iPhone mobile

Hello, I received a new mobile phone and I am selling this phone because I need the money. The phone is new, used only once, and it's clean with no damage except for a white line. Behind the white line, letters like mim, noon, kha, ha, waw, and alif maqsura are visible, but it's not limited to letters; I can see anything behind it. Also, there are light scratches on all four edges; please check the picture.
