I believe blue was 1.8 in Stock. With this profile I have 2.2 across board with exception of yellow and green which are 2.3. I believe Guguitomt64 said this was to offset the yellow tint. Either way looks perfect on my screen :)
[Nexus 5 Original Android Development] imablackhat:
Stock is 1.8 across the board for me. What about others?
[Nexus 5 Original Android Development] yorici:
Perhaps their are certain batches of hammerheads with similar displays. If you could find out which batch it was and if this is actually true at all, you could automatically get certain profiles for that batch. This idea was one time earlier proposed in December, but nobody really responded to it. I have 1.8 too, but most people have 2.0 i believe.
[Nexus 5 Original Android Development] Usexy:
Thanks man, these settings took my screen from yellowish to a cooler white. Around 2.35 gamma across the board. PERFECT for me :good::good::good:
[Nexus 5 Original Android Development] Zorrich:
Just reverted to stock to check. I have 1.8 for Grey, red, cyan and Magenta. Seems like it is between 1.8 and 2.0 for others.

Not really up to speed on this stuff to be honest, I've just been using other people's settings and choosing which looks best to my eye, lol. What do you mean by white contrast?

---------- Post added at 11:30 PM ---------- Previous post was at 11:27 PM ----------

Glad it helped, I know it made a world of difference for me too :)
[Nexus 5 Original Android Development] yorici:
Second one in de DPapp, then 5 swipes to the left ;) It's not all about gamma. I check saturation, color balance, gamma, contrast and banding. All in the DPapp. Every step should be recognisable at white contrast, which it isn't. Compare to stock I would say.
[Nexus 5 Original Android Development] Zorrich:
I'll look over it in morning. I did try your settings (yorici2) and there was a red tint, so I think our screens differ a bit. Either way, thanks for info!
[Nexus 5 Original Android Development] Moh_Jay:
I don't know if its limited to a batch but my first nexus (310k) had the yellow tint and 1.8 gamma while my RMA 311k nexus has 2.0 gamma by default with no yellow tint. The 311k nexus is also NOT the newer version that contains less power button rattle and bigger speaker holes.
[Nexus 5 Original Android Development] Fluidification:
stock is 1.8 everything for me.

fun fact: 1.8 is the gamma intentionally used for old Macs
[Nexus 5 Original Android Development] yorici:
I'm totally aware of the red tint. My profile was just a test, but vomer took it up in the cloud and I didn't mind

---------- Post added at 04:40 AM ---------- Previous post was at 04:38 AM ----------

Aha, I realised that no display would be the same anyway as the odds are very slim. So it probably won't be useful.
[Nexus 5 Original Android Development] vomer:
both added to collection :good:
[Nexus 5 Original Android Development] cobyman7035:
still waiting for that iphone5 gamma setting! someone just make one and name it iphone5 and i'd prolly use it lol
[Nexus 5 Original Android Development] yorici:
We really appreciate that you collect all the profiles, but you have around 20 of them now. And this profile madness started like 3 (?) days ago. What are you going in one week with 60 profiles? :p Should we categorise them on something? Like what they are based on: stock, mag01,etc
[Nexus 5 Original Android Development] Enddo:
sounds a little rude
[Nexus 5 Original Android Development] vomer:
Good idea! But I would have to rely on the poster to tell me what their base was. I don't mind putting them in folders on d-h.st :cowboy:
[Nexus 5 Original Android Development] yorici:
Increasing the whitepoint lowers the color temperature (yes, seems no noninitiative). So do you mean that by cooler colours?
[Nexus 5 Original Android Development] SeanHacker:
Sssshhhhh... :victory:

<tiptoes back out of thread>
[Nexus 5 Original Android Development] neriamarillo:
This I believe is true. There are some different batches of displays. There are some that complain about a yellow tint and some about a red tint. And to some the settings vary way to much.

Also weren't we trying to set up the gamma and color calibration with the white point at 32 that's stock?
[Nexus 5 Original Android Development] yorici:
But there are probably differences between phones within the batches. And yes, I try to maintain 32 as whitepoint. The colour temperature is perfect on the nexus 5's.

I imagine an app like this:

It starts with stock options.

It displays the DPapp tests and asks for the result

According to the result, the app changes the values and displays the DPapp tests again

User input -> fine tuning -> tests -> user input - - > perfect

This cycle will run for probably 5 times and then the gamma is perfect. Wouldn't such an app be amazing?

