I didn't add anything extra in to disable anything for
6 Marbles
Check it out, the left back and right menu thingy do nothing, and the middle one pauses the game by letting you go back to your system stuff.
If you click the game's launch icon again it resumes right where you exited the game.
Maybe its just my phone, because I didn't really test those buttons much until just now.
What does your build do now?
There may be an internal mechanism that overrides them if virtual buttons are placed at the bottom???? :-| (dunno)
As, I said I did nothing to bypass, but I do have my buttons down there next to the phones.
Quote: "I suspect that Google might frown on disabling all of the buttons. That is virus like behavior."
I agree.
I lucked out on my setup working the way it does I guess.
There is a way out other than my exit button, but not where my controls are.
