What is the primary difference between a smartphone and a feature phone?

The primary difference between a smartphone and a feature phone lies in the functionality and software capabilities. A feature phone generally offers basic communication services, such as calling and texting, along with some limited features like a simple camera and basic apps. However, it lacks the advanced operating systems and software applications that characterize smartphones. Smartphones are designed to support a wide range of functions, including internet browsing, social media, advanced photography, and the ability to download and run a variety of applications. This broader functionality makes smartphones more versatile and capable than feature phones, which are restricted to fundamental features.
