If all of you LG G2 users were starting to doubt if you would ever get to use LG’s patented Knock Code feature – one of those features that was initially available in LG’s flagship G3 this year but was promised to trickle down the product line – this should be a breakthrough day for you, or at least when you read this article. Yes, an update has dropped for AT&T‘s LG G2s that primarily brings the much-hyped feature to its users.

The official update from AT&T dated June 11th now brings the Knock Code to the G2, LG’s highly successful 2013 flagship. We officially heard about the move that LG will let the feature trickle down to its other units in March, but we haven’t heard much about it since. When G2 users got the official Android 4.4.2 Kitkat update in April, most of them were hoping that the Knock Code feature would also be included in the update, but alas, it was not.

Well, the waiting is finally over now as AT&T finally put out the update. AT&T G2 owners can either wait for the update notification or have their units query for the update. If the notification comes, the update will just be a matter of clicking through the prompts. Those who have read this article and still haven’t received a notification, you can have your unit query the update servers if the update is ready. You can navigate to Settings -> About phone -> Software updates -> Check for Updates. If the update is ready for your particular unit, it should prompt you to download the update. And depending on the software version of your LG G2 phone, it can range from a measly 40MB download to a sizeable 700MB one if you have one of the older software versions.

If you’re interested to see why everybody is excited about the Knock Code, and maybe learn how to use it yourself, check out the video at the bottom of this article. The Knock Code has probably been one of the most talked about features of any LG phone. It is basically a security feature, and touting over 80,000 possible combinations, it may well be one of the most convenient ways to secure your LG handset.
