A refurbished smartphone is a smartphone model that has been returned to the manufacturer by customers because of faults or other reasons. Sometimes these phones are those which have been used to showcase in events but not used by consumers. Manufacturers fix issues if there is any, restore it to full functioning and make it working like a new device. These phones come in market as refurbished phone and generally tagged with lower price. These devices are used but not for longer time. In many cases people buy phone and return it within a week for different reasons. There is no way to check why the phone was returned. It could be returned because buyer changed mind or it could be returned because of a flaw. These phones cannot be resold as new and hence, company sells these phones as refurbished.
