Color banding happens when when the transition from one shade to other does not occur smoothly (may be same color different shades, or diffeent color all togather. So if you take a picture of the sky, you might see one shade of blue ending abruptly and the next one starting, or a sunset sky would look more like one color ending before the other color begins. In a nutshell, colors look bad :(. If there is banding on one particular side of the color spectrum, using other colors may not show it.
[Nexus 5 Themes and Apps] katsuru:
Oh now I get it, sounds worse than I thought.

Im about to sell my n5, just cant put with all this crap, yellow screens, bad color reproduction and so on... :(
[Nexus 5 Themes and Apps] ganeshp:
Install elementalx kernel and choose cooler colors
[Nexus 5 Themes and Apps] katsuru:
That actually made my screen look amazing :D:D:D thanks for the hint man!

Now im facing a new problem tho... out of the sudden my Vibration motor sounds loud... noticed that while unlocking my phone while layin on the table, tought it was the fact that it was laying down that caused it to sound weird... Picked it up, unlocked the screen again, and now it has a loosy feeling to it :confused:

I got in love with this piece of hardware at first... but on and on it keeps getting me in "trouble".

I searched youtube and found 2 vids that describe my "new" vibration:

http://www.youtube.com/watch?v=OATPCPTtUkY

http://www.youtube.com/watch?v=pPhLx29dCpM

It sound exactly like that, loose, noisy and cheap now :laugh:

Enough with offtopic now. Thank you once again for your help
[Nexus 5 Themes and Apps] chikimonke:
If I'm not mistaken, I believe that kernel boosts the vibration motor to 100% power, rather than the stock ~65%, this would definitely make it louder.
[Nexus 5 Themes and Apps] ganeshp:
and to add to that ..just install any kernel tweaker app like trickster ..reduce the vibration to 30ish then apply those settings ..and set it to boot ..problem solved
[Nexus 5 Themes and Apps] katsuru:
Just checked the vibration, its at 63%. The motor just sounds loose, somehow, and not so strong like before. Still this happened 2-5 mins before I flashed the kernel.

Im going to order a new motor and just replace it :victory:

Guys please don't go off topic :)
[Nexus 5 Themes and Apps] bornoxt:
Have you tried the new settings from [MENTION=5543250]mag01[/MENTION] in this post?

I changed my settings to this and they still look a bit more accurate than the old one.
[Nexus 5 Themes and Apps] neriamarillo:
I just tried the color setting option in Phantom Gears version of Franco kernel and it looks amazing. I know it was said that it may or may not be safe but I wanted to try it out and see. Checked with the Display Tester app and colors are all at 2.0 and gamma also at 2.0 no banding.

Now I don't know if I should keep it lol.
[Nexus 5 Themes and Apps] italia0101:
The gamma changes in post 2 are slight, but they are there, the display calibration app does show it changing in the gamma :)
[Nexus 5 Themes and Apps] markwebb:
This does work. Using display tester app my gamma was 2.0; it is now closer to 2.2 thereabouts. Definitely noticed a difference as it has a bit more contrast and not that washed out bright effect. Any hint of yellowing is gone.
[Nexus 5 Themes and Apps] fireproofrev:
Now I also see the changes. Some values will have big effect and some other you can chance from 0 to 255 and will see just a barely noticable change.

on gamma 5 I see the changes instant even without turning the screen off/on. Before I restartet I changed almost all values to 0 or 255 and didn't saw any difference. Maybe the reboot fixed the "not changing" problem on my side.

EDIT:

Now again I have the problem that I dont see the changes. After playing a bit around with the settings I noticed again that nothing Is changing anymore. I went back on gamma 5 to test the good noticable gamma change and it was not working anymore. 0 or 255 at gamma 5 in colum 2&3 don't make a change anymore.

After a reboot it works again some changes and then it will stop working till the next reboot.
[Nexus 5 Themes and Apps] ChazzMatt:
I've installed the version 8 apk several times and all I get is a blank screen when I open. Uninstalling and trying version 7.

Same. Just a blank screen.

Yes, latest beta of Faux kernel is installed.
[Nexus 5 Themes and Apps] varma111:
You need to have faux beta kernel for app to work.
[Nexus 5 Themes and Apps] ChazzMatt:
I HAVE that, also.

I've edited my post above so I don't get 20 more answers like that. Need to know why it's a blank screen when everyone else sees the app gui.

Going to do a restore from backup, re install kernel and app to see if something changes.
[Nexus 5 Themes and Apps] LorD ClockaN:

[Nexus 5 Themes and Apps] TrainNanpaMaster:
This app doesn't just work on Faux's kernel. I can confirm it also works on Franco's r15 beta.

I can also confirm that the color settings will randomly unstick independently of rebooting the phone or not.
[Nexus 5 Themes and Apps] Batfink33:

This app will be free forever. I will add all the feature discovered by the community to this app. This is why it was created in the first place. I will add similar functions to my pay app to as well.

When you first contributed your code I felt obligated to give back to the community as well. This is why I created this app in the first place (I spent hours on this into the we hours in the morning to get this out ASAP so community can help us figure things out faster)

Again thank you for your contributions and I will do the same.

So, no improvement over stock.

We have 2.0 gamma already out of the box. We are trying to get 2.2 - 2.4 gamma.

[Nexus 5 Themes and Apps] neriamarillo:
I know what we are searching for is 2.2 to 2.4. I just tested that seeing since a lot of people were taking about it but nobody really checked if it was actually doing something better. BUT even though it is all at or around 2.0 it looks way better than stock at 2.0 weird...
[Nexus 5 Themes and Apps] rajendra82:
I applied the mag01 settings, and my display appears to be very similar to his, as the resulting gamma is very close to 2.2 for all the colors. Very pleasing results, and saves me from having to get out the colorimeter and do hours of testing.
[Nexus 5 Themes and Apps] JaylanPHNX:
What values (column and row) would I have to change (and in which direction) on each color to get my grays darker? Or am I looking at this all wrong? I confess I don't understand what any of this means, which is why I'm not fiddling with it blind.

[Nexus 5 Themes and Apps] rajendra82:
You need to read these posts by mag01 to understand what these values do, and how to tweak them:

If you don't want to read them all, I can sum it up for you.

For each color there are a pair of 23 values. They are shown as 4 rows of five numbers and 3 remaining numbers in this app, but they are essentially 23 continuous set of numbers. It's best to keep both positive and negative tab values of each number the same for each color. The 23 values shown in order are adjustments starting at the highest saturation for the color (100%) and down to the lowest saturation value (0%). Basically you have 23 points of adjustment for the color curve for red green and blue saturation. Each of these values takes on the form of a number between 0 and 255. There is also a global curve adjustment number labeled as white point, which can take on a number between 0 and 63. So you have 70 values you can adjust to make the grayscale be of correct temperature and luminosity at different brightness levels. Mag01 went through all that, and for his display came up with 70 values that resulted in most accurate results. They are not 100% accurate, but they are the closest he could get within the limitation of his display gamut. I found those values to be really good for my display as well. If your display panel is significantly different that the one he has, you will need to come up with your own values using a colorimeter.
[Nexus 5 Themes and Apps] Cyb3rGlitch:
Is it possible to use this to completely turn off a specific colour channel? e.g. all blue subpixels? I can't seem to work it out.
[Nexus 5 Themes and Apps] 0rigin:
Why would you wanna do that? Try to put all blues to 0. That's a guess though
[Nexus 5 Themes and Apps] Cyb3rGlitch:
That doesn't work. And I want to do it as a makeshift RGB control.
[Nexus 5 Themes and Apps] rajendra82:
Values 1-12 are actually subtracted from the lighter colors and values 13-23 are added to the darker colors. So to set Blue to zero, you would need to set values 1 through 12 to 255, and set values 13 through 23 to 0. I think that would work by making blue intensity zero at every blue level. So the color white should look yellow.
[Nexus 5 Themes and Apps] GragonV:
I'm running vnir ROM with franco r30. After installing the N5 Gamma Cali, I've noticed that all of my settings are exactly the same with yours (even though I haven't adjust anything!?) except the white point (32 not 29)?!

And most of the results of my gamma test except the white and yellows one seem to be at 2.3 - 2.4 (not exactly 2.2 like ... eh... last week.. before flashing the new rom and kernel I guess). Is it good or not?

Any setting suggestion to get the color like the iphone5-profile in faux123 (on N4)
[Nexus 5 Themes and Apps] Cyb3rGlitch:
Perfect. Thanks! Unfortunate that it seems to tax the device to apply the settings, though.
[Nexus 5 Themes and Apps] t0m_t0m:
There is a setting to correct the yellowish effect? If I can avoid the exchange by the after sales service ^ ^
[Nexus 5 Themes and Apps] FlexiPack:
I would really like to get rid of my yellow tint but have a couple of Q's before I proceed.

