The display has been replaced with a market original OLED display. The back cover is cracked, and the volume button works but requires a little extra pressure. The SIM tray is broken, but since it stays inside, it is not noticeable. The camera is 100% functional, and you will get around 4 hours of battery backup. Exchange is possible; anyone looking for a good camera phone can take it. Send a message if you need to know anything else, thanks.
