How to adjust gamma - Xperia Z1 Q&A, Help & Troubleshooting

Got my spanking new white Z1 downunder australia today. Lucky to get a nice non color tinted screen. Only thing is the gamma seems a tad too high especially the top of the screen, the LED backlighting seems to come from there. Even with a black picture there is some whitish brightness to it.
otherwise videos are very vivid in color. Viewing from the side is the usual slightly washed out coloration as in other sony panels from what i read.
any apps to tune down the gamma or just wait till next official firmware fix??

[Q] Screen getting dark; blue tint and marks behind display

My Captivate's screen has suddenly gotten much darker than usual. Even at low brightness, the image quality used to be really good and the screen was really sharp. Now, for some reason, it seems to have gotten noticeably darker and duller. Aside from that, the whites seem to be tinted blue. I know this is an existing issue with the Super-AMOLED's so I'm not too worried -- I'm thinking it was probably always tinted and I'm only noticing it now that I'm really looking. The last thing I noticed about the display is a set of odd marks behind the screen; oval-shaped markings slightly to the right of center running from top to bottom and left to right. Anyone know what these are?
Assuming you haven't flashed a kernel with the brightness fix, color fix, etc. you can get the phone exchanged through warranty for display problems. One of ours developed an issue with the tint and clarity and we had it replaced no problem.

Let me clear up the Yellow Hue problem.

I'm not an expert, my conclusion is based on my time spent with my old Z1 ( defective screen, Sony service center agreed as well ) and my new Z1.
So here goes:
I bought a Sony Xperia Z1 C6902 around the end of last month. After coming home I almost immediately felt like there was something wrong with the screen.The display light seemed to be coming from the sides ( like underwater divers with lights).I had this yellow hue and slight tilts would produce drastic washing out + more of this mysterious "yellow hue" everyone's been talking about.The display just didn't seem uniform. Videos and pictures however seemed to display perfectly. A completely white screen would appear patchy.
After a lot of running around, going nuts and tweeting, I finally got my replacement Z1 today.
Now : Slight tilts DO NOT produce drastic washing out anymore.The screen displays uniformly now .The sharpness of viewing angles still sucks, and there is slight washing out, but only after you're holding it at an awkward angle.
HOW TO CHECK IF YOUR Z1 displays whites correctly.
Do this : Go to your service menu. In your device, open the dialer and enter *#*#7378423#*#* to access the service menu.
Hit Service Tests ---> Display
You will notice the 1st and 2nd screens match the yellow/off whitish tone of the settings menus. ( On a bad screen it will be patchy, on a good screen it will be uniform )
Now tap the screen 8 times
THIS screen will show you if your device displays whites correctly.
(attached pics of my replaced Z1's display test from the service menu )
Conclusion.
There are 2 things going on here.The yellow hue and and bad Z1 screens are two different issues, but not completely separate.
The yellow hue /off whitish color seems to be Sony's color config for the Z1.( check the screen i've mentioned above to know if your device shows whites correctly )
The bad screens are the ones that don't display uniformly and seem patchy ,have drastic washing out on slight tilting ( which in turn, seems to make the "yellow hue" seem worse, making people think they're connected.)
So,
Bad Screen : Patchy when displaying a full white screen, drastically bad viewing angles, not uniform, display distortion on even a slight tilt.
Good Screen : Decent viewing angles, NOT patchy when displaying a full white screen, uniform display.
ALL screens seem "yellow".
Sony's customer service here was SO SLOW and It should have happened sooner but after almost a month, I'm finally using the device I paid for.
Trust your eyes. Don't blindly accept that all Z1 screens are bad. The Z1 has a lovely display.Know the difference between the "yellow hue" and a defective screen.
Best of luck !
When you say patchy are you referring to like uniform patterns squares (pixelated within)? I see these pixelated squares for all colors in the screen calibration and the 2nd color was like very light patchy horizontal bars. I thought it was my thumbprints but no. I cleaned the screen before the test.

Nope, that's not what I mean. When I say patchy I mean a non uniform like display. Almost looks like there's light patches of water on the screen.

2 issues i have noticed so far. Display,Slow motion.

Yesterday i got a mi 8 6/128 and i found for now 2 issues till now the first one is that when i want to take slow motion video it flickers a red light like hell, the second one is the screen itself when holding the phone and looking at it straight in front the color of the screen seems a bit yellowish also the colors are a bit under saturated when i see the screen from a side view even from bottom or from any side the colors pops out and the white backround is white as it should be i think it has something to do with the front glass that covers the panel and i don't know if there is a way to fix that, i use cool color reproduction on settings but it still annoys me.

the same here with yellowthint
i remember from op1 it was the glue they used
so maybe the same problem with mi8
or they use the same type of display like oneplus didt in op1

Poor Screen Colors

I just got this phone and I am really disappointed with the colors on the screen. Everything looks washed out and dull. I have tried the color calibration and it still doesn't help. My screen looks nothing like the screenshots here, nor any of reviews I have seen. Any help or suggestions? I'm not looking for oversaturated colors or for the screen to be on par with higher end phones. I just want it to be better.
Orange colors appear more of a burnt sienna color and fair skin people almost have a bad spray tan look.
Colors are totally fine on my device. Yours may be defective.
Try increase contrast. Worked for me
I reset the device and the display is a lot better.

I also have the same issue with my screen, calibration is inconsitent and fluctuate between some orange tint, if I adapt it it slowly drift to get orange again. When I set all RGB values to 100 % it's more like a greenish tint that still drifts to orange.
I don't understand what's going on with my screen...
HEy guys...I`ve found it
Go to accessibility and search for color correction something like that and turn it off

Question Display stripes/grain?

Hey,
Just bought this phone used and I'm noticing slight imbalances on the screen, especially in solid colors.
It seems like subtle dark stripes from top to bottom every mm or so
Also their is a "grain" to the display in some colors.
When changing the refresh th this becomes more noticeable and 90hz appears to be much cooler in color.
Anybody else noticed such irregularities?
I'm not really disturbed by it, just curious if this is normal for a "flagship" screen
