hi there, could some one help me work out how to control the duration of the bottom touch capacitive keys on my lg p920 3d, as they only stay on for 6 or 7 sec, i need them to stay on while im using it,as at night its just not possible to know where the keys are!my old lg p970 black had it and the led lights would stay on really dim but enough to see them,so if you can post a link or know of a app that can do this let me know
