Oh I totally understand, I do the same thing with my phone. I actually use my Nexus 6P at minimum brightness every evening. So I'm right there with ya.I know that is all tonuge in cheek, but with the way I personally use my phone I could be one of the people who would notice screen issues if the brightness is right down.
OLED has been around so long that I actually had an AMOLED screen in my first Android phone back in 2010. I look at the screen of my current phone (OLED), which is made by Huawei, and I wonder where did they get this screen from? It's looks terrific. Why are we still having manufacturing issues with this screen technology?
