[Q] Color control without custom kernel on JB

Hi,
Having been on JB for the last week and having tried many JB kernels (Trinity, Franco), they just don't seem to match the performance (and battery) of the stock kernel currently.
However, I absolutely need the color control features that come with these 3rd party kernels as my stock GN has a terrible yellow tint to it.
What I would like is if I could stay on the stock kernel while being able to alter my screen colors. I've tried to use the experimental Voodoo app that was test released a few months ago but it didn't seem to work.
Does anyone know of an app or something I could flash that can allow me to alter my colors on the stock kernel?
Any help would be appreciated.

Nope not possible . These files are apart of the custom kernels... and only the kernel has the ability to tweak the absolute color values. So the only way to get the color control is to flash back.

So, it wouldn't be possible to (theoretically) modify the stock kernel to just include said color tweaks, and nothing more?

Man would I love that.
Another annoyance with 3rd party kernels is that they slow down after a period of time and requires a reboot to speed it up again. So far, I'm back on the stock kernel and it's still flying after heavy use.

Everything slows down after a long period of not rebooting. Cache builds and the system needs a restart.

Less so with the stock kernel from my experiences. I have no issues with restarting my phone once in a while but doing it every few hours gets exhausting.

Few hours? No days yes... I've never had a kernel slow down within hours. That would be yours apps building cache... the kernel... ironically is what empties it.

Takes three seconds for gnex to wake

I have a problem when i put my phone to sleep it takes like 3sec to turn back on after pressing it and I often end up pressing it like 5 times before it works I'm on codename-android-3.3.0

What governor are you using and are you using a low screen off profile?

Same for me. I haven't messed with any governor settings either.

This is a common issue on codename, the sprint forum has been full of similar comments.

No issues here using cna Rom with the trinity kernel. I've been try to reproduce this issue all day but can't seem to do it. Works perfectly here.
Try reflashing the Rom like this.
Wipe data, cache, and dalvic.
Then format system, data, and cache.
Flash Rom, flash gapps, flash kernel of choice then reboot. Log in, let Google sync, reboot back into recovery and fix permissions.

Lag after a day

So why does my phone start to lag after a day. No matter what ROM or kernel I am on, after about 20 hours my phone starts to lag. If I restart my phone all is good. Does anyone have an explanation? Is this a great 4.2.2 feature? This wasn't happening before that.
Sent from my Galaxy Nexus using Tapatalk 2

Is that even pure stock? There are several posts on this already. There isn't a genuine solution but some have suggested some ways to minimize lag on 4.2.2.

I have tried all sorts of ROMs.I will look for some of the other posts. Its just frustrating because I can get it to fly, but have to reboot 1-2 times a day.

Check your memory usage. I have this problem too - and it seems like my memory if full. Try to see what services run in the background and maybe you can stop some of them. Also look at 'Greenify' - it is an app that stops background processing for apps you don't want hanging in the background. It requires root, though.

do you use twrp? i had that problem until someone mentioned that twrp doesnt wipe completely and used cmw.

I installed greenify and will see in a day or so if it is working. Thanks for the tip.

would it be too much of apps running at the background and causing it lag?

I'm reading about this issue more and more everyday ... one solution i saw was that to install "Clean master" from Play store and clear cache with that to minimize lag i believe it only affects custom roms and not stock based roms :/

Screen flickers after CRT animation when turning screen off?

I have been having this problem since i switched to jb 4.2.2 and I've been through 3 ROMs. Aokp, Cm 10.1 and jelly bam. The flicker is still there. Has any body found a solution to this yet? I can live with this but it really bothers me though.

[Q] Screen Not turning on

When I have the phone in my pocket while ringing, the screen is blank after pulling it out of my pocket. I have to press the power button to turn on and answer phone. Is there a fix for this? I've tried running different Roms with same results. I'm currently running Carbon Rom 4.2.2. Please help. Thanks.

If you can reproduce this issue on pure stock (flash ruu), then it sounds like a problem with the proximity sensor. Try cleaning the sensor area (upper left of the phone) and see if it helps.
