I can confirm this. Apon boot if I let the screen turn off:victory: the phone will reboot shortly after. I knew the app was the issues, but I don't know why I never bothered to report it.
[Nexus 5 Themes and Apps] chw2006:
I tried this just now and it somehow gets even yellower...

I flashed franco's r14 and it did indeed get rid of the yellow tint, so much so that it was looking blue. Is there anyway to replicate that using this app?
[Nexus 5 Themes and Apps] tkoreaper:
If it made it more yellow then common sense would dictate that you should do the opposite.

As for Franco's kernel that is because that version had his own color tweak applied. It has been removed in the newer kernels. I recommend that you use the latest kernels for stability reasons due to the latest 4.4.1/4.4.2 updates and they also include other countless fixes.
[Nexus 5 Themes and Apps] MoJo:
Same situation on Franco kernel since r14 up to r19. Will check with latest r20.

P.S. Have flashed Franco kernel r20, everything looks fine - no reboots so far!
[Nexus 5 Themes and Apps] tkoreaper:
Its the app, not the kernel.
[Nexus 5 Themes and Apps] MoJo:
Yes, I had read previous messages, but after flashing r20 reboots were gone, do not know the reason ...
[Nexus 5 Themes and Apps] tkoreaper:
Are you leaving the device alone apon boot? Let it set there for about a minute and it will reboot unless the kernel created some kind of workaround.
[Nexus 5 Themes and Apps] MoJo:
Specially after your message I rebooted devices twice and yes, I was leaving device alone upon boot during 3 min. - no reboots!

Yup, later today I'll test it. I'll try even another approach with Screen Adjuster app, as in my case, I don't need to touch the single color gamma curve, but just blue level and global gamma (so contrast/brightness should be enough)...
[Nexus 5 Themes and Apps] impulse101:
Well my n5 must not have been calibrsted correctly then because the default calibration is way off what it should be

I want some settings that are like the ones Franco always used in his Kernels until he stopped. Any tips?
[Nexus 5 Themes and Apps] Pretoriano80:
Using franco R19 or R20?I'm asking because on R19 i couldn't reproduce it, but now after updating to R20 i encountered the same issue.

I will go back on R19 and try again to reproduce the issue.

I had reboots with r19 and have not now using r20.
[Nexus 5 Themes and Apps] paddylaz:
Potentially slightly OT, but a few people have been reporting that 4.4.2 includes with it a subtle improvement to display contrast - which I'm assuming means the gamma has been re-adjusted?

(if there's any truth to this of course).

Thought it'd be worth mentioning!
[Nexus 5 Themes and Apps] tkoreaper:
It's not the Kernel's problem guys... It's the gamma app. If you have settings that it's supposed to apply upon booting then it will force your phone to reboot ONLY if you leave your phone to idle during the boot process. Just use your phone for a couple seconds immediately after it boots and it won't happen.
[Nexus 5 Themes and Apps] gpvecchi:
Ok, I started testing...

Values for Positive (I worked on blue) are actually all the greyscale points. Raising them, raises gamma (darker shadows) on all the scale.

The median value corresponds to 70% grey. Greyscale is reversed, so first value is 100% white. They seem not to be linear as first values are more sensitive.
[Nexus 5 Themes and Apps] mag01:
If you have a time, try to focus especially at:

- first 7 - from white to approx. the middle of the range)

- 11-15 (around 13) - around the peak value

- last 7 - down to black

how much does the change in some small range (+/- 1-5) affects the output and in which way (at the 13th value there's a turning point where the effect is reversed which is funny thing)

Then try to check the exact effect of changing the white point - that seems to be so called "gain" actually: http://www.qvolabs.com/images/Nuke_basic_CC_Gamma_GainMultiply_Offset .jpg.jpeg
[Nexus 5 Themes and Apps] gpvecchi:
The positive values actually affects in particular first graph; from 13 to up, a correction of 5 points are around 0.2 gamma, while on whites 0.2 gamma is around 3 points. I would't actually touch the white point as it effects just the lighter part of the graph...
[Nexus 5 Themes and Apps] mag01:
Yes, but the point is to find out what and how much each of these settings change the output so some simple decent app that lets you simply adjust the stuff could be developed. This may also include the gain (now white point) adjustment as someone might find it useful.

