Originally, I purchased this in November of last year on Mercari. At that time, it was unofficial, but the battery had been replaced. Reason for the issue: I dropped the device and the LCD screen cracked, so I purchased an LCD replacement kit and replaced it myself. I have confirmed that basic functions (FaceID, microphone, touch operation, screen display, vibration, etc.) are working, but because it was replaced by an amateur, I cannot guarantee future use, so I am selling it as a defective item. I am not responsible for any operational defects after purchase. Carrier purchased from: SIM-free Included items: Charging cable, box Maximum battery capacity: 100% Screen crack: None Functional defects: None
