Has anybody seen an icc profile for this or any other amoled display?
If not, does anybody have calibration equipment or know what the equipment is called to generate an icc profile for under $5000??

Sorry I can't help but @supercurio maybe able to point you in the right direction: http://forum.xda-developers.com/member.php?u=2617206
No sorry no help from me, I use this as a quick display while on shoot to get a general idea of my shots, I have a screen calibrated at home that I do my edits on.
This would be cool, not sure if its something i would use as i am a casual photographer

One gripe I have with my Nexus One is the inaccuracy of the colors on its screen. They appear oversaturated esp. with the reds.
Is there a fix for this or will it be possible that a firmware update may fix this in the future?
My understanding is it could be trivially fixed with a firmware update. I think the reason none of the modded/third-party kernels have done is is because it would require special colour measurement equipment, and (given that the technical docs for the AMOLED are not publically available) quite a bit of patience.
See http://android.git.kernel.org/?p=ke...74950cb35551;hb=refs/heads/android-msm-2.6.32
-- you can see the RGB gamma tables. Tweaking these should be able to change the saturation, colour balance, colour temperature, and theoretically (mostly due to changing the color temperature) improve brightness and display life.
One disadvantage of AMOLEDs at this point in time [since they are relatively new] is the software isn't exactly up-to-date with the hardware... and like @hugonz, we need to have info abt the hardware to tweak the software...

That's not exactly what I said; it would be easier with hardware documentation, but the table looks pretty self-explanatory to me (for each brightness level there is a 7-point gamma curve for each of the R, G, and B components). I haven't yet rooted my phone but it's something I'll definitely look at doing once I start working on kernels (assuming no-one else does it first). Maybe I should try plotting the curves to see if that would inspire any kernel devs to try hacking on this issue now.
@hugonz, I understood ur point... but for us it's more a trial and error effort... and different AMOLEDs probably have different tweak values...
Well I hope it gets started as soon as possible.

Hello
I have a Samsung I9000 Galaxy S which is way too bright even at the lowest setting.
Anyways so I got an idea of an app but I dont know whether its technically possible or not!
So is it possible to create an App that works just like a transparent dark glass which covers your screen and you see through it and can perform all functions normally but due to the app the screen becomes dark so that it doesn't strain the eyes?
Also current "minimum" brightness on the Galaxy S is "10" even with 3rd party apps. Is it a limitation of Android or Samsung firmware? Also is it technically possible to go into - values such as "-30" ?
Ah, great topic. I have the same problem on my HTC Desire. Interesting to hear what the experts have to say.
Yeah these amoled screens are uber bright!
Download AdjBrightness from the market, it rules.

I have read on the net that it doesnt work for Galaxy S.
The app is called screen filter. Don't really know too much about it other than it works fantastically well and its free. Reduces brightness to almost nothing if you want, and the app functions as a widget for toggling as well.
I've been going around posting this in as many places as i can because this freaking app really helped me out, I could hardly look at the screen in the dark at all but now its good to go. Hopefully help some new galaxy purchasers out.
You can't go into minus values but you can set it to 0, which is 1 above the screen actually being off.
You need to be rooted, then you can just adjust the value with adb.

Hi everyone!
maybe you noted that the lg screen is too bright! even in low setting it is almoust unusable in the dark (night)!
Is there someone who knows a way to change the value of brightness of the presets (maybe a regystry tweak)?
I thinks it will be usefull for a lot of people. . . thanks for the help!
I find the low setting to be... quite dark.
Perhaps try setting your theme to Black instead of White...

The low setting is dark in a bright place of course. But if you are in dark, the lowest set for becklit, is too bright. I'll post a link with technical conparison between screens.
here is the link with some data:
http://www.anandtech.com/show/3982/windows-phone-7-review/28
I'm bothered by this too. Does anyone know how to set it to a reasonably low value, so that text can be easily read in the dark? (white text, black background)
I found something in the registry related to brightness, but it seems to be already set to the lowest value (0).
HKEY_LOCAL_MACHINE/Drivers/BuiltIn/Backlight/MinBrightness

Have you tried setting it to a negative value?

Just bought it,and i noticed this too high brightness too...any way to adjust it?
Same here. This is really starting to bother me...
I've already tried messing around with several values in the registry values with no luck... I suspect this can only be solved with drivers and/or firmware. Maybe if enough people complain about this they will change it in a future firmware?
Lg can solve the problem

Exactly! I phone my local support and said this and they were really happy to have a customer feedback.
thay said that they are collecting suggestion and than they will evaluate for a firmware update...
maybe we should suggest to implement autofocus (or prefocus at least) in video too!

