Mobile Phone Classification

Mobile phones are divided into smart phones [2] and non-smart phones (Feature phones). Generally, the performance of smart phones is better than that of non-smart phones, but the performance of non-smart phones is more stable than that of smart phones. Most non-smart phones and smart phones use the CPU of ARM company in the UK. The main frequency of the smart phone is higher, the running speed is faster, the processing task is faster, and the daily life is more convenient (for example, the main frequency of the Nokia N81 is 369 MHz); The main frequency of non-smart phones is relatively low and the operation speed is relatively slow (for example, the main frequency of Nokia 5000 is 50 MHz).

Smart phone, like personal computer, has independent operating system. Most of them are large-screen computers, and are capacitive touch screens. Some are resistive touch screens, which are powerful and practical. Users can install programs provided by third-party service providers such as games by themselves, which can continuously expand the functions of mobile phones and realize wireless network access through mobile communication networks. In a broad sense, smart phones not only have the call function of mobile phones, but also have most of the functions of PDA, especially personal information management and browser and e-mail functions based on wireless data communication. Smart phones provide users with sufficient screen size and bandwidth, which is convenient to carry around, and also provides a broad stage for software operation and content services.
