I was able to turn off the haptic vibration for everything else, namely the keyboard, but I can't turn off the vibration for the 4 buttons (home, menu, back and search). Am I missing something or is there really no way to turn that off?
Its there. I was looking for it under display but 15 mins, because it would make sense for it to be there due to the fact that it has NOTHING to do with sounds.
Re: Can you turn off the haptic vibration on the 4 android button
Yes, Settings>Sound> Scroll all the way down and turn off vibrate feedback. Make sure you turn it off on the keyboard you choose to use as well or it will be on the keyboard too.
