Thanks. I thought about flashing PA initially but I'm really happy with the way it is at the minute. I haven't seemed to have lost any notifications that I'm aware off and I use launcher8 which is a fantastic version of the Windows 8 phone front end. live tiles etc etc. Sure makes a difference from the usual iPhone / Android icon screens. As you can see Button Savior sits nicely at the bottom and I can hide it when needed and a quick dab on the unhide button brings it back.

BUT..... I'm a fickle sod :D I like how PA and the Pie works. I may just give it a rip.

impossible. it took months for something simple like getting straight colors to emerge. before that all we had was rgb, which was a joke. and thats still just using whats already there. local calibration, even if there'd be a reason to do it, that would mean you're rewriting the kernel. dont get your hopes up, that will never happen. :D

I've checked gamma on a few of the kernels and they're way off.
[Nexus 4 Q&A, Help & Troubleshooting] molesarecoming:
googles default kernel isn't 2.2 either, but even if, thats simply not how it works - youre still tied to a physical display having its own rules. im sure you can get number perfect states but you must watch out for things like banding then or blown out highlights. gamma itself is the least of my worries, i even like less gamma counteracting the lcds inability to display blacks.

take googles kernel issues for instance: bad color bleeding, green neutrals, heavy banding in the grays (dialer), insane whitebalance, purple blues, greenish tint overall, liveless colors --- thats whats making it so hard to cope with, not the gamma. but if you do find 2.2 base sets without issues, more power to you. i will put them up there or integrate them. but overall i'd not give too much value to that market app though. :)

Re: Let's calibrate Mako

2nd revision, first variant is quite nice. I do notice some slight green banding, and gray, yellow and cyan gamma seemed a bit high, but aside from those minor things I think what you've done is fantastic! Color balance and white reproduction is very nice.

I wonder if the banding I see is due to my particular panel, I have a rev10 and from what I've read, it seems like the panels in rev11 might be a little different.
[Nexus 4 Q&A, Help & Troubleshooting] molesarecoming:
i cross checked and i get pretty much the same level of banding with the original google stock kernel. in some cases (dialer) stock is even worse. what mine doesnt like is green/cyan gradients. but i've dialed it down to an amount im ok with. stock behaves better here. maybe i should desature the green channel a tiny bit to compensate.

Re: Let's calibrate Mako

You're absolutely right, in my post I actually forgot to mention that the green banding I was seeing was also present on the stock kernel (wtf Google). I could see the desaturation of green helping a bit like you were saying, I'm honestly just surprised that in a matter of days you've managed to greatly improve upon the stock mako settings. Guess display calibration wasn't a big priority for Google or LG :-/
[Nexus 4 Q&A, Help & Troubleshooting] molesarecoming:
wwell its dark by design ofc, even the title says so. stock has ill saturation, its way off. it happened because they're cranking the blue channel and cutting white and blackpoint in half, so the entire spectrum is missing. i think what you see with rev2/1 is more or less how colors look on an ips panel. if you do like less saturation just go lower in the defines i made. btw, the manufacturer of the panel uses more saturation in their factory setting than i do, but it started to look cartoonish so i dialed it down.

white balance

i'm running the motley kernel on my nexus and i hooked up a spyder4 to calibrate my white point using (just) the kcal values.

what is astonishing is the values i attained:

255 230 205

with those values i get a nearly perfect 6500K white point.

the gamut compression is unreal, though.

i lose 20% blue, 10% green, and the display is much dimmer (if i had to throw a dart, i'd estimate 30% dimmer =]).

what's worse: nothing i do with the gamma controls affects the white point at all.

at first i thought to myself, it's not worth it: the display is so much dimmer

then i started swapping between the adjusted and factory white point and i about wanted to puke.

all the highlights were blown, everything looks ice cold, and nothing looks realistic anymore.

next i'm going to profile the gamma curves and color space. i'll post the data when i'm done.

more updates

i managed to install the lut in my kernel!

i'm away from my colorimeter right now, so i can't test the result but it looks very promising.

for those who are interested, i wrote some gamma calibration scripts to automate the selection of gamma settings.

these are intended for motley's kernel, since it has dynamic gamma support.

i'm not going to zip them (too small): instead i'm just going to paste them inline.

these have to be run on the device (duh).

