That sounds nice, now I just hope it 's not an empty promise that this doesn't use an filter-overlay.
Did you try the manual calibration (Custom-Settings)?
A before (=disabled) and after (=enabled e.g. with RGB set to 100 200 255) screenshot of a 100% white or white to black gradient would be really nice!
Anyway - thanks for confirming!

Hey, thank you for the discovery.
I can confirm you that is not an overlay. The screenshots made with the filter applied remain the same than when the filter is disabled.
I was using CF.lumen with its driver to use custom RGB values. The same happens with it, the screens are the same with filter and no filter, so neither of the two use overlays.

... seems to be not as easy as with Qualcomm due to the lack of KCAL support. There also seem to be no Kernels around for Exynos variants where anyone has ever managed to do this (as far as I found out, correct me if I'm wrong)
So far I only found one clue that is not using the usual Color Filters but seems to be changing the RGB values directly ...
In an older review someone reported that this app was working with older Exynos SoCs for them:
https://play.google.com/store/apps/details?id=mobi.omegacentauri.red_pro
Apparently it should also work for Android 6 - as I do not have root yet can someone test if it does work with the S7/S7 Edge Exynos variants?
Otherwise we can only hope for Samsung to include Color Calibration from Android N in their official release (if they aren't to lazy and simply remove that feature)

The Pro Version [v1.11] worked perfectly on my Exynos S7 Edge. {requires root}
Thank you for this! :highfive:

Color Calibration ( Blue tint fix :) ) - Needs some work though

http://forum.xda-developers.com/showthread.php?t=745248
Have a look (not my work, just wanted to share)
This little fix lets you adjust the colors, so I thought you would be interested.
It does seem to screw up the camera (only white preview) , but other than that it works great
howto: flash the zip in CWM and then install the apk...
so when the camera bug gets sorted it would be awesome

isn't that what Supercurio's Voodoo Color does ?
where can I acces the voodoo color settings?
I use darkys rom (9.3) and voodoo should be included but I only find an Voodoo control app which adjusts the sound but not the color.
In CWM I can only adjust lagfix settings?
You can use Galaxy Tuner for that.

the Voodoo Control App includes the settings
you only need to switch to a kernel which includes newest Voodoo Color changes
(dunno if it exists for 2.2* kernels though)
Well I just installed the latest Voodoo kernel (5.4.1) but no changes
If I'm not wrong that voodoo colour app only apply to nexus s.. Not available for 2.2..

from what I can gauge from all this, is that certain parts (screens) used by Samsung were not capable of screen variations in/for later builds as such they totally declined further upgrades for all. This would be common in manufacturing the initial device (galaxy S) as trial and error would play a part in releasing the most cost effective product and the part used coming from different sources. The Galaxy S had 20 versions, meant for different locations and pricing, so the componaents would be from from various sources, some of top quality and others of lower grade going to lower priced models meant for third world locations.
so it may be wise to see when and where this models having blue screen problems are cropping up most.

That's a very interesting thinking.
I just found out that this problem appears to be a known issue which is caused from incorrect calibration data which exists in some devices and affected by cyanogenmod 9+ (the later 9 ROMs, some of the older don't have this issue)
I think I'll post a new thread to help people understand this problem and its origin, and in the same time I might ask them their model and location, according to your great suggestion.
Thanks again!

bluish screen - dark blue tint / hue after flashing AOSP ICS and above on GT-I9000

There's a known problem for a little amount of Samsung Galaxy S GT-I9000 devices that are getting bluish screen after flashing AOSP Ice Cream Sandwich (4.0.x) and above.
By bluish screen I mean that there's a dark blue color, a blue tint / hue all over the screen.
This bluish screen appears everywhere in the ROM, in the recovery, and even when charging the phone while it's off.
According to DerTeufel1980 and pawitp, this issue is caused by the updated framebuffer driver of the Nexus S in the CyanogenMod 9 kernels, and the actual problem is that some devices contain incorrect calibration data.
I posted a thread in which I summarize all I know about this issue.
This issue is fixed thanks to pawitp.
We can flash this fixed CyanogenMod 11 nightly.
Any release from now on will be updated with this fix.
There are detailed instructions in pawitp's thread - [NIGHTLY][ROM][4.4] CyanogenMod 11 for Samsung Galaxy S
This is the official thread of CyanogenMod 11 in this forum.
Please note that in CyanogenMod's download site we should flash any version that is newer than cm-11-20140211-NIGHTLY-galaxysmtd.zip which was posted today, the 11.02.2014, at 04:51:57 (according to the "Date Added" column in the download site)
I'd like to appreciate pawitp for his willing to help and for his truly tremendous effort to the community.
Thanks a lot!

