How to remove oversaturation and incorrect gamma? - LeEco Le Max 2 Questions & Answers

Is there any way to remove the horrible post processing for the screen that makes everything so oversaturated and crushes the colours, shadows and shading?
I have changed the colour mode to "natural" from the "le eco" default but it is still way over saturated and not at all correct. Reds in particular are very oversaturated, although it seems to happen with all colours to a degree. The other colour modes are even worse.
Is there seriously no way to remove this? Or is it part of the firmware for the screen rather than part of the phone software itself?
It's an extremely stupid decision to post process and alter colours and have no way of turning it off.
I am on the default x829 fw: 5.8.016S if that makes any difference.

Also have the same issue.
I also have this over saturation issue on my x829 running stock 16s software. I cannot find a way of solving it as you seem to be the only other person I've found suffering from this issue.

I think it's just the kind of issue that most people don't notice (or worse, think it looks "better"). Certain content makes it really obvious and it loses a lot of detail.
Seems like a conscious choice so I doubt it's something that will be different in the other roms but as I haven't tried any other roms i don't know.
I hope it's done in software rather than the screen firmware, so that it can possibly be more easily disabled (corrected) in cfw.

Mine looked oversaturated with the reds too.
Your cases may be more complicated but mine turned out to be an oversight on my part of not clicking OK (at the top right of the screen) after selecting the desired color mode. Changes would't stick without clicking OK.
System: Indian 19s.

Thanks for trying to help!
Unfortunately I already did that and am already correctly in the "natural" mode - it certainly helps a bit compared to the Le Eco mode but is still too saturated and the gamma is too high. All the contrast is way overblown which ruins subtlety in shading.

I am getting loads of black crush which is the most irritating part.
Can people test here:
http://www.lagom.nl/lcd-test/black.php
I can only see down to 20 on normal brightness settings.
If i turn the brightness all the way up (with adaptive brightness off) then the screen is utterly blinding and i can still only see down to about 9 or 8.
http://www.lagom.nl/lcd-test/gamma_calibration.php
The gamma is messed up too, i'm getting about 1.3 / 1.4 at 48%, 1.6 at 25% and 1.8 / 1.9 at 10%
As you can imagine it really is spoiling the phone.

nougat ROMs have KCAL app support, atleast Omni does... have you tried it?

I thought KCAL didn't support the snapdragon 820? At least it doesn't list MSM 8996 support??
https://forum.xda-developers.com/android/software-hacking/dev-kcal-advanced-color-control-t3032080
That would be great if I could use KCAL. However I am nervous of using Nougat roms as I heard that they break the camera and other features on the phone?
In fact I have not changed from stock firmware as I have been unsure what is the most compatible thing to change to.
I don't care about breaking the fingerprint sensor though, as I never want to use that.

Hello did u solve ur problem.. Im facing the same

No, i didn't yet, sorry.
I posted about it in the small eui thread but no one seemed to pay attention. I will probably make a thread about it to bring it to people's attention as i am guessing it affects everyone's phones.

Just install kernel auditor on Omni or any rom that supports kcal. I reduced saturation to 20 and looks much better.

What is kernel auditor for if omnirom has kcal already? :S
The thing is i would prefer to keep on an eui based rom, like small eui or cuoco92 so that i don't break anything on my phone.
But if it is really not possible to fix with those then I will move to something like omni-rom. I just don't want to break phone functionality.
Also, the biggest problem is the black crush rather than the gamma - check the link i posted and see which squares you can see down to - it's really bad! Hopefully this can be fixed with kcal too...

