At first glance it may seem that an Android terminal is a kind of effigy monolithic, that may not be modified beyond the two or three tweaks visual that we all know, but it is not so, not by a long shot. Take for instance the buttons of Android: have functions prefixed that, in theory, can not be changed. But, as happens in other fields, the theory does not always correspond with practice. There are ways to do that, for example, pressing two times the button of volume up, turn on the flashlight of your terminal. If you know how, you can link the keypad of your Android device to almost anything. And we are here to tell you about it.
To reconfigure how they behave, the buttons of your smartphone, simply download and install an app called Button Mapper. And in case you don’t produce a lot of confidence, suffice it to say that it has been created under the protection of XDA Developers, the community of developers and users of Android largest Internet.
Once you have it installed, you will pass by a small tour that shows you the capabilities of the app and that warns: Button Mapper only works with physical buttons. Once the initial phase and with the appropriate permissions granted, this will be the first thing you see:

Keep in mind that today’s mobile phones are equipped with a reduced number of physical buttons: volume up and down and, in the case of the terminals of Samsung, the button of Bixby. These buttons have been disappearing to make way for a directly integrated in the interface of the terminal and the gesture navigation.
Now click on the button that you want to modify (in our case, we have and hold on Volume Up):
Screen of settings for the behavior of a button
Tap Customize to be able to modify their values. Now click on one of the options and you will see the following screen:
Personalization of the actions of the physical button
In our case, we have configured to open Spotify every time you double click the up button on the volume. If you click on where it says Actions you will see that the behavior of the button can be customized in many ways:
All the settings are available to customize
Button Mapper also lets you set shortcuts to system functions (such as muting the ringtones and notification of the telephone or activate the vibration mode), create shortcuts to applications (such as the one we just made) or to perform certain actions (such as turning on / off the flashlight, or access the camera app).
All this is available in the free version of the app, because to unlock features something more advanced you will need to spend per box. In any case, with the Button Mapper offers in its basic version should be more than enough.
