Nexus 5 Gamma Reverse Engineering App is out!

(This app will work on the common sysfs interface, so any kernel using this interface will be compatible with this app, not just my kernel)

Please download my public betas here:

http://faux.androidro.ms/hammerhead/beta/

Franco Kernel is also compatible here:

http://forum.xda-developers.com/show....php?t=2508284

ALL Gamma registers are accessible with new APK!

@myfluxi Thank you again!

After hitting apply, it's best to turn screen on/off to see the results updated!

Please help decipher the meaning of these values and write them down in a concise manner so we can all understand what you've done and tried.

My TODO list for this FREE app:
Once things are figured out, I will add:

1: "Set On Boot" options to automatically apply the new values on startup (right now "set on boot" can be dangerous and lead to black screens).
2: Perhaps some basic profiles
3: Maybe other cool stuff if time permits


Min Value is 0 (NO NEGATIVES)
Max Value is 255 (Don't Go over it, it will break stuff!!!)



App Change Log:

1.0.6 - Initial release with RGB register access only
1.0.7 - full access to all registers
1.0.8 - add "set on boot" feature, add webview link to 2nd post below, enabled landscape mode.
1.0.9 - updated to latest kernel driver. add old version warning. add action bar for quicker navigation.
1.0.10 - updated to latest kernel driver. removed unused fragments.
1.0.11 - updated to latest kernel driver with stable sysfs locations!

Progress So Far:

Gamma Tabs:

columns => goes from left to right, so 1st position is most let and right most is 5th position
row => goes from top to bottom.

I got VERY CLOSE to ideal Gamma 2.2

Positive and Negative Polarity tweak added. This allows for greater RGB gamma control and balance!

Overall Color Gamma Curve (row 1 column 1 of RGB Gamma tabs) => 0 is highest, 255 lowest
Red Gamma Positive=> 0
Green Gamma Positive=> 73
Blue Gamma Positive=> 78

Red Gamma Negative => 0
Green Gamma Negative => 73
Blue Gamma Negative => 78

Gamma Color Brightness (row 2 column 5 of RGB Gamma tabs) => 0 is highest, 255 lowest
Red Gamma Positive => 100
Green Gamma Positive => 117
Blue Gamma Positive => 121

Red Gamma Negative => 107
Green Gamma Negative => 117
Blue Gamma Negative => 121

Overall White Point Brightness => 0 darkest, 255 brightest
Gamma white point, Column 1 => 30

this is to help reverse engineer the kernel drivers. it is relevant in this section for kernel development.
