Asked and answered, that's a tidy post. I was going to suggest CM7 has the ability to change the screen colours as well, and on my Nexus One I tweaked it to have better white balance.
I honestly have not even noticed my NC WB is off, now I probably will and it'll bug me. Thanks...

thank you
I want to have a regulation color software can be.
You europeans americans may feel colour temperature just right!

If you're running CM7, change settings in "Render effect" (CM settings > Interface > Render effect). There are some calibaration profiles in there.

Lol...whats next ? Full blown ISF video calibration on our nooks !

CM settings > Interface > Render effect
This colour temperature lower.
Why not do a adjustable?

And what would you do with a light meter? Measure the brightness of the screen?
It's obviously not going to tell you the color balance.

It is useful for color calibration, but not for the contrast. So the blacks will stay the same. The whites on the other hand, can be changed.

So, is there an application to make the black more black than black?

No. The screen is a TFT LCD. The light blacks are caused by the leakage of the light behind the crystals. So there is no way to get darker blacks. That's why Amoled screens have the dark blacks. It's all about technique

The only thing you can do is to set a lower backlight level. In my impression the auto settings for backlight is not working to good, especially in low ambient light conditions. Install a third party backlight controller, like Lux Pro from the market. Then you can fin tune your backlight settings for all lighting conditions.
Black will then become more "black" due to lower backlight level in most conditions.

Loss of contrast

Anybody else who is kind of experiencing loss of contrast in the Z3+? Mine is Z3+ Dual.

The screen. Mine is sometimes losing contrast. Well, I can say it's contrast not brightness as the brightness level isn't changing.?

Yes there is a lot of white on display you'll notice especially if you have black icons on home screen

From what I have experienced, it only happens when in very bright areas, for example direct sunlight or offices. The phone boosts the image brightness in the darker areas for better visibility in bright situations. This is a kernel thingy, and I thought it could be a part of the X-Reality engine too, but "disabling" it in the settings doesn't disable the contrast change. Is this your experience, too?

As I know, it is something related to Qualcomm technology, known as Assertive Display. Maybe this can help you understand. https://www.qualcomm.com/news/snapd...ay-power-efficient-technology-thats-easy-eyes

I have experienced exactly what you described too!

It's the assertive display playing up. I disabled it at one point but reverted back as it works so well apart from these instances.

Is this normal for the Nexus 6 display?

My display is like this on white/grey backgrounds at low brightness?

No one?

No, it shouldn't look like that. RMA it if you can.

Here is an image I just took https://i.imgur.com/dqVkSGu.jpg
The two dark regions that are running down the screen.

This is a result of the AMOLED screen. All AMOLED screens will exhibit this.

Samsung decreases contrast a lot when you put the device on low brightness to counteract it. So it *technically* still does it but their software prevents it from being very noticeable.

The contrast adjustment is a software thing, not part of the display.
