S21 ultra Samsung android smartphone

Samsung s21 ultra 256gb black . 12gb ram . Phone works perfectly. There is a slight mark on the screen. Screen glass is not broken but the pixels there are dead or at least stuck on green. Only visible sometimes . Mainly when the screen is white . Please see images. Doesn't affect the touch screen. On the metal frame around the phone there are slight marks where the paint is rubbed off. Not dented. No cracks on the screen. All cameras and speakers and everything else works perfectly. I can post at buyers expense
