    Backlight remains on after locking the screen in Karbonn A21

    The backlight of my Karbonn A21 remains on after locking the screen. Even after locking the screen, it gets on all of sudden after pressing couple of times. Everytime, I try to send a query about the same through chat, no solutions ever comes. How to fix this snag? Please suggest.
