Hi, i just received my new Mi 11i, i did some testing and i discovered that all the upper part of the screen is brighter, especially on low brightness. Is this an hardware problem or can be fixed via software? Am i the only one experiencing this?
To check, set "Color settings on original", refresh rate on 120hz (at 60hz the screen seems better) and set brightness on low. Then open any app with grey background (like chrome).
NOTE: I already asked for replacement once, this is the second phone with the same problem (so maybe it is a software issue? Or maybe i'm only unlucky)

hes not unlucky, its basically common for amoled panel, but some people never realise that they have exactly same green tint on their own phone bcs setup of phone need to be on specific scenario, lowest brightness, dc dimming (if phone have it), hz, display colour mode on enchased, also viewer need to be in completely dark room and in background of phone need to be specific colour similar to google play store colour in dark mode then grint tint is visible. This is completely normal for amoled and it can be reduced by software updates. but not completely fixed.

not common amoled , xiaomi is the most brand that affected this tint harware issue ,i have been used most of xiaomi's recent amoled phone,all of them got this green tint,it just a matter of how visible the tint scale are.
maybe because of cost cutting quality.

I don't think its a cost cutting quality, xiaomi doesn't manufacture amoled.
Also green tint is on iphone, samsung, one plus...

All of sudden the contrast on my screen increased to ridiculous amount. I'm getting color banding, even the sign on power on screen is not sharp but has some extra grayish squares around the white letters.
Everything was fine, and after one charging cycle the phone lit up to inform me charging was done and the contrast (and brightness) was all the way up with no way of changing it back.
The 'Auto adjust screen power' option doesn't do anything for me now. Was on stock 2.3.4 KG2 when this happened
I've tried restart, removing battery, factory reset, even reflash (back to 2.3.3 stock, and now I'm on 2.3.4 KG 3stock), nothing works.
Here is screenshot from phone

And here is photo of the same screen (photo quality is horrible, but it should give you idea)
Is there any way how to fix this or do I need to RMA my phone
Where is photo?
Make sure that you are not placing it under some light source which is causing the Auto Brightness to take effect, and also can't you decrease brightness from settings?

The colors and brightness are way off even on manual brightness settings. When I purchased the set and set minimum brightness it was almost unreadable on direct sunlight. Now even with lowest brightness the display is readable without any issues on direct sunlight.
Goto display and set the screen mode to Normal instead of Dynamic.

Don't have Normal there, only Standard, and it was already set on Standard.
Edit: It's not clearly visible on the photo, but the upper part (that's supposed to be full black) is covered with green dots on the display.
I've just experienced this last night, I was comparing the image I saw on my monitor to the SAMOLED and I noticed that the hair color was a very strong orange/red on my phone and its chestnut brown on the screen.. I checked the color mode and its standard.. I was playing around with the phone including rebooting it and it seemed to have gone away.
This was on XXKG6.
h4rr0d, this really looks like a hardware fault to me. Sorry to say, but I advice you to contact Samsung assistance.
Thanks for the replies guys, I've already RMA'd the cell, waiting for the service to respond now.
EDIT: Ok, so I've got the phone back today, the RMA report states they have 'exchanged an electric component', so no clue what it was. But I'm happy I've got my phone back fixed and they actually fixed it without any issues.
I've had a problem for quite some time where Google Maps on my OnePlus One displays the normal Map view in near-zero contrast (no matter the screen brightness). You simply cannot tell, looking at the screen with the human eye, the difference between roads and not-roads. In Satellite view it's fine (but of course uses much more data, memory, CPU, etc, and Satellite view is much busier on the screen, so that's not a long-term acceptable solution).
I'm running CM13 on my OnePlus One; there is no Contrast setting. (In Accessibility there are a couple of related ones, but they don't actually control contrast, and they don't solve this problem, and they're both marked experimental - may impact performance).
I found an app, Netman "Screen Adjuster", which works perfectly .. but has to be always running to hold the contrast adjusted, leaves a post in notifications (despite its option to not do so), is ad supported, etc - simply should not be necessary.
Why isn't there/ how can we add/ who do we beg/pay to add a Contrast adjustment to the normal Settings in CyanogenMod 13 ?
thanks!
Content of my post from CyanogenMod forums:
On my OnePlus One running CM13 [nightlies] - I'm not sure if this specifically started with my upgrade some months ago to CM13, or if it was this way on CM12 before also - the contrast in Google Maps is much too low. Basically it's impossible to see the difference between road and not-road in the normal Map view. If I switch it to Satellite view then everything displays fine. On some other forums I've seen similar complaints both from OnePlus users and from users of some other platforms. So it's a maps+contrast thing, not exactly specific to this model.
I've attached two screenshots and a camera photograph of the same Google Maps display:
One screenshot is of normal Map view, which viewed here displays perfectly, so it's not the actual graphic content, but how the OPO screen displays it.
The other screenshot is of Satellite view, which viewed here and with human eyeballs on the OPO's screen is fine.
The photograph is of normal Map view (I tested both with the screen brightness quite high and the also quite low, both show near zero contrast making the map view unusable to the human eye, so I'm only posting one photo here).
My guess is that either contrast or something about the graphics drivers for the OPO in CM13 are causing the valid underlying graphic bits to be displayed in very low contrast.
I'm not sure why I don't notice this in other programs, just in Google Maps.
Hm. It's definitely the OPO's Contrast setting. I found an app (which I don't like as it has to be always running to keep the contrast set properly) "Screen Adjuster" by "Netman" which makes Google Maps perfectly readable by setting Contrast to "-100" (exactly halfway between the default 0 and the maximum).
So, without using some dodgy app, how to control Contrast on OPO or more generally in CM13?
thank you.

