A smartphone is distinguished from a regular mobile phone by its advanced capabilities, integrating features such as internet connectivity, a wide range of applications, and robust processing power. Smartphones typically support touchscreens, cameras, and multimedia functions, allowing users to browse the web, run apps, and access social media. Moreover, they often have operating systems like Android or iOS, which enable customization and functionality beyond voice and text communication. This makes smartphones essential tools for modern communication and daily tasks.
