Awesome Color Calibrator from the Nexus Forum! - EVO 4G General

This allows you to adjust the RGB Screen Colors. Check it out. Works on my EVO:

What are your settings?

I only got Force Closes when trying it out...

This has been around forever, I also got Fc's trying to use it.

I have CM6 RC 2, works fine
just was wondering the setting people with EVO's are changing them to

This is built in Cyanogen Mod too.
Settings/user interface/render effect.
Can also be applied as a widget.
It helps a good bit, if you compare non-calibrated and calibrated, without calibration the colors look too washed out and not as dark and deep.

i want dark and deep, what are the settings to get it like that?

Well, this adjusts RBG but it doesn't adjust contrast for blacker blacks or color saturation. Basically what it will do is make your colors either warmer or cooler. Just play with it till you find one you like. If you want a more 3d effect, choose wallpapers in soft focus (or do it yourself using Photoshop) and icons will appear to "float" above the background.

That **** sure says a lot....
Sorry, I had to. lol. Neat app!

thats pretty cool

I just tried the built in app in CM6.1 and it really gives my EVO a different look. Im using the N1 Low setting.

I find just N1 Calibrated (not cool or red) works best. It really does make a good bit of difference too, try watching a video with it off and it on. The colors feel a bit richer and more natural with the calibration.
I couldn't go back to keeping the default settings anymore

I agree that N1 is best on my EVO. Seems to make the blacks blacker which always makes the screen appear to "pop" more.
However, these are pre-settings. Wit the tweak I mentioned in the OP it is completely customizable. Anyway, whatever works for you.

Posted this in the other thread, but does anyone else get a green hue when scrolling (it's easiest to see in something like the "settings" menu when you scroll).
Any idea if this is correctable?

Did 1.47.651.1 improve color depth?

Before I updated, I remember noticing the background image in the Gallery application always showed distinct color banding (associated with the 16-bit colors, I would assume). I just applied the update and opened the gallery, and the background doesn't exhibit the same color banding now! I'm wondering... did HTC up the color depth to 24-bits?
In looking for a test image, I came across this website:
www . lagom . nl/lcd-test/gradient.php (sorry can't link yet)
If you view it on your Evo, it shows up as a smooth image (similar to what I see on my desktop)! If you drag the page though, it shows color banding...
So my question is: Did this update bring us up to 24-bit color, or is there some sort of dithering being applied to "spoof" the look of a higher color depth?
I heard jboots got nerfed.
The screen does look better, bandung is gone.
seems pretty doubtful although i was shocked to see that the gradients looked better then my laptop, but when you move it around, the gradients show really bad banding, its probably some dithering trick, it does however look very nice

What is jboots
Dotta love them 65k color. HTC really cheaped out in terms of the display.
I haven't updated yet and I know what you're talking about as I've seen the banding before but just launching the gallery right now doesn't exhibit this behavior. I know I've seen it do that before. Anyone know what steps to take exactly so I can confirm the problem exists before I apply the update?

The camera in low light is definately improved. It's faster on focus and a sharper.
The action once the button is pressed to take the picture is much quicker. So it is an improvement.

Check out the "link" in the OP and see what it looks like before you update. Note especially the behavior/look of the gradient image when you drag the page.
Wonder if improved color depth is why they deleted the "Android" wallpapers with this release. Maybe they were 16-bit color depth.

If it weren't for you guys I wouldn't have noticed it so quickly.
The way I can tell something on the display looks better is when you go to the weather widget. The background isn't as spotty where it faded to a light gray/white color from the darker gray around it. It's MUCH SMOOTHER.
In fact, a week or so ago I noticed how ****ty it looked. Wow looks wayyyyy better now.
Man yall are gonna convince me to unroot and update.. I cant though I need my wifi tether.
There's some kind of funny business going on here... If you go into the camera, and then hit the Gallery button from within there, immediately when the Gallery shows up the background looks crappy and banded again, but once the pictures pop up, it's smooth. If you bounce back into the camera for a few seconds, and then back into the Gallery it'll do the same thing again.
Something is wrong with my dithering.
MOAR DOTS!

SGSII vs SGS screen contrast

Have you guys noticed that the overall color & brightness on the SGSII is much "darker" than that of the SGS? I have both devices and side by side, the difference is quite significant. I know the contrast is supposed to be higher on the SGSII, but it almost makes some backgrounds & icons look too dark.
Thanks in advance, and look forward to your feedback.

Can't really tell if it's better or worse, but given I'm coming from S1, it looks a bit dark to me. Maybe just not used to the new screen/contrast...

Thanks, where did you read this? My SGS is running Froyo 2.2.1, so that could be why.
I have with me both phones and I have to say the maximum brightness is about the same for both.
But what is very clear is that the sgs screen looks very blue comparing to sgs II.
Also SGS II's brightness can go down further than SGS which is also good considering battery life.
Probably the color change Google did with 2.3.3
Looks horrid on my nexus s. I used kernel with voodoo to change back the colors
I don't have GS2 yet but I read in this forum that under display setting there is 3color profiles to choose from?

