Franco hasn't implemented gamma yet, but will eventually. His priority is to get a stable release out first.
[Nexus 4 General] tonettothebest:
best configuration for an AMOLED display color lover?
[Nexus 4 General] resynx:
Try line 7 ;)
[Nexus 4 General] otariq:
Okay I just flashed faux kernel and am using the trickster mod app does that not support gamma
[Nexus 4 General] kwerdenker:
Gamma support is currently only achievable by using faux's kernel and his app (play store link)
[Nexus 4 General] DirkBelig:
It also works with the stock kernel.
[Nexus 4 General] kwerdenker:
You are right of course. I'm so used to custom kernel I forget about stock :o

Nub question but whats google and LG presets ? and how do i use the LG preset ?

PS: nvm i found it.
[Nexus 4 General] mrtraveler:
Hi everyone I just received my phone but was a little disappointed when comparing the screen side by side with my GNex. The colors look washed out of the Nex4 but on the GNex they are bright and vibrant. I want that on the Nex 4 but I don't have a clue how to do it. I've searched online and was brought to this thread but no where does it explain how to change the colors. I see the apps but do I need to root first for is this something that can be change while stock? If I screw it up while making changes can I return it to the stock settings easily, maybe reset the phone or something and try again?
[Nexus 4 General] kwerdenker:
Welcome to the world of the Nexus 4! :)

The difference you see compared to your GNex is in a large part down to the different screens that are used. GNex is a Super AMOLED screen, where as the Nexus 4 is an IPS screen. AMOLED has more vibrant colors but the newer IPS panels comer quite close to that. Using the apps in the first post you can however tweak the screen settings a bit, so you might be able to tune it more to your liking. Just don't expect too much of it because there are the mentioned differences in screen technology. (I come from a Super AMOLED device myself and I actually prefer the more natural colors of the Nexus 4, but that is down to personal preferences ^^)

Root is a requirement to do this, but you don't have to install any custom kernel if you don't want to. If you think you messed up your settings, there are multiple ways to get back to the stock ones: franco's apps have a "restored defaults" function and in faux's app you just untick "set at boot", reboot and you are back to the stock ones.

As a starting point, you might want to check out row 13 of the spreadsheet. The users comment says these values are meant to have a more vibrant AMOLED like look.
[Nexus 4 General] mrtraveler:
Okay Thanks. Getting to root right out of the box. I usually wait a month or two but this won't wait. :D

[Nexus 4 General] MasterJam882:
Hey all,

I hope u guys can help me out here:

I want to calibrate my screen and read all 24 pages here but still have some questions:

Is it enough to buy fauxclock to set gamma, gammaamp AND google/lg presets or do I also have to flash his kernel?

Don't want to flash a custom kernel right now and wanna stay on stock(rooted) for a while.

I'm tempted to buy the app but if it does not give me ALL these settings the price is too high for me.

Thnaks and greetz

[Nexus 4 General] kwerdenker:
If you really want them gone, that can be arranged (damn... that sounds like I'm a mafia killer :D ). I don't see any real harm in them staying in the spreadsheet though. They show your progress and maybe someone might prefers the gamma values these settings provide. The more choices we have, the better it is I would think.
[Nexus 4 General] undercover:
Deal. Let them live for now :D

Ok, then I just need them marked as recommended by me in remarks. :thumbup:

Sent from my fridge. Make:LG Model:N4
[Nexus 4 General] kwerdenker:
Done. I also added a reference to the third settings in the comments of the first two.
[Nexus 4 General] DirkBelig:
2.2 refers to the gamma point considered to be the standard for displays. Using the patterns in the Display Tester app, a properly calibrated display will have the colors blend at 2.2. See an example here: http://www.lagom.nl/lcd-test/gamma_calibration.php

Display Tester app is here: https://play.google.com/store/apps/...xLDMsImNvbS5nb21ib3NkZXYuZGlzcGxheXRlc3RlciJd

The free version has the patterns, but it's crashy and a bit of a PITA as a result because you have to wait for the splash/countdown screen to go away.
[Nexus 4 General] undercover:
It's crashy if you stay in gamma screen. Go back to menu, then switch to gamma control. That way it doesn't crash when multitasking.

Sent from my fridge. Make:LG Model:N4
[Nexus 4 General] DirkBelig:
Doing this doesn't totally prevent crashes, but it takes more laps before it does, at least for me. Good tip, though.
[Nexus 4 General] resynx:
I just switched back to Faux's kernel and these settings are absolutely gorgeous :highfive:
[Nexus 4 General] nexus444:
I have a problem. I have a faux clock with franko r28 kernel, I have only option to change color settings , but no gamma and amps. Can you help me how to fix it?
[Nexus 4 General] Michealtbh:
As mentioned many times only Faux and stock kernel support the extra controls
[Nexus 4 General] DirkBelig:
^^ This.

