    Well, removing the knock code gives it the chance of the knock on working, but it's still too unreliable, sometimes working but more often requiring many tries over and over before it finally wakes up. I've decided to use a small neodymium magnet attached to the end of a stylus to wake it from its slumber instead, passing it briefly over the quick circle sensor on the center of the left edge of the screen.
    That immediately wakes it up each and every time. That'll have to be my workaround for the unreliable knock on implementation, until LG figures out how to correct it.

    I'll admit my trouble and my new glass protector did arrive at about the same time but, if my protector is the issue why am I able to double tap to put my phone to sleep?

    I had this problem... Just replaced the frame/screen assembly, and problem is gone.

    After 15 months, is your device still working with the KnockOn? Thinking about replacing mine to fix it.

    Mine was sent in for the boot loop issue and the knock on feature didn't work properly before or after the repair, I don't know if it's a firmware issue or not. Maybe they disabled it because it caused battery drain when constantly monitoring when off or something. Kind of a neat feature, but it doesn't work for me.

    I wouldn't bother trying to get it working. I just use the back button and changed my phone mount so that it's accessible when mounted, as a workaround.

    Thanks LonerangerVII! Changing back to swipe helped on my LG G4. It doesn't work perfectly, sometimes takes a few tries but it's better. Seems weird since the double tap to shut down has always worked fine. I agree that a screen protector is not the cause as I've always had one on, and the problem just started recently. Resetting to factory didn't help either. This will be my last LG, they have too many bugs and known issues but sell the phones anyway.