Done.
They told me no one had reported about this issue yet, and that they would call me back somewhere over the next few weeks, after their engineers discussed it.
In other words, we need a lot more complaints to achieve this...
(Bump)
Out of curiosity, has anyone else done the same? Several people complained here, but this topic is now suspiciously quiet...
You guys sure you don't have the Automatically adjust setting ON?
Stupid question I know, but I need my 8 posts to post links for my mini PDAir LG Optimus 7 Aluminum case review.
Agreed the LG screen is ridiculously bright on both the Lo and Automatic setting in darkness.
I can't use it in bed as it lights up the whole room, and it causes far too much glare in the car at night so no good for SatNav etc.
Surely it would be better for battery life too if the backlight wasn't burning a hole in my eyes!
Data from link above. Obviously LG need to recalibrate their presets:
Brightness Comparison (White Point)
Phone Low Medium High
HTC Surround 10.4 nits 183.1 nits 405.7 nits
LG Optimus 7 130.4 nits 259.1 nits 381.2 nits
Samsung Focus 61.9 nits 143.1 nits 234.3 nits
LG Service Sites - email your local office to request a fix:
http://www.lg.com/global/supports/service-sites.jsp
Don't know if they will bother fixing this on the E900 (here's hoping) although you would expect it to included in the refresh Mango E906?
Did anyone of you use the amazon Kindle app on lg optimus 7? You can adjust the brightness so damn low within this app...
Dear all so I do a bit of reading laying on bed and lower the brightness levels to the lowest level but the nexus remains too bright. What app are you using to lower brightness further, am rooted running a stock 4.2.1rom please
Get a good reader app, like Moon Reader+.
It has a variety of night settings, like brown ink on a black background.

My wife used to complain about the brightness of my tablet while she was trying to sleep. I found a simple solution...I divorced her.
Nah, I'm kidding, we are still happily married. I use Aldiko Book Reader and set it to white text on a black background and that has pretty much resolved the issues.
Some kernels, like metallice's M-kernel and clemsyns battery saving kernel actually allow the brightness of the screen to go lower than on stock. Like, REALLY low

Is there a web browser that allows to set all pages that are normally black letters on white to the opposite (white text on black)?
I don't know of a browser, but I save articles from the browser to Pocket, which is set to white on black for late night reading

I think a screen filter is the way to go. This one lets you adjust rgb, just set r,g,b to their lowest and set the filter to it's highest.

On a weird note, I was seeking this app out because I saw an interesting episode of the nature of things. It's a canadian show so some might not have heard of it. This episode was called lights out, it described the health issues people have by simply being exposed to light (from electricity) that we wouldn't normally have been, because as far as man goes, electricity is a recent phenomenon. Anyway, it seems not all light is bad, for example exposure to light sources from a flame at night (as our ancestors would) does not have this ill effect. They were basically saying it's light in the blue spectrum (similar to the day sky) that affects our production of melatonin and can give rise to cancer and other ill health effects.
It's may sound silly but the episode had me thinking to lower blue light spectrum from electronics at night before going to bed.
The episodes live stream but I wanted to watch them on the subway. They are an rtsp stream for mobile. I was hoping vlc for android had the ability to record an rtsp like it's desktop counterpart but it doesn't. What's the point of vlc on android if it loses the bulk of it's features? Does anyone know a way of capturing an rtsp stream? I know of linux utilities that can but the rtsp stream address comes out fairly convoluted and I think it redirects to the actual stream behind the scenes.
They don't stream to the US, but if anyone wants to check out the episode I'm talking about it's here:
http://www.cbc.ca/natureofthings/episode/lights-out.html
And if anyone has a way of capturing these streams it would be greatly appreciated.

+1 to Lux. Worth the cost, and fixed (masked) the screen flicker issues I was having from the WiFi ground.
Anyone notice throttling on the screen in terms of contrast tone and brightness. You cannot turn it off no matter what settings you choose. One good example is when you pull up the keyboard and the brightness is fairly low, there's a huge color shift that pops up till the keyboard tray is gone again. Could a kernel fix this?

i am trying to get some help from international model guys on this; mine DOES NOT change contrast and brightness if i disable every auto feature AND ALL POWER SAVING features. I have seen this on another GS4 and not on my own or my GF's with everything disabled. I wonder if there is a difference in screens or part batches and sensitivity or a different controller chip; another thing im looking into.
also the ambient light sensor; try covering it completely. i think that and the 'auto detect/modify screen contrast/colors' is running no matter what on certain GS4's.

i have calibrated many monitors before; maybe when the bootloader is unlocked and there is a full ROM dump someone could assist me to find the screen calibration adjustments so i can create a professional AdobeRGB and sRGB profile for the screen as well as rec 709 full and 16-235 video modes etc. I am not the only one interested in this; the Galaxy S III, Note II, and Google Nexus 7 are all excellent candidates for field monitors with excellent gamut. I just want mine to display colors as accurately as is possible for the moment; i keep all my demo reel footage and music videos i shot on it; a proper 'flat' image is important before editing, and my company we shoot raw, yet even a simple 8 bit example of before/after editing in raw environment would help our clients.
This is the first mobile full HD screen capable of such broadcast range of gamut; would be incredible to use as proper field monitor with correct calibrations.

I think you should set its original setting then your issue may remove
