Exchange possible. Only the display has an issue; an IPS display is installed, and there is a mark on the top due to pressure. I have been using it for 6 months without any problems. The fingerprint sensor works perfectly. It has a back-breaking sticker applied. 4/64GB, Snapdragon variant. The camera is beautiful. Only the device is provided; for security, I can provide a photocopy of my NID card, and you can get it stamped if you wish. Location: Gazipur Konabari.
