I've seen many Youtube Note videos with max brightness (some about e-reading), but almost none with the lowest brightness setting.
So, what do you think of reading at night with the Note, with low or no exterior light? Are white letters on black blackground too bright that becomes unconfortable?
What is your experience with apps like screen filter?
Those who come from HTC phones, do you find Note's screen more stressful to your eyes?
I've owned htc and sony phones and the Note's screen is very vibrant and great for night reading. Even on the low brightness in a dark room, you won't have trouble to read unless you have a bad eye sight.
Only people who are used to smaller screens or have pain in the eye will find the night usage painful for their sight. I use it every night before sleeping - no complains so far.
My fear is that Note will be too vibrant and brightfull and will strain my eyes.
For instance, I prefer reading at night with my HD2 than with my Asus Transformer, because it has a lower brightness level.
I don't know about you but I've also own a HD2 and I found the amoled screen very pleasant compare to every htc phones. The brightness can be toggle to suit you. But it's better that you test before in a shop if you are afraid.
There's an app called screen filter on market where you can lower the brightness until the letters are almost invisible. Great for night time reading!

Yep, I find it easy to read at night but only with screen filter. Must have app.
It is pretty bright at night, even with white text on a black background, but no problem if you use Screen Filter or one of the other several similar apps to dim it further. I have toggles on my home screen for several different filter levels for different purposes. Also, I use the night-vision mode that comes with Chainfire3D to turn it to red text on a black background, for even better night time reading.
With Fbreader you can just change the color of the text to something closer to black and have night mode with the lowest brightness setting on. Voila! Very clear and easy to read in pitch dark.
.....
My experience is a little different to others in the thread.
I also come from using an HD2 and to me, reading at night is a weakness for the Note. Even with saturation and contrast adjusted, the pentile display really stands out to me when you're (a) in a dark room and (b) holding the Note quite close to your eyes.
Both these are true when I'm reading. It's not particularly uncomfortable but just a bit annoying.
Could you detail further the 'pentile experience'? You see pixels or 'grain'?
I've had lots of other phones and can with certainty say that I've never had a book reader as good as my beloved Note. Pentile or not.

I can see the separation between the pixels as I tend to hold it quite close on a low brightness when reading. It doesn't make it any more difficult to read, and of course the resolution outweighs that negative, but it just makes it look a little bit less perfect.
I am using Screendim application and it works much better than screen filter. There is Screendim trial just for three days.
Amoled screen cannot be made lower brightness than the default so it must be using contrast features to make it dimmer.
I have to say that reading is the primary reason why I bought the Note. I read a lot of ebooks. I find the Note to be a perfect size for reading at night in bed.
I have never found the brightness an issue... What u need is a good reading app. Thats what makes the difference.
I use Moon Reader Pro and epubeader (free on the Market and can also read .mobi). Both these programs have the ability to change the text color and background and brightness.
I find that black background with pale grey/blue text is the easiest to read while conserving most battery power.
For me, Note is amazing, and if talking about brightness, it can auto-adjust itself.
I agree with documents transformed to pure black backgrounds and maybe 10% black to white text color is perfect for the eye, so you can almost fall asleep while your phone saves battery.
For some reason ScreenFilter worked better on my S2 than it does on the Note. Using ScreenFilter just makes the picture look bad... washed out and difficult to read. I wish my Note could have lower brightness on the lowest setting.
Maybe Samsung doesn't want to go lower to avoid showing imperfections.

I find it better if you use the Voodoo screen tuning app - worth trying
Hey everyone. Since faux123 has implemented gamma controls with his most recent beta kernel and app, I think it'd be good to keep his thread from being flooded with color and gamma numbers. Post the here instead!
Please post which ROM and kernel version you are using. Please provide a few comments about your setting, such as whether you aimed to achieve neutral colors or punchy colors. Also mention if you have experienced yellow tinting when on stock.
Try to adhere to the format below.
Code:
r[b]XXX[/b] g[b]XXX[/b] b[b]XXX[/b]
r[b]XX[/b] g[b]XX[/b] b[b]XX[/b]
r[b]XX[/b] g[b]XX[/b] b[b]XX[/b]
Below is a post I made in the faux kernel thread about how to reference your gamma adjustments.

