Kernels with Trinity contrast - Samsung Galaxy Nexus

What kernels, other than Trinity and Franco kernel, have the Trinity colour contrast controls? I've spent so long with those two kernels that I have trouble getting used to anything that doesn't have it.

use the trickster app to control the contrast of any kernel .. try and see

... Huh. Thanks!
(I had a script to set the contrast and colour controls. I assumed it wouldn't work on other kernels without actually testing it. Turns out, it does work.)

[Q] SetCPU

My SetCPU has only about 3-4 different frequency options between 806Mhz and 245 MHz. Is there any way to increase the number of options between these two frequencies?

U have to root your phone and flash some ROMs depending on which type of rom do you like, it comes with kernels for overclocking or you can flash one if you want to. Rooted stock rom doesn't have any compatible kernels it breaks some stuff so you really need to use a different rom..

Well if he's using SetCPU then he's already rooted, so he's got that covered.
OP as jojo stated, you need a custom kernel to allow overclocking. A lot of people seem to be fond of Pershoot's OC kernels, but I personally just use the one thats included with CM6 and now CM7. It allows an overclock up to 1.5ghz.

I think he's wanting to know how to add more underclock frequencies. It can be done but you have to decompile the kernel in order to do it and also have decent knowledge of voltage tables (since the purpose of underclocking is to save battery power you have to uv also). Probably well beyond most peoples comfort level however, if the op still wants to attempt it are numerous threads with info - just search for something like 'creating a custom kernel' or 'make a kernal'. One of them is located in the G2 development forum.
Oh ok thanks guys. Yeah, I have Pershoot's kernel so that is not a problem. I was trying to include more underclock frequencies, but if that means editing or creating my own kernel then forget it lol, I'm no expert on that.

There's a turbo ROM that can deep fry your G2 to 1.8ghz, and it has a lot more frequencies below 806.

[Tips] Screen Color Calibration for the Galaxy Nexus

After using the Galaxy Nexus for two weeks, I found the screen color of the new amoled+ is much better than the Nexus S, but still inaccuracy. I'm a part-time photographer who keen on the right Gamma, color accuracy and color temperature.
So I just finished some test with such things:
Galaxy Nexus
franco Kernel 18.5 nightly(with the ColorControl from Ezekeel)
Voodoo Screen Test app
x-rite i1 Display 2 color meter
HCFR software
The test result was not so good...
Average Gammar value is about 1.9, far from the ISO stand 2.2. So the color is just too bright (I'm not saying screen brightness).
The shadow part (0-40% gray level) of 3 color curve were almost out of trim. In another words, incaauracy color balance.
As the color unbalance. The color temperature is starting from lower than 5500K to 6500K, which the ISO stand is 6500K at any color level.
I also tested the ColorControl in franco Kernel. After the adjustments, Gammar value is still bad, but I save the (most part of) color balance & color temperature in the end.
The adjustments step by step:
Make sure you have a rom/mod with /init.d autorun function.
Bye, stock rom...
Make sure you have a kernel with ColorControl function.
Such like Ezekeel, franco...Else? I don't know.
Set the screen brightness to 50%.
It's the mesurement "baseline". But why 50%?
Because, at this point the screen has a brightness about 120 Lux--also a ISO stand. So, it's very close to our desktop LCD.
Make a new file as /etc/init.d/900colorcontrol-b50
Which could be done by Root Explorer or adb.
Inside the file, type such line:
Code:
echo "-10 0 -10" > /sys/class/misc/colorcontrol/v1_offset
echo "1820000000 1900000000 2000000000" > /sys/class/misc/colorcontrol/multiplier
I choose "182 190 200" here, because the default value was about 200. Rising will increase the risk of LED Burn-in.
And, don't forget the 7 zero!!!
Just reboot & enjoy the almost right color temperature.
It's (6500±300)K at any color level in my device. Not perfect, but much better indeed.
Done, that's all I can do for you.
Thanks so much for the mod.
I'm willing to test your new calibration for the GNex color but how can I revert back to stock in case of problem ?
So I guess we can only use this modification at 50% of brightness ? If we change to auto, how could it be ?
Sorry for being a noob here, but this is compatible with any rom/kernel right? I'm currently running on AOKP Build 25 and Popcorn kernel 7.1
Thanks,
Mosh
Hi, and thank you for offering your expertise. I'm not confident in doing the above.... Can you offer a little bit more step by step?
I've played around with root explorer which I imagine is what is necessary to change these values.you lost me at the 2nd step.....
Also, is 50% necessary?
Thanks kindly,

You can change all of these settings from Franco's kernel updater program directly without modifying any files.
The OP's settings appear a little warm at first but I'm liking them so far...