Considering that some variation of mentions that root is required and it works with ONLY the stock or faux kernels appears on nearly every single page of this thread, the fact that people keep asking...:rolleyes:
[Nexus 4 General] Uh60m Pilot:
Another thing that has been noted before is that every screen is a little different. I have tried every setting posted and most of them look like crap only device despite multiple people saying that it worked fantastic for them. Let them live OP let them live!

Sent from my Nexus 4
[Nexus 4 General] kwerdenker:
It's also not only the device (the differences in screens is not that large), it's also the perception of the person looking at it. How we see colors is psychological as well as physical, so everyone has different preferences as to what they see as the "right" settings. Some like the popping colors of AMOLED, others prefer cooler to warmer color settings (or vice versa) and others just want that industry standard 2.2.

At least we now have the possibility to tweak it to our liking :good:
[Nexus 4 General] HRodMusic:
Excuse my ignorance lol but how do u guys measure your screen calibration settings? Where do you get 2.x numbers?
[Nexus 4 General] undercover:
That was answered one page ago. Before you get flamed (people please don't, let's educate here) next time you want to ask something in any thread read at least last 5 pages. Takes a minute and will most likely have the answer to your question.

my bad im a senior xda member.. felt like a newb asking that question.. deepest apologies =D i should be setting the example lol
[Nexus 4 General] MasterJam882:
Yeah I tried these at very first but the values were worse then mine. Not much but enough to search for others and found mine.

greetz
[Nexus 4 General] undercover:
Thing is you get used to "wrong" look of it and then when you try better calibration it doesn't look good to you. I get that when I go back to my settings too btw. You need to give it a day and make sure you are getting gamma as close to 2.2 as I was, ie make sure it's not shifted too much on your display. Regardless, my settings (3rd ones) are a good starting point, from there it should be easier to calibrate your screen as well as possible.

Sent from my fridge. Make:LG Model:N4
[Nexus 4 General] vickedme:
I found your third settings to very good.
[Nexus 4 General] MasterJam882:
The thing is that ur settings gave me values in display tester which were not even that close to 2.2 as mine were. Red was at 1.8.

Simple as it is your settings were not gd for my display. Sry^^

[Nexus 4 General] resynx:
Every display is different so you just have to find the one that fits you :)
[Nexus 4 General] Jiia:
Is there any way to enable gamma control on Franco Kernel? Faux's app was so unreliable that I had to uninstall it.

Nope, faux is currently the only one who supports the gamma settings.

Its been now 2 days since applying the undercover's screen settings and I have totally fallen in love with the screen. The colors looks just too good to be true. I am on stock ROM with faux stable kernel.
[Nexus 4 General] khaltire:
Hi everyone. Been doing some testing myself and gone thru all the settings that people say are excellent. I'm kind of a display nut and I've tested most of the settings. the ones people seem to praise are the ones that boost the contrast like undercovers 255 255 255 20-19-19 and others. Sure this may bring it closer to gamma 2.2 but the colors aren't quite accurate. The blues are way too dark, not to mention the color of the whites changes and the brightness of the display decreases significantly. The other setting that many are praising is the lg preset 248,248,248 10 -7-5, 4-4-1 but if you actually compare his one to stock Google settings with no modifications its 99% identical. Yet people say its soon much better. I think there's some mistakes here in what people think is accurate. And before someone mentions it could be my phone, I tested all the settings on two phones, one nexus 4 with a yellowish display, and a rev 11 with a purplish display. Thoughts?
[Nexus 4 General] jayeshrc:
for some reason my gamma setting keep reverting back to some random setup with really high blues and i have to keep resetting it to get it back to normal.. am i missing some setting or something?
[Nexus 4 General] resynx:
As stated before, every display and set of eyes are different. How you perceive colors to be accurate may be off to someone else and vice versa. Testing on 2 phones or not, variations are from device to device. The best thing you can do is try out different configurations and choose which one you think is best. Or compile your own and share for all to use :)

Never had that happen to me before. Have you checked 'Set on boot'?
[Nexus 4 General] kwerdenker:
Do you use Superuser or SuperSU as root app? Faux control is known for having problems with superuser. If you are not using it already, switching to SuperSU (available from play store) might help.

