Have any of you (Nexus 7 owners) experiences an uneven color temp/brightness across a Nexus 7 screen? I have searched threads in google but found no Nexus 7 owner mentioned about this but many iPad owners did (see thread). My Nexus 7 is a C9O which was replaced a screen by ASUS 1 week ago (due to broken screen). I have noticed this problem 2 days after received it back. My screen is generally a "warm tint" (as most N7 are, I believe) but when I see a white or grey background (in ebooks or webpages) in portrait mode, about 1/3 of the left screen has a more cooler tone and it is gradually warmer toward the right. There is hardly noticeable when I watch movie or surfing most websites but it's quite annoying when I read e-newspaper or ebooks which are around 70% of my usage. Note that this is not due to viewing angles since I tried to rotate the screen / change viewing angle and the problem is persist (on the "correct" side). I tried to use my DSLR to take a shot of my screen but it can't capture the uneven color temp just like eyes do. I just want to know if this is normal for an IPS/LCD screen? Please share your idea / experience on this. Any way to fix it? Thanks!! PS. Sorry for my bad English.
