Welcome to Android Central! The screen might have been replaced. Look around the screen glass edges--does it look pretty clean, or is there any glue-like residue?
Any way you can contact the seller and ask about the phone's repair history?
I don't believe there's an app that will tell you if a phone is refurbished. If the seller is legitimate, they would have to inform you that the phone is refurbished. And if the refurbishment was done by the manufacturer, it's supposed to come in a box that clearly states it's refurbished.
