The LG G2 comes with numerous software tricks, and one of them includes the ability to wake up the device with a double tap on the screen. It’s a feature that Nokia introduced in its now-cancelled MeeGo operating system (it’s used in Sailfish, an OS a few MeeGo developers are working on), and LG was the first manufacturer to take cue and put it on one of its devices, under the name “KnockON.” Now, the Korean manufacturer has renamed it to just “Knock” and also announced that it will be making Knock available on its LG L Series II smartphones, thanks to a positive response from LG’s customers in South Korea.
Knock is currently available on the LG G Pad 8.3 and the LG G Flex as well, and the L Series II models will be gaining the feature through a maintenance update in January. “Knock is distinctively an LG UX and a great example of what happens when you marry the latest in mobile technology with consumer-centric insights. No one ever thought that a power button needed to be improved until our engineers wondered why they couldn’t turn the entire screen into a power button,” said Dr. Jong-seok Park, President and CEO, LG Electronics’ Mobile Communications Company. Of course, considering Nokia was the first to think of the double tap to wake function, it’s not really an idea LG’s engineers came up with, but it’s still a very useful one that every manufacturer should be implementing on its smartphones.
