Many are aware that Android, the open source operating system that open for anyone to use, is now the leading smartphone OS. Two search engine providers in Korea appear to think this has shut them out of the exploding smartphone market. In its complaint, NHN said that Google, “through a marketing partnership with major smartphone producers,” had unfairly created “a new ecosystem” by offering the Android system free as a way to control the market. Google denied the accusations, saying in a statement that “carrier partners are free to decide which applications and services to include on their Android phones.” South Korean consumers are famous as early adopters, and most new phone buyers here are opting for smartphones.