[REQUEST] Modding the LightSensor

Do you like the light Sensor on Nexus?
I didn't like it.
It's a very good feature, but it works strange.
It is slow in dimming and took already not enough light to the display.
Nexusdisplay is dark dark dark...
Does anybody know, how to tweak this sensor?
Or am I the only one who dislike it very much?
I just set my brightness manually. Done deal.
Perfect.
In the Night I'll put my sunglasses on or at a sunny day I take my nexus blind...
Wherefor is the sensor if it don't work proper?
There must be some settings for...
I think the light sensor works great but it would be even better if we can customize it a little bit. Something like scale up the screen brightness for each level of external light.
Or something like auto lock when it is totally dark (you put it into your pocket?).....but that would cause trouble if you want to use your phone in the theater
I think the light sensor is terrible. I have tried everything but it still seems very finicky on when it will work properly. I regularly go from low light to sunny outdoors and having the feature would properly would be awesome, especially since it worked fine on my last 2 phones and they arent even close to being a superphone.
Trying to make it transition smoother is something I've been meaning to try. The settings for this are in the source tree at frameworks/base/core/res/res/values/config.xml (I override this in my passion vendor overlay). You can tweak the values and rebuild framework-res to try it out.
oh cyanogen, You Are GOD!
Where we can find it?
I've searched the whole framework.
ha he meant the source tree for framework provided by google. not in the framework-res inside of the zip of the rom you are using.
two things I noticed about it:
1 It dims and brightens too quick, it should take an average light level over a longer time period
2 Our fluorescent lights in the office at work seem to confuse it, so that could mean that the lens is too focussed and if you hit one of the lights it goes too bright, miss and it goes too dim as you move around and/or the wavelength of the lights confuse it - though this problem may be more bearable if #1 above is fixed.
I gave up using the sensor. I use the power strip. the 3 settings work great for me.

Yes, these words are soooo true! They're absolut true.
And: It's not HTCs first device with such a sensor. It's not the first android Handset with such an sensor.
I can't understand, why they did such a thing!
@spyz88: I'll pray your words every time if i see this dumb dimming and flickering.
I too have noticed this problem, and have such, turned it off. Disappointing, yeah.
I hope someone can come up with some good idea/settings, to fix this like google should be doing already :/....
Thanks people

You can pay £30,000 for a car and things still don't work properly.
Nature of the beast I'm afraid.
OK, we can put our heads down in the sand or we can try to make us happier with it.
Does anybody tells google/htc that this is crap?
Probably we can make it on our own.
yeah it doesn't work very well. Maybe sensitivity needs to be lowered somehow
I hate to say this because I always talk crap about the iphone, but the iphone does have a better way to auto dim the screen with the sensor.
I thought I had a problem because from the get go I installed a screen protector that lays over the sensor, but now I see that other people have the same issue.
It is funny because I can have the phone in one place, but if I change the angle the screen will dim or brighten.
the worst thing is , it comes in the way of reading constantly on your phone , and after two to three cycles of dim/bright , you would eventually give up and disable it. disappointing .
but i think the problem is it samples ambient light with long interval , and then average it in a way that is always behind what it should be
This has bothered me as well and I've been looking for an easy way to fix it.
It seems that the light sensor (or its driver?) is to sensitive or inaccurate. The reported LUX value can fluctuate a lot in constant surrounding light. There is also the possibility that one waves a hand in front of the sensor which can produce undesired brightness changes etc.
My idea:
PowerManagerService.java (frameworks/base/services/java/com/android/server) listens for light sensor changes with a SensorEventListener. Either directly or after (config_lightSensorWarmupTime) a method called lightSensorChangedLocked is called with the sensor value as parameter. This method sets the brightness.
Here we can add some low pass filtering to the sensor value before calling lightSensorChangedLocked. Maybe a simple average of the last 5 values or so will suffice? Maybe take time into consideration as well. Say average 5 or all values received in the last 20 seconds or so. There sure are room for improvements of my suggestions.
My message is that the issue is perfectly fixable and PowerManagerService.java is the file to fix it in.

[Q] Screen Color Temperature

While using my Tablet throughout the last month, one thing has really been bugging me. The screen seems to be very yellow. Rather than showing white screens as white, they're off-white, greys look a bit darker and greener than they should. The color temperature of the screen is very warm, and it bugs me. Anyone else experience this? Or do I just have a bad screen?
Better question, does anyone know of a fix for this? I'm hoping it's not a hardware problem, but a software one.
Try taking a screenshot ("n" + volume down) of this and let us look at it. I'm guessing if its yellow to us as well, its s software issue. If not, its likely a hardware issue.
Judging by your screen temp, early guess its a hardware problem, but lets see what the screencap shows.
Sent from my Nook Tablet using (((sonicboom)))
There is app called Screen Adjuster that you can grab from the market. It will allow you to change the color of the screen. I use it for night reading tobreduce the blue.
Just remember to disable it when installing apps. Otherwise the install button will be disabled.
Alright, so I grabbed a screenshot and sent it to my Droid X, which has a totally neutral color warmth, and the shot looked perfect. That's a little depressing, but still, something tells me that it has to do with the stock B&N, cause I know Google did something like this with the Nexus S for "enhanced contrast" or something like that.
I know this is probably wishful thinking, but I'd still like to believe there's a way to fix this.
Also, I tried Screen Adjuster, but it doesn't seem to fix the problem. It seems to just put a filter over the screen.
There was a thread about the color temprature early on in the life of this forum. The OP is a professional photographer and was bothered by the color balance of the NT: http://forum.xda-developers.com/showthread.php?t=1354639&highlight=warm .

