[APP/EXPERIMENT] Yellow tint test

Ok so I just wanted some1 to test something for me. I want to know if the yellow tint can be cancelled with a gradient overlay. So done an little app to test this.
Need some1 who has this yellow tint really bad and can see it very easily.
Again this is just a test and may amount to nothing, I need volunteers as I don't have this defect enough to see it accurately at 20% brightness.
The app is safe as there is no burn in mode yet. Just the ability to custom create a 3 point gradient from left to right with variable pixel widths for each segment.
So if anyone can test that has this really bad, that would be great.
IMPORTANT:
This little app has no burn in method yet so completely safe.
THIS IS NOT A THREAD TO ***** OR COMPLAIN AT SAMSUNG!!!
All I want to know is does this cancelling gradient help.
Start, Mid, End buttons set the settings panel to control the points (LEFT to RIGHT)
P = position
R = red
G = green
B = blue
A = alpha
So if you have a yellow tint, then you want to start with blue and alpha etc!
Updated the app to default all 3 points to 119,119,119 a 255 so the starting points are the same col as the bg
UPDATED

Not ment to be that user friendly at the moment
If it does actually do something, then I will probably have nice sliders and ability to save setting etc. Just cant be arsed doing that if it's a none starter.

Mine has the yellow tint on the left side but I'm having trouble figuring out how to use this app. It does seem to be changing gradients.

I should have made the gradients to default to gray, will alter and put new version up later today, may do a little vid on how to use also

Cool app. Seems to help if you tweak it right. What exactly does the "BURN" button do?

Well, if some1 can manage to do an inverse gradient to their yellow tint, then I would enable saving in the app, and enable burn-in, that does just that, full brightness pixel values for extended periods of time to tint the display inversely to the yellow tint, thus attempting to lessen the effect.
Ideally I want some1 with a bad example tint who also has no way to return their phone to try it

Color Calibration. Before / after

Just to share this with you guys..
With every display that I use, I try to have it calibrated and I was trilled that with the nexus I had so much control over the screen!! Never had a phone with so much control
You have here my results.
Just be aware that the "before" is with trinity kernel stock color scheme and I'm really grateful that his market tool and not to forget franco.kernel tool too,made possible for me to calibrate...
I used a 18% gray card to make sure white balance was spot on when converting the raw files into smaller jpg.
I did find that sometimes the changes did not apply so I did a double check by exaggerating the values when making the changes. Contrast was one of them..
On the graphs, the white dotted line is the reference
Only problem with this is that not all screens are the same so these settings will not work for everybody
My calibrated values
tint
red 200
green 169
blue 178
gamma
red 2
green 0
blue 0
disable dynamic contrast
contrast value 0
If you use franco.kernel tool
gamma 1.0
If you like image with more contrast, i would set it between -6 to -10

Very interesting and the before/after photos look good. Is there a problem with burn in?

Looks a little red for me. Your results look great though.

The improvement in the color of the dog photo is drastic. Trinity kernel does come with the blue really cranked up for some reason. Looking good now.

for whatever reason trinity seems to be giving me better screen color, but im sure I could do the same with franco, anyways, my gamma settings are untouched, I found that modifying the color to these values makes the purple tint go away for me:
Red:135
Green:135
Blue:190
Trinity Contrast -15 to -25

If you look at the calibrated rgb graph, red is a few points bellow reference. And again if you look at the color temperature line it is a little above 6500k. It is normal for first reaction about red when actually your missing blue because almost every screen you are used too has to much blue on it..yet again there's the tint problem on a bunch of nexus too.. if I get my hands on one of them I'll post here the results
Edit: for you "red guys" try to invert the red with blue values
Red 178
Blue 200
BUT keep gamma the same.

Thanks for sharing this. I can never get the color settings right. This helps immensely.

you're welcome.

Outstanding. I was wondering if using my colorometer would work on the phone. Looks like I have a nice project for this weekend I need to revalidate my HT and PC too so might as well throw the phone in there too :O

Use hcfr and the color swatch app from the Market..
If you get stuck on gamma, don't sweat it too much.. I spent an hour trying to get it right, no luck with this screen. Colors are bang on though.
For those who don't know, 6500k is the reference color temperature. To most people it looks too red or even yellow, but it's what the whole publishing and photography world uses.

or you can install mxplayer,
get from here:
http://www.avsforum.com/t/948496/avs-hd-709-blu-ray-mp4-calibration
the mp4 version, extract it, goto to:
ColorHCFR Fields folder,
10% Grayscale folder
and use that files with mxplayer.
My gamma is 99% spot on. I go for 2.3x since with amoled screen the black mml is almost zero, you will not sacrifice shadow content and have a great contrast

I don't get it, how you use hcfr with android? I tried but I just can test my monitor (pc) =/ is there a guide or something?
the way I do right now is testing with http://www.lagom.nl/lcd-test/ and setting manually parameters on phone until it looks great.

you don't !! you use a laptop with the colorimeter connected to it.
your phone just plays the mp4 for calibrating your screen.