I'd expect the maximum acceptable adjustment range to be determined as well (perhaps not more than something like +/- 10).
[Nexus 5 Themes and Apps] gpvecchi:
I quit. There are too many values, all dependent each other; positive and negative sum their result.

139 values are too much, and every one acts in different percentage; and there is no way to adjust color level.

So, with every value you'll use, there will always be a lack of blue...

Standard calibration will always be better.
[Nexus 5 Themes and Apps] mag01:
Ok :D I'll try to do something about it once my colorimeter arrives. Yes it will be time consuming, but I'll try.

bah..srsly, i tryed every setup in this post, but i finally returned to stock calibration ( of 4.4.2) seems quite good default settings now!
[Nexus 5 Themes and Apps] paddylaz:
i keep hearing scattered reports on here of 4.4.2 improving the contrast a bit of the screen (which was really the only criticism - the gamma - that anandtech and others had with the display upon review).

Would be interesting to know if anyone can confirm that.
[Nexus 5 Themes and Apps] Ok_Kaleidoscope5109:

[Nexus 5 Themes and Apps] Ok_Kaleidoscope5109:
Right, that would get me back to stock calibration, but I want to know the stock values, so I can start my tweaking over...
[Nexus 5 Themes and Apps] JNewms:
He Just told you how to get them. After you turn off set on boot. Reboot it. Then take a screenshot or put the stock values into keep so You'll have a reference point.

[MENTION=4152171]myfluxi[/MENTION]

Gamma 3 is tricky. It seemed to be a command of sort where any part of the command sequence in Gamma 3 is wrong, the whole white point calibration is out of wack! So unless we know the exact command's meaning, any 1 bit error throws the entire white point off and you end up with bluish tint which I don't think its good in the long run since we have NO clue what its doing.

BTW, I wrote an email to Mr Devin Kim almost three weeks ago - no reply, nothing. No wonder JBQ left.

Yeah he didn't reply to me either. I asked Google if there's any direct contact to the engineering team or CAF/LGE and they told me the N5 Kernel has only one Google guy merging commits but all work is done by CAF and LGE so there's no direct contact. Sigh :)

Great work on this!

I've been patiently awaiting the update of FauxDisplay for my N5 to fix the horrible yellow hewed white.

I read earlier that this is really for advanced tinkerer's, but seems like the current settings are pretty dialed in?

Question is, is there much of a chance that using these settings could cause damage to the phones screen?

Or is this essentially an alpha build of what will become the new display app?

Cheers!
[Nexus 5 Themes and Apps] myfluxi:
Nice.

It would be a good idea to have a free app once the interface is stable and even if you merged it to your regular apps. This would emphasize the community approach.

Tbh, I'm not a friend of paid apps but I respect that. I had my extensive control app over 2 years ago (I think even before most others) and it was always free.

[Nexus 5 Themes and Apps] markwebb:
Am confused about this. When I installed the 107 apk I see the settings; when I install the 108 apk they aren't there except for set on boot and the web post screen. Is 108 already preset with those ideal settings?

[Nexus 5 Themes and Apps] fireproofrev:
Am I the only one seeing no difference when chancing any of these gamma settings?

I am using the newest 004 public beta provided in the OP and the new version 0.8 of the app. I set everything (on all tabs) at 255, applied, and turned the screen off and on again, -> no difference

Also I set every gamma value to 0, applied and truned the screen off and on again -> no difference

The values were set successfully. I closed the app completely and opened it again. it still showed my configured values but the screen looks the same with every setting.

