The first phone in the Series III range to hit the market is already known, once the three that comprise it were seen at the Mobile World Congress. We refer to LG L90, which is a model that includes the Knock Code functionality that allows the terminal to "wake up" by means of a code of keystrokes on the screen.
It is a security solution based on combinations of touches on the panel that improves quick access and adds an extra layer of protection against accidental unlocking.
This is a phone from Midrange which is initially being sold in Russia and neighboring regions, but it has been announced that it will soon be available in other locations, including Spain.
