actions by tapping the back of their device, offering a practical alternative to the exclusive Quick Tap feature found only on Google Pixel phones.
