[Nexus 4 General] figuremania:
I'm seeing none of those with R82 at the moment. only time I had problem with franco's kernel was after upgrading to 4.2.2 and flash Franco's back to my nexus 4, then tried to set my previous UV setting. Things went downhill so fast lol..... I had to wipe and reflash the whole thing but after that it's all fine. Sorry for OT :/
[Nexus 4 General] Sucalakafufu:
So I took Faux's original recommended settings and used it as a base. My goal was to make the colors a bit darker and to remove the yellow tint without straying into the blue tint.

I ended up with the following FauxDisplay settings:

LG Presets

Color:

255/255/255

Gamma Amp 0:

31/31/20

Gamma Amp 1:

0/0/0

Gamma Gray Scale:

2/2/2

7/7/7

3/3/3

3/3/3

6/6/6

7/7/7

Gamma Gradient:

0/0/0

0/0/0

0/0/0

2/2/2

2/2/2

0/0/0

3/3/3

Screens can be different. So if you still see a yellow or blue tint I suggest you move the blue slider in Gamma Amp 0 up or down until the tint seems to disappear. :)

Using my old LCD HTC Desire atm as i've sent N4 for repair. All colours in display tester are on or very close to 2.0. Including grey. Seriously? On a 3 yo hardware? And colours look amazing. Blacks are not as deep though. I mean LCD panel is a lot more inferior than on N4 and they still managed to get brilliant calibration. Yes, it's lower, but it's even, and even at 2.0 colours are very vibrant on it. I think i'll have a go at display app once i get my N4 back, surely good colours can be achieved.

FauxDisplay doesn't really work with Harsh's enhanced stock kernel. It seems that all the gamma values are being lost instantly once the screen turns off and on. I understand though that his stock enhanced kernel should support Faux-style gamma controls. Is my understanding wrong i.e. I should not be using FauxDisplay on Harsh's enhanced stock?

For anyone who has the time (because I'm swamped with work lately), can someone do a quick rundown of how to translate the old values of Franco's gamma settings to the new numbers? So I can edit the lines on the Gamma spreadsheet that contain the older numbers.
[Nexus 4 General] mcg:
This yellowish tint is a hardware limitation of the panel, at least from what I garner. It's just the quality of the display, where when you look at the screen from different angles you either get 1) yellow tint or 2) negative blacks. The iPhone 4 screen did something similar to this.

The iPhone 5 screen does not have this kind of problem, which is something I miss.
[Nexus 4 General] Ok_Kaleidoscope5109:
I think there's been a post in Franco's thread where it's difficult to convert old to new. They tried with visceralpsyche's settings for a while and couldn't reproduce the same settings in the old settings. We ended up waiting for him to return and give us his new settings for the new Franco app. So I think the safe thing to do is to just ignore the old settings and move on. Most of the active users like Kel Ghu and Obsanity, etc who were quick to adopt the new app have already updated their settings and it's scattered somewhere in the Franco thread.

Hi,

I've got the latest stable Faux kernel, the latest FauxDisplay app and Android 4.2.2.

If I let FauxDisplay app running in the background my color works but I as soon as I swipe it the next screen off-on I keep the right color but I go back to stock gamma. I need to relaunch the app and let it run in the background to make it works.

When I reboot the phone the colors are right even if FauxDisplay is not running but again if I make a screen off-on I'm back with stock gamma.

Anybody as the same bug?

If it can't be corrected is it possible to hide the app from the swipable list?

Thanks again for the fantastic work!

[Nexus 4 General] halluci293:
For those of you with franco's kernel and franco's kernel updater app, the new update incorporates the screen calibration images that I created. You can switch between them by tapping on the image area in the gamma adjustment window. I find that using these gamma test images, the results are quite different from display tester's gamma tests. I believe that the display tester's gamma test images are flawed for a few reasons:

- they use a checkerboard test pattern, rather than the standard parallel bars. Search online, and you'll see that this is NOT recommended.

- they only test a single luminance level, and I'm not sure if that luminance level is even 50%. Since gamma is a function defined for all luminance levels 0-255, calibrating a single point on this curve does not guarantee that your curve is calibrated elsewhere.

- I'm not really sure what's going on in between display tester's bars. For example, in the gray gamma test image, I get a weird green tinted background between the bars that doesn't match anything. I know you're supposed to match the centers and edges of the bar, but not sure what the purpose of the background is.

