Video: LG’s “Knock Code” feature

Posted Feb 18, 2014

The LG Knock Code unlocking feature was announced when the company revealed the G Pro 2 phablet. Above is a video demo of how it works. You will notice that the phone unlocks after the user knocks on the phone four times, which is this user’s custom setting. This feature is not hardware restricted so it may be added to the LG G2 in the Android 4.4 update.
