LG G3 is an Android smartphone developed by LG Electronics. First released in South Korea on May 28, 2014, it is a successor to 2013's LG G2. Inheriting design elements from the G2, such as its thin screen bezels and rear-mounted power and volume buttons, the G3 is distinguished primarily by being the first smartphone from a major manufacturer to incorporate a 1440p display, and its inclusion of an infrared hybrid autofocus system for its camera. LG also touted the device's plastic "metallic skin"—designed to give the device a higher quality appearance, and a "simpler" user interface with an integrated intelligent personal assistant system.
