How to disable KnockON (double tap to wake) on the LG G4, LG V10, other LG smartphones

LG's smartphones have long featured the so-called KnockON function. It's what you would call a "double tap to wake" – when the phone's screen is off, you just tap on it twice, and the device wakes up. Alternatively, if the phone is on, you knock twice on an empty spot in the home screen and it will go to sleep. It's a pretty convenient way of controlling your device, especially since smartphones are now bigger, a bit more cumbersome, and you don't always have an ideal grip on them, with a finger right at the power button.

However, if there is one thing Android users love, it is to have control over everything their smartphone does and doesn't do. Some would love to be able to disable KnockON mostly for battery-saving concerns, or to avoid accidental wakes. Unfortunately, one can't just find KnockON in Settings and turn it off.

On the LG G3, it was possible to deactivate the feature from the phone's hidden Service Menu, but the option is gone from the same menu in the LG G4 and V10. So, how do we find it? Thankfully, there's a 3rd party app that can help us out!

Sorry, but that is super stupid that you have to install an app to access certain settings. Especially when older versions of the phone had the option out of the box. I'm not very well versed on Android, is this common among devices and manufacturers?

I'm almost certain there's a way to disable this feature in settings...

Unless the option is enabled in some region- or carrier-specific G4 or V10, I would have to disagree.

When I had a G3, if the phone was in my pocket and was sweaty at all (walking or hiking on a warm day), it would turn itself on and make emergency calls. That's why.

Did you know that having an AMOLED display you are able to have this feature through an app... I can't remember the name but for those type of display you can enable it

This article doesn't make sense.

seems like a great feature, but having your phone constantly turning itself on and not knowing if your phone just dialed a call and someone might hear what you don't want them to hear, or finding out you killed off 20 percent of your battery while it was in your pocket on the way to a long flight, not worth it. THANK YOU so much for this article and informing us of how to disable this beyatch. I think I will pass on LG from now on. This phone is laggy and bug ridden. My last lg g2 just stopped working and was in mint condition. I think I am done with LG and going back to try other android brands. As long as it's not krapple I am straight!

I used to keep double tapping my old nexus tablet when i was using the G2 same time. Only then i realized, how important the knock on became. I don't understand why anyone would want to disable this simple but brilliant feature!

"However, if there is one thing Android users love, it is to have control over everything their smartphone does and doesn't do." ...Exactly! For me at least there is a reason to turn this off. My dang V10 keeps turning on when I am doing yard work and listening to music with it in my pocket. Had the flashlight on once when I pulled it out and a text message with like 100 random charters in it. This worked like a charm, thank you. There is probably a way to get to this setting but this app is small, in the approved store, and requires no permissions. For V10 users, if you would like your shortcut on your second screen, you can drag your icon the app shortcut section if and only if your app shortcuts are not already full. Otherwise, you will need to delete one from the settings first by: 1. Going to settings->second screen->choose "When the main screen is on"->tap App shortcuts settings icon. 2. Click the trashcan icon on the top right and then choose which one to delete. 3. If you try to add the shortcut back through here it won't let you because its not an app, so go back to your home screen and drag it to your second screen. It should work then.

Greets- How about the times when I pick up or set down the phone and it turns itself on or off? How about the times when I have to double tap 3 or 4 times to turn the phone on or off? It's frustrating, aggravating, and obnoxious all because the manufacturer or software engineer(s) can't perform their due diligence to make a "feature" reliable and consistent. I find it irritating and want it off.