There are some catches though: Besides gamma, contrast, color balance and saturation are important too. These should probably be prioritised.
[Nexus 5 Original Android Development] neriamarillo:
Something that checks how you see the screen and test what build your screen is and then adjust and calibrate hmm that sounds like something good there. That way you would only need a handful of calibrations for different types of setups (ex. 2.2 across the board, cooler colors, warmer colors, saturation, etc).

I also agree about the contrast since it is affected by brightness which is really important and color balance and saturation need configuring too.

A bit demanding aren't we? Try loading up a profile that you like and then modify it to your liking. The only one that can make that possible is you and your eyes.

And YOU! Get back in here! Lol!!
[Nexus 5 Original Android Development] detdett:
How about you make your own and share with us
[Nexus 5 Original Android Development] blueren:
Hello! Would like to have some explanation over this: (yes, its a CM commit and has got nothing to do with FK, but i'd like to know since there are people here who know about what it does)

http://review.cyanogenmod.org/#/c/57452/
[Nexus 5 Original Android Development] yorici:
I actually didn't mention the build checking though ;)

App launches

Two modes: Idkwtfimdoing and expert

Exportmode contains the original faux app + sliders like my formula or rajandra's formula

Beginnermode:

Asks the user what he wants to achieve: cooler, warmer, accurate, oversaturated (lg g2 (horrible xD))

User selects, lets say accurate

Objectives: 2.3 gamma, color balanced and oké contrast+saturation

App displays DPgamma charts, asks if the whites are okay (no tints)

User replies with gamma results and color balance

App increases gamma if gamma too low and changes color balance accordingly

App displays DPgamma charts, asks if the whites are okay (no tints)

Etc, till display is 'perfect'

No serial numbers are needed now as the app automatically adjusts the values.
[Nexus 5 Original Android Development] cobyman7035:
yes that cooler look
[Nexus 5 Original Android Development] neriamarillo:
Yeah this makes sense. It forces the user to actually see and set what they like and calibrate it for their eyes so everyone would be happy!
[Nexus 5 Original Android Development] yorici:
Open the app and adjust it then?
[Nexus 5 Original Android Development] FuMMoD:
Amazing preset!! Than you so much for this, no more red tint.
[Nexus 5 Original Android Development] Fluidification:
So I have a 311k white Nexus 5 32 gb from back in November. IDk how i got a 311k back then, but it is. It has had no yellow tinting or anything, nor any build flaws, unless you consider small speaker holes a build flaw. (so yeah, mine has the small holes) I've been able to get all colors in between 2.2 and 2.3 and maintain a 32 white point.

Just thought I'd point it out there that my first config is probably pretty good for a white nexus 5 from november.
[Nexus 5 Original Android Development] yorici:
How is your white contrast? Mine is not that good on his preset. It's located in the displaytester app

---------- Post added at 05:49 AM ---------- Previous post was at 05:47 AM ----------

Yeah, differentiating in serial numbers is not going to work. What do you think of my app proposal 3 posts earlier?
[Nexus 5 Original Android Development] FuMMoD:
I downloaded the app but I can't figure out how to use it to find out what you're asking.
[Nexus 5 Original Android Development] neriamarillo:
At least for me this setting throws my colors almost to the 2.6-2.8 area and gamma is at 2.3-2.4 plus it looks really greenish-blue in my screen.
[Nexus 5 Original Android Development] yorici:
Open the displaytester app, take the second one. Swipe five times. Voila. Every brightness step should be roughly equal
[Nexus 5 Original Android Development] lndeed:
The 3xxk denotes the month the device was produced. Your device was made in November so it actually makes perfect sense that that's the one you got.

The more you know.
[Nexus 5 Original Android Development] cobyman7035:
Using droid xda settings seems pretty good
[Nexus 5 Original Android Development] rajendra82:
There is another, and a relatively cheap, way to set color temperature and gamma without the need for a colorimeter, and knowing the ins and outs of ColorHCFR or Calman software. You can acquire a set of Red Green and Blue filters. I have mine from my old Digital Video Essentials DVD. Amazon seems to have the DVDs still on sale, and you can also get sets of filters for around $10, but I can't vouch if the other ones are accurate. What you do is look at the standard test patterns from the display tester app through the filters instead of the naked eye. This allows you to judge the relative values of red green and blue, and adjust them correctly. For example when you are look at a pattern where green and yellow and cyan are next to each other. You can't tell anything with a naked eye, but when seen through a green filter, they are supposed to look the same, because the green filter cancels out red and blue, and yellow = red + green and cyan = green + blue. If they don't look the same, then the colors are not in proportion to each other. You can also judge individual colors by comparing them to white while looking through the filters. This can get you pretty close to neutral whites pretty quickly. Of course a colorimeter is the best, as it is way more sensitive than the eye, but it can take hours upon hours to take measurements and interpret them properly. The patterns also go through full bright colors to black, or you can make your own using gradient generator tool in the app. These can help you judge inf the colors are in proportion at one level, but not so at another.
[Nexus 5 Original Android Development] 1stx2:
Ok, how is everybody changing all the values? I joined the community, downloaded the updated version of franco kernel and color control is now in the app. I downloaded one of the files in this thread and there is alot of numbers. the color control section in his app only has 13 different places to adjust. What the heck am I doing wrong? Sorry if I'm asking a repeated question.
[Nexus 5 Original Android Development] yorici:
Super nifty!! Simple yet effective. One question though: how are you going to set gamma with these filters?

