Electronics giant LG, has introduced knock code, a proprietary feature which allows users to unlock their LG smartphones with a predefined knock pattern.

The new code will be key feature in the LG smartphone models this year, including the G pro 2, G2 Mini, F series and L series III. The knock code provides greater security for the user over convectional password and pattern-based security options and also gives the ability to wake and unlock the phone simultaneously providing more convenience.

"All one needs to do is just tap on any of the designated four areas of the screen in a sequence of your choice and the smartphone gets unlocked without even waking up the display screen beforehand. And because knock code can be used anywhere on the display, it's possible to access one's phone without even looking," says Joseph Kim, the LG East Africa Managing Director.

Since 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 to being safer and more convenient, Knock Code is also more responsive compared to bio-recognition system, which are much more susceptible to variations in the environment. Details of availability of the Knock Code upgrade will be announced locally in the weeks ahead.

The new version is an upgraded "sequel" of the highly acclaimed KnockON feature which debuted last year with the launch of LG G2 smartphone.

With recent consumer research showing that most users check and unlock their devices between 100 and 150 times a day, LG was inspired to further enhance its KnockON feature with a higher layer of security and convenience.

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.
