Consumer devices
In 2009 KT was the first network to introduce the iPhone. The origins of South Korea's domestic smartphone production industry can be traced to Samsung's release of their first smartphone, a reaction to Apple's iPhone, which was well-received by the South Korean population. Later, as the smartphone sector kept growing, South Korean LG Electronics also participated in this competition. Compared to Apple and Samsung, LG had a different business strategy, which was to make devices with lower price and better functionality rather than with high specs; however, as LG started to focus on better camera functions and screen quality with better pixel, their cost of goods started to increase but the sales was not so much improved. As the result of continuing net loss in smart phone business, LG announced its decision to exit this area in April, 2021. Up until this time, Apple and Samsung has remained the two companies with the largest market shares, and LG had only cornered a small portion of the market. Apple knew this event was a chance to increase their sales in South Korea and tried to take this opportunity by renting LG’s display spaces in markets. Samsung also acted by trying to tempt LG smartphone users by offering them good deals on their new Samsung phones, for example, by running trade-in events for used LG smartphones. Competition between the two manufacuters in the South Korean market is still on-going. Network and service developments