$ sh gam-adj.sh $white $mid $black $contrast $bright $sat $grey

this script sets all the gamma parameters.

pretty straightforward. once you choose your settings, you can modify it, put it in your init.d, and make your adjustments permanent.

the commented settings in the file are ones i found to work very well. (no banding, good shadow detail, good brightness)

you can also use the script to set your kcal settings (but you have to edit the script for that).

===================== gam-adj.sh ======================

#!/system/xbin/sh

kcal="255 255 255"

kpath="/sys/devices/platform/kcal_ctrl.0"

white=$1 #128

mid=$2 #71

black=$3 #117

contrast=$4 #8

bright=$5 #0

sat=$6 #13

grey=$7 #20

gpath="/sys/devices/platform/mipi_lgit.1537"

echo "*** gamma ***: $white $mid $black $contrast $bright $sat $grey"

string="$white $mid $black 0 $contrast $bright $sat $grey 2"

sum=`dc $string + + + + + + + + p`

red_string="$sum $string"

echo "red: $red_string"

string="$white $mid $black 0 $contrast $bright $sat $grey 2"

sum=`dc $string + + + + + + + + p`

green_string="$sum $string"

echo "green: $green_string"

string="$white $mid $black 0 $contrast $bright $sat $grey 2"

sum=`dc $string + + + + + + + + p`

blue_string="$sum $string"

echo "blue: $blue_string"

echo $red_string >$gpath/kgamma_red

echo $green_string >$gpath/kgamma_green

echo $blue_string >$gpath/kgamma_blue

echo 1 >$gpath/refresh_screen 2>/dev/null

echo "kcal: $kcal"

echo $kcal >$kpath/kcal

echo 1 >$kpath/kcal_ctrl

$ sh gam-cyc.sh

this script automates the selection of gamma values.

it needs to be run in the same directory as gam-adj.sh.

edit the script, run it, and it will cycle through gamma values in 1 second intervals.

===================== gam-cyc.sh ======================

#!/system/xbin/sh

white=128

mid=71

black=117

contrast=8

bright=0

sat=13

grey=2

start=0

end=255

inc=1

for contrast in `seq $start $inc $end`; do

Hi, I'm using paranoid android 3+ with Faux kernel. I've tweaked the colors using FauxClock. So I just have to flash this zip from CWM right? Nothing else required?

Thanks in advance! :)

No, if you flash one of these kernels here, you acutally replace the faux kernel with it.

I recommend you to download FauxDisplay if you want to stay on faux kernel and use these colors.

Hello Guys, please tell me whicj variant from 1st post is the best one ?

I'm using newest PA, with stock kernel. If I flash my N4 with the kernel listed in first post everything will be ok ?

Really?

Everyone's eyes and preferences are different. You have to try them and see for yourself.

here's the kernel I calibrated with the lut.

make a nandroid!

host$ tar xzvf boot.img.mako.tar.gz

host$ adb push boot.img.mako /sdcard/

host$ adb shell

jellybean# cd /sdcard

jellybean# dd if=boot.img.mako of=<can't remember the name of the boot partition>

reboot system

Looks terrible on my screen. Would be nice to have gamma control as well.

Do I need to change RGB values to 255,237,213 after installing the kernel or leave as is?
[Nexus 4 Q&A, Help & Troubleshooting] symnem:
the gamma is set to 3 on the bottom third and 2.1 on the top 2/3 (more low end spread, higher brightness). you should not adjust kcal (temperature control) because temperature control just performs a linear transform on the lut (would be superfluous) .

i wouldn't really expect it to look right on your screen, though... it's calibrated specifically to my screen.

if you want gamma control, try motley's kernel and the scripts i posted earlier.

also, you should remember that d65 (6500k) often looks very warm when you're coming from a higher color temperature; iirc, the n4 defaults to something like 7400k.

if you want to check the results, you should either run a calibration or look at some images on Flickr or a professional photography site where the images are properly balanced.

i found the most noticeable change in the reds (default reds were wildly inaccurate).

OK, thanks. I thought you may have changed white point prior to creating your LUT. I understand that it isn't calibrated on my screen, but equal screens have similar characteristics. It is way better than lg or google stock conf. on my phone, that's for sure.

Thank you very much for this molesarecoming.

For cons, I think the "2nd rev, 2nd variant" better. I have to buy new glasses ? :eek:
