must be a typo in his gamma settings -10,0,10 is ALOT better (=
aren't there going to be alot of variations in screens so there wouldn't be one set of 'perfect' settings for all?
Yes i can

1. Connect your phone to PC
2. Download and extract attached .rar file
3. Open extracted folder and double click on "FixNexusGamma.bat".
PS. make sure you have enabled "USB Debugging" (go to Settings->Developer options to double check).
You're welcome.

I'm sorry, but this is not entirely right.
Your recommended settings are correct for srgb as rgb working space - srgb however has a relatively low gamut compared to adobergb and ecirgbv2. Also, srgb should only be used by web designers, as it is also the native mode of every computer display. Photographers should use adobergb (native dslr color space) or ecirgbv2 (f.e. prepress retouching).
here are the official calibration targets for each color space:
srgb
Gamma 2.2
Color temp 6500k
Whitepoint 140cd
AdobeRGB
Gamma 2.2
Color temp 6500k
Whitepoint 120cd
eciRGBv2:
Gamma L*
Color Temp 5000k
Whitepoint 120cd
None of these settings are good for practical use tho (in prepress at least).
For best color accuracy, I recommend a color temp around 5700-5800k, 140cd and L* or 2.2 gamma, depending on your rgb working space (adobe or ecirgbv2).
photographers should use ecirgbv2 or adobergb, depending on what kind of work he or she does. ecirgbv2 is best suited for prepress use, as it offers the best color conversions to ISOCoatedv2.
General note:
whitepoint should always be adjusted to look like a white sheet of paper of your favorite photo paper.
color temp should always match the grade of white of your fav photo paper (bleached paper f.e. has a higher white point as yellow natural paper)

I tried the recommended settings in the first post and the screen looks pretty nice. I was very intrigued when color control was released and couldn't wait until someone used their HDTV calibration sensors on the phone.
The only thing is now contacts looks a little blue when before they were grey. Can someone confirm the color of the contacts list (click phone and scroll though either recent calls or contacts). The top is still a nice inky black but the contact labels look blue now when before they looked dark grey
My problem is more that colors are OK for the most part but the grey scale is off and everything looks grainy and flat. My dads nexus I set up for him has a bit greener screen but the settings screen color transition is much smoother looking and colors are not flat and grainy. My color scale transition is not smooth and I can visibly see the greys as bars. Its almost like playing a video game and raising gamma in game too high. It washes everything out.
Can I use the bat file without using a color control kernel?
