AT&T LG G2 Knock Code

A quick heads up for those of you rocking the LG G2 on AT&T: If you haven't already noticed, there's a system update waiting for you. And that 39-megabyte update brings forth one of our favorite features of the year — Knock Code.

Knock Code expands on the "Knock On" tap-to-wake feature by adding in the ability to tap in a pattern, adding in another level of security. Give it a whirl and see what you think. And swing by our LG G2 forum if you've got questions.

Phil! If i have an unlocked AT&T LG G2, can i get the update just by inserting an AT&T sim card on my phone?
I don't want to reinstall the whole software again just to get knockcode.

Lock screens in general are so silly. Nobody cares to get into your phones, people. Except maybe your untrusting significant other.

Get a job with confidential info that comes and goes through emails and you would think differently

Are you that stupid? Just imagine what someone could do if you loose your phone is extreme... mails, messages and calling some expensive numbers.

How ignorant. If your phone is a BYOD for your work, then you'd be singing a different tune.

well at least it sounds like an easy enough fix. I will look into this tonight at work! thanks! been waiting for Knock Code.

It seems really slow. Like a looooooong lag between entering the code and actually unlocking the phone. Can we get some scientific testing of this? A speed test? Phil?

Man, I was really hoping this update would give us the multitasking button!

Since installing this update, I am no longer able to access the camera from the lockscreen or add / remove lockscreen widgets. This is the case no matter what lock screen security settings I use. Anyone know if there's a fix for this? I have found nothing.