The new images are, in order:

black/white levels:

- top half shows black checkerboards increasing in steps of two; the lower the number that you can still see the checkerboard, the better black levels you have

- bottom half shows white checkerboards increasing in steps of one; the higher the number that you can still see, the better

KRGB gamma at 75%/50%/25% luminance going from left to right, top to bottom:

- all squares should blend into their respective borders. The fourth image is a more rigorous gamma test than this one.

Color banding for KRGB:

- all gradients should be smooth even transitions from left to right.

Gamma at every luminance step from 0 to 255:

- all bars should blend in with the black to white gradients. any color casts you see are deviations from 2.2 gamma.

- the top horizontal strip is 0-255 with the gamma test bars in vertical orientation

- the bottom strips are 0-127, 64-191, and 128-255 luminance steps from left to right respectively

- this also doubles as a banding/gradient test, as the background black to white gradient should transition smoothly everywhere.
[Nexus 4 General] gio_punsalan:
Hey guys. Did anyone of you try to calibrate using the htc one x as the base? The HTC One X's screen is beautiful. The color reproduction is phenomenal, comparable to those with 1080p screens. No matter what I adjust in the gamma, I could not get the HTC One X's colors. Did anyone of you try? I'm a noob at calibrating so that might be why I can't reproduce it.

Custom kernels have another stock screen values ? For example i flashed franco kernel and the screen Looks extremely washed out when is at 100% brightness , it didn't look like that on the stock 4.2.2 kernel

Also I tried to get the gamma values from moles (revision 4) and I was not able to replicate them , I can only choose with a slider and got different values , gamma works different in every phone ? Or maybe his values are just exclusive to the paranoid android kernel ?

I have a problem pertaining to my FauxDisplay app that I have tried to clear cache/data and reinstall multiple times. If it makes any difference, I also have FauxClock installed, use SuperSU, and am restoring a custom color profile. The problem is that any changes I make to the "color temp" tab do not stick, but everything else saves properly. When I turn the screen off and on again, the color adjustments show values that I never set and they sometimes change too. I would appreciate it if anyone can provide any insight into my problem.
[Nexus 4 General] droidmeup:
For the color temp, change it individually and screen off/on on each value. That's the only bug left that I know after the latest update. Backup and restore are working flawless.

[Nexus 4 General] Dovucoe:
Thanks to ghost_og's post, I've figured out how to translate from Franco's values to Faux.

Below is a snippet of Java code that does the trick:

gammaFineGrey0815 = greys & 7;
gammaFineGrey1623 = (greys & 0b1110000) >> 4;

gammaFineGrey2431 = mids & 7;
gammaFineGrey3239 = (mids & 0b1110000) >> 4;

gammaFineGrey4047 = blacks & 7;
gammaFineGrey4855 = (blacks & 0b1110000) >> 4;

gammaAmp0 = contrast & 0x1F;
gammaAmp1 = brightness & 0x1F;

gammaGradTopHalf1 = saturation & 7;
gammaGradTopHalf2 = (saturation & 0b1110000) >> 4;

gammaGradBottomHalf1 = whites & 7;
gammaGradBottomHalf2 = (whites & 0b1110000) >> 4;

// Retrieved from franco's settings.
final int set4values = 0x0;
final int set9values = 0x02;
gammaGradUpper = set4values & 7;
gammaGradLower = (set4values & 0b1110000) >> 4;
gammaMidPoint = set9values & 7;

Wouldn't mind someone double checking it, but this should be correct. It should also be possible to do the conversion the other way round from Faux to Franco's values, except Franco's has no way to set the Gamma Grad Upper, Lower and MidPoint values it seems. They're hardcoded into the kernel.

Hopefully this means that the community can actually share colour tunings regardless of which kernel you're using now.

i don't see those in the trickster app

I am on the Motley Kernel and downloaded Trickster however i see that most people are using FAUX kernel and using FAUX display app as in my trickster app my Gama control settings look different and have 3 RGB sliders compared to the other settings i see people posting.

overall I'm just a wee bit confused as to how to adjust colors and saturation in in trickster. I am coming from the Halfbreed kernel and loved that saturation but now that i'm on Motley I would like to get those colors back.

[Nexus 4 General] bigeyes0x0:
You can't exactly convert franco's values into faux's values because franco missing two columns of values in faux's interface (total 9 registers, or 9 sliders in my app). For more information check this conversation on github https://github.com/motley-git/kernel-Nexus4/commit/0c6c276fb8907128c623d57699f9c7ac365e947b and related links.

In the latest beta posted on G+, we support both interfaces but prioritize faux's interface for kernel that supports both because of this reason.

EDIT: Fixed failed math, on my part 9 registers not 6 or 12. Was sleep deprived lately.