There are so many settings, kernels etc that it's quite overwhelming. What is a good starting point for a beginner?

Does this app or adjusting rgb values via another kernel impact on the speed of the N5 at all? Is it more processor intensive?

Thanks.
[Nexus 5 Themes and Apps] magnamentis:
not that bad after all :)

hi,

there are 2 kernels working with this app, faux's and franco's while there are others with other tweaks to get rid of the yellowish tint.

you find absolutely all the necessary information in this thread, but you have to go through it from page 1.

i found at least 3 confgurations in this thread which where somehow satisfactory for me while if you follow the posts of mag01 you

will find the most sophistcated attempt there, at least as far as my opionion is concerned :)

faux and franco gave up on an initial tweak which was looking great ( franco r14 ) but they are both experienced

devs and thus we have to assume that they had good reasons to give up on that one ( not safe )

however, i'm quite happy with my settings ( mag01's ) and recommend them, at least well worth to try.

the kernel with the original franco tweak is elementalx i think but you have to look it up and verify and

decide for yourself if you wanna go there. franco's is my daily kernel, just switching to faux's from time to time

when extremely busy franco comes up with a small glitch, which is always corrected within hours by the way,

just one exception in years so far.

since flashing a kernel is a matter of minutes at max, just go ahead and try things out, nothing to fear, they are all quality builds,

just with different priorities.

Sorry. You've been brainwashed to think good color pops. It doesn't. The color reprod from this is close to srbg. Just gamma is off.

Thanks :)
[Nexus 5 Themes and Apps] droid@xda:
I am using this app on stock setup with franco's kernel.

I am only changing white point in settings but everytime I turn screen off and on, my custom gamma setting resets. I have set it to get applied on boot but still same results. Its irrespective of whether I keep gamma calibration app open in background or not. Setting just resets after screen turning off on. Modified value still remains in app but I have to again click on apply button and then it persists again till screen on off.

What could be the issue?
[Nexus 5 Themes and Apps] bornoxt:
Proper SuperSU and BusyBox installation?
[Nexus 5 Themes and Apps] droid@xda:
Yes. SuperSU flashed via TWRP and working fine for other apps. BusyBox too works for other apps.

Should I go with normal or smart install in BusyBox. I have currently installed it in normal way.

I'm also on the stock rom with Franco. I haven't installed busybox and my gamma setting stick without issue. After a reboot I see the settings take hold on my screen.
[Nexus 5 Themes and Apps] Ok_Kaleidoscope5109:
Does anyone get really weird colors using mag01's settings? I'm curious how many different types of panels are out there? Or I could just be doing it all wrong because I did try it at 4am in the morning while waiting in line at Tsukiji Market for some sushi :D
[Nexus 5 Themes and Apps] biggiephat:
No matter what I do nothing sticks
[Nexus 5 Themes and Apps] Ok_Kaleidoscope5109:
After playing around more it seems like mag01's Gamma 2.2 settings give me a reddish tint. I'm closer to Gamma 2.2 compared to stock, but comparing to a piece of white paper, my iPhone 5, and my computer screen, my Nexus 5 seems quite reddish. Shrug.
[Nexus 5 Themes and Apps] GUGUITOMTG4:
My settings for more accurate White & Black. Includes: 2.2 (Red, Blue, Cyan, Grey, Magenta) and 2.3 (Green & Yellow). G & Y @ 2.3 will help me reduce the stock yellowish looking!

RED:......40,50,60,70,75 80,90,100,110,115 125,130,125,115,115 85,65,50,35,25 20,15,10

Also. To keep the settings, press "apply" before changing from one tab to another, turn off-on display, open app and hit apply again, take Screenshot or write down your config, toggle off-on 'set on boot' and reboot. works every time with Faux and Chaos kernel on Cataclysm & Purity Rom.
[Nexus 5 Themes and Apps] ganeshp:
Same here.. Ultimately I was unable to remove the yellowish tint even following mag's values and his method.. So I went for the alternative.. Which is cooler color preset Introduced by franko.. Which is still present in elementalx kernel.. Atleast blueish white is bearable to me
[Nexus 5 Themes and Apps] droid@xda:
For me, values don't stick after screen on & off. ?
[Nexus 5 Themes and Apps] GUGUITOMTG4:
maybe you have to hit apply more than once as the app is kind of laggy when you press it.
[Nexus 5 Themes and Apps] AndrasLOHF:
I always hit the apply button on each screen and keep pressing it until I see the cursor pause for a second to make sure the settings stick. If I don't do so it almost always reverts back.