HTC One (M9) Colour Control Screen Settings

Hello!
My first thread on XDA Developers.
I've been a lurker on these forums for some time having used various custom ROMs and kernels for Windows Mobile, Windows Phone 7 and now Android. I've mostly been a big advocate of Samsung gear until they decided to release the S6 with no storage expansion as this is what I looked for in any phone I upgraded to. This led me to buy the HTC One M9. The community so far has been great with custom ROMS and Kernels with the limited sources provided by HTC so I figured I would give something back to the HTC One M9 community.
Now it has been said that the HTC One M9 screen is not as great as it could be and is in fact a downgrade compared to the M7 and M8. This is mostly due to the fact the screen is calibrated very "cool" (8500k) temperature. With that in mind I just used my X-Rite i1Display Pro to get the white point to D65 (aka 6500k) and succeeded within a few minutes.
The settings I have are for the HTC One M9 UK EE gold/gold edition but I'm sure the settings can be used on other variants from other network providers in other countries too as it will at least get you close to D65 for more accurate colour reproduction on the screen.
I guess I've said a lot so I'll shut up and share the settings with you - please note I've used the colour control aspect of the custom kernels available to make the changes.
Ew that's crazy yellow lol. Try mine
I forgot to mention the rest of the saturation, value, contrast, hue need to be set to their default.
Considering my settings are not working on yours Reubenskelly1992 and yours are VERY blue, even more so than what I had out of the box on my M9, could it be there's a much bigger variation in screen quality?

My blue setting has to be at 230 or it's way too blue

Mine is LCD: TDI_RES_69338
I have tried many different settings taken from the forum. But I think the most similar to the setting of M8 (maybe not the preferred for many) is mine, for now. Try it, tell me what you think.
At what brightness do you calibrate the colors at? Does it matter?

On general these should work and it's a guideline so every device may be slightly different but probably just a little bit of tweaking

Axon 7 Screen Color Oversaturated

Folks,
Anyone facing issues screen color over saturated with stock rom? Any one had any tools or apps which can re-calibrate or fix it?
If you have rooted your Axon 7, then you can install the Color Control app. This app will allow you to calibrate the screen color. Should this app doesn't work, flash the KCAL kernel patch for adding this feature to the stock kernel.
Enjoy!

No, the kernel doesn't support this hardware feature and the app requires root access to modify the settings. So the only way is unlocking the bootloader and rooting the device.

Isn't changing the default setting to "natural" enough though? I find the color quite washed out with that mode. TBH the main problem for me isn't saturation but rather contrast: colors seem to "melt" with one another, particularly on 3D games

I keep mine on gorgeous and normal and it looks great. I like punchy colors. Shows off this great AMOLED screen.

i'm doing the opposite, lol, i'm experimenting alot with some of the S8+ themes (dark notifications, etc) and Substratum themes to make my FE to my liking. Installed the System Tuner App (from the Playstore) to better control notifications, apply 25% animation speed and remove the battery icon. i had one incident where a Substratum theme caused the screen to go blank, but used ADB to uninstall the offending apk and was back in business. right now i've tried to ASOP-isize my phone with SwiftDark AOSP Status Bar Icons, Google Dialer and a kanged version of BlackNotificationsOnly where i'm using a light gray background vs.100% black. Using Adhell to block adds and for the most part it's working well. I flashed the S version ROM to my device to see what, if any differences exists and then flashed back to the original K version. so far, no major issues.

[REQUEST] Add KCAL support to stock kernel, it is possible?

Hi, since our Mi A1 display is quite pale (and color calibration is inaccurate), it would be fantastic to have KCAL support in order to use for example Kernel Adiutor to calibrate the screen (as we can do with Redmi Note 4 global on Lineage OS rom with patched kernel). I have tried with Color Changer Pro but it's pretty limited (saturation change give poor results).
Now that the sources are released (even if nougat-based) , it will be easy to apply using the guidelines in this post https://forum.xda-developers.com/android/software-hacking/dev-kcal-advanced-color-control-t3032080 ?
Thanks in advance
PS: sorry if it's quite similar to a mine old post, but I have posted it in the wrong section last time, so I please mods to cancel the incorrect post.

well it's too early to demand anything in kernel as far as i saw devs here all are in try to make custom roms well I don't think it is much necessary (we are on stock already) we need custom kernels first so if a one developer should work only to make kernel source stable it would be great and yes this features would be implemented but we have to wait
in a month we can get android 8.0 stable kernel and OS i think

I have seen hundreds of mi a1, screen is far form perfection, colors are under saturated and contrasts are poor. G3 had poor colors too. Redmi Note 4 has the same problem (and a quite similar panel), but with kcal I was able to do big improvements to the screen. I attach an example.
LEFT -> Redmi note 4 calibrated RIGHT -> Mi a1 hope you can appreciate the difference, it's not easy to show it in camera

I have seen hundreds of mi a1, screen is far form perfection, colors are under saturated and contrasts are poor. G3 had poor colors too. Redmi Note 4 has the same problem (and a quite similar panel), but with kcal I was able to do big improvements to the screen. I attach an example.
LEFT -> Redmi note 4 calibrated RIGHT -> Mi a1 hope you can appreciate the difference, it's not easy to show it in camera

Just read my post again.

I see what you mean... still i don't think there is much of difference for an ordinary usage.. for such low level device I don't think we (I) should have expect anything different and in the end ... it is still an old IPS technology so for really sharp and accurate colors - AMOLED. In the end it is a matter of taste and as this device is yours you should be able to modify it up to your taste.
I find colors of mine very close to what Nexus 5x delivered, which was supposed to be very accurate. AMOLED is usually anything but calibrated, punchy & nice, but not accurate. But there seems to be a great variation of different LCD panels in Mi A1, so I was probably the lucky one..
