Based on my Serial Number looks like my 6 Plus was made in the F2 Zhengdou Foxconn factory. My phone appears to be flawless but I remember last year seeing posts that the F2 iPhone 5s had more reports of lower quality displays than the DN factory. From all the "post your model, etc" posts it appears most 6 Pluses were made in either F2 or F1. Curious to see where everyone's phones were produced and how the quality is.