I used this tool and have gotten color around where I want it. I recommend you save the image and view it in an app that will display it 1:1 scaling. I used Photo Editor for this purpose. It's important that you view the image 1:1 so the pixels of the image coincide exactly with the pixels of the screen.
Now, everyone's display is a little different from the next, and everyone has different color preferences. I personally dislike cold color temperatures.Your mileage may vary.
I suggest you leave the colors at 255, and only adjust Gamma Amp Adjust 0, one slider at a time. As the site says, aim for 2.2 in each of the firsy four columns. The remaining columns should fall in line. Then, adjust the color by lowering them one by one until you achieve a neutral color representation. I suggest that you keep one of the sliders at max and lower the other two accordingly (i.e. keep Red maxed and lower Green amd Blue).
I am using r255 g250 b245; r7 g13 b31. Note that this setting is for punchy, but accurate color. I came from a Galaxy S and used Voodoo Kernel, and this appears very close to the preset for "Punchy." Also note that I have had no issues yellow tinting, so the setting for your display may be different.
I'm not sure how Gamma Amp Adjust 1 affects the gamma other than reversing the effect of Gamma Amp Adjust 0.
Even with the the blue gamma maxed, the best I could get for blue is 1.8, no where near the 2.2 target. I have no iea what this means, though.
EDIT: After some consideration, I decided to have all three color gammas set to 1.8 (r1 g3 b31) and the colors to r255 g241 b255. I'm not sure if the color is better or worse from having 2.2 for Red/Green, but if one color is off, might as well have the other colors equally off.
EDIT 2: r228 g213 b200; r13 g9 b31; b7 yield the best colors for me. It's a tad shy of neutral (a little warm) but the gamma appears to be on point.

I'm on ParanoidAndroid BetaSEVEN and using faux kernel 002b5.
Code:
r[b]228[/b] g[b]213[/b] b[b]200[/b]
r[b]13[/b] g[b]10[/b] b[b]31[/b]
r[b]0[/b] g[b]0[/b] b[b]7[/b]
I have found this setting to be punchy and the colors appear pleasantly saturated. Dark greys tend to have an olive tint, but light grey and other colors appear fine.
I never had a yellow tint on my display, nor have I seen any dead pixels.
Stuck with more basic settings.
247,241,252-0,0,31-0,0,16
The colors I find, have solid whites and solid greys. No tints at all, which is what I've been striving for.

Well I certainly feel silly. All that time wasted using gamma calibration tools and I didn't just opt to pick which looked best to my eyes. It's not a punchy as I'd like it to be, but I got to admit, it's better than my settings.

What about Gamma amp adjust 1 red and green? Just 0 I guess?
I created a thread a few days ago with a public spreadsheet for this. Would be awesome for everyone to input their values

As post above states there's already a thread (by Ngo93) with a Google Doc that allows everyone to share their settings together so it's all maintained together rather than having lots of individual posts to check.

Both reviews and measurements have shown the HTC One to have a cold color temperature. This is something that should be correctable in software. Do custom ROMs ever include improvements to color temperature?
You'll have to wait until custom kernels are developed and have the screen calibration feature implemented.

What do you mean by color temperature. My physics background is messing with me here and I have seen some reviews and mention great color reproduction. So can you describe what you mean?

Yes, whites are 7800 Kelvin on the HTC One which is pretty cold. I believe it was done purposely to make it look brighter. Daylight is 5500-6500 Kelvin and 6500 is about the temperature of an overcast sky. Colors should be a bit more accurate if the temp is lowered closer to daylight. It should be easy to fix, someone just has to do it.
There is actually a spec for that. Look up CIE D65. Can't post a link since I'm new here.

Colour temperature is one of the measures of the colours a screen produces. If you set a particular pixel to be red 255, green 255, blue 255 the question then is, how much actual red, green and blue light is that pixel emitting? Different screens will produce different relative amounts; so, while you're telling the screen "white, please!" in each case, what you actually see varies from display to display.
Strictly speaking, the more useful measure here is "white-point". There is an internationally-agreed standard for display devices (e.g. televisions and monitors) called D65 which defines the exact ratios of red, green and blue that white is supposed to contain.
(I'm saying "white" here, but the same applies to any other point on the "greyscale" - that is where the logical red, green and blue values are all equal. So a pixel that is red 67, green 67, blue 67 should have the same ratio of red, green and blue light as a white pixel).
"Colour temperature" is a less precise way of measuring white point - it ignores the green component, and looks only at the relative amounts of red and blue light (so a screen can have the correct colour temperature but still be too purple or too green). Colour temperature is measured in Kelvins, and says that the balance of red to blue light is the same as would be emitted by a black-body at that temperature. D65 is approximately equivalent to a colour temperature of 6500K, and people measuring white/grey accuracy tend to measure colour temperature rather than white point, because there is no easy way of writing down a white point as a single number.
So, if a display has a colour temperature of 7800K, that means that a white or grey pixel is emitting too much blue light and not enough red.
The terminology is made more complicated by the fact that when people talk about adjusting the "white balance" or "colour balance" of the screen, they usually use the word "cool" to mean "more blue" and "warm" to mean "more red", which is obviously the opposite of what the colour temperature value is doing - a higher colour temperature means the display is more blue.
My own HTC One has a white-point that is visibly pushed towards the blue, and a couple of reviews have noted this: one at tweakers.net and one at uk.hardware.info ; but relatively few reviewers bother to measure colour temperature, and there have also been one or two contradictory reviews, notably one at computerbase.de.
A larger number of reviews measure maximum screen brightness, and most of those seem to come up with numbers somewhere around either 385 or 485 cd/m-2 but with nothing much in between those values. This suggests HTC may be using at least two different displays on different One handsets. If they are, it's possible there may be differences in white-point as well... but evidence for that is still mostly speculative.
Did anyone figure out how to make an adjustments to color profile on HTC One?
I have 2 HTC One's and one of them has nice cool bluish screen, and another one became much warmer (yellowish) after the firmware upgrade. And that drives me nuts, as that colder look is what I really love about HTC's screen
Phone is rooted and runs custom rom if that matters. Please share your knowledge if anyone know how to make the adjustments.
Resource exists to calibrate the colors of the Moto X 2014 screen?
Leave the most accurate colors, such as white IPS Display. There is possibility? With which resource?
I thank for the help.
I am sure a future modified kernel will allow for color calibration.