[Nexus 5 Themes and Apps] italia0101:
Go over to gamma 5, change column 2 and 3 to 20 does your screen get darker?
[Nexus 5 Themes and Apps] Batfink33:
It does, that's a good test.
[Nexus 5 Themes and Apps] JNewms:
How isn't it? That's how all apps are. When you tweak settings, then set them on boot, that makes it so your custom settings will stick after a reboot. When you uncheck set on boot, It will make it so that your custom settings Don't stick after a reboot. It's a way to always get back to stock settings on kernel related apps.
[Nexus 5 Themes and Apps] Ok_Kaleidoscope5109:
It might be for kernel related apps, but I don't generally use any. Most apps I use, if you set something, and then turn it off, then the fields get grayed out. When you turn it back on the previous setting kicks back in. Either you remember the stock settings or back them up (which I didn't, so I'll take fault there), or there's a reset button in the app.

I'm not saying this method is wrong, it's just not what I expected, given how most UIs are designed.
[Nexus 5 Themes and Apps] tkoreaper:
It has nothing to do with the UI though. The app is tweaking settings that are hardcoded and unless the kernel is built with your settings it will always revert back to it's stock setting on boot. That is why the settings must be applied on boot... It's always been this way for things dealing with the kernel. It's not some file you're editing and then saving... Doesn't work that way.

Edit: I read more into your complaint and see where you're coming from. You want it to save your settings when you turn it off. The feature isn't included in the app although I'm sure it will be in the future. This is practically a beta of the app. What you want is a way to save profiles and such.

Everyone's display is different so of course no ones settings are going to work. There have been several posts in this thread, even a lot from me, on how to calibrate your display. I recommend you do some searching in here.
[Nexus 5 Themes and Apps] Ok_Kaleidoscope5109:
Oh... well I don't really care for saving the settings when I turn it off; not now at least. I actually wanted a way to go back to stock and to bring back the stock settings so I could start with a fresh set of numbers and tweak accordingly. I was assuming a standard UI where you turn off the settings and the saved settings stay, and so when someone told me to flip the switch on "Set at boot," it wasn't intuitive to me that the hardcoded settings would also return to stock settings.

32, forgot to add it
[Nexus 5 Themes and Apps] TrainNanpaMaster:
I've also tried every single suggested color setting on this thread. After hours of fiddling with this app, IMO, nothing compares to stock color with whitepoint of 27. 32 is WAY to HIGH, and the screen looks washed out.

[Nexus 5 Themes and Apps] ChazzMatt:
Agreed with whitepoint. Stock 32 is way too high. I'm also using 27, but haven't tried it with stock color calibration. Would be nice if that's all we end up having to change? :)

These are the settings I've been using.

[Nexus 5 Themes and Apps] NYCguy2020:
Same here. After trying so many different settings I've settled on stock color with 28 white point. Looks perfect on my screen.
[Nexus 5 Themes and Apps] TrainNanpaMaster:
Exactly. Sadly, all these suggested settings make the screen look weird in some sort of fashion. Something always ends up looking 'off'. I laugh at these people that are so hung up on trying to hit '2.2´ across the board. Even without banding, 2.2 looks like complete crap on the existing stock whitepoint. It's best to follow your eyes, not statistics of what a 'color calibration tool' tells you what you should do.

Gamma 2.4ish looks so much nicer.

I do want to note, that Franco's previous color hack, with a white point of 27 with this app, gave me the best, most beautiful color I've ever seen yet. Unfortunately, it simply would not stick after screen unlock, and Franco removed it anyway<.

Wut. Color calibration is about objective numbers. You could calibrate with your eyes to what you like but so what? People like over saturated colors of AMOLED.

[Nexus 5 Themes and Apps] Moh_Jay:
People are hung over 2.2 because it sets a proper standard by which to follow. Remember this is still a work in progress and finding the proper starting point will help make it easier for everyone in the end, whether they want more saturated colors or not. Also, screens vary from person to person so colors that are off to you may be perfect for someone else. The 100% certain way for you to get the screen you want is to play with the gamma settings yourself.
[Nexus 5 Themes and Apps] TrainNanpaMaster:
Yep, you're exactly right, can't disagree with you. There needs to be an established standard, so developers have something to

work from.