Hey [MENTION=3332811]faux123[/MENTION] , [MENTION=3292224]franciscofranco[/MENTION] jsut released r32 of his kernel and suddenly it's not compatible with this app any more. Multiple users have reported it on his thread. Any idea as to what happened there? Franco says no code changes were made by him, that he's still using your code as is.
[Nexus 5 Themes and Apps] aimetti:
yep same thing happened to me ,

nothing changed other than r32... so maybe I'm confused?
[Nexus 5 Themes and Apps] gpvecchi:

[Nexus 5 Themes and Apps] katsuru:
I got rid of francos kernel ( sadly had to... ) on my nexus 5. Nexus 7 still rocking his kernel and paid app.

ElementalX kernel still hast the code changes that turns my screen into a monster :D . People say it may break stuff this numeric change inside the kernels code which affects the color temperature ... I just don't believe that... Been using it since day 3/4 after I got my nexus 5, and running rock solid till now under extreme usage.

I just wish franco would keep supporting this app, as it is still really useful even if you got the cooler color temperature, I mean being able to adjust display color reproduction is just amazing, everyone has his own vision of what "perfect" color reproduction is, and to be honest this is what this forum is all about, opening the device to a point where the user is able to customize almost EVERYTHING according to his liking's..

I hope franco realizes that some of us ( maybe the most of us ) are whiling to take the risk of using apps like this and code that *COULD* break something, and implement back the cooler color temperature on a separate release of his kernel, or just inside his app and let us choose.

This is what I have been doing since my Motorola Milestone, taking risks! to achieve "perfection" :fingers-crossed:
[Nexus 5 Themes and Apps] Moh_Jay:
Franco won't put it back but you can use http://xdaforums.com/showthread.php?t=2538441 its everything franco kernel built with color patch and has dt2w etc. (Everything besides color patch is off by default but instructions (first post) on how to enable them if you wish to do so are there).
[Nexus 5 Themes and Apps] chikimonke:
That's the thing though, he not not supporting this app, it just suddenly stopped working with his latest update. All the code that would matter to this app working has been the same since mid December. Here's a link to his response to me, pointing me to the code he uses. To my untrained eye, all looks like it's in good working order to me. Can anybody see something different?
[Nexus 5 Themes and Apps] katsuru:
Wow I dunno how I could habe missed that!!

Thanks alot mate :good:
[Nexus 5 Themes and Apps] magnamentis:
will be back, i'm sure :)

exactly, of course something has changed, go back to r31 and all works again, not doubt on that end :)

hi,

franco is sometimes a bit quick with "nothing to do with" and "nothing changed" replies in a bit a flapsy way but usually things will be corrected within a quite reasonable period of time.

fast an busy means sometimes errors but still always go back to his kernel when things have settled a bit.

i know how i was at that age so nothing extraordinary so far. just wait a few days and this will work again.

I do his 2.0 for red and 2.2 for the others and it takes away most of the pinkish tint
[Nexus 5 Themes and Apps] Ok_Kaleidoscope5109:
I actually am not too happy about that attitude. Shrug. I respect the guy for his talents, but sometimes he plays the defensive game too much. It's just like when CM compatibility breaks with his kernel. He denies that it's him, but sometimes in the end he makes the changes anyway.

My point is that if you say your kernel is CM compatible, then you tweak for CM, not the other way around. CM is a full package, and it can do anything it likes. Changes that CM have made are primarily designed for CM to function better as a whole package. CM was never designed to allow for custom kernels anyway. You have to make your kernel compatible for CM. So I don't get his attitude sometimes.

Similarly when faux hasn't touched this app for weeks now, and r31 of FK works but not r32, then what does that tell you? Even if it isn't Franco's fault, and there's a bug in faux's app, his attitude is still wrong. He should look into it and conclude what the problem is. If he truly believes his own kernel isn't the issue, then the right attitude would be to notify faux (given that he's contributed in this thread too) that his app may have an issue and that faux should look into it further.

Ok sorry for ranting. I hope this does get fixed one way or the other soon!
