}} The LG G2 is an Android smartphone developed by LG Electronics. Serving as a successor to 2012's Optimus G and the 2013 Optimus G Pro phablet, the G2 was unveiled at a press event in New York City on 7 August 2013, and first released in September 2013. The G2 is primarily distinguished by software features that LG billed would "learn" from users, a high fidelity sound system designed to produce higher quality audio, a 1080p screen with technology that the company claimed would improve energy efficiency and reduce the size of the bezel around it, along with the unique placement of its power and volume keys—eschewing their typical location on the edge of a smartphone by placing them on the rear below the camera lens. The device was released to mostly positive reception; the G2 was universally praised for LG's efforts to produce a more seamless and compact design, its high performance, the quality of its display and camera, along with its long-lasting battery. Critics were divided on certain aspects of its design, such as its rear button layout, and its plastic chassis—which was panned for closely resembling recent Samsung Galaxy products and being a regression from the glass-based chassis of the Optimus G. Similarly, while its software and user interface was praised for its usability and large number of customization options, some reviewers felt that the software suffered from feature creep and contained notable usability regressions in comparison to "stock" Android. Sales of the G2 exceeded LG's estimates; in late-December 2013, a Korean news agency reported that at least 3 million units of the G2 had been sold worldwide. ==Release== The G2 was first unveiled during a press event at New York City's Jazz at Lincoln Center on 7 August 2013. LG announced that it would begin to release the G2 globally on over 130 carriers within the next two months, in markets such as South Korea and the United States.〔(【引用サイトリンク】url=http://news.cnet.com/8301-1035_3-57597319-94/lg-gets-back-to-superphones-with-g2/ )〕 To promote the G2, LG attempted to hold a city-wide scavenger hunt in Seoul, South Korea; during a press event at a local park on 9 August 2013, helium balloons (tying in with its "G in the Cloud" advertising campaign) were released that contained 100 vouchers. After the vouchers were scattered through the city by the deflating balloons, LG planned to give away G2s to those who found the vouchers. While only members of the media were formally invited, the event was disrupted by members of the public who learned about the promotion on the internet. As the balloons were released, attendees attempted to use BB guns and other makeshift tools to retrieve them. The resulting quarrel which broke out over the balloons resulted in 20 injuries; following the incident, LG apologized and stated that it would pay for the medical treatment of those injured in the event. LG also called off plans to hold similar events in other South Korean cities.〔(【引用サイトリンク】url=http://blogs.wsj.com/korearealtime/2013/08/17/lgs-promotional-campaign-for-g2-backfires/ )〕〔(【引用サイトリンク】url=http://www.theverge.com/2013/8/12/4613676/20-injured-at-lg-g2-promotional-event )〕 The G2 was first released in the United States by Verizon on 12 September 2013, and released by AT&T the following day.
