Google have on their cell phones Pixel a rear button that allows the user to set any function they want. But for those who have an Android phone of any other brand, this trick also works.
The only two conditions that exist are: the cell phone must have the Android 7 update or more and the mobile must have an accelerometer and gyroscope, something that is common in recent models. In case of not complying with the specifications, the same platform will show a notice limiting access to its functions.
With the requirements ready, you can take advantage of the ‘secret button’ to configure up to 50 actions with two or three touches on the back of the phone, having direct access to basic functions or access to third-party applications.
How to activate the secret button of Android
The first thing to do is download the application, which is not found in any virtual store, such as Google Play Store or that of some cell phone brand. Therefore, the APK, the installation file, must be obtained in the repository GitHub and search Tap Tapthe name of the app.
After downloading and installing it, it will appear along with the rest of the platforms that are on the cell phone and the next step will be to configure it, since the application will ask for Internet access permissions to carry out updates and find out the specifications of the phone on which the app runs.

Then it’s going to test the back gesture operation, so it’s going to say hit the lid two or three times. If there is an error at that time, the configuration can be done from the option Gesture Configuration which will appear at the bottom of the screen.
Then the final part will come to choose the different actions that will be given to the gestures, there are 50 possibilities in total and you can have one for the double touch and one for the triple.
Among the options provided by the application is the possibility of opening third-party applications, Android functions, changing buttons, among others that will be activated once and there will be no need to Tap Tap every so often, unless you want to make changes to the button.
Another important configuration is to limit unwanted gestures, that is, it can be blocked at times such as when the cell phone has the screen off or when listening to music, with the aim that the functions are not activated at inopportune moments. This tool is called Gates.
