With the LG G2, the Korean company introduced a nifty double-tap to wake and sleep feature. Soon after, the company introduced Knock Code on the G Pro 2 and other devices that allows users to wake up and unlock their device by tapping in a certain pattern on the screen.

Now, LG has announced that it will be bringing Knock Code to the G2, as well as the G Flex, via  firmware update that is scheduled to start from sometime in April in some “specific countries”.

According to LG’s press release, Knock Code offers a greater level of security than fingerprint recognition systems and is much faster  as well.

“LG engineers placed a great amount of emphasis on providing users with exceptional security and convenience when developing Knock Code,” said Dr. Jong-seok Park, president and CEO of LG Electronics Mobile Communications Company. “Making Knock Code accessible to a wider audience is consistent with our direction to differentiate LG mobile devices on the basis of user experience.”

Knowing LG, expect the software roll out to first begin in the Korean and Asian markets followed by the USA.
