I purchased my MBPr when it first came out (15"; Mid 2012), and just a week ago I noticed a dead pixel developing on my Samsung screen. So then I took it in the first time and the Genius said that it was a hole in my screen; thus, it was my fault and does not go under manufacture defect (MD) warranty. I was dissatisfied with the diagnosis and decided to take it to another apple store and finally they understood that it was in fact a MD and got the screen replaced and back in my hands the next day. I examined the new screen, but not so carefully (in public) and thought that it was a good screen; the new screen came in as another Samsung... happy!, but when I got home I took my time and carefully examined the screen and saw 3 chipped marks on the corner of the newly replaced screen. I called the store and was transferred to the manager, she told me to bring it in the next day and so I did. They allocated a new screen for my replacement. The new screen was another Samsung, but this time it passed my initially screening for defects. When I got home I compared it to my girlfriends MBPr 13" and it seemed to be completely off-colored. The entire screen was Yellow-hued even with a screen recalibration... So then I called Apple Care (AC) and they had me go through some procedures to try and fix it over the phone, and it did not work. Now I have another appointment to go in on Monday and have it looked at and get it fixed.... Overall, I think apple needs to have better quality control over their entire line of products from Asia... I understand that there is a huge pressure and a big market to make money, but I am just waisting my time going in and out of the apple store to get justice for what I paid for the machine. I am a college student and I don't have the time for this quality control and MD to put me through all this hassle. Ps. Another defect I noticed is it consistently makes a creaking noise everytime i picked up and hold my laptop from the bottom.
