[REQ] App to tweak Saturation in SGS2

Hello to all!!.. is possible to find an application to tweak the saturation of the SGS2 screen!!?... it has the worst color rendition I saw in a cellular screen, I work in photography I can not even show the pictures in my telephone!!... I like this phone but with the screen of the iphone, miles away better.
Best regards!

Thanks for your feedback, the only problem is the Saturation slider, it does not work on my SGS2 and that slider is the most important
Besides that, that application is not done in good way, the RGB sliders has to modify de levels of color not the levels of brightness as the application do.
Moving all the sliders to the left has to decrease saturation not brightness as it does in a wrong way.
Regards!

I`m disappointed too with the screen colours.If I take a picture of white walls it seems to have a white-green colour.In my old HTC HD2 with HyperDroid-CM7-2.3.7,the white was brilliant white.If I put the same picture that I taked with the HTC in my SGSII,the white looks a lot greener.Is there a fix for that problem?

The colors of SGS2 are pure crap, I dont understand why there are lot of people interested in develop a firmware but they forget this part that is really important, you pay lot of money for a phone that gives you crap colors, totally biased and has no possibility to calibrate them.

Totally agree...My old HD2 with 5MP camera takes a lot better photos than SGSII.The problem is RGB calibration of the screen,not the camera.

Yes, I refer to the color rendition of the screen.

+1 for this... couldn't find any screen tuner/gamma adjuster/saturation adjuster or whatsoever for i9100 that work in ICS...
And my screen is way too blueish... and color is washed....

The gamma should not be modified, if some app is modifying the gamma is doing the wrong thing, it should modify RGB values or saturation remaining the brightness constant.

Hmmm, i thought it was gamma thing also... since I hate the blueish tint... I prefer warmer color.... >,<

What you are looking for is the Kelvin temperature to change, changing the gamma curve will change the behavior of brightness and color and that is not the way.
The controls that should have the telephone are real RGB controls without modifying the brightness, Temperature and Saturation, even better Contrast (but it should not change the colors), with that controls you could calibrate the screen the way best fit to you.

Maybe that's the control that included in CM9...

Z1C LED notification light very low

Hi to all, I have a little problem with my Z1C, the led notification light is very low, I compared the phone with other Z1C and the difference is really visible.
Is there any solution or possibility to edit to increase the power of the light
Thank's

Hey!
You can try with apps like Light Flow.
They have settings to adjust the brightness of the LED.
This however only works if its really a software issue. If the problem is a broken LED then it is a warranty issue.

Hello and thank you for your reply, I tried the application, but I can only change the colors and the speed of the flashing
The light is always low

If you phone is rooted, you can install gravity box and it has an option to set notification led frequency (by default it's 6000ms)

Thanks for the tip, now I try to hear the support from sony, if they can replace the LED under warranty, otherwise i will try your solution.
This would be the best solution http://forum.xda-developers.com/showthread.php?t=2212944 but I think it's not made for kitkat..

you do not care the frequency, but I saw that the program can handle the intensity of the LED ... all the answers are welcome and I discovered a new program:good::good:

GravityBox? I don't see such an option, only on/off duration can be set.

[Q] Color temperature

What's your lcd display?
1) dial *#*#64663#*#*
2) Version Information
3) Check under "TP:"
Mine is EBBG
Also, is there a way to adjust color temperature? I wish we had the color temperature settings for warm or cool displays

EBBG, too.
I like having on the night light mode all the time. I don't like the blue color all phones have.

Same here and I also think it's a little bit cold. But having night mode on all the time? Way too warm for me....

I had this also and my colors here is somehow slightly warm compared to my xperia z lcd

You can set the intensity. It's better for your eyes (or that's what they say). And you get used to it in a few hours But it's personal preference.

How to set intensity?

Just go to settings/display/night light. There is a slider there.
I also placed a shortcut in the quick tiles so I can turn it off if I want to and get to the slider.

If you get root and Kernel Adiutor, (maybe necessary to flash new kernel), you can set through kernel native RGB, saturation options, etc. It's called KCAL color calibration. There are posts at xda with even different profiles (think like 'how to turn lcd into amoled'). I don't have the A2, but since reviews complain about blue tint and lack of display calibration as in MIUI I thought this could be the solution for AO.

I also complain from this ****, I compred color temperature to my friend's phone (with miui)
And I found a huge difference in color temperature!!

Auto Color and Sharpness based on enrivonment luminosity

So, I noticed the screen changes its colors and text sharpness based on the environment clarity. Altough this seems a nice feature for using the phone on sunny days, the effect brings a strange oversharpened effect on the screen text. Not really a big deal, but I don't like it much.
Is there a way we can disable this feature? I've already tried going into "Settings > Display > Contrast & colors" and changing to "Standard", which should keep the contrast constant, but it seems the option isn't really working. I've restarted the phone and it keeps changing the colors and sharpness.
I made a video for you to understand what I'm talking about.

Thats samsung super amoled boosting brightness nits to increase readability,and its normal, it does happen in all super amoled screens including samsung note 8 and etc.
So it cannot be disabled as far as i know its in firmware of display.
But when you are in direct sunlight i think sharpness or color dissortion is not much of a sacrifice to increase readability.
Would it be better if you wouldnt be able to read whats on display ? dont think so.

For a second i thought my display was faulty but then realized its only for better readability. Not that I particularly like this but the sacrifice is worth it. For now haven't seen a toggle for it yet, but I hope xiaomi gives it in the next update.

Are you sure it is a feature of the display itself? Cause the brightness remain constant, what changes are the colors (contrast actually) and the sharpness...
And yea, like I said, it isn't a big of an issue, I just wanted to have control over it, but I can live with it haha.

I had this on my Galaxy S9+ and somewhat annoying under sunlight, though not as noticeable as on Mi 9 SE because of higher resolution and DPI. The only way to deal with it on my S9+ is turn off auto brightness and slide the brightness down to a manageable/readeable level.

Well my auto brightness on the mi 9 se is already turned off, and this keeps happening, so its actually unrelated to the brightness, more like a separate feature.

Have you tried disabling auto-contrast feature? It helped me.

Question App to reduce display color saturation

Hello,
Is there an app to reduce display color saturation of the fold 3 to one's liking ?

Set from vivid to natural, if you have that option in display settings.

I have done that but I would like to fine tune saturation.
I find natural saturation setting a little too agressivily low and vivid way too saturated

Natural is as close as you can get it.

I totally agree that the default is over-saturated and the natural setting is washed out. You can use ADB to get hidden display modes, which may be more to your liking.
I use AMOLED photo.

Interesting.
As I understand it the phone uses the correct ICC profile for what you're viewing.
The human eye is notoriously inaccurate when it comes to display calibration especially gamma correction.
I've tested cam to display throughput on the N10+, it's dead on. I run it in natural setting.
If I need more saturation I use some Provigil

As you infer, colour interpretation is very subjective.
So, to this end, using the ADB or other profiles is perfectly legitimate to tailor to an individual's needs. Irrespective of scientific measurements.

Actually what I'm saying is even the people who's color perception is in the top 10% can't dial in color correction by eye.
The other 90% don't have a chance.
If the device isn't factory calibrated correctly or if the display is defective these additional profiles aren't going to correct the issue.
It's nonetheless a cool hidden setting that may be useful. Unfortunately it's not easy accessible for shifting on the fly. Setting the display to anything other than natural will likely end up being an eye sore.
