Feature phone (known in popular culture as a dumbphone) is a term typically used to describe a class of mobile phones that are still technically otherwise smartphones, besides their lack of highly advanced hardware and capabilities of modern ones. Feature phones tend to use an embedded operating system with a small and simple graphical user interface. Unlike large and complex general-purpose mobile operating systems like Android or iOS, feature phones typically provide voice calling and text messaging functionality as well as basic multimedia and Internet capabilities and other services offered by the user's wireless service provider. Feature phones have a backlit LCD screen and micro USB port and have a physical keyboard, a microphone, SD card slot, a rear-facing camera to record video and capture pictures; and GPS. Some feature phones include a rudimentary app store that include basic software such as mobile games, calendar and calculator programs.
