Improve black on white text - Epic 4G General

Black on white text on epic sucks. You can see jagged edges and color artifacts. I understand that this is AMOLED, but one of the roms did improve that! I don't remember, which rom it was, it is no longer available and syndicate rom font rendering is the same as stock.
There was part of that old rom I used supposed to improve font rendering, I don't remember its name either.
Or am I the only one unhappy with book reading/browsing on this otherwise great device?

I can't much tell a difference, but I think that it was a voodoo color enhancement that you might be talking about.

Yes, voodoo color, thanks! It adjust default sharpening strength. Is there a way to add voodoo to a non-voodoo rom, on epic 4g? I can't find the way...

Just an FYI, i do agree with what you are saying, the Kindle for Android has three dif color options for reading, if you are inclined to read your books through there.

Yes, just use a kernel with voodoo. You can keep the same rom.

Awesome Color Calibrator from the Nexus Forum!

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.

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?

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.
Better or worse? Than s1

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...
Isn't gingerbread supposed to be a bit darker than froyo?

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.

Voodoo Colour vs stock

Title is self-explanatory really. What are the visual differences between Voodoo colour and stock? Screenshots will be nice.
screenshots would be uselles as voodoo color affects the screen driver and its effect is only visible on a physical device itself...
about colors in a nutshell:
stock is just stock - ****ed up gamma, no control over temperature whatsoever, also oversharpened. some screens have massive blue or yellow tint.
voodoo color gives you ability to control each RGB channel and gamma individualy which is the only cure for that tint, also better gamma table... but some say it doesn't look good on some devices, even the creator supercurio doesn't encourage devs to implement vc. Personally I use only kernels with vc because my screen has massive blue tint.
There is also color improvement done by hardcore which is implemented in few kernels arround, again, it provides great results for some users, but mostly for devices with neutral color temperature.
so if you have neutral stock colors, go for speedmod color fix, if you have some color tint which you want to get rid of, go for voodoo color
i just can get voodooo to work on the ics with glados v2.3 kernel...
---------- Post added at 08:37 PM ---------- Previous post was at 08:37 PM ----------
i mean i CANT...
Ideally, we need an app to change colour on stock kernels. Like this on i9100 http://forum.xda-developers.com/showthread.php?t=1366280.
Unfortunately it doesn't work on i9000.
Interestingly, this "mdnie switcher" does work on our device (at least on galaxian kernel that I have tested) to let you change modes is "warm" "cold" etc that you find in the video app plus more http://forum.cyanogenmod.com/topic/35944-samsung-galaxys2-mdnie-switcher-for-color-profiles/
Not as useful as an app that lets you modify the color with sliders :S
I believe this app must be possible. After all, galaxy tuner did it on froyo (doesn't work on gingerbread though).
You can adjust RGB levels with slider in chainfire3D Nightmode function.
Supercurio is also planing to make an app like that (here in its current state) and to disable voodoo colour as it is right now (he considers it deprecated).

Thanks, I hadn't heard that before. Good to know he is working on it, hope he releases something functional soon!

Lack of voodoo color support?

I don't know if its just me but almost every kernel that I've used that supports voodoo color I can't adjust the gamma values. Is this an ICS thing? Sorry if this is a stupid question

You probably have i9023 variant of Nexus S, which has SLCD not Samoled. Voodoo color only works on Samoled display.

Nah, I have the T-Mobile variant, the i9020t. Voodoo Color was working fine I think back on air kernel 3.5 I would just have the green screen bug cause of my gamma values but now my gamma values don't do anything only if i raise them, which makes my colors appear darker? By default my screen looks a little washed out color wise.

That's not a voodoo color problem. I remember that r_data did that on purpose to eliminate green screen thing. If you don't like it, you can always use a different kernel.

Thats the thing I've tried different kernels with voodoo color support and its all the same thing. :/ I'd love to use Air's kernel if my colors didn't look so washed out to begin with

Can I flash a kernel on stock ROM?

If so, would you mind telling me which ones have color calibration? Can't stand these washed out colors.

The colors are not washed out, they're actually more accurate than all the amoled displays out there. The Xperia's have washed out displays, trust me. Also, pretty sure you can't. You have to root, switch kernels and then fix the colors through various apps.

Try out Franco kernel, you'll benefit from it, in every way.

Flash faux kernel or Franco and use trickster mod or faux app to control colors and gamma. Faux display app has some awesome presets for colors that really make the colors pop and get rid of the gamma wash out. I cant stand the stock gamma either, too washed out.