Could a camera be used too? I know you could take a picture of your screen and measure contrast ratio, but if I were to take a picture with a canon d50 and remove the green? Would that work? Or is it a case of try it out yourself? :p if the camera works, alot of people wouldn't need to buy filters:D
[Nexus 5 Original Android Development] Web_E:
Yes it is a repeated question. Read - http://xdaforums.com/showthread.php?t=2532422

Your answer is here -

When will colour controlz ariivez?

THEY HAVE ARRIVED on 14/1/14!!

Download the file to your phone, use file editor to remove the .txt extension and place the file in Franco kernel updater/colour profiles. Then using the Franco app you can import settings. Turn the screen off and on to successfully load it.

Here is all the profiles (I think and will try to keep updated) all the colour profiles posted in Franco's threads https://www.dropbox.com/sh/izp5dwyxl73xlt2/wehHWcJdQE

Hello [MENTION=4809179]yorici[/MENTION]

I am using v2 of your color profile, and I must say it is perfect! Every color is between 2.2 and 2.4. Just one problem is that I am seeing a very light tint of red over blacks. For example in the background of the Franco kernel app. You may not have this but can you recommend a solution that doesn't really effect the gamma levels of the colors?
[Nexus 5 Original Android Development] 1stx2:
Thanks man. I called myself looking through this thread, didn't even think of that thread and I'm subscribed to it! I feel retarded now.:good:

Franco can you make it so the colour profiles are in an alphabetical order when loading the profiles within the app? In my file explorer they are but within the drop down selection box I think they get displayed newest last
[Nexus 5 Original Android Development] Stylez Ray.:
So has anyone encountered following problem like I have it with only this kernel (running completely stock settings):

When I have my phone on charger and it's sleeping for like an hour it's really hard to wake it up, I press the power button and it takes ages for the screen to show and if it shows up it's slow as hell, kinda like it's running at a very low frequency and with no memory left. It first seems like an SOD but as the screen shows up it's not like it. I have to hard reboot to use the phone again.

Without charger it sleeps and wakes up with no problems.

Reboot your device. This fixed it for me.

Also you won't receive the beta immediately after joining. So just try again.
[Nexus 5 Original Android Development] Chad_Petree:
Already rebooted it a couple of times, the betas should show up right on the FK updater tab, right? :(
[Nexus 5 Original Android Development] apex84:
What's the reason for the voltage increments being 25 mV? Is it some hardware limitation or just for convenience? Would changing the voltage by more or less than this increment make it more unstable just as a result of not keeping with the +/- 25 mV steps?
[Nexus 5 Original Android Development] :
No, they come with Play Store app updates. Go to FKU in Play Store and look if you can press the update button.
[Nexus 5 Original Android Development] Chad_Petree:
Yes, just happened now, and now what? It updated the app, but nothing happened, no prompts that a kernel was installing or that I needed to reboot my device
[Nexus 5 Original Android Development] big_adventure:
There is no kernel involved. It's just the FKU app which lets you plug color changes into the existing kernel. The existing kernel has had the color hooks for a long time.
[Nexus 5 Original Android Development] Chad_Petree:
Oh OK, silly me, Thank you :D:p
[Nexus 5 Original Android Development] yorici:
Hi, thanks for using my profile. Though it was just a testversion:p. I wanted to show everybody that gamma 2.4 is easily possible. I am completely aware of the reddish tint. This is fixable, but will affect gamma. I'm waiting for franco, or anyone to implement my formula in an app. So everybody can tweak it. I already thought of an app idea a few posts earlier. If you can find anyone to implement it, go your game
[Nexus 5 Original Android Development] big_adventure:
My pleasure. :)
[Nexus 5 Original Android Development] Stevemeister:
It's def. not a hardware limitation because you can set the voltage manually per cpu step. Hopefully Franco will add +/-10mV and +/-5mV in the future.
[Nexus 5 Original Android Development] rajendra82:
The filters are a more direct way to measure what the screen is trying to display. A camera is going to apply correction for exposure, introduce color distortion due to what sensors it uses, etc. Them you are possibly going to look at the imager on a computer screen, which adds it's own calibration issues. I am not saying it is definitely not going to work. Just too many variables in the mix to get it done reliably. With filters, it's only if filter shade is standard, and how well trained your eyes are. Much more direct, if you ask me. And the last time I looked, the filters were way cheaper than a Canon D50. :)

