The Nexus 5 is a smartphone co-developed by Google and LG Electronics that runs on the Android operating system. It is the fifth smartphone in the Google Nexus series, a family of Android consumer devices marketed by Google and built by an original equipment manufacturer partner.
The Nexus 5, unveiled in October 2013, is the first device to feature Android 4.4 KitKat. Its hardware is similar to that of the LG G2, with a Snapdragon 800 system-on-a-chip, and a 4.95-inch 1080p display. The exterior is made from a polycarbonate shell (similar to the Nexus 7), unlike its predecessor, which used a glass-based construction. The Nexus 5 also supports LTE networks, unlike the Nexus 4. A revised version of Nexus 5, featuring bigger speakers and microphone holes, as well as better fitting buttons and SIM card tray, was released in December 2013.