Can you please add this file 900colorcontrol-b50
sooooo do i make a folder in system like this?
system/etc/init.d/900colorcontrol-b50 and then add that text above or??
Instead of making that script, can we just input those numbers into the Color Control?
-10, 0, -10 for Gamma (RGB);
182, 190, 200 for Multiplier (RGB)
Right?
Thank!
your feeling about color is exactly. Gray is dirty, it's not sync at all pixels.
I hope someone changes this by kernel - easy for me control everything
After flash franco kernel it's better more but not perfect.
If this problem is not improved, i'll buy other phone that uses Superamoled PLUS replace this one . HIZzzz
These settings look green to me

Indeed... especially settings menu looks very greenish!
But maybe I get used to it...
Edit: Maybe a typo? '-10 0 10' looks not that bad at all ;-)

And that would do absolutely nothing
SAMOLED Plus displays are identical to the SAMOLED HD displays when it comes to colors and such.
It would be better and more easy if someone was able to do an app like this one that works for the Nexus One :
http://forum.xda-developers.com/showthread.php?t=745248
I really miss this app since I've bought my Galaxy Nexus
Thanks for the info. I had mine looking very similar but with a combination of lower brightness and higher multiplier values. Nice to have it set now without the additional risk of burn in. Thanks a ton.
screen looks greenish compared to franco's recommended value, using his instead but thanks for the write up.

must be a typo in his gamma settings -10,0,10 is ALOT better (=
Great find colors are much more accurate now
These settings are way off on my device, its too green.

[Q] Custom Kernel, Any Advantages?

I'm not really looking for anything in particular, I just like modding and improving my Nexus 7. Are there any true advantages to a custom kernel that will increase performance and productivity? I know there's kernels which allow overclocking, I'm not sure if it's worth it when in comparison with battery life. The Nexus 7 is already speedy enough, but is there a benefit to overclocking to maybe 1.7GHz or 1.8GHz CPU?

if you're on 4.3, I can highly recommend franco.kernel. Great battery life, and allows overclocking.
Benefits are overclocking aren't really that great, especially if you can run everything fine. However, it does come in handy if you're playing graphics-intensive games and there is a bit of stutter.

ElementalX, Glitch, Bulletproof (ElementalX-based), to name a few. Running ElementalX 2.3 myself, and it's rather great :good:
Saw something about this, thought it was kind of cool.
I'm currently running 4.4.2, came across Gangstar Vegas, and it's an amazing game, it just stutters a bit. What would be a good kernel, and clock speed for running the game more smoothly? I don't care about battery life much because I'll just change the clock speed when I'm dome playing.
I'd clock it to 2.0GHz, but I don't want yo overheat the device. Suggestions?

Custom kernel could have e.g. CIFS and/or EncFS kernel module support.

Is there any way to have this double tap to wake feature without flashing a custom kernel? Maybe there's a .zip file that can be flashed to have this feature alone without being part of a kernel?

There's also an app in the Store which does the same thing but a) forgot the name (if I remember I will update this post) and b) it's not as low-level as this kernel and so I would assume it will use the battery even more than this. This ain't "free" as well, for the record
I think enabling volume button wake is also useful, as the volume rocker is much easier to find than the smaller power button. Not sure which kernel does that though.

Calibrate screen colors?

I usually would use Kernel Adiutor, but it doesn't show the Display section on whyred. Any suggestions?

you need KCAL support stock kernel doesnt have kcal drivers. you need custom kernel that supports kcal.. example insigniux or kirks kernel.

kirks has OC adn UC but hasnt been update in a month..
am using insigniux similar to stock but has kcal and schedunt governor.. no i never use stock kernel thats the reason i unlocked bootloader..
yes colors are subdue. i use saturate and add 3 points value.

So the thing is - I know nothing about kernels! Have never flashed them, don't really know what they do, so I've always kept stock. Any ideas where to begin to understand more about them (besides digging through the forums)?
I see Blackbox and Kirks cited a lot. How would those compare to Insigniux?
Also, I'm on stock Global MIUI (rooted of course), and want to stay on that for a while, but later am planning to go to LOS (or maybe another custom ROM). Would I need to change kernel in that case?
Thanks for your help, btw!

they are all different.. i first flashed balckbox but didnt have many extra options seemed like a stock kernel.. then kirks had more options and i just started using insigniux.. many have claimed that it gives better battery life and its fast..
you can change many things in kernel.. if you want more battery then theres options to make go easy battery but will suffer from performance and speed. then theres ways to gain a bit of battery and keep performance.. and of course performance...
like change governors.. this will change cpu frequencies some are more tamed other agressive.. ect.