Photo of Satellite view - looks fine
Screenshot of Map view (exactly the same thing in the first photograph) - displays fine on YOUR screen which has proper contrast, just not on a (my?) OPO:
Try to change the color temperature. It might do the trick. Settings>Screen>Color temperature
Now, that's interesting.
On my OPO with CM13 within Settings -> Display & lights -> LIVEDISPLAY, I had Display mode set to Outdoor (which seems to boost display brightness and whiteness, though in no place does it speak of contrast).
It has Color Temperature (which did indeed help .. at the expense of some need-to-get-used-to-that color variations; I've re-set those to the defaults of 6500K day and 4800K night), color calibration (100% for each of R/G/B, and changing that is definitely not what I was looking for ), Power consumption (no effect) and Enhance colors (no effect).
So while color temperature makes a difference it doesn't seem to be the ideal... but I played with Display mode, switching it from Outdoor to Automatic, and instantly Google Maps became readable.
This is in my home office, which is presently lit by subdued outside lighting on a clear sunny day. I need to go outside and stand in full direct sunlight to see if Automatic goes to Outdoor and again washes out Google Maps displays to zero-contrast unreadability.
It still seems weird that Contrast is controllable (witness "Screen Adjuster" and several others) but there is no Contrast control in Settings.
Many thanks!
Im glad that helped
There is a new feature in the newest firmware (9.1.0.178 or .177) called "Flicker reduction". If this option is enabled the control method of the backlight changes from PWM dimming to DC (-like) dimming which helps to reduce screen flickering. Under the option there is following note: "Reduce flickering on the screen. This will affect color balance and auto-brightness control".
Today I have done some measurements to find out if there is a real difference in color reproduction, screen brightness, etc. between the two modes.
Device under test:
- P30 PRO 6/128 GB (VOG-L29), firmware 9.1.0.178 C431
- Notes: battery at around 35-38%, no screen protector (and cleaned screen)
Tools:
- X-Rite ColorMunki Display colorimeter
- Color HCFR 3.4.0 software (OLED profile) for measurement (PC side)
- Voodoo Screen Test Patterns V3.4 app installed on the phone (for the different color patterns)
Measurement method:
- HCFR patterns: primary + secondary colors (fast) and grayscale
- The different color patterns were selected/switched by hand on the phone (this can cause some error in the measurements)
- EMUI color profiles: vibrant/warm and vibrant/default
- (The measurements were performed in ambient light)
Results:
Luminance, white point, color accuracy:

