If you change Android smartphone and you find that the buttons at the bottom are inverted with the one to exit on the right and the one to see the recent apps on the left or if you want to take a picture simply by pressing one of the physical buttons of the mobile phone or if you want to keep a button always ready to turn the flashlight on and off, you need to remap the phone button. This can be done using some applications that can change function to the physical buttons of the phone and to the fixed touchscreen buttons at the bottom, to make them do different things than they do in the default mode. There are at least three applications that allow you to swap the keys of your mobile phone or remap the function of the physical ones such as those of the volume, of recent apps and the one to go back (without root) and work well especially on Samsung Galaxy smartphones .
