[Android Q&A, Help & Troubleshooting] bolibo:
Having root access from recovery is a must to solve problems if you run into them (run "/system/lib/cf3d_uninstall.sh" as root to remove the driver and restore the old one)

1. boot into jb recovery mode

2. run "adb devices" - to make sure the phone drivers are ok (should output a long hex string and "device")

3. run "adb shell" from command prompt

4. in shell prompt "sh system/lib"

5. still in shell "sh /cf3d_uninstall.sh"

phone will reboot and you have working jb system ;)

- it worked for me but no guarantee it'll work for you!

hope it helps.

guys at first i tried to use adb

i got no permissions

so i thought i can use terminal emulator

first open terminal emulator

write SU and give terminal the superuser rights

now use the command

"/system/lib/cf3d_uninstall.sh"

or

"sh /cf3d_uninstall.sh"

after success

your phone will stop giving orders and responding

now you can remove the battery and you are done

[Galaxy S II General] kreoXDA:
thanks for the post, but what secrets were revealed? Quite possible I am too tired (2 in the morning my time), but I only see thorough measurements here :)

How do you explain color space change and brightness decrease in the weeks you had the phone? Is this how quick the OLED light output degrades?
[Galaxy S II General] puremind:
You ask what secrets were revealed, but then you ask about one of the interesting findings. OLED displays in general are known to degrade over time, as OLED are especially vulnerable to heat.

The degradation you observe is typically more important in the first few weeks of operation, so there is no need to panic. I will continue to monitor this over time and post updated findings.

Why is green most affected? Green is responsible for most of the light output in any display, because it has a high luminance. This is why Samsung's AMOLED exhibits a green push in the white balance, which no other type screen exhibits. Green oversaturation is very hard to compensate with red, and it would likely reduce battery life. You could see green as an economical way of producing more light output at the lowest power consumtion possible.

Balanced greyscale is only achievable if one is prepared to live with a lower maximum brightness on AMOLED's...or insane battery consumption.

I guess, this is the undisclosed truth that Samsung of course will not publicly admit to, but this is what the measurements reveal when you are used to calibrating displays. Basically, Samsung have had to make compromises in terms of white balance and black crush in order to squeeze some extra brightness out of the battery!
[Galaxy S II General] godutch:
I really have no clue what you just wrote in your OP but you seem to know a lot about displays and color. What I do know about the SGS2 is that is shows color banding in gradients maybe you could explain why that happens, is it a characteristic of the display or a software problem?

eg see these threads:

[Galaxy S II General] puremind:
This probably needs to be solved at the driver level, just like the color gamma and white balance issues. This is related and is something that Chainfire could have a look at. That's his domain of expertise after all...

I only calibrate displays. I am totally unskilled as a developer.
[Galaxy S II General] godutch:
Cool so the display is capable of 24 bits color at least?
[Galaxy S II General] MiG123:
maybe u can forward this to supercurio. He has some interest as well as experience developing voodoo color for the last gen samsung phones.
[Galaxy S II General] puremind:
Great idea. I posted to Chainfire already, but Supercurio may actually be an even more natural choice.
[Galaxy S II General] Tinderbox (UK):
This has me worried "Greenish white, which becomes bluish after a few weeks of operation" :(

Is there a bedding in period for oled when they are new, like a plasma tv , that they say to keep the brightness low and avoid frozen images and logos for the first 100hrs until the phosphor settles down.

Hopefully the degradation of the colours will slow down.

EDIT : Also any owners of previous generation oled mobiles, how much degradation of the colours and brightness do they show after a few months/years.

EDIT 2 : It looks like the "Samsung W2400 Special Edition" from 2007 is one of the first oled cell phones , I wonder how it`s display is holding up.
[Galaxy S II General] Chainfire:
This is indeed a Supercurio thing :)
[Galaxy S II General] jvidia:
What worries me the most is the left side yellow tint ... and samsung says noting.

I went for S2 because of the SAMOLED+ screen and now I get yellow tint for 600€ :(
[Galaxy S II General] Isadora:
Thanks for taking the time to do the testing. I'm used to a calibrated environment (I'm a photographer) and I have to say that I really don't like looking at non-calibrated displays of any kind (usually over saturated, too bright and very obvious colour shifts). If anyone can come up with a way of making proper adjustments to the S2, I would be soooo happy :p
[Galaxy S II General] RogerPodacter:
Nice info. Another dirty secret I'm on the fence about is how power hungry white screens actually ate on amoled screens. Look at the test results I did and how power usage spikes to -900 mA just loading a white web page.

http://xdaforums.com/showthread.php?t=998544
[Galaxy S II General] puremind:
I am not surprised. This confirms my theory that Samsung indeed hat to fiddle a lot to contain power consumption within acceptable levels, hence the lack of reds across the greyscale, the black crush we observe without screen power auto adjust and the limited brightness output with it engaged...!

