CM7 rom with bad image quality? (picture) - Galaxy S I9000 Q&A, Help & Troubleshooting

I am not sure if it is the general CM7 or the rom I installed based on CM7 (Cyanofortomorrow 1.2)
Every screen image I see from this rom is showing heavy gradation at
deep colors which did not appear on stock roms.
It is clearly showing less dynamic range in every image,games,videos. I am not sure if it is the CM7 general issue or the Cyanofortomorrow 1.2 issue.
Is there a fix for this?
It is not so strong on the PC screen, but it looks really bad on the phone.

Green tint when displaying white backround?

Hi. I just started playing with an SGS and am very impressed by it.
Mainly performance and beautiful, vibrant screen make the phone shine. In terms of display, it beats my Desire hands-down. But there's one thing I find odd - after flashing it with Darky's 7.5 Rom(to be fair, haven't tested with stock rom), the first time I entered the browser (with white Google start page) I felt as if I were an actor in "Matrix"
To me, it feels like the screen has a clear green tint when displaying white background.
I compared it to my Desire (to make sure it's not just my eyes), and even though its screen looks very modest compared to SGS's most of the time, it looks much "whiter" (tested on about:blank, both had max brightness, Desire is LCD model)
Unfortunately, I haven't tested it with the stock rom to see if it's software or hardware fault. My friend bought an SGS as well, and hasn't flashed it yet. Will compare to his phone.
Can't make a photo comparison - don't have a camera good enough to show such slight color tints.
Is there any objective way to test phone's color accuracy? Or to manually change the colors, like in old-school CRT monitors or TVs?

Try downloading the flashlight app that uses the screen as the light source then launch the app and check the screen. Or just input this in the keypad *#0*# and test the screen from there.
Hope it helps

[Q] Onecosmics ics colors

i have Onecosmic ics rc1 and everything works fine,but i notice that the colors aren't as bright as they should be.. is a little yellowish even when brightness at 100%.. is there a fix for that or that's the way it should be ??
Did you flashed Fugu kernel with VoodooColor or without?
I suggest you to try both, to see difference.
i flashed all of them and i dont see any difference.. ive flash the one with voodoo color and sound and the one with color only, but still the same.. i dont even get the voodoo app..
ICS with bluish low colour
Hi,
I Have the same issue, mine shows bluish low colour. i flashed both kernels with same results more so...
Model = i9000
Android Version = 4.0.3
BB = I9000UGKG3
Kernel = 3.0.8-FuguMod
any suggestions please? :|
Okay here is a little update. (Its not a complaint as i know it'll be resolved hopefully)
I flashed the Voodoo Color Kernel and there was a significant difference.
The "Yellowish" tint was gone.
But while at 0% Brightness, the screen is Darker than usual ... Its just as Dark as it is on a SpeedMod Kernel ... which is, lets just say ... NOT GOOD FOR EYES AND BATTERY.
The screen looks satisfactorily better above 0% Brightness. I have noticed that if you keep the Brightness Level in/around 10% ... you will feel the difference.
EDIT: My Apologies
Yellowish Tint is STILL THERE
It took me a while to notice it.
But this time (i mean after flashing the Voodoo Color Kernel), the Yellowish Tint was quite less than before.
However, while using the "Flash Light Utility" ... it displays a 100% WHITE, which makes me assume this Yellowish Tint has something to do with "Theming" as the Phone Itself (after flashing OneCosmic's ICS) is display the colors just fine.
well i think ill have to wait for the next onecosmic's release or kernel fix or something like that..
I haven't used Voodoo a lot, but you should download Voodoo app from market and try to figure colors with that.
I am using voodoo app but not able to see the colors option in that...
I have checked and the kernel I downloaded was the one with voodoo sound and voodoo colors..
Am I missing something?

[Q] Screen flickers, green tint, ICS.

Hi guys, I did some searching and couldn't find a fix so here goes:
Often when I put my phone to sleep (tap power-button) the screen turns black, then green again for half a second or so after the "screen off visuals".
I did some searching and it is similar to this "common issues" post:"Screen turns unusual colors / flickers colors when going to sleep or waking." http://code.google.com/p/ice-cream-sandwich-sgs/wiki/CommonIssues
The only thing is, Voodoo control app is now Voodoo sound plus and doesn't have a "Gamma offset" option anymore.
Does anyone know a tool that has Gamma Offset options, or any other fix to this issue for that matter?
It's not a big thing, as my phone is working fine, but I wanted to research it a bit further.
It has happened to me through many different ROMs, mainly ICS roms, but I am currently running ICS333 v.2.0.1 ICS 4.0.4, with the newest Devil Kernel for ICS.
*BUMP* in hope of info/help
- sorry mods if this is unacceptable.

Serious problem with AMOLED monitor of my NOTE.

Hello guys,
i'm new to the Galaxy Note and the Forum, start by thanking everyone for the great job you have done and are doing.
- Before:
I bought a Galaxy Note, I am fine and i love him like a son (maybe because I have no children).
There was the original version of Android 4.1.2 firmware N7000XXLSA with NO brand.
I flashed from the original recovery kernel that is here (forum.xda-developers.com/showthread.php?t=1901191) to be precise "Philz-cwm6-XXLSA-DBT-v3.99" (I do not know why I chose this among others, perhaps because it reminded me of the original LSA final XXLSA and makes me wonder: the "Philz-cwm6-ZCLS8-CHN-v3.99" is newer than the one I flashed?).
From ClockworkModRecovery I installed, after fullwipe, the last Nightly of CyanogenMod 10.1 and the gapps (as I did on other phones like Nexus S and Nexus 7 and it is always gone smoothly).
- The problem:
Everything works fine (apart from a phenomenon of Battery Drain, but I have to recalibrate it and recharging from consuming it all off for at least 4 hours and then delete the stats etc ...), but there is one thing wrong: the monitor.
The icons on the desktop can be seen very well, ultra bright and the text looks really HD! (I come from Nexus S and I also have the Nexus 7, bright colors and blacks amazing!) But the background, some photos appear, or the shades of black phone menus you see badly.
If I use MXPlayer to see a video all blacks are pixelated, gradients are sheared.
As if it was in safe mode, type windows xp in safe mode that NOT loaded the video card drivers.
I read around on the issue and there was talk of color banding, 16bit software compared to 24bit monitors hardware, but in essence what?
Depends on the kernel?
I have to go in customer care to replace the monitor (which also occasionally changes almost imperceptibly color, for example while navigating, then on the white background of the pages, from white light turns yellow, then brown, and so on).
What do you recommend? Does anyone have or have had the same problem?
UPDATE:
This morning I tried the phone around, the street outside and the problem seems to disappear.
I set auto brightness. So maybe with strong light, increasing the brightness of the blacks are softened better.
Now I'm recovering from the last original software Samsung Kies, the much-hyped premium suite, see what happens and if the problem remains.
Thanks in advance to all.

I recommend go back to a non leak firmware which is not buggy like this one. Then see if you can reproduce. Remember those JB roms are buggy leaks. Best to use the kernel phills made explicitly for the rom version you are running.
Regarding colour changes this usually is due to powersaving apps or settings. Remove and/or disable those. especially the one in the stock browser. This a known old issue not necessary caused by hardware.
battery drain issues van best be analysed according to ahalfords sticky on wakelocks.
