I'd thought I'd found an acceptable iPad two weeks ago. It wasn't perfect, but considerably better than previous ones. But the more I used it, the more I noticed and was annoyed by, a big pink patch, and a greenish cyan one. I'm not sure whether these patches developed over time, or if I just didn't notice them at first. It was a DM serial.
Still, I decided to keep it, telling myself another replacement would just be worse or bad in a different way.
Then I saw this thread about the unknown DY factory. I had remembered reading elsewhere about someone who got what they considered a very good replacement that had a DY serial, and the posts in this thread seemed to concur.
Today was day 14 of my return period. I decided to try one last time for a non pink/green screen. I boxed up my current one and headed over to Apple. I told the sales girl that I had been very unlucky with these new iPads so far and that I had heard of a new crop of good ones popping up with a DY serial number.
She said flat out, "I can't search through a stack of boxes for a specific serial number, sorry". Well, screw it I figured, I'll just buy another one, like I have done before, and return the worse of the 2.
She pulled one out and began to ring me up. I peered over the counter at the back of the box. To my excitement, it was a DY. I paid for it and headed to a table to open it up and make the big comparison.
It is considerably better than my previous one, which was considerably better than the ones prior to it. Side by side, the DY is noticeably cooler and more evenly colored. No pink or green visible at any angle. It does shift to a warmer hue when tilted away from the face. No dead pixels. No foam gaps.
So far, I am finally happy. I said I didn't want to jinx the previous one by saying it was great, which it turned out not to be, so I won't say that about this one. I will be keeping a close eye on it for any color degradation, because I could swear my previous got pink/green over time. Maybe I'm wrong.
*EDIT* Just found the post I was thinking of from April 11.
Went to apple today and bought one but returned due to backlight bleed. Then bought another at the same apple store with better backlight bleed. Both iPads were NOT made by Foxcom in April (serial start with DYTHH). Both have cool white.
If you want cool blue white, get one with serial starting with DY, not Foxcom. Anyone know who is the manufacter with DY
