LG G2 and G Flex to receive Knock Code in April

LG plans to bring its latest (and rather cool) unlock feature called Knock Code to the G2 and G Flex. It made its debut on the LG G Pro 2 at this year's Mobile World Congress and brought a breath of fresh air to the Android lockscreen.

The update will hit the LG G2 and G Flex as a part of a software update. Since the LG G Flex is yet to receive Android 4.4.2 KitKat, we guess that the company is planning to incorporate the Knock Code feature there. The update is also rumored to bring 4K video recording to the curved smartphone.

Since the G2 has already been updated to Android 4.4.2 KitKat, there the Knock Code feature is probably going to be delivered on its own and not as a part of an Android version update.

However, LG isn't keeping Knock Code exclusive to its premium device line-up. The LG L90 already has the feature, as do the recently unveiled G2 Mini, F90, F70, L70 and L40

For those of you that don't know what Knock Code is, it's a proprietary feature by LG, which allows you to unlock the device with a predefined knock pattern. It's more like tap code as you don't really need to knock anywhere for it to work. You just tap on any of the designated four areas of the screen in a succession of your choice and the smartphone gets unlocked without even waking up the display beforehand.

LG says there are 86,367 possible knock patterns (including 2-8 taps on the four available sections of the screen) so you KnockCode should be as secure as a password.
