Purple Tint CURE
OK. It is known that a respectable amount of GNexs' displays are plagued by a purple tint.
Some thought they just had inferior display panels. That's not the case. They are just badly calibrated.
I tried, in vain, to fix the tint by using the partial calibration controls offered by some custom kernels and TricksterMod, etc.
It made the things a little better but that was it. The problem remained. So, I researched a little and finaly
I compiled a pair of AK kernels, one for Android 4.2.2 and one for 4.3 with fixes at the panel driver LUT (Look Up Table).
Those of you that have a purple tinted display go ahead and flash them. Post your findings here.
P.S. Of course your Trickster color settings should slightly change now
