The back button annoys me in some apps so I want to disable it in certain time and will enable it later. Is there any way to do it ?
p/s : I use Galaxy Note 2 N7100 with Android 4.1.2, rooted.
It depends upon when would you like to disable the back button and how would you want to do that.
Also see my answer for Is there a way I can prevent the back button from going to the home screen?