Moto X never really got a whole lot of dev support like most Flagships so probably just no one cared to do it.
Sorry for reviving a thread, but I am quite interested in this subjust considering my screen has the yellow tint. I think out best hope is that faux already has a github branch opened for creating a kernel for our device which most likely will support screen calibration like his kernel for other devices, I also believe he has an app on the play store for doing so for devices that support it.
If you search for screen adjuster in the play store, you will see several apps that can adjust tint, white balance, etc. Not as good as if you were able to do at the kernel level, but...
Any developer interested in creating this resource?
The screen colors " Moto X " are horrible When I compare with other models: Galaxy S5, LG G2, Sony Z3 / Compact...

I use CF Lumen to fix the colors. Works pretty well. I adjusted the color temp so whites are actually white now.
But it is the same thing as a kernel with this feature?
Have you used Color Control in a Kernel on another smartphone? It works the same way with this CF Lumen application?

Wow. Good find! This is the ONLY app I have found that actually *decrease* RGB channel levels with respect to base levels. All other apps only increase levels. By increasing channels, you wind up removing those inky black on AMOLED screens. So, when your brightness levels increase, the blackness takes on the color of the increased color channel, which of course is bad.
I do question your method of removing the yellowish whites of the Moto X. The color temp adjuster slid all the way to the right at 6500 is essentially no filter at all, as its the default color temp. Moving it to the left warms up the white balance, but doesn't result in whiter whites. What I found to improve whiteness was to keep the white balance at 6500, but in the color channels, reduce both RED and GREEN channels to 0.949 and 0.937, respectively. I just keep these settings around the clock and don't make use of all the other filters.
So, this is the only app that I've found where you can maintain your inky blacks while actually *raising* the color temp, or at least raise BLUE levels with respect to the other 2 channels.

I misspoke, I didn't mean color temp. I adjusted the master filter, decreased red and green like you said you did. And same here, that setting stays permanently without anything else. It makes a HUGE difference, my screen is gorgeous now. I'm glad you found as much success with it as I did
Thanks @_MetalHead_ for mentioning CF Lumen. This works so much better than Screen Adjuster Pro (I had been using that until now).

Try CF Lumen. It works wonders.
CF.Lumen has the nasty habit of applying its filters twice when rotating the phone and on the recent-apps screen. So if I calibrate my screen to look just nice, I get a blue tint on those occasions. So I'm constantly reminded of this workaround solution.
I'd rather stick with the yellow tint, trying to get used to it and still hope for a custom kernel to adjust the colors on hardware level. But it looks like nobody is interested in developing for the Moto X 2014... :crying:

It might be less noticeable if your filter settings are very low.
Everybody talks about removing the yellow tint, but what about toning down the saturation? I find it ridiculously fake, the google music app and tapatalk app look so cartoony with the stock saturation, could I tone it down with cf lumen?
Hello everyone ,i recently got a z3+ and i noticed that the black levels of the screen are pretty bad...coming from an oled display i was expecting some diffrence but not that bad...I watched some movies and in the dark scenes it is very difficult to see the picture ,everything looks the same and you cant really see the characters or the background ..its a mess especially in daylight conditions its almost unviewable.Cranking the brightness all the way up helps a lot -again in very good lighting enviroments/outside/daylight i cant see a thing in dark scenes- but then the black levels are too bad almost grey not black..
I also had a z1 compact which i dont think it was that bad, i'll try to test them side by side...
So i was wondering if a have faulty screen or something but i would like to hear your experience ...
Overall its nice screen bright with nice colours etc..but the black levels are a dissapointment in movies/videos..
Also i have disabled all screen enchanments (x-reality etc) and my white calibration is 178/162/37 RGB
Based on this review i was expecting more...
Blacks are pretty good in my opinion contrast ratio is brilliant for a ips. But this may come from you're eyes trained to a OLED screen. It's like my TV I have a lg OLED in the living room but a led in the bedroom and now I'm seeing grey instead of black :silly:

Here are some photos of my screen's blacks ...taken at 100% brightness in a 100% dark room ,all screen enchanments off, showing the same black level block picture in all 4 photos...i tried to adjust the camera exposure to make it look as close as what i was seeing ...as you can see it actualy can lit the desk under it and there is massive light bleed (if thats the correct term) out of the 4 corners in low viewing angles ,it actually creates a shape of X of light in a surface...Thats all please try it too to check out your results so as to know if i have problematic screen...
