LG tries very hard to convince us that its 160 pounds budget phone is worth buying. The company’s latest trick to coerce us into getting one – or to wipe the tears of those who already have – is to update its operating system to 8.1. The update is already available in South Korea; it should reach European markets in a few months. 8.1 update brings a slew of changes with it, like new options for LED flash camera or the stereo DTS:X 3D sound.
