Screen Uniformity. - Samsung Galaxy A70 Guides, News, & Discussion

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.

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.

Note 5 display showing colour tints

Hi friends I wanted to know does your N5 display show colour tints while holding 180 parallel to the eye is this natural oled problem or there is problem with my diaplay

AMOLED are sometimes turn to purple or blue
LCD are turn to white or black (become dark)
:good:

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.

Pixel 4XL screen hue

Is it just me or the pixel 4XL screen has a bit of greenish-yellowish tint to it with Ambient EQ off? I'm kind of nit-picky so it's been bugging me lately.
It's a consequence of having 90hz at a lower brightness. Unless it's like that even at a higher brightness level?
Yup. I don't know why it's the 90hz cause never had this problem with my 7 pro.
I do find it is calibrated to green even in normal conditions

Interesting, since I do see multiple reports about the same problem on the 7pro and 7t regarding green tint.

I've seen 7t but when you look a lot them are not the same and they look more like hardware issues.
I've had the 7 pro since launch and have had the community app, XDA and Reddit which I look at regularly and I've never come across a thread about a green tint because of 90hz
At 100% brightness it looks fine, But if I dim it to 75% or lower, there's a little bit of green tint when you look at it on a white background.

Can you disable 90hz on the oneplus devices? If you can then maybe it just never occurred to them to try to disable 90hz and see if the issue still persists. It certainly didn't dawn on me until I saw someone else having the issue and they reported disabling 90hz solved the problem.

Not sure. But like I said the issue looks different and more hardware when you see pictures, the sort that have plagued some batches of panels for years

I tried disabling 90Hz. It does not correct the issue of the green hue. It is not as bad, but it is still there. What disabling 90Hz eliminates (mostly) is the red-shift that occasionally occurs.
It's doing my head in now. My screen has a green hue, really bad on Grey's, worse the dimmer it is. I can turn my screen off and on and instead of a green hue it's purple and super contrasty instead. Going to try a replacement but I'm not expecting it to be much difference as seeing same problems from other users.
The black crush in lower brightness seems to be worse than the op 7 pro too

Don't waste your time with a replacement i did and it's the same, Google have calibrated it like this deliberately do a search on Google. Will wait for the 5 unless they've sold even less pixels this year than last year in which case we may not a see a pixel again while that current development team is in place.

Did you also turn smooth display off as well? Since as of the Nov update it kicks into 90hz at lower brightness levels now.
Pixel 4xl has very warm display. Staying next to my note 9 looks bad. Basically no whites unless 90 plus brightness.

Yes, I did. There would not be much point in doing half a test. I’m very thorough with stuff
Hi guys I have a pixel 4 whose display shows some green spots while displaying blacks. Do you think it's burn in or it rather be the green tint that everybody talks about? Thank you very much, I don't know if I have to do a replacement or not ?
ps. if you zoom in the right corner you can see these green spots

Looks like you have some stuck pixels there in this case the green sub pixel is stuck. Could try to run a stuck pixel fixer and let it run for awhile. But honestly ,it looks like you have so many that a miracle would be required. I would just contact support and have them RMA.

Low brightness - Screen Gamma/Calibration Performance

Does anyone else feel like there's a haze/fog over the screen when the brightness is around 20% or lower?
This seems to be more noticeable on grey backgrounds. White and pure black seem perfectly fine to the eye
It's hard to try and explain?
Could it be the same issue that*plagued the 4 when it originally came out. Gamma/software calibration*needed*possibly?
It seems fairly uniform too, which makes me think gamma issue rather than panel/HW issue?
Has anyone else noticed the same?
yes, i see the same!
Yeah, we discussed a similar behavior in this thread: https://forum.xda-developers.com/pixel-5/help/colours-bit-off-everything-bit-beige-t4179867
For me I do see this "fog" brownish tint in every brightness situation....

Not the same thing. You're on about color profiles in that thread. This is more like a contrast issue at lower brightness levels
Well... than i have both... there’s fog with loss of contrast and there is a „warm“ color calibration.
My P3 shows black areas where the P5 is grey. Plus, white is minimal brownish so i loose contrast.
I come from a Pixel 2 XL with the black crush. In terms of contrast at low brightness levels, the Pixel 5 is far superior.
Undecided whether to keep it or not.
Grey's look really weird compared to my S10e. Nice and dark on the S10 and really light/pale on the Pixel?
Here's a capture of screen uniformity too
