LG Zero is a mid-tier, slim metal phone that uses real metal and 2.5 D glass to give it a slimmer, streamlined appearance as well as a firm grip. The pressed metal body reduces material costs, with the 2.5 D glass giving the front surface a distinct look. The metal décor on top and bottom also serves as an antenna. The luxurious eco-friendly metal body appeals to consumers with its sleek look and texture.
