LG 韓國發出新聞稿，旗下的 L Series II 系列手機將會在一月獲得新，並會添加 Knock 功能 (即之前稱作 “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，在手機屏幕上輕敲下就可叫著手機屏幕。這個 Knock 功能隨後亦在 G Flex, G Pad 8.3 上推出，現在 Knock 功能就進一步擴至其他機種。根據新聞稿，LG L Series II 將會在一月會有一個全球性更新，到時就會添加 Knock 功能。