Touche. I did try the fix listed in there, but it didn't work (for a number of reasons). The problem has essentially been ignored since then, so I'm assuming either it doesn't bother that many people, or I have a defective unit. That's why I'm asking if anyone else notices it.
Though now this thread does seem redundant..
Seems the NT is a bit more yellow than standard.
http://www.displaymate.com/IPS_Tablet_ShootOut_1.htm
The Nook Tablet also has a very good factory display calibration. Its gray-scale is actually more accurate than most living room HDTVs. The White Point at 6,016K degrees is somewhat more yellowish than the 6,500K standard – that was most likely done in order to increase the screen’s maximum brightness, power efficiency, and battery run-time.

Questions: Speakerphone and Screen Saturation

I just got a Galaxy Note and have some questions and concerns:
1. The speaker seems very tinny and distorted anywhere close to maximum volume – almost like a blown speaker rattles. It sounds like I am talking to someone via two tuna cans and string. Can you crank your speaker phone volume all the way up without any distortion?
2. Screen color saturation: The colors are way too over saturated. I’ve made the cursory adjustments to brightness and found one interesting app called “Screen Adjuster” and while it allows for general color balance and contrast changes, it won’t let me do much anything with saturation. Anyone know of any apps specifically designed to do this or how to adjust color saturation on this gadget?
3. Screen in general: I had to turn off Automatic Brightness as it seems the screen was dimming/lighting every few seconds. Has anyone else had this issue with their Note and perhaps might have a fix?
4. I’m assuming the only way to get the “Yellow Pages” (YP Mobile) app off and out of my contact list would be via root and a custom ROM, eh?
Any help appreciated.
Thanks.

Having the same thoughts here. Have learned to deal with it, but would rather "fix" it.

Regarding screen saturation, I've read on some other threads that there may be an option in the ICS international version for this setting but I haven't found any definitive screen caps to confirm this. If anyone running ICS can, that would be spectacular.
I've scoured the app market to no avail. I humbly asked the very swell fellow who wrote "Screen Adjuster" to see if he might write a fix but I'm not sure how difficult this might be.
The bottom line is what many people perceive as "color pop" to me isn't at all. It's a simple over saturated display problem. I'm a photographer and one of the reasons I got this device was to be able to lose my Asus Transformer and use this as an on the go gallery display device, but I'd never show anyone my work on this gadget - it's simply so far off of what real colors look like.
I may have to send it back at the end of my 30 days. Damn shame as I am really coming to like some of the other pluses.
If I figure anything out, I'll post back as from reading other threads there are more than a few people who aren't thrilled with this.

Thank for the reply.
I'm on GB right now, and won't be switching to ICS for a while.
Hopefully something pops up.

Question Finally got my phone. Dull colors? (edit it's fixed)

I bought my phone in USA and had it shipped overseas. I finally got it and, compared to my OnePlus 7 Pro, the screen colors seem very dull. Is this normal? If I put "cinema" option it is even worse (very yellow). Is the screen supposed to be "natural colors" like the photos it takes? I do want photos natural colors, but would like the screen to be vivid.
Also, is there a way to uninstall the 4 GB of games it comes preinstalled with? What a terrible decision if you can't remove it (without root).
Edit. I am not 100% sure on this, but using the phone a few days seem to have made the screen colors way better. Nos the colors do look vivid in the standard mode.
EDIT 2 I pulled out the OnePlus 7 pro that initially had better more vivid colors to me, and now the Sony is way eat better. I don't know if it was the updates the phone had, or if j was comparing Sony cinema vs OnePlus vivid before. Loving the phone screen now.
You are right bro screen colors really really bad Sony must give a update about...
Colours look fantastic and accurate to me, most phones have quite an unrealistic vibrance to the screens. Not sure on how you'd go about increasing it without root.
You can change the white balance under display settings, that would fix the yellow tinge.
I also think the colour of the screen is fine. I'm using Creator Mode. Most OLEDs are too saturated for my liking.
At first I felt it lacked the vibrant pop that I was used to from other manufacturers.
But I set it to creator mode and started to get used to the accurate colours and really appreciate it now. Just stick with it, you will soon get used to it.
Also I got no idea how to get rid of the games. I just disabled them.
In past xperia devices also had "vivid mode" in screen settings.
But since sony is obsessed with feature and function removal they decided to remove this as well :/
Software wise xperias are complete misunderstanding.
I bet there is someone sitting, going through the code and wondering what else he can remove / cut off...
I think Sony must give "Vivid Mode" also...

