the truth about gamma - G Pad 8.3 General

well gamma is a big problem for our gpad, anyone know.
resuming...
4.2.2 v50010a gamma 1.6 - 1.8
4.2.2 v50010b gamma 2.0 - 2.1
4.4.2 v50018a gamma 2.2 - 2.4
4.4.2 v50020a gamma 2.0 - 2.1 AGAIN!
apparently v50018a is the best but checking with display tester not only the gamma but also the black and white saturation test... surprise!
the level of black and withe is the same!
i also compared gpad with my other tablet: asus memo pad hd 7 that have a much clear display and a gamma 2.2 - 2.4.
comparison side by side with display tester and a brightness comparable with 100% for gpad and 85% for asus:
asus go deep in black and white saturation test with more "seeable" blocks.
gpad: black 7 - white 250
asus: black 2 - white 254
only solution is the app "screen adjuster", with a contrast of -30 for gpad i have same results of asus in black and white saturation test.

How do other roms fare?
Also, there is a version 4.4.2 v50020b now

I am just sticking with 18a as in my sig. Aside from the lack of QVoice, everything works and is fine.

At 100% brightness the g pad does great. It's less than 50% is where It fails. Custom kernels for 4.2.2 fixes that problem (video watching). When we get the source from LG for 4.4.2 it will be fixed by the community again.

Honestly id be happy with any gamma if i could see 0-255. I swear its set for video levels and you can only see 10-245 ish before its all washed out.
Still ive seen alot worse. At least pictures dont look washed out and blacks dont look grey.

Colors on Android 2.3.4

After updating to 2.3.4, I notice that (to my eyes anyway) the colors seem to have been adjusted again. As we all know, Google messed with the color temperature in 2.3.3 to the chagrin of many. Complaints of yellow screens abounded. Mine had a slightly yellow tint to it as well, however it seems gone with 2.3.4.
I have always felt the best, most accurate colors available on the Nexus S were achieved with Voodoo. It appears that 2.3.4 matches it.
Are my eyes deceiving me, or are the colors really better? Anyone agree?
removed i was wrong
Something definitely seems different. Maybe a little brighter.
removed i was wrong
i couldn't tell any difference from 2.3.3. they look more natural, perhaps with a very (and i do mean very) slight blue tint. the whites are in-your-face as before, but i found it really difficult to read the browser before, now, it's not so bad.
The colours have changed, are better and look more vibrant. I'm happy again.
I have 2.3.4 and my yellowish tint is still here. Not a major concern to me but just figured I would share.
Yellow tint is still there. No difference in colour temperature.

Colors did not change.
However, I think the colors on 2.3.3 were fantastic, so.... you might not value my opinion much anyway
Sent from my Nexus S using XDA App
Display issues still not solved
I wonder when they will fix this issue.
I want the yellow tint to be removed. From what I read voodoo kernel fixes the issue. So I have 3 questions. Can somebody answer them?
1. Is it possible to root without wiping data?
2. Can I flash voodoo kernel on 2.3.4?
3. To test voodoo kernel do I need to root the phone?

I agree with this too. They're more natural this way. Yea, even though they've lost their saturation, but that's the whole point.
Until someone shows me a side by side comparison I am standing by my statement "the screen colour definitely changed" other than that, I don't know because I cannot really tell that well, I cannot say for the better or for the worst, please does anyone have two Nexus S devices to compare?

It's not true. You do not need to compare devices side by side. You only need to look at the source code which DID change between 2.3.2 and 2.3.3 but DID NOT CHANGE between 2.3.3 and 2.3.4.

Yeah its a good start, they are similar to what I ended up with after an hour of messing around with the phone. The thing that sticks out to me is the screen clarity definitely suffered. If you get a picture that has tiny details like a black leather wallpaper that shows grain, there is a noticeable difference from stock to the above posted settings in shadow detail and image clarity. I'll keep messing around with it more and post later on.

Nope. This setting will be safe.
Also,
And just as an update, glitch's new kernel fixes this issue (beta tested atm); so you will be able to use any setting you want without the screen freaking out once he releases it.
Anyone have any better settings for our device? The nexus s ones look pretty good. Anyone do a pro calibration yet for the fascinate?

I'll post my setup just in case anyone else finds it useful. I found that some of the settings posted were somewhat red/green when the screen was really dim (my dim setting is at 10), so I blued it up a bit. Things may not be all that different from stock, I haven't really compared.

Well, tried all the other listed here...liking yours the best so far..wish the app allowed you to TYPE in the values as well as the sliders...o well..
Anyone have the equivalent stock values for this(CM7 stock kernel)...I flashed the glitch kernel and was very put off by the ugly warm color scheme....what was wrong with stock colors any way...IMO they should have some Presets, like Stock, Cool Warm, Standard...kinda like they do for desktop monitors..

We all know that some of the color looks washed when we watch in a diff angle , also the head on looks sometimes may not look great since BE2 is not applied all time .
not sure if this works as I dont have a rooted phone ( dont plan to root till 4.2 ) can anyone test this on their rooted phone and post results and reviews please?

