LG Knock Code is the extended version of Kock On feature, which was introduced in 2008. LG says that the new Knock Code feature provides a higher layer of security and convenience to users over conventional password and pattern-based security options.
The Knock Code feature essentially divides smartphone's display into four invisible quadrants and allows users to both power on and unlock the LG smartphone by tapping a personalized pattern on the phone's screen.
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 a level of security far greater than other devices, even those with fingerprint recognition systems. 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.
