A smartphone refers to a cellphone that combines the functions of a regular cellphone with features of a computer.
Smartphones thus not only allow phone conversations and text messaging. They can also be used to take pictures and videos, to surf the web and play music and videos - to name just a few examples. Modern smartphones can be operated by touching the phone's screen.
Global smartphone sales have been sinking. Last year, they dropped 0.3 percent as most markets become increasingly saturated — but not India. Going against the trend, India saw a 14 percent spike in smartphone sales. Anticipating a further boom, Samsung has now opened the world's largest smartphone factory in the state of Uttar Pradesh.
