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, 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.

s10e screen problem?

Hello, I have a few days with my s10e but today I notice something strange thanks to xda labs app, scrolling threads on some picture profile was black so was a black circle and when I scrolling in that part the black circle, it's hard to explain with words but when the black circle moves it just moves and left a black trace like a shadow and disappear slowly until I stop scrolling, only with black objects do that, is it normal or its a faulty screen?

Perfectly normal for oled

You mean screen ghosting? Well normal in oled after 1 or more yr but if it's new then exchange it!!

That's not true, all AMOLED screens do this new or old, some less than others but if your screen is dim and you scroll with black on the screen slowly you'll see ghosting

Thanks everyone, I was thinking was a hardware related and to exchange it right away but need proof first

Colour changing
While increasing brightness slowly i mean really slowly i can see display colors changing like normal then purple again normal again purple do it slowly guys please let me know thanx.

You have to do it slowly and steadily it can be seen clearly on white picture,background or a wallpaper. Try doing it agajn at night time turn off your lights around you and check it broda letme know.

Yes you are right , having it on my new a50s .. samoled

Screen Uniformity.

So how's your screen uniformity on dark greys? Try opening the calculator app in night mode and change your brightness from 0 to 100 slowly. Do you notice any colour shifts?

Can confirm that! Weird stuff indeed..

No it's how amoled works. Some phones are better and some are worse. Samsung should've used pure blacks on their night mode knowing that amoleds cannot display dark greys properly.