PS - The gamma test patterns already give us a way to reliability test gamma. The filters help a little bit in this too. You can see if you are getting cross talk between colors by looking at the secondary and gray gamma patterns through filters instead. But without filters or colorimeter, there is no reliable way to measure the color temperature.
[Nexus 5 Original Android Development] yorici:
I already have a canon :p but i get the point. I'm going to buy some filters probably. About the color temperature, i keep that at 32, so it remains 6500K. Mag01 said that it could be a little bit varied though.
[Nexus 5 Original Android Development] elnahir:
OK, here's an issue I've been having with the kernel (finally, I found one!).

When the phone is charging via USB (I don't have an adapter that's EU-compatible) navigating it is almost impossible. What do I mean by "impossible"? The touch sensitivity gets completely messed up. I'm swiping the screen and an app decides to open (?). I'm trying to close the app, but instead a couple of menus pop up. It's kinda random.

I haven't observed the issue on stock kernel or whatever Cataclysm uses for stock.

Does anyone have an idea of what might be going on? Is there a log I could share to shed more light on the issue?

Anyone else experiencing this?
[Nexus 5 Original Android Development] Fluidification:
I like the app idea
[Nexus 5 Original Android Development] vs0587:
It's appened to my girlfriend LG P970... It's the usb cable/charger, not the kernel!! In fact, swapping the charger from an Asus (of my tablet) with another (of my old LG P990), the problem is gone!!

Incredible but true...... :eek:
[Nexus 5 Original Android Development] rajendra82:
The color temperature depends on the panel you get. This is probably why some users complain of reddish whites with mag01 settings. The whitepoint setting is unfortunately labeled that, and isn't really meant for color temperature control. If you read mag01 testing posts in the gamma control app thread you will see what he says. That number is a combination gain and gamma control. Dropping it below 32 raises gamma at the expense of maximum brightness, while putting it higher than 32 makes this display brighter, at the expense of gamma. Unfortunately our panels have a limitation on how high the red can go and how low the blue can go. Changing white point blooms the reds or crushes the blues. This results in a variable color temperature at different levels of intensity. Since we already have control over individual color curves, it is better to leave that setting at 32 and adjust the color curves instead.
[Nexus 5 Original Android Development] malinois16:
Nope, you can get away with a Ninja move like that :highfive: ! I asked via PM a while back but you never answered back, so I'll try again. :D Are you getting a nexus 5?

This filter set is what you mean? They do not really say on the original Lee site in RGB terms which color it is..

Franco, how long should it take for the max CPU to ramp back up after being throttled? It looks like mine has gotten stuck at 1190mhz. If I change the value manually it sticks so perhaps there's a bug in the code?
[Nexus 5 Original Android Development] Rxpert:
It'll stay throttled til it gets back below the threshold temperature.

Its not based on time, so there's no correct answer to that question. It'll depend on the environment the phone is in and what you are doing with the phone.

If you're manually trying to override the throttle I wouldn't say that's a bug in the code, that's bordering on user error ;)
[Nexus 5 Original Android Development] rajendra82:
The ones I have came with the digital video essentials DVD, which is discontinued, but still available on Amazon (at least in the US). I know that those are the reference red, green, and blue.

You can get the filters by themselves, but you will have to do a little research to make sure you get the right shade. The codes next to the colors on the site you listed probably tell you the right shade. You only need reference red, green, and blue to calibrate, but having reference magenta, cyan, and yellow will probably help too. Shades like Congo Blue, Vanity Fair, Blueish Green, etc. are not what you are looking for. I was thinking something like this, if the shades are right.

[MENTION=3292224]franciscofranco[/MENTION]

Is it possible to set a low battery mode in FKU? I believe not but maybe I'm missing it.

I would like to set a treshold battery level, below this value you have a specific low-battery-mode. It's something like per-app mode really, but it's triggered by battery level.

I'm ignoring FKU implementation, but analysing from outside, I suppose that such a feature should be easily implemented using per-app mode implementation.