With that said, 4 of my buddies have an n5,

all of them have speculated that the color is a bit 'lacking', and the blacks look hazy grey at stock settings, and the screen has a warm urine tint. There's a certain point when subjectivity erodes and critical consensus materializes. I don't think screens differ as much as people are saying.

[Nexus 5 Themes and Apps] Ok_Kaleidoscope5109:
Sorry, I was typing on a mobile device so I didn't make myself too clear. My point was that Gamma 2.2 is an established standard. You're saying who cares, but just because you don't care doesn't mean others shouldn't. You might like Gamma 2.4, but what's the point? sRGB is approximately Gamma 2.2.

I used AMOLED as an example because it pushes fake and oversaturated colors. Your eyes might like it, but it's not necessarily accurate and not representative of what you see on a properly calibrated monitor. Basically the point of SRGB is so that when you look at a photo on a properly calibrated screen, it will look the same across all other sRGB monitors/screens (phones included). This is important when you print also. I see AMOLED the same as Beats audio. Earphones/earbuds that are "fun" to listen to tend to be boomy in bass and inaccurate. Audiophiles who appreciate accurate and balanced drivers will typically choose another pair.

faux i use you kernels on my device (N7)..i will give this a try in about 2 weeks.....that is when i get my N5......
[Nexus 5 Themes and Apps] ChazzMatt:
2.2 is considered the minimum "standard", but some movies were meant for 2.4. So 2.2 is not set in stone.

http://www.avsforum.com/t/1332660/gamma-2-2-vs-2-4#post_20386885

Even in the U.S., note it's not really 2.2 -- but 2.22.

Problem is, out of the box, these Nexus 5 displays seem to be set for 2.0 -- which is why the blacks are high and colors are washed out. :rolleyes: For me anywhere between 2.2 - 2.4 is fine. Anything LESS than 2.2 is unacceptable.

So, don't criticize people who might want 2.4. There's NOTHING wrong with that. 2.2 is NOT the definitive standard. Proper gamma can be in a range of 2.2 - 2.5. HOWEVER. 2.0 is definitely WRONG. So, this app is heading us in the right direction.

Understanding Gamma

http://www.chromapure.com/colorscience-gamma.asp

Basically a blend between 2.22 and 2.4, is the correct choice. But anything less than 2.2 is definitely off.
[Nexus 5 Themes and Apps] Ok_Kaleidoscope5109:
I agree. sRGB isn't necessarily Gamma 2.2. It's roughly Gamma 2.2. My point was that one should still calibrate to a standard rather than "Oh this looks good to my eyes" because quite honestly I like punchy oversaturated colors too. Unless you are trained in eye calibration like you're a professional photographer who knows to look for blown out highlights and shadows correctly, color banding, etc. I highly doubt many of us are suited for it.

My point is 98% of those "I tuned my screen to X Y Z settings and it looks great. Punchy colors, just like AMOLED" comments are pretty useless. At least for those seeking an accurate calibration.
[Nexus 5 Themes and Apps] Slimer777:
Stop assuming "Gamma" means Gamma. Remember the N4? The colour calibration did not turn out well. You need a Spectro to reverse engineer these parameters. And stop using that gamma testing software, you guys are seeing indirect changes affect the real gamma values only. And even if you find the real gamma parameters, software gamma testing is really not accurate at all.

Stop saying gamma this and gamma that, most of those parameters are not directly related to gamma.

When I was working with AndreiLux on his Perseus kernels we had great success because everything was systematic. I didn't dare to buy a N5 after my N4 experience...... Horrible screen. But I have a G2 and these parameters should work on it also. If someone can port this to the G2......then we can stop the guess work.:good:

Right. People want the option to go back to stock settings and have the app reflect the numbers for those stock settings. If you want to call it a "stock setings profile", fine. But fully REVERSE any changes made, including all the numbers settings. The option to start over from scratch, as if you had installed the app for the first time and not yet made any changes.

Right now if you UNtick the "set on boot" your Nexus 5 display will not act upon any modified gamma settings, but it will still show those settings in the app.

We would like the option to fully revert to stock settings, start from scratch. It doesn't have to a profile, just a setting you could click: "revert to stock".
