But for most users, the button was useless, so they started downloading third-party apps that allowed them to remap the button to launch any app.
But now Samsung finally officially allows us to deactivate the button. We waited half a year before Samsung came up with such a really simple solution, but at least something. Samsung won't let you do anything other than disable the button, even though users want the official option to remap the button all the time.
