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.