If you just want to deal with the view angle problem, set the system brightness higher (80% or higher), and set the brightness of the screen adjuster to 50%~70%, nothing else. Then the view angle will be amazing, but you will also find very little blue tint when displaying white color

i9505 Color issue - black isn't black on some devices

Hi all,
i bought a I9505 16 GB in germany and after some hours of testing i found an
issue with the screen color. It seems that the black color (OLED pixel should
set to off) aren't set to off. The color looks like black with 5 % red brown and you
can see it in dark ambience with large black area (e.g. ScreenTester )
I changed the device to another one and saw the same problem. But this time i get
an OTA update. After the update (the last for germany i think MDM ) the problem
is gone. Ok now i know that the problem isn't a not fixable hardware problem or
only a software problem...
i startet some test...(i didn't change modem and csc)
1) flashed a costum recovery -> black isn't black in CWM and Touch
1.1) created a backup from stock rom
2) flashed CM 10.1 (build from 19.5) -> black isn't black
3) restore backup from stock rom -> black is black
4) flashed a the omega rom 3.0 -> black isn't black
4.1) flashed the adam kernel 1.2 (with update 1 from samsung) -> black is black
-> The fix/cause for my problem is placed in the kernel.
Maybe the kernel developers can check what are the differencies between
the kernels and update the kernel sources from modded stock Kernels, CM,
CWM and so on...
big thx
its a known bug and you have to update your firmware to the latest version to fix this. i had this bug earlier and after an OTA update its fixed, it never showed up even with custom kernels(9500), not sure whether the kernel sources for 9505 has the fix included...

mhm, so it seems that many kernels sources which are used in cwm, touch recovery and CM doesn't include the fix.
Is the fix delivered by samsungs update 1? because the adam kernel which use this update doesn't have the bug.

Not sure about that - but I wouldn't take notice of the blotches/lines you can see in dark room low brightness. And from what I gather it's gotten much less worse on S4

Gpad screen gamma is too low

Some of you may have noticed it's difficult to watch dark scenes in movies on the gpad. I think the problem is the gamma calibration, you can see it clearly on the pictures I took.
https://imageshack.com/i/nf96iaj
On the top you can see my nexus 7 2013, you can differentiate all the shades of grey from 1% white to 100%.
On the gpad, everything is solid black from 1% to 12% of white.
You can find the original image here : http://imageshack.us/f/594/6291.png/
How low can you go, on your gpad, before the grey melts with the black ?
Do you know an app to apply gamma correction ?
Here you can see the same picture on the N7 and the gpad. You can't even distinguish the guy's ear on the g pad.

I see the difference, and I knew it was there already also.. I'm sorry, but apparently gamma is not something that is doable. - I was looking to link you the app from market called "Screen Adjuster", however you want to look at this description, especially the last sentence. ;/
- dimming the screen 15-100% (below minimum system brightness)
- screen color and a contrast adjustment
- system brightness 0-100% adjustment
- functional widget (on/off, system brightness, settings)
- autorun option
Some phones have a color tint screen. This app have a possibility to try to improve colors on this kind of the screen by setting an additional factor RGB.*
The range of the dimmer is from 15% to 100% (it allows to dim the screen below a min system brightness value). Make a relief for your eyes during a nightly reading.
Furthermore, you can change fast the system brightness too.
The additional contrast factor can try to make the reading or a picture viewing more comfortable on some screens.*
The widget provides fast on/off service with a shortcuts to the Adjuster settings and the system brightness settings.
The application has the autorun option which works with the dimmer set above 22% (for the safety).
Note
A gamma adjustment is not possible to do.
You can of course try and download the app anyways and see if contrast or brightness will do anything for ya.
- In case you do download the app, remember that setting contrast low will result in problems with installing apps, as in you cannot hit Install, only cancel. To avoid this, open up Screen Adjuster and turn it off, install the app and turn it back on afterwards. It's something about lowering the settings to lower than what is "intended", I don't quite understand it and I find it rather odd. But it let's you install apps.. So I guess hooray.
That's all I got.

That's all I got.

Thank you for your response, but I'm already using screen adjuster. I set the contrast at -25 and it helps a lot to see dark details.
Unfortunately, it has two side effects :
- it brightens the dark shades of grey, but also the black levels.
- I noticed that the contrast setting also affects the white making it look like light grey.
So the contrast setting in screen adjuster doesn't affects only the dark tones like it would on a monitor or a tv, it affects the contrast ratio.
I've found apps to make gamma adustment but it only works on some devices with custom kernel.

Yea, I was about to say that gamma can be done but only on custom kernels. Lot of Nexus 5 stuff on the market. Apparently it's Google who locked the gamma settings completely down but only in 4.4.2. I guess it may work on stock LG Kernel since it's only 4.2.2? I'm afraid we'll have to wait for some kernel support for other roms. That would be awesome. I really hope for some Franco-kernel-glory on this device.
That's what I thought, we need to wait for custom kernels...I hope it will come soon, because it's so frustrating to have such a good screen with bad calibration !
People tends to complain too much about the warm white balance but the gamma calibration is far more concerning.

I hope @dalingrin can cook something up to address both. He said he was going to work on something.

Yes it would be great if he did , though he's done so much for us already.

I see someone had developed a nude kernel for our devices. I welder off they can add support for gamma adjustment

Hi there Young Bobbie, I am new to posting on XDA so I couldn't post this in your kernel developer page. This is my first post on any forum page ever. First off, thank you very much for your hard work to make this kernel happen to correct gamma on the v500. I have been sitting on the fence whether to get the gpad, and if i would get the v500 or the v510. Was leaning toward the v510 because of Sleekmason's wonderful kernel work, but it's exciting that we have now have the same options available for the v500. I noticed this was working fully with the Malladus ROM. My question to you was whether or not this worked with stock LG ROM as well? Thank you again YoungBobbie and Sleekmason for your time and creations.
Sorry, just answered my own question. Guess it helps to read the very first line of the page (making fun of myself now ;-P) Thank you again YoungBobbie and sleekmason!!!

Gald to have helped would you be willing to try the kernel for the stock LG ROM?
Please take a look at the images below and compare
The tablet on the right is running my kernel and the left stock
You can see the differences on the first image as the deepness of the blacks
and on the second the highlights on the white

Be happy to. Have to acquire the device first, which will be in a matter of a week or 2
