I've had mine for 5 days and the serial starts with CB5

The screen is slightly warm as compared to Note 2 and other phones but nothing overwhelming. It's no where near as bad as some of the pics I have seen posted here.

Viewing angles are not so great, but I am not really bothered y this.

The only thing is I find the display to be a little dark, but I am used to the Note 2.

Blue +10

Put blue to at least +6

Put green to no more than 3

Play around with it until you get the desired screen tint you want.

Take note also when you have this activated, you will not be able to install apk files ("Install" button cannot be pressed). To install apk files, just deactivate screen adjuster then install apk files. Then activate screen adjuster again.

BH907 -> yellow

but after I use "burn your screen" app on play store for 12 hour with full brightness, now my Z1 screen is low yellow but "near red".

I will try to burn to 24hours and post a result again.
[Xperia Z1 Q&A, Help & Troubleshooting] Mioggle:
I just asked a placement last monday since the Z1 that I got had a really bad yellowish screen. Serial # started with BH904.

They just called me up right now and notified me that the new serial number would be CB512. Judging from the recent postings I really hope this one will be a good one now.

Will update if the screen does have any yellowish hue or not.

Edit:

Just got the replacement with the CB512 serial.

I "believe" it is much much better than the previous BH904 that I got. Still I still see some yellow hues in it which prompted me to install the "Filter Your Screen" app.

With it I see that the screen is much better but I still feel it is a little warm on color.

Can this this still be fixed with an update? I want to update to .534 but people are saying that trouble starts when you update to it too.

[Xperia Z1 Q&A, Help & Troubleshooting] pecholino:
i think because Z1's use different screens, those screens need different settings, so newer firmwares do tend to distort whites on certain panels and make other panels look better.

just my guess..

what if a developer could integrate older fw's panel settings to a newer firmware? or even better - to make a flashable zip for people with yellow hue problem?

well.. at least we know it's a software related problem:)

just my 2 cents.. :)
[Xperia Z1 Q&A, Help & Troubleshooting] kannanX10:
Yes that would solve this issue with latest fw....I too tried long back by flashing back to my initial. 518 fw which had a excellent screen calibration from. 257 fw which somewhat made the screen to look dull....
[Xperia Z1 Q&A, Help & Troubleshooting] X3M4:
But my older yellowish screen z1 has "the Same" JDC display that my New replaced z1, however, my New z1 has perfect White and the anoche one, no. Then, how the developers know which screens are yellow tinted and which no? The only solución that i think it's the implementation of an options on the developers menú or on screen adjusts that allow to turn on/off this "homemade solution" (i say that because we must remember that the yellow hue it's a Hardware issue and not a software issue...).