This probably explains it. Flesh tones are darker in the icons and it just looks overly contrasted.
Thanks!
Sounds like that's what it is..I would have though Samsung would have changed them back IMO ruins the overall look of the oled Colors don't pop out at you like they should and whites also...dull look
Wait for kernel with voodoo color you can fix its not permanent.
Did u check in your settings for option to change?

Yeah, tried the background contrast dynamic vs standard vs movie... didn't really do much. Even on full brightness, the colors definitely look over-contrasted on the 9100... especially comparing icons.
I know I'm being picky... but, I still have both phones, and side by side, it's pretty significant.
Coming too from galaxy s and I find the contrast somehow too high..
@cmd512 did u found a solution for this?
To be honest comparing with my old SGS. It looks perfect because next to my S2 it jusy looks b l u e

What about the power saving feature? There is a pretty big difference between max brightness with auto power feature on and off
I never used the captivate at max brightness so the current difference is minimal and my captivate is on a loan for a friend who left his iphone in the cab
much too dark on the dark tones. I'm hoping for a voodoo color to bring back the natural in it . It just sux coming from sgs 1 (with voodoo color also ofc).
Some other things I noticed is that in native gallery an movies app there is an overall sharpness effect. On hd movies it looks ok but on photos it looks really bad.

You can find some measurements I did on the SGSII's display in this thread:
http://forum.xda-developers.com/showthread.php?t=1124669
The issue you are describing is reflected in the high gamma. The high gamma value is even worse with "auto-adjust screen power" option disengaged.
Basically the colors become dark too fast when for values between 30% and 0% of maximum brightness. The result is picture with black crush and loss of shadow details.
I have already alterted supercurio to this issue and Voodoo color should allow me to come up with calibrated values that avoid or at least mitigate this issue.
that would be very cool. indeed I was waiting for a voodoo color (since I don't think we'll see a voodoo sound on this thing). I saw that Cognition rom has a "voodoo color" on the soon list.

(Request) Dimmer screen setting

Now that's I'm rooted and running a custom kernel I am hoping somebody includes a dimmer screen setting, specifically because I still feel the lowest current setting is too bright when reading it night. I know past rooted devices I've owned have had this feature and it worked well. Thanks!
There is an app called Screen Filter which puts an adjustable shade over the screen to reduce brightness. IMO the whites on the samsung are alittle too white for my taste even at the lowest brightness setting. I use Screen Filter every time I read PDFs. You will love it, its free also.

Thanks. Looks like a good app so far. The dev claims that it will affect battery life but I noticed the soft keys stay the sam brightness which tells me the screen brightness isn't actually being changed. Hopefully something will be baked in to a future ROM.

It will only increase battery life for tablets and phones with AMOLED screens. The tab 10 has an LCD screen so battery life will remain the same.
I second that Screen Filter app. I use it on my DroidX and now the GT10.1. The fact that you can setup a widget for a specific brightness then tab the widget again to go back to the prior setting.
Bump. Any devs working on this for a rom feature?

Want accurate colors, but cool whites like LCDs? UPDATE: No longer works in 5.1.1

HDxDaniel discovered this trick on the Note 4, but it works great on the S6 as well. This hidden screen mode gives you accurate colors like basic mode, but cool whites like adaptive mode. It's great for those of us who don't want super saturated colors, but also don't want super warm whites. This screen mode basically makes the S6 screen look like an iPhone or Nexus 5 screen, so if you came from either of those phones, you'll probably like it.
Here's the thread detailing how to set it:

Good find, Thanks for sharing
Looks like it needs to be set again each time you reboot. A little annoying, but not a huge deal.
Interesting!
Works great. Don't understand why this is hidden. I love basic mode but those whites have really bothered me. This new mode seems a bit too bright but I suppose I just need to get use to it.
The white do look better, but I think it makes the colours look washed out.
Nice find. Looks pretty decent.
So it's clear to me after some testing that the colors aren't quite as accurate in this mode as basic mode (reds in particular), but they're much closer to accurate than any other mode apart from basic. I suspect this is because this color profile was designed for a Galaxy Tab AMOLED screen with slightly different characteristics.
I wish we could create our own color profiles. Any devs tried finding the included ones in system or in the kernel code?

But they already gave you a choice right now, adaptive/cinema/photo/basic.
They could easily add another one.

Google or srgb?

Hey People, i was wondering what all of us are using as screen settings and why.
For me srgb looks certainly more accurate but White are yelloish, they look better on Google's calibration settings but then colors are too saturated... So for now i still haven't made my choice. How about you? What do you use?
Well I'm running DU ROM which comes with a custom kernel. To me, stock colors don't pop enough. I left the RGB values alone and simply bumped my saturation to 35. Display looks great at this setting for me. I've tried a hundred different display settings and for me this one looks the best. I use kernel adiutor to adjust my display settings
Thanks mate, still haven't made up my mind as to routine n6p should i need assistance for it.... Take YouTube screens for instance, that red punches Soo much to me
Running custom kernel and I use the same profiles that I used on my N6 to get 6500k.
I'm using screen adjuster +8 on blue
Gives better whites... Anyone tried color screen filter from play store? Might give some more options I think
I use 100% stock screen settings. I like the way Amoled looks. SRGB looks washed out and boring, even if I compare it with my Nexus 5 (2013) screen.
