When LG first showed off KnockCode, their tap-based pattern unlocking mechanism for devices that support KnockOn, they promised it’d be headed to many of their latest smartphones. The LG G2 certainly wasn’t going to be left out as it was their 2013 flagship, but it seems to be taking quite a bit of time to make its way to all of the variants swirling about.
Sprint’s version can finally add itself to the list as KnockCode is the feature attraction in a new software upgrade going out today. You can see the feature in action on the LG G Pro 2 in the video above. While not mindblowingly different from a traditional swipe to unlock pattern, LG touts KnockCode as more secure because it doesn’t leave drag marks that can tip a would-be snooper off to your lock-screen pattern.
The software version for the upgrade is ZVD, and aside from the aforementioned addition of KnockCode we aren’t treated to much. We’re sure there are many under-the-hood changes that users won’t really notice, but whatever they are Sprint didn’t feel it necessary to list them.
You can check for the upgrade by heading to Settings > About Phone > System Updates > Update LG Software. We can’t imagine the upgrade is very big, but it’s worth charging your phone up a good deal and hopping onto a WiFi network just in case.
