Did you try the Hidden Menu trick? that works for many if not all.

try 3845#*modelnumber# eg: 3845#*800# change model number 800 with your phones model number, then tap on "Settings" and scroll down to "Update Touch Firmware"

I'm on a US Sprint LG-G2 and folllowing beezar's advise was able to get into the proper hidden menu. I went ahead and updated the Touch Firmware but still no go. 2 questions:

1. What is the correct firmware version that will fix the knock on issue?
2. Does the proximity sensor have any effect on knock-on? I just recently replaced my screen and think I may have damaged the proximity sensor. When I use one of the proximity sensor tests it never seems to work. Stays at 0cm.

Thanks for any help!

I think the proximity sensor DOES affect the knock-on feature. My knock-on works fine, but if I put one hand over the proximity sensor it won't wake on a double-tap (probably to avoid accidental wakes when the phone is in a pocket).

Thanks.

I see now where the issue lies. When I put the screen on I must have had too much adhesive on the top portion because it does look a bit raised. If I push down on the left corner and then double tap phone turns on. Looks like I'm going to have to take the screen off and add more adhesive.

I'm having the exact same issue, and haven't found an easy way around it yet. There is the hard way, but I don't trust myself enough to do that! :P

I'm very surprised this is still a pervasive issue. My knock-on function disappeared when Kit Kat showed up and never came back. And, knock-off works just fine, so it can't be hardware.

I've tried the fixes using the proximity sensor. None are that responsive and they all eat battery life. Not sure if Sprint or LG will every solve this issue.
