Received Samsung Galaxy S21 ULTRA 512gb intact. BUT !!!!!!!!!!!! 1x camera is not focusing properly. takes blurry pics, very annoying. Seller probably knew about the defect because it's FIRST THING YOU NOTICE when you open the camera. now I lost a night importing stuff and I have to go through return/repair process.... disappointed. 900$ lost and an other week waiting for a new phone...
