Read the post carefully. The phone's display has been changed, but an original display from another phone has been installed. The ear speaker of the phone has a slight issue, and there is a touch crack in the corner. The phone's battery has been changed, but a high-capacity battery is installed which gives a charge backup of 8 to 10 hours. Face ID, True Tone, and everything else is working fine with no other problems. iPhone 11 Pro Max 4+64.016XXXXXXXX