You can uninstall all the games using ADB. If you don't know how to use it then you can read up on it over at XDA. But even when you do "uninstall" them they are NOT really uninstalled. They are only uninstalled for you, the primary user identified in ADB as user 0 (zero) and if you were to do a factory reset they would just show up again. The only way to truly uninstall them requires root. They do not take up any storage of consequence and disabling them accomplishes basically the same thing as ADB does.

Yeah, I found the adb shell commands to free up that space.
Also, the colors of the screen seem to have gotten way better after a few days. Does screen "warming" exist or might it be my eyes got used to non ultra vivid colors I had on my OnePlus?
Get a Color chart to check throughput from cam to display. Ambient shooting light color temp will effect results to some degree. Compare display image of chart photograph to the chart in the same light as it was shot. Both the image and the display image colors should look identical if the display is dialed in correctly.
Most displays are oversaturated as previously stated. Reds tend to blowout first. This looks vibrant and very unnatural... I hate it. Look at face flesh tones to help gauge color accuracy.
If face colors look natural on the browser, in photos, the setup is likely close to optimum.
Tattoos may photograph erratically due UV reactive pigments especially in sunlight... this is normal.
Still they should bring back vivid mode.
It is better to have the option rather than not having it. If someone likes washed out cinema colors = fine, but if someone prefers more vivid colors should also have such possibility to select it.

Question Do you have this display issue/defect?

Hi all!
Shown is an unfortunate issue I've had with the displays of two 1 IV's (US/512Gb models):
(just uploaded this as of posting so the higher res may still be encoding)
I use my phone frequently at night and the display is noticeably off/blown out/seemingly defective at lower brightnesses, especially in the evening. I've already been through the exchange process once for this problem and it took weeks, luckily I caught it in the return window. Now I'm deciding whether to try yet another exchange or just return the new one, because sadly this issue is a deal breaker for me.
Please let me know if you're experiencing the same issue so I can determine whether or not I want to gamble my time with another one of these, as I strongly suspect/fear this could be a widespread hardware defect that has gone relatively unnoticed. Either that, or I got two phones from a clearly bad batch.
Link to image shown in video if you'd like to see if yours has the issue.
You can see the problem best in scenes with very dark color gradients, mostly in the very black range. Most of the time it's not exactly easy to notice especially if you're not looking for it. The display looks flawless and brilliant at 90% and above, although interestingly "creative mode" also seems to degrade color quality. I had an Xperia 1 II before this and creative mode didn't have that perceived negative effect at all. In fact I had exactly 0 of these issues on my mark II.
60/120fps, HDR, etc all don't seem to change the issue, nor did a factory reset or the Xperia Companion app as suggested by Sony. I'm going to escalate me case with them tomorrow to see if I can get any more info. Found another thread about the issue/similar issues.
Sorry about the novel. I'm kinda sad about this whole thing because I otherwise absolutely love the phone.
Yup everybody has this issue. I'm convinced people who say they don't have it are just too blind to notice. I've not seen any video of a 1IV that shows a screen that doesn't have the issue. I always just keep my screen at 90% brightness and just the "Extra dim" quick toggle to make it less bright. If I'm in bed on my phone I use OLED Saver to make it even darker.
Well, I can't see that on mine.
Maybe not the best example, but this is a picture I took this summer, one is at max brightness and the other one is at some 60%. Tried with some other darker photos I have and no traces of that green tint.
Also, my phone switches to dark theme at night and with automatic brightness it certainly goes way below 90% and still everything looks black. Or at least not that obviously green.
...You realise that's not how a screenshot works, right?
Yeah, was just an example photo. But cannot reproduce that. Found topic on reddit, gonna try some HDR stuff but have to say that if that's what triggers it than will certainly never have the problem with it.
Just borrow a mate's phone and film your screen while you adjust the brightness above and below 90%. The difference is very obvious.
Then it should be obvious to my eyes also, like in his video. And that does not happening on the above photo. Anyway, gong back home tomorrow so will play with it a bit more.
No issues on my rooted device.
