If they put a little quality control into their products they wouldn’t have to deal with exchanges. I’m sure the cost of the general public not noticing the terrible screens out weighs the returns.
I have found the best way to show uneven tint is to take a picture of an all black screen in a dark room. It megnifies the issue so you can really see where the screen is uneven.
Here are my last 3 phones. This is what I am seeing in real world settings, obviously more faintly on a white screen. Phone 1 and 3 haave a red tint on the left side. Note phone 3 I put the protective film back on cause I was sending back. Phone 2 was the worst in all regards with a different tint in all 4 corners. It also had sort of dark lines along he edge on a white screen as well and had bad backlight bleed at the bottom that shows up.
Here is my wife’s SE. it’s much better than all of the 8+ imo. I would take that screen all day.
Here is my MacBook Pro Retina from this thread. After a while i stopped focusing on the issue I did not notice it anymore. I am hoping this is the same case with the phone. I can’t keep making exchanges for the 1 in a million shot I get a good one. I’m am going to stick with the phone in the first picture
