But the company will be also offering the feature to owners of LG G2 and G Flex in specific countries.
The Knock Code update which will give users access to their smartphones via a customized "knock" pattern. KnockOn, which LG patented in 2008, is unique in its ability to both wake and unlock the phone in one step. With Knock Code, the smartphone display is divided into four invisible quadrants. The user taps or "knocks" anywhere from two to eight times in the quadrants in a specific sequence. With more than 80,000 possible combinations and no fingerprint streaks, Knock Code offers security. And because Knock Code can be implemented anywhere on the screen in any size without having to view the screen, there's no chance of password theft. In addition, LG claims that Knock Code is more responsive compared to bio-recognition systems.
