功能手机, or "feature phone," is a type of mobile phone that primarily focuses on basic functions such as calling and texting. Unlike smartphones, feature phones typically have a physical keypad and a simple user interface. They often come with limited internet capabilities and basic applications, making them suitable for users who need a reliable device without the complexities of modern smartphones. These phones are popular in many regions due to their affordability and long battery life. They are especially favored by individuals who prioritize communication over advanced features, such as social media or high-resolution cameras. Brands like Nokia and Samsung have produced various models of feature phones that cater to this market.