Still, I wouldn't mind having a power hungry but accurate color profile that I can engage only as needed! The screen definitely has the potential. The only question is: at what brightness level is a balanced greyscale achievable. I am betting at around 110cd/m². Considering the true blacks this is very acceptable in dark environments (similar to the best plasma screens), but will not be satisfying under day light conditions, which is most of the time...

Still, I wouldn't mind attempting such a calibration providing the right tool is developed.
[Galaxy S II General] kreoXDA:
I believe the degradation is visible after a month-two, we just do not want to believe our eyes. :)

I think when I first unboxed my phone, it looked so much brighter!

And this is how Samsung is selling us these HyperSuperAMOLED+++ "upgrades" - whenever we look at a new version it is by design looking better than our old previous generation AMOLED :)
[Galaxy S II General] ph00ny:
Which firmware did you have in the first test and any firmware changes prior to the last test?
[Galaxy S II General] ithehappy:
100% same here. Nah, seriously I should've gone for the S-LCD displays. S-AMOLED + is still an unfinished product, under development, unless it comes to the stage of a finished and ready for market product we should avoid it. Thanks to OP for doing some good measurements.

Regards.
[Galaxy S II General] ph00ny:
It's hard for me to judge if i had any screen degradations on my captivate since i had it flashed to a new rom quite often and i never had the screen on high brightness (never felt the need to do so)
[Galaxy S II General] puremind:
Note that not all of the degradation is negative. The alleviates the oversaturated greens, and a bluish greyscale is arguably better than a greenish one.

Also, the brightness is still more than enough and bighter than many laptops even after a few weeks of operation.

I will keep monitoring to see how things develop.
[Galaxy S II General] puremind:
Note that the limitation seems to be the battery rather than the display itself. Also the software is responsible for the presets and lack of controls. When Supercurio comes up with Voodoo for the SGSII, we should be able to rectify most of the issues.

The screen is still excellent for films watched in a dark environment if you keep screen power auto adjust activated.

Bightness can be as bright as on a retina display, yes, but at a high power consumption cost.

This is the next step in amoled technology, looks pretty cool:

[Galaxy S II General] Twister360:
Thanks for the informative post. I like reading 'good stuff'

I have a question regarding your post. This bluish tinte you're describing, is it visible when you hold the display at a 0degree viewing angle, or when you turn the display away from you, thus increasing the viewing angle?

I ask this, because my phone has recently had a swap of displays and it already shows bluish colors when I turn the phone away from me. I'd say at about 15degrees away from the reference (o degrees viewing angle) it starts showing the bluish colors.

I hope you can help me, or enlighten me.

Thank you!
[Galaxy S II General] ph00ny:
Puremid,

I'm just wondering if samsung made any calibration changes in the firmware. Do you mind checking the firmware used in both tests?
[Galaxy S II General] rikc:
@puremind,

Great work! But I'm wondering. I suspect this is about one sample of the SGS2?

If I read the forums I get the impression that there can be quite some differences between phones.

At least I'm not 'expieriencing' any of the typical complaints... though maybe I'm biased because I uses a S-Amoled phone before the sgs2 (the omnia hd)
[Galaxy S II General] EarlZ:
Are all these issues also present to the SGS1?
[Galaxy S II General] crypticc:
Cognition rom promising voodoo colour soon
[Galaxy S II General] puremind:
Same Firmware. KF1.
[Galaxy S II General] puremind:
Like with any product there are production tolerances. However it is not like on some HTC or Dell devices where different screens were built in different countries or sometimes even in the same country...

I have had multiple SGSII devices in my hand and tested 2 of them with very similar results...I am anal about screen quality, all screens behave the same +/- 5% which has to do with measurements and screen uniformity (measuring 1 spot of the screen versus another) rather than different displays.
[Galaxy S II General] puremind:
I do not own a Galaxy SI but from what I have seen on my last flatmate's phone, the screens look very similar. The "Super" is probably more a software preset than an actual hardware difference. But I didn't own an SGSII at that time, so it is still possible I don't remember correctly. But I am training to analysing screens by eye and I think both screens both displays behave the same
[Galaxy S II General] tuhinz:
The 'plus' (Not 'super' which is the S in SAMOLED) actually is different hardware as well. The sub-pixel arrangement has changed from pentile in the SAMOLED in SGS1 to RGB stripe in SGSII.

