Only the display has been changed; a market-original display is installed, which has great colors. I spent 15k to install the display. Face ID and True Tone are all okay. There are no problems with the phone; if there is any problem, I will give the phone for free. It is updated to 26.5, and the camera is just awesome. I need money urgently, so I am selling it. You will get the cash memo with it! My exams are going on; if you call after the 11th, the phone might be off.