Yup, just like you use it to calibrate your HT screen. I run a long usb cable to my PC and use a DVD I burned with an ISO of test screens.
Thanks for the tips on test screens for the phone. saves me the time searching them out

I was searching on web I found that I need a meter, for that is the usb port right? (like spyder2 or EyeOne) mmm I was conecting my phone XD first time trying this tools. Now I understand what all this is about.
That looks that I will be doing this as usual =/ with my only 2 eyes :cyclops: meter XDD ohh wait that's just one of them xDD
well thanks for answer and that pic looks great. Right now I'm on CM10 and config my screen with their "advance" tool and comparing to the webpage I shared. That looks good too but I perceive a little bit reddish on dark colors. Thats so F******* better than blue one XD now looks like Super Amoled plus the contrast is pretty similar to SGS3.

Great post, thank you!

Excellent information, thanks!

Hey im still noobish about quite a few things and im wanting to know about what changing colors on my device do...I've heard that it helps battery somewhat but i didn't know if anything else. Like making certain colors pop more or whatever. Just curious about what some peoples thoughts are on this and if anyone has their phone set a certain way with colors that makes their phone "pop" out or looks better.....i would like to see some screenshots and what settings you guys have on your device....much appreciated if anyone can show and help me out. Thanks

Sweet....thanks, so what does that all do to your device? Battery battery life, better color saturation or whatever? I'd like to know the point of doing this to the device and benefits...or if its just for personal fun

So no one is willing to explain any of this to me?
Sent from my Galaxy Nexus using xda app-developers app

all it does is adjust the screen color/gamma. any difference in battery life would be a placebo effect. it might sound kind of pointless but i know that i and probably alot of other people would go insane if we lost the ability to adjust the screen like this. im a sucker for screen with lots of gamma reduction, the colors look so much more crisp and vivid; you can make it look damn good. decreasing the gamma will help make the colors crisper and less washed out, and the blacks blacker. you can also change the color balance -- some people notice a yellowish tint on the stock rom, adjusting the color values you can completely remove any tint and achieve a pretty true white.
edit: regarding screenshots, you wont see anything from a screenshot. screenshots show what the system is rendering, not what the screen is displaying. heres my settings, they may be a little too dark for you:
gamma adjustment - 0
red - 0
green - 0
blue - -3
color multiplier-
red - 153
green - 156
blue - 199

Yeah some people's are slightly different, it dependant on the rom they are running. It's hard so say what to set yours at, some screens just don't look the same as others at the same settings. I would just get a few pictures you really like, put them on you sd card and use them as a reference to adjust them, just pick whatever looks best to you, that's what I did.

If you use Franco kernel updater app, trickster or tkt from play store you will have more options. Gives you ability to calibrate the screen to correct for poor color, mine is beautiful, that's why I can't leave this phone.

Settings will be different from display to display. Also from brightness settings can potentially have an effect on how things look too. Unfortunately there is no universal plug in these numbers and your display will look great. Also, a bit of subjectivity can come into play here as well. As mentioned using a picture of something you know and adjusting settings until it looks right is a great idea.
http://forum.xda-developers.com/showthread.php?t=1790325 <-- that thread has a discussion about various settings, including a spreadsheet in the OP where there is a list of them. Which once again shows that people's settings are all over the place so you probably will have to do some tweaking to get them how you want.

And by calibrating, it will automatically change the colors for you for the best looking results?

Not automatically, you will need to put in things manually look up calibration color galaxy nexus as there are lots of posts and charts saying what people use, pick one that is close and tweak it from there

Alignment shifts when weather updates

In a text widget, the alignment shifts across when it changes weather pattern, so from "light rain" to "wind" obviously as one is shorter it shifts along losing alignment. Why can't it just work from a margin?

Did you try changing the alignment option of the text module? If you want the text to align to a left or right edge, just set it appropriately and the text will stay oriented. As a sidenote: if you leave the align option on standard, it will align to the choosen anchor point. So if you use center, the text will also center. If you use center left, the text should align left.

No the problem still happens when the word changes. It shifts over a bunch completely out of line with others. I'm baffled why it just can't align

I'm a bit OCD. Can anyone recommend a clean-looking font that might resolve this "single word broken across two lines" junk? Or perhaps there's a workaround of which I'm currently unaware... TIA

Try to change the system font . Just a suggestion

Or font size

No dice

Changing font won't help. Since its the length that mather, if it overides a specific amount of letters then it will push next letter down.
So you will have to rename the app if you can.

Try increasing your Minimum Width DPI setting from 411dp to something like 460dpi in Developers Options
