LG has today announced, that due to popular demand it has now decided to make its Knock feature, which debuted on the G2 back in August, a standard addition to all L Series II smartphones. For those unaware, this “convenient” function allows its users to lock and unlock their handsets by simply double tapping on the screen of their device.

Mobile World Congress is right around the corner, but it appears some manufacturers simply cannot wait to show you their latest offerings. LG has this morning announced its new Optimus L Series II family, which includes three devices called the L3II, the L5II, and the L7II. They range in size from 3.2 inches to 4.3 inches, and it’ll be the the largest model, the L7II, that is available first.