Grayscale:
Color gamut:
There are only small differences in the screen's color gamut using different dimming methods and brightness levels.
To sum up, the color gamut of the screen is nearly equal to the DCI-P3 color space (covers the sRGB color space in 100%) using the "vibrant" color mode. (in case of the "normal" mode the screen's color gamut is equal to the sRGB color space, but these measurements are not part of this test...)
For details (CIE diagrams), please see attachments.
Flickering:
If I look at the screen I can't identify which mode is currently activated, there is mainly no difference.....but if I look at the screen through a camera the difference is visible and noticeable. In case of the PWM control the screen flickers in the whole brightness range, while using DC (-like) dimming the flickering is less significant and is only visible using lower brightness settings (typically ~<25%)
Summary:
It can be clearly seen, that the vibrant/warm preset produces much better results in terms of color/grayscale accuracy (using both settings).
The DC (-like) dimming reduces screen flickering while there is no significant difference in the visual experience compared to the PWM control.
Very nice work. I forwarded this to our Display Analyst to see if he has any comments.

Thank you very much!
Small update:
Added CIE diagrams and a short summary about my findings on the screen's color gamut to the OP.
Congrats for your analysis. I had the same doubt. Tks
What about battery consumption, which is better among the 2 methods?
This needs to be more visible! Thank you!
Hello,
New user of this phone, the camera viewfinder goes black in dark scenes check the screenshot and the shot taken. Shots come out okay but cannot compose. Can anyone check?

I have tried both google camera and stock miui one, does the same thing in both. I still have some days left to exchange it, is there a fix or should I go the exchange route?
Thanks in advance.
Which rom are you using
couldn't this be just normal behaviour? it seem's like you're trying to make a picture in an almost completely dark room, just some low light LEDs.
live view doesn't get enough light to show you anything brighter. the final shot is taken with night mode and i bet it makes a long exposure time over 1 second+ and high ISO.
live view = multiple frames per second, it can't get as many light as the final shot with 1sec exposure.
though, I'm just guessing.
one more hint:
at the bottom of the live view screen, select "more" and then "night". it will show you live view with high ISO
in your case it's probably the same as "night sight" at the bottom left, just select it.

My note 3 pro showed proper exposure at this light but this can't, so I'm thinking there might be something wrong with the sensor.

@rayulove69 in the too dark picture you posted above you have NOT activated "night sight" or "night", just do that and see if it works.
you have actively selected "camera" and this is not supposed to give you the same brightness as "night sight" or "night" mode in live view.

doing so does the same thing and the darking is arbitrary ar also blurs the **** out of those dark parts
It's there any way to lessen the saturation of the picture without having to go into pro mode. Most of the colors in the photo are okay but the reds almost glow. I've never minded Samsung saturation but this is a bit much. Just not sure what settings that I could change to adjust this. Below I've attached S23U vs Pixel 7 pro. Pixel is more realistic.

Post processing red channel contrast curve edit on a color calibrated monitor.
Yeah that's a pain.
Your display may be part of the problem. Set display to "natural" setting. The vivid setting will cause this. Regardless if it's cam or the display calibration is sort in the air.
Oh dang. I take this back. The pictures looked more vivid because I was viewing it in the sun. Coming back inside, the pictures look more how I like it.
Yeah try to avoid using in direct sunlight as it's hard on the display. In sunlight the vivid setting may help reduce washout. Don't know if it auto toggles that on for bright viewing conditions for that model or not. Sort of looks like it does...
Turning off scene optimization in camera settings will help some. You can also change the saturation after the fact with an image editor. Google photos has that built in. Also turn on raw+jpeg in pro mode and use pro mode for high value shots.

Still after looking these pictures via PC screen i can say that first picture is too much saturated than second picture.

You're right. It's slightly more saturated than I would like but it's better than what I was seeing in the direct sunlight.
Saturation of most scenes is on the aggressive side, but the sky on a sunny day is ATROCIOUS. The blue is way way way too saturated and dark, and very difficult to correct in post.
The only way I have found to fix saturation via a permanent setting is in pro mode.Click the icon in the upper write of the screen, adjust saturation (-5 works well IMO), tweak other things (I brought up the shadows to +8, highlights down to -5, contrast down to -3). Then go to settings and under "Settings to remember" make sure that mode and filters are selected. You will have to always shoot in Pro mode for this to have effect, I think. Alas a saturation adjustment is not available in regular mode.
BTW I tried gcam with allegedly "natural processes xml" and it was the same fugly blue sky.
