China’s Huawei has seen its market share significantly decline due to U.S. sanctions. Instead, other Chinese companies—Xiaomi (12%), Oppo (10%), and Vivo (8%)—occupy the third to fifth positions. South Korea’s LG Electronics withdrew from the smartphone business in 2021, resulting in its market share disappearing.
While early smartphones focused intensely on boosting adoption rates through hardware price competitiveness due to their high cost, the current landscape sees phones with powerful hardware emerging as consumer demand for premium mobile devices grows. Smartphone hardware has become a key competitive factor, as evidenced by the prevalence of comparison comments in recent launch articles, such as “This phone has better RAM than the 〇〇〇 phone…” The rise in market capitalization of Qualcomm, one of the most successful companies in this hardware competition market, which manufactures and distributes smartphone CPUs, clearly demonstrates how much the hardware market has grown. Additionally, smartphone camera capabilities have emerged as a significant purchasing factor. Advances in camera technology have enabled smartphone users to easily capture high-quality photos and videos, which, coupled with the rise of social media, has become a powerful marketing point.
The smartphone operating system market is increasingly solidifying into a two-horse race between Android and iOS. As of 2024, Android holds approximately 71% market share, while iOS accounts for about 28%. Operating systems that once existed, such as Symbian OS, BlackBerry OS, Windows Phone, Samsung’s Bada, and Tizen, have essentially disappeared from the market or hold very negligible market shares. Consequently, competition in the operating system market is virtually nonexistent. The rivalry between these two systems extends beyond mere market share, intensifying fiercely in areas like user experience (UX) and ecosystem development. Android has expanded its market share by collaborating with diverse manufacturers through its open platform, while iOS has emphasized the integrated hardware and software experience to foster user loyalty. Consequently, consumers choose the operating system that best suits them, enjoying deeper experiences within each respective ecosystem.
Meanwhile, the application market continues to grow vigorously, with numerous apps released annually by both diverse companies and individual developers. Apps utilizing cutting-edge technologies like artificial intelligence, augmented reality, and virtual reality are particularly gaining attention, and this trend continues to attract sustained interest from both consumers and manufacturers. One of the greatest advantages of smartphone usage is the opportunity to access diverse software. Services enabling users to easily download various applications and software—such as games, e-books, music, and videos—have flourished since Apple’s App Store launch, forming a massive market today. The growth of the mobile gaming market is particularly noteworthy. Many people enjoy their leisure time through smartphones, and mobile games are at the center of this. Consequently, game developers are releasing games optimized for the smartphone environment, generating continuous revenue. This massive market significantly impacts society, fostering the growth of youth ventures and small-to-medium enterprises. Examples include ‘Dragon Flight’ developed by NextFloor and SundayToz’s Anipang.
The smartphone’s inherent ability to host diverse content, coupled with increased data availability through mobile network advancements, has fueled growth across multiple media markets. Easy internet connectivity has also boosted social media activity, expanding into business ventures leveraging SNS. Smartphone-based SNS services, being easier and more convenient than PC-based alternatives, have seen particularly strong growth since smartphones became widespread. SNS has transcended being a simple communication platform to play a crucial role in information sharing, dissemination, and public opinion formation. For instance, Twitter serves as a powerful tool for real-time news delivery and public discourse, while Instagram has established itself as a leading platform for visual-centric communication and marketing. The most widely used SNS platforms include ‘Facebook, Twitter, Instagram, Telegram, Zalo, and KakaoTalk’.
Smartphones have formed a symbiotic relationship with various businesses and individuals, including media companies, by providing and supplying media, thereby creating mutual benefits across diverse activities. Smartphone usage has brought numerous positive effects, such as enhancing work efficiency and significantly improving daily convenience through various applications. Furthermore, through multiple SNS platforms, it has diversified communication, enabling social interaction and the formation of new human relationships, playing a core role in the 21st-century information society.
