    There is a solution; (not sure about it, my friend had the same problem and he fixed it with this method)

    Open dialer menu and type;
    5689#*980# (Sprint)
    3845#*801# (T-Mobile)
    3845#*803# (AT&T Canada)
    3845#*802# (International)
    3845#*800# (At&T)
    3845#*980# (Verizon)

    And when hidden menu is showed up, go to "Settings"
    and go to "Update Touch Firmware".
    The touchscreen won't work until after 5 seconds, Wait for it and if touchscreen gets working, exit the menu.
    Lock the phone and try knocking on the screen, It should be working

    Thanks mate! Works fine for me. LG G2 D802 Int.
