LG to add Knock Code feature to LG G2 and G Flex in April

LG today said its Knock Code feature will be added to existing owners of LG G2 and G Flex in specific countries via a firmware update starting in April.

The Korean smartphone vendor at the Mobile World Congress 2014 said that Knock Code, which will give users instant access to their smartphones via a customized knock pattern, will be a key feature in LG smartphone models this year, including G Pro 2, G2 mini, F Series and L Series III.

More than 50 percent of participants in a recent survey selected Knock Code as the most anticipated feature of G Pro 2, demonstrating the real need for an alternate solution to smartphone security.


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 better than other devices.

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.

LG said Knock Code is also more responsive compared to bio-recognition systems, which are much more susceptible to variations in the environment.
