Is there a way to determine which vendor the screen in an iPhone 7 Plus is from? I recall reading Apple is getting panels from Sharp (now owned by Foxconn btw) and Japan Display (a joint venture between Sony, Toshiba and Hitachi). How can I tell which panel a phone is built with, from the serial or by plugging in? I never buy anything right when it comes out and prefer to wait for the issues to be sorted out. So I just got a couple of iPhone 7 Plus devices now that they have been cranking them out for a while. One had a satisfactory blueish screen (like my iPhone 6 devices) and was a keeper. The second one however went back and I am now on my 4th replacement. Insanity! But I can't settle for the garbage yellowish (warmer) color temp. All phones I have gone through were made in the Zhengzhou (Foxconn) factory. These two iPhone 7 Plus devices pictured were made in the 52nd week 2016 (left) and 1st week of 2017 (right). These two are the best ones I have received so far and in person the one on the left looks better. One of my iPhone 6 devices is on the far left set to the same brightness for comparison.
