LG 韩国发出新闻稿，旗下的 L Series II 系列手机将会在一月获得新，并会添加 Knock 功能 (即之前称作 “KnockON”)。
popular Knock feature (formerly known as KnockON) will be included as a standard feature in the company’s key mobile devices in the future while its line of L Series II smartphones will receive Knock through a global Maintenance Release upgrade starting in January 2014.
Knock 功能最早在 LG G2 推出，在手机屏幕上轻敲下就可叫着手机屏幕。这个 Knock 功能随后亦在 G Flex, G Pad 8.3 上推出，现在 Knock 功能就进一步扩至其他机种。根据新闻稿，LG L Series II 将会在一月会有一个全球性更新，到时就会添加 Knock 功能。
