I just updated the Jelly Bean update and I'm still getting used to it. One thing that is really bugging me is that there is no feedback when I type something or touch the three buttons at the bottom. The option for a vibrate on touch feedback is visible (Settings>Sound>bottom of the screen "Vibrate on touch"). This option is grayed out and I can not figure out how do turn it back on. Can anyone help me? (I have a HTC One S)
