If u have to switch on / off your sensors, you have to go all the way from Menu>Settings>Phone>Sensor Settings>Sensor on/off… If u install this app in ur device and put a shortcut of it in ur HS, then juz one click is enuff to on or off ur sensors… Its actually FP2 version, but I installed it and working fine on N8…While installing u will get a pop up message that; Application is not compatible continue anyway, press ok and continue installation.
