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