How to enable and setup the Knock Code feature on the LG G4

How to enable and setup the Knock Code feature on the LG G4
The last few generations of LG flagships all come with a nifty lock screen feature (Knock Code) that allows you to unlock your phone with a predefined 4-tap pattern even when the screen is off.

It's undoubtedly a nifty feature, and while it's not as secure as the PIN code one, it's a bit cooler than the regular screen swipe that is widely adopted by the majority of Android users.

According to LG, there are Code 86,367 unique pattern combinations for Knock Code, making it a tough nut to crack by unauthorized users. 

Have you ever wondered how to actually setup said screen lock functionality on your G4? It's downright easy and today we will cut your teeth in managing it. Just check out the gallery below and simply follow the steps right below.

This feature is really awesome, Android M should bring it to all devices.

I'd take the knock code over finger print scanner any day! I never use it.. if you have the slightest bit of moisture on your hands, the N4 scanner will NOT work. Knock to unlock should be on EVERY android phone.

Your scanner SUCKS. The new one touch scanners work perfectly and make knock useless.

Knock Code is an amazing feature, I love LG, but even so they should add Fingerprint Scanner, I know this is kinda generic comment, but the more feature you have, the most sales you get, Fingerprint is calling attention now, Lg should add it on next G phone so they can get back on sales race, LOVE LG !!!

Knock code was always glitchy for me. I would prefer the fingerprint scanner myself.