[Nexus 4 General] khaltire:
I guess I just compared it to displays that are known to be accurate like the iPhone 5 and more accurately the iPad 3. Colors are nowhere near these with the settings I've seen in the thread. It makes it easy to compare when you have a point of reference which you know to be accurate and high quality. Not taking anything away from anyone as people have done a bang up job in this thread especially faux. The display even with the gamma is not accurate, you have to sacrifice other stuff so I think I'll stick with stock
[Nexus 4 General] resynx:
Agreed, I have heard people saying that the iPhone 5 is the most accurately calibrated. Although I've read people in this thread using the iPhone as a reference point and posted setups that got their phone's closest to their iPhone's / iPad's as they could.
[Nexus 4 General] Ace42:
Could you calibrate your nexus to your iPad 3 and post the values, I don't know anyone with that iPad yet. And if anyone has the iPad 4 can you also do a calibration.
[Nexus 4 General] idividebyzero:
I dont understand the point of comparing it to the iphone, it should be compared to a computer monitor that has been calibrated, the iphone is probably nowhere near correctly calibrated, the default settings on my mac suck. The iphone may be the most accurate phone but that doesnt mean its anywhere close to being correct, it just means all the other phones are that much worse.
[Nexus 4 General] Ace42:
IPhone is praised for screen quality and the ip5 has IPS like nexus 4 so it's a good comparison device.
[Nexus 4 General] javiges:
with the application of kernel faux good colors are achieved
[Nexus 4 General] Ace42:
Would be interesting if someone tuned it based on those new 4k TVs or the Sony Z's.

I have a questions for everybod but I think Faux is the one that will be able to answer the best.

I'm happy with my custom color and I don't want to change them again.

Is there a way to write my custom color and gamma inside android and make it persistent even if I uninstall Faux's app?

Thank you!
[Nexus 4 General] faux123:
No, unfortunately you can't do it because the kernel has its own HARDCODED values and will ALWAYS apply them if you don't have my app running.
[Nexus 4 General] HaMaHa:
I have tried many settings and while I can actually get many of them to get close to the 2.2 across the board I am having a hard time getting rid of banding that I notice on the Display Tester app. I noticed that some settings will change the white saturation, I cannot get anything to change the black saturation settings. Anyone have luck with this? I tend to look at everything and not just the gamma settings. When calibrating a TV or monitor you start with brightness AND contrast. While we all know how to change the brightness, I have not found anything to change the contrast. Maybe this will be the key to our displays?
[Nexus 4 General] Try4Ce:
My Nexus 4 is from the latest January 2013 batch and yes, it has the yellow display tint. In fact, I went with a friend to a nearby store and we both got a device from the new batch, as well as a fellow co-worker who showed up with a brand new Nexus 4 today.

All 3 devices are from the January batch and all 3 have the slight yellow color tint (warm screen).

I am the only one with a rooted device and just bought faux's app which is absolutely brilliant.

I tried "undercovers" display calibration settings. In fact, the display now shows way more vibrant and clear colors, the tint is as good as gone. Blue colors always were a little washed out, as well as reds, now they show up strong and clean.

Thank you alot undercover!

PS: Yeah, the grey isnt perfect now, it has somewhat of a blue tint to it, but hell, that doesnt bother me at all. Grey's still look better now, before they had a yellowish, bleaching tint on them. Not really bad, but noticeably since I am very sensitive to colors on a display (i am really picky). Now it seems way more natural :)
[Nexus 4 General] Try4Ce:
Oh and @Faux:

Is it possible to include a settings-save option for the calibration panel? So that I dont have to setup the calibration again after I swap the ROM for example? That would be totally wonderful :cowboy:
[Nexus 4 General] 0.0:
In his app, there is a backup and restore settings option. Does that work for the screen calibration as well?

Sent from my Nexus 4
[Nexus 4 General] idividebyzero:
that just makes it the best of the worst, it doesnt at all make it a good calibration guideline, the kind of screen doesnt have anything to do with calibration since its the same end goal for every display in the world. Unless theres some THX certified phone I would not use any phone or factory display setting as a benchmark, they are never any good, even Apple settings, the default color profile for my Macbook looks like crap compared to after its calibrated.

The only way to know if its calibrated as good as it can be is to compare it to a computer/tv that has already been calibrated, not another phone.

PS: I honestly think those that say that the iPhone's screen isn't that awesome didn't really pay attention or never used one. The iPhone undoubtedly has the best colors of any mobile phone screen out there. I do like the Nexus 4 more though cause android is fun and love the bigger screen.