I have not used SAMOLED before however others have often said that the pentile display is supposedly less sharp (fuzzy text as well)! :)
[Galaxy S II General] puremind:
Most users won't perceive this as bluish, considering this is the standard white balance of many uncalibrated televisions...I wouldn't worry about this too much. 95% of the users probably even prever colder color temperature to the warmer 65K standard...
[Galaxy S II General] ph00ny:
there is definite noticeable difference specially during high def video playback
[Galaxy S II General] puremind:
The impact would be on sharpness rather than white balance or color saturation, though.
[Galaxy S II General] Sleepycat3:
The change from pentile to RGB stripe is the "Plus" in Super AMOLED Plus.

The Super refers to the integrated capacitative touch panel.
[Galaxy S II General] ttl8me:
Wow! With all the scientific data and explanations you posted, I think Samsung should seriously considering hiring you as their display/screen consultant in the future!! :-)
[Galaxy S II General] puremind:
I think Samsung have all the people they need. I think the calibration of OLED displays is complicated by the Power requirements. I think what Samsung need is not more calibration expertise, it is just further customization options and additional presets for those who need it.

The way the screen was calibrated is designed to meet 2 main conditions:

brightness equivalent to iPhone 4

decent battery life

Without those constraints, they would surely have achieved better gamma and white balance...
[Galaxy S II General] puremind:
If there is anyone in Frankfurt with an S1 device, I am happy to do some measurements. This could be very interesting.

I did a bit of reading, and it looks as if there is no black crush on the S1, but also 18% more battery consumption...

Personally I wouldn't mind a more accurate preset even if I have to relinquish some battery time!
[Galaxy S II General] EarlZ:
Do all units suffer the greenish whites on the SGS2, as on the SGS1 not all units had calibration issues.
[Galaxy S II General] puremind:
Yes, unfortunately. It varies from screen to screen slightly. With Voodoo color we should be able to mitigate if not entirely remove this (but this may be at the expense of other display characteristics - contrast for sure, maybe gamma and color saturation...need to see how the screen reacts).
[Galaxy S II General] tuhinz:
Hey thanks.

Had a brain fart moment there! Corrected.
[Galaxy S II General] holgalee:
Wow, all the scientific jargon just flew over my head! LOL. :p

Seriously, Samsung should get this fixed by a firmware. If Supercurio can fix this, I'll be happy to donate! ;)
[Galaxy S II General] angelomaldito:
Thank you for sharing your research results, this is really interesting to know. Just for curiosity, what method did you use in order to find these results, i.e. how did you measure these things?
[Galaxy S II General] puremind:
I used a spectroradiometer coupled with reference test pictures of primary/secondary colors for saturation and color space and 10% incremental greyscale for white balance and gamma.

Unfortunately the blacks are too black to be measured. You would need a 30,000 USD device to measure the blacks of the SGS2 accurately...
[Galaxy S II General] EarlZ:
Its to black but its certainly visible in a dark room, but its a very impressive black.

Whats your take on the yellow tinting, screen defect or glue issue?
[Galaxy S II General] Amenothes:
Wow nice analysis, would be helpful for some devs.
[Galaxy S II General] angelomaldito:
Very interesting, thanks! ;)
[Galaxy S II General] Nu3a:
It would be really nice to have a clarification from Samsung. My friend bought SGS2 a few days ago and compared to my screen there was no tint/darker left side on his device and his screen was brighter on the lowest setting. Maybe the new batch addressed issues with the screen. Any of you guys have some explanations?
[Galaxy S II General] EarlZ:
With "Auto Adjust Screen Power" enabled whites also appear a bit darker. I noticed this when I was viewing my gallery pictures. A simple synthetic test would be to place an all white image in your gallery, then a non white picture before it and slowly slide it into view, as it reaches about 1/2 of the screen thats the point where the white levels drop.

Compare the same image with "Auto Adjust Screen Power" on and off, be sure to press the lock button after toggling it for the settings to take effect.
[Galaxy S II General] cobhc:
@Puremind, have you tried the RGB controls within Chainfire3D? It's basic, but it does allow you to change seperate RGB values for the whole OS, which could maybe be used to correct the Blue push?
[Galaxy S II General] puremind:
Thanks for the hint. I had contacted Chainfire regarding this before I turned to Supercurio, but it seems he has taken this into account and added those controls.

Are they part of the pro version only?

I will definitely perform a calibration and report my findings.
[Galaxy S II General] EarlZ:
Do you have a photo comparison of the black crush, I cant seem to notice it despite how hard I try..
[Galaxy S II General] 666fff:
Hmmm, some interesting comments here...I'm scared to use my phone now...

[Galaxy S II General] cobhc:
I'm not sure sorry.

Please keep us informed.
[Galaxy S II General] EarlZ:
I noticed my my screen as a strong red push, it gives me really good whites and reddish greys, is this also causing my movies to appear darker compared to other phones with the same brightness level.
[Galaxy S II General] AndroidGX:
