The Instructions:
Short, sweet, and straight to the point: So, here's what you do... you will want to download the app called Screen Filter with the market link provided below. After you do that, within the Screen Filter app you will want to drag that brightness bar to say 85.1% and then hit enable. This won't lower your current screen brightness very much so no worries there. You should hopefully notice a difference for the better all around, especially viewing from an odd angle. It helps to reduce that white backlight look you get from a side view. I will typically set the in app brightness to either 85.1%, 75.5%, or 72.5%, and my actual system brightness to 50%. It works quite well without being too bright or too dark. And it goes without draining much, if any battery life. Feel free to try other brightness settings to fit your personal needs.
Try it on other Android devices as well, it works great! The best way to test it out is to use the widget. You can turn it off and on while changing your viewing angle to compare and see the difference for yourself on your homescreens. Forget about a complicated method and get yourself a better screen today with Screen Filter!
Screen Filter Can Be Found Here:
https://market.android.com/details?id=com.haxor&feature=search_result
Showing Off Side Angle View:
You will be able to notice that in the after screenshot the green bar across the top of the market app is quite a bit more vibrant and has more of a green color than the before screenshot. And you will also notice that the white back light color will be enhanced as well, giving a better appearance from the side viewing angles. A nifty little quick fix, if you will.

Screen Filter Known Issues Reported By Users:
*Being completely stock and using the stock system apps seems to be causing some major lag issues (Xoom)
*Cannot seem to click install when you are manually installing an apk without disabling (Xoom)
*Cannot compose emails without disabling (Nexus S)
You can add to this list. If you find anymore issues please post them here and I will add them to my list above. After we gather most/all issues that we are having I will let the dev know what we have found and we can make some positive results for all! Maybe we can even have some new features added in a new release. Once the Honeycomb source gets released and we start getting custom ROMs, expect user interface tweaks such as what you find in Cyanogenmod. Until then, use this. It's the easiest and best tool we have for now.
Note For Screen Filter:
This method may only be effective on the 3G version of the Xoom. It appears that it may not be noticeable as much, if at all on the Wifi model.
Make That High Def Screen Even Higher:
For this you will need to be a root user, and always be sure to have a current Nandroid backup handy just in case.
You will want to download the free app called LCD Resolution (Root). You can find it on the market here. Open the app, and then you will see your current density setting as well a list of density options for you to choose from. The default density value for the Xoom is 160. I do not recommend that you go below 140, as certain screen elements may become misaligned. Just dropping the value down by 10 to 150 makes a nice noticeable difference.
Basically: The default density value for the Xoom is 160. I recommend using either 150, or 140 as your density value and nothing less. I think 150 seems to be right where most people would want their screen to be if they wanted to go just a bit higher def. It makes the resolution a little nicer without going too overboard. After you choose your density setting, don't forget to check the "Always Set on Boot" box. This makes it so much easier so that you will not have to worry about setting this up with every single time you boot. Then hit apply, reboot your Xoom, and then make sure that the settings stick. Done!
Apply one of the density settings I have listed with one of the Screen Filter settings also listed for a nice effect. It's almost as if you have a whole new tablet when you combine the two!
Currently: I am using the 140 density value on my Xoom, and I couldn't be happier!
Default Density Value 160:
Density Value 150:
Density Value 140:
If these tips have helped you out toss me a thanks. If I get more positive feedback I will be adding some more great helpful tips for us Xoomers. Thanks for stopping by!
Thank you for a great tip. My Xoom screen look better now. This is why I love to visit XDA everyday.
Will check with Acer A500.
im not really seeing a difference.

The difference is there. Try viewing from different angles instead of straight on and compare. I added my own screenshots of my Xoom just now and you should be able to see a nice difference from the before and after. This method really helps the side viewing angles a lot by reducing the white backlight that causes the screen to distort when not looking directly down on it. But it looks really great all around, not just from the side.
so what do i put the system brightness at? and what do I put the screen filter percentage at?

You can customize and set it to whatever you like. Me, for normal usage I like to use 50% for the system brightness and 85.1% for the Screen Filter brightness. I think it works quite well this way without being too dark or too bright. I use this setting on both my Xoom and my OG Droid.
I see what your saying, the viewing angle is alot better now, thanks OP
wow, makes a huge difference for me, thanks
How does it impact battery usage at the 50/85?

It really does not impact the battery life very much if at all. In fact it possibly might save a little bit of battery life if anything. I've been using this setup for months and it has been working great.

Hmm.. interesting. I use it all the time without any kind of problem. What launcher and browser are you using? And are you stock or rooted?
I'm using both Adw Launcher and Launcher Pro depending on my mood and they both work great with Screen Filter enabled.. no lag of any kind. And my browser of choice is always Dolphin HD and it also works without any lag. I'm on a rooted 3.1 Xoom with the latest tiamat kernel. Maybe I can help solve the problem?
i am curious why one would jack their screen brightness up to 85% in the first place, 33% gets a perfectly view able screen indoors. Not to mention the savings wrt battery life.

Yep, nice for off angles but for sure adds all types of lag. Bonse stock 3.1 no root. Factory launcher... isn't their a color control like what's available for the Nexus S? You would think with the screen wash out complaints someone would have come up with an answer by now.
Just tested another app. Really liked the effect on off angles so I'm searching the market for other stuff. There is another app called back light filter. It alowsyou to adjust the Alpha levels along with individual colors. Have to tinker to find the best fit but no home screen lag.

I've tested this app before and it's so so. Most users will want something easy to use without much tinkering or setup. It works pretty well through, but it could use some more features, it lacks a widget, and there is no notification bar icon for fast access. Good comment though. Maybe the people who are completly stock everything should give this a go since they are reporting lag issues.
I don't see any difference.

I agree with you on the simplicity of the app in the original post. If the developer can dial out the lag it is definately the best tool for screen filtering on the xoom. I just wish the OEMs would provide simple calibration tools for screens.
I just tried the latest Samurai kernel with Voodoo Color and I am not a fan. I know a lot of people love it but personally I don't. At first boot your phone is dim. Then you have to download an app to set the colors. I tried several people's suggestions and didn't like any of them. So there is constant fiddling to get the colors the way I would like. Plus I had to turn my display up to about 35% when normally use about 15%. That has to eat up more battery, as well as constant adjusting. Then between the kernel and Voodoo app I am down 30 MB of RAM then what I normally have. I know for gaming it is probably the shizzle but for just a phone and browsing, not needed.
I flashed back to Samurai 2.08 and phone looks great still, lower screen brightness and actually is faster. Not sure if that is the kernel or lack of voodoo color.
Just had to get that out. I am sure this will open up a pros and cons discussion of voodoo color. I guess this would be a first edition of Kenny's Blog...LOL.

I dont really care much for it either. Whenever I start up a rom with a fresh voodoo kernel, the screen is piss yellow. I have tried a few different setting suggestions, but the screen is always way too blue. My friends drewl over this super AMOLED screen without doing anything to it.... i kind of agree with them.
Meh I tried it, thought itd be sweet, but not really lol. Using chainfire is better (Nightmode). Voodoo color is fun to mess with, for a few minutes XD

I agree. Didn't see significant benefit to having it either! (On the Epic) I think it can make a huge difference on other devices though, from images I've seen. Not to knock the Voodoo team as their work is awesome.
I AM a fan of CM7's RenderFX (and widgets) that can make the screen go all green or red or low cal night mode (and more) - each with a single toggle - is pretty damn sweet!
My feeling on this is if you need a program to custom tweak the nominal display colors as if its a high end digital cinema: maybe you got the wrong phone.

I like it, it makes my blacks blacker, and my whites whiter... as for the resources it takes, that I do agree with, not that it takes a lot, but 2.0.8 was a little quicker for me. I keep my phone at about 5 - 10 percent brightness all day. I think it looks nice though, personally I feel it is better then stock. And if you are getting the yellow stuff on boot, or on dim, probably have the wrong settings.

@kennyglass123
I've been tempted to post the same thing, but I assumed I must be doing something wrong because everyone else seems to love Voodoo Color. I tried every combination of settings that have been posted (including those above), and though they may add some punchiness, the colors always seem to be very unbalanced/inaccurate (either too blue, or too yellow, or too something else I can't put my finger on). I also tried dozens of my own combinations, just can't get it set to anything that doesn't end up bugging me after a while. Oh well, I'm going to follow your lead and flash back to 2.08 for a while and see if I miss Voodoo.
I like my phone really dark, and that might not be for everyone
Some of this may be due to inevitable inconsistencies in these screens of ours from their factory days. But I find VC to be preferable even at defaults. Colors seem much truer and the nasty bluish tint over much of the screen is lessened.
I love it. Not sure what it's doing for everyone else that doesn't seem to be causing a problem here.
Here are my settings, took me a bit to get my screen to where it looks best for me:

Wow.. are you reading my mind? I flashed it and ran for a few days. Even a very non-technical co-worker saw my phone and asked if my screen was going out since the colors looked weird. She always commented on how beautiful the screen looked.
Had to crank up my screen brightness turning off auto-brightness as well which is killing my battery.
Soo..what's a stable Samurai to go to? I'm not interested in voodoo, oc/vu, just plain ole I want my daily driver to work.
2.08 is the recommended stable replacement according to Earthbound.

I wouldn't call it a problem, just like I said, not a fan. I tried several suggested settings and no matter what on some screen something always seemed off. That and having to crank the display brightness up is just not for me. I am real happy with the beauty of the stock colors. I see the potential for the voodoo color but it would take too much work and adjusting until I would be happy with it.

im running Marcus's rom, which comes with sam 2.06.
I tried flashing the new sammy colonel last night, and aside from the fact that the colors looked piss yellow, it was really laggy.. to the point were i reflashed the rom to get 2.06 back.. didnt really see that coming
Also, Im not really sure what everyones talking about with the "blueish" tint of the stock colors. I held my epic up to my GFs Moto Atrix, expecting to marvel at how much better my samsung screen looked, only to find that (even on the stock, non-VC colors) it looked piss yellow compared to her moto.
So, aside from not wanting to have to eff with the color settings, the main kernal right now that has it, apparently, hates my phone anyways

Only on 1st boot and look. Then I saw everyone using the 2nd profile and tried all the settings I can find. There was always something off, one was too blue, one was too warm, one was too brown, and all were too dark requiring at least doubling my normal brightness setting which uses up more battery.
I would spend time tweaking my TV a little but don't want to keep doing it for the phone. It is awesome that it is better than sliced bread for a lot of users but just not for me.

Sent from my Legendary 2.2 infused device.
I have installed Paranoid Android on my Note and noticed that there is severe clipping in the CM9 UI elements. Even the default ICS wallpaper , the one with the"rainbow" coloing stripes show severe clipping on the lockscreen. It looks just plain ugly. And since most of the CM9 UI backgrounds are a shade of grey, there is severe clipping of these grey elements to a purplish pixellation and to black. You can notice this if you take the settings page in Paranoid android or any other CM9 based ROM (assuming most CM9 based ROMS have the same default theme) Look under the status bar where the grey background fades to black and you may notice severe pixellation like issues at that area. Now, go to advanced, screen settings and MDNIE mode, you will notice that the clipping keeps changing when changing modes but its still there in every screen mode.
How many of you are experiencing this? Assuming a majority of the people who run Custom ROMS run a CM9 based ROM, why isnt this issue reported anywhere? I'm asking because, the issue is plainly visible in these grey areas and UI elements making the visual experience really bad. And why is Gamma Control disabled in these CM9 kernels? I believe lowering the gamma would solve the problem.
I've noticed that CM9 kernels have the worst clipping whereas in other stock based kernels, the clipping is comparitively lower, closer to the stock kernels.
So once again users of CM9, please do report if you face this issue.
CM9 users please report back because I havent seen anybody talking about this issue in any of the CM9 related ROMS thread. People seem to ignore an issue which stares back right at the face even in ambient lighting. Why havent this been reported?
I dont have much idea about who develops CM9 kernels for the note. How can we contact the CM9 developers and let them know of this issue and request to enable Gamma Control within the kernel?
Somebody please help me out here. Because its been a month after I bought my note and I've been struggling and doing my best to find a solution to this horrible clipping. I had got in touch with GSMArena and got this issue published, yet Samsung never responded, I tried kernel after kernel and realised that the intensity of the issue varies from kernel to kernel. I've seen that whomever I ask about the clipping in this forum says they have it but then everyone seems to be happy running different ROMS and in these CM9 based ROMs which look as close to stock Google ICS UI have severe clipping all over the UI and yet people dont seem to bother.
So what can I conclude from this? Is this an isolated issue or are all of you Note users who have this issue just keeping silent and living with it?
I do not mean to spoil anybody's peace or anything. I clearly dont know how to get in touch with the CM9 devs for the Note, somebody help me if possible. And if you feel that this is an isolated issue, do let me know otherwise. Because, when the basic UI shows severe clipping, the whole user experience is spoiled and nobody wants to live in fear with bright UI elements and bright wallpapers dreading the clipping if anything at all has to be dark. We paid a premium for this device and even Samsung seems to ignore. I have the SGS3 and there is no clipping on it but just that everything seems darker on the GS3 when compared to the Note. This alone shows that Gamma is a culprit here and I could just sell away my Note and just live with the GS3. But that doesn't help anybody who is facing this issue and wants to see a solution. Even I personally like the note more than the GS3 and I want to keep it but for this issue. Not everybody has the money to jump to the next flagship every now and then and for the people who spent their money on the Note doesn't have to "live with it" just because they decided to buy it without knowing such an issue existed. Not every store lets you try and trial their devices before buying them.
Samsung has even seemed to ignore the EMMC issue even after claiming they are "working on it" I dont see anything productive from Samsung's side as even a device which was previously unaffected had the affected kernels pushed to it via an update. So basically if it was not for people like Entropy who works day and night for that issue, Samsung could keep replacing motherboards for every random wipe a user does. They basically want to sell the note until the Note 2 and then this wouldn't be their problem anymore. Problems like the emmc bug is a MISTAKE from Samsung's part and they should be ready to repair devices even beyond warranty as the user may have only done the most harmless thing, i.e to reset the device to factory settings.
So, coming back to topic, how do we get in touch with the CM9 devs and enable gamma control on these ROMs? Most ROMS have gamma control under MDNIE settings which is greyed out, most probably because the kernel doesnt support it. This is the best I can do for the people who are affected by the clipping issue as I'm not a developer. This issue isnt an isolated case in my opinion and affects every Note I've got a chance to see.
It might help if you actually posted requests in the cm9 discussion thread? #commonsense

Yeah. OP is TL;DR complaining about some "severe" issue I've never seen and no one else has.
As to gamma control being disabled - I should remove that from the settings app, as that's something supported by the I9100/I777 display driver but not ours.

Oops..I'm sorry for the long post. Its basically about the severe "black clipping" which has been affecting the Note since release. This issue is best seen when displaying dark shadows in images and videos. There were many threads discussing this issue. And GSMArena had published this issue in their news after I mailed them about the same.
What I wanted to tell was, I feel this is caused by the Note's screen having the gamma cranked up quite high and I believe lowering the gamma would resolve this issue.
The default CM9 theme shows severe clipping in backgrounds and UI elements. All the grey backgrounds, (the default theme) clip to black just below the status bar.
Even all the videos which have dark shadows are totally blocky due to this and the clipping makes them literally unwatchable.
I had reported this issue to GSMArena
http://www.gsmarena.com/samsung_galaxy_note_plagued_by_display_issues-news-4513.php
I wanted the Gamma Control feature which is presently disabled to be enabled in the CM9 kernels so that we can tune down the Gamma to eliminate this clipping
The same issues existed on the GNexus and was fixed with the Lean Kernel which had Gamma Tuning.
So once again, in short, I'm talking about the "Black clipping\crush" on the Note when displaying darker shades of colours.
All the notes have this problem, and we need to access to gamma control but as supercurio said it won't solve all the problems of the black clipping and banding issues

Satishp, i know what are you talking about. Just take a picture of your note and post it here. Of course, you won't use a screenshot feature but a camera.
I sold my note bc of the black clipping issue, but now I cannot buy an s3 or HoX cause their screens are just to small, that is, narrow. Gonna buy Note again and hope some solution will come out. It is too bad to buy a phone for its screen and get a crappy quality. Issue on s3 is solved with lowered gamma. Comparing with the Note, s3 has much darker screen. Sometimes too much.

All of the speculation and misinformation of this issue is really starting to get frustrating. First, the issue IS with the hardware. It may be possible to reduce it's impact using software but the fact remains this is a hardware issue. How do I know? I have replaced my Note's screen and the newer screen I have isn't as good as the old one.
The new one isn't awful, it simply isn't as good as the other.
2nd point - everyone will have this issue. It is simply an inherent problem with the screen hardware and it is completely implausible that there are 1 or 2 'perfect' screens out there. There will simply be variations. Some people WILL have better screens than others. For some people the issue may be completely unnoticeable and for others it will be glaringly obvious. Don't judge or hate on people because their screen is worse than yours and vice versa.
3rd the issue is MORE noticeable at lower brightness values than high brightness values. If you have your note on higher brightness values then you're unlikely to notice it. In my case, I can not see any clipping if I am in a lit room. The only time I can see it is when I'm sat in the dark with very low brightness. As I said above this will vary from person to person.
I have attached 2 photos below. One is a normal exposure where you can see the clipping is hard to see. Another is a long exposure which amplifies the issue more and makes it more noticeable (I used a longer exposure on my camera to show this). Fortunately it isn't so bad for me, but for some people my long exposure image is the reality unfortunately.
Standard: http://i48.tinypic.com/4uxnia.jpg
Long Exposure: http://i48.tinypic.com/5akew3.jpg
Why have we got a clipping problem and can software solve it? I believe it is highly unlikely that this issue can be solvable. I also think the issue stems from one simple shortcoming to the screen; the minimum brightness achievable per pixel. The problem is the jump from this minimum brightness to the 'off' (perfectly black) pixel is too great. There is no transition. Can gamma control solve this? I'm not convinced. I think the issue is more to do with what the lowest pixel brightness the screen is capable of. For the poorer people this minimum brightness will be quite bright. For others the minimum brightness will be lower.
If any devs know of a way of controlling pixel brightness on a level where it can be noticeably changed and if it is possible to reduce this minimum brightness then sure, it would certainly be a possibility. But I don't think this is possible.
Part of this might be a limitation of the HD Pentile AMOLED technology. But if you notice, both the Galaxy Nexus and the Galaxy S3 share the same technology. For people who argue that the S3 uses a different manufacturing procedure, Samsung has no where mentioned this and its just an assumption.
The GNexus had the same issue but was solved with the LEAN kernel which implemented a gamma control within the kernel. If you've seen the S3's screen ( I own an S3 too, So I've spent a good time comparing), you will notice that the S3's screen is visibly darker than the Note's screen. Images tend to look darker and this shows that the S3's screen has its gamma set to a lower value which eliminates the clipping.
More proof for you, lets take the gammatest image and view it on our PC. Most PCs use an LCD display and still you can see the greys gradually fading to black.
Now increase the gamma of your display from your display adapter's color settings and view the same image again. You will see that you can see all the way upto 1 and then black just like how the image is displayed by the note.

Now view a 720p or 1080p clip on your PC with the gamma values still high, you will see the clipping in every dark scene. Try it yourself.
This shows that gamma calibration can correct the issue to atleast some extent.
Hmm. There appears to be truth in what you say. Unfortunately the Note is lacking somewhat in the developer department. And the few devs there are have other pressing issues to deal with so the question becomes who can implement gamma control on the Note?

Huh?
Everytime I turn my screen on I smile at how awesome it is..Hell it seems even better now that I have been using cm10 but i think thats just because its brightness seems to be overall set higher.

Yup. Despite being pentile, compared to my I9100/I777 the screen is even more gorgeous.
I'm on minimum brightness nearly all the time. No clipping issues whatsoever.

Yup, and it's even better when you switch the screen mode to "Dynamic" (Advanced Settings).

I have the clipping regardless of which mode I put it in, apart from the clipping the screen is mint, which makes me even more pissed off when I watch a movie and a dark scene comes on, then the shade between black and grey turns into a lego block mess. I really cant beleive so many people are happy with it, half of u guys must be blind, I exchanged my Note twice, tested my cousins and my bosses Notes, all have the exact same problem. I even bluetoothed the gamma test image to a few in carphone warehouse , same with them, even the samsung rep I spoke to over the phone said the one they have in the office also has the issue. Total crap imo, Samsung total FAIL.

I've watched plenty of dark movies... As good as if not better than my I9100/I777.

Please take a picture if your note displaying the gamma test image (blocks numbered 1 to 20) with stock gallery app in a dark room, screen mode dynamic, max brightnes with auto adjust switched off, I bet number 4 is light grey, then number 3 is black, if so your device has black clipping. There should be no abrupt drop from grey to black, it should be a gentle fade.
Thanks.
So as you guys may know the screen gets throttled no matter what. But if you go on aokp the throttling isn't there so does anyone know what makes it happen and if we can stop it on touchwiz.

Im stupid..what does throttle do?
Maybe I have it and don't even know it.
Everyone does its easily visible when the brightness is low and you're on chrome or anything for that matter even YouTube. If you bring the keyboard up you can see a color shift I'm the browser and if you are playing a YouTube video through the app you can see a color shift when you press on the screen while a video is being played. It's quite annoying but clearly a touchwiz thing. You can't even turn it off.

The color shifts a lot depending on what you're doing.

thanks for educating me here....
I just don't see this, could it be I am old and wear glasses
Settings > My device > Display > Auto adjust screen tone. Does unchecking that fix it for you?
No it doesn't. It's integrated in touch wiz
I tried to duplicate and don't see it either--I am old--
I do have tone unchecked though
its dynamicaly adjusting to help you get the best view, i dint mind it at all haha
Actually, I just started noticing this with certain downloaded keyboards as well. I don't remember it happening with the stock keyboard, but I REALLY notice it while using Kii Keyboard in certain apps, but only darkly-themed apps. It's less noticeable with bright backgrounds.
Is it me, or did the display improve? I can see some difference, better coloring and saturation.. Anyone else..

Lol be interesting to see when I update. It is possible they could have tweaked it a little though
Hmm, looks exactly the same to me.
On what color profile are you on?
I think my colors are a bit more punchy and saturated now as well, just done update.
Will check if my GF will see any difference as hers phone is updating now...
When I powered up my brain said, display seems different, but after usage I can't tell anymore.

I think you are right. I've just checked the Electric Sheep wallpaper - it stopped looking like old, worn out, colourless rug.
Colours are the same, no mention of any colour improvements in the changelog anyways.

That's possible, there were about 59 bug fixes from what I read.....One thing for sure that was fixed is the FPS....much better :good:
I can guarantee i can see no improvement whatsoever i am using saturated mode from day 1

I notice zero difference in my case.
Nope screen is still mediocre
I noticed that black crush was slightly better after the March update. Watching the HDR sheep video the dark parts weren't completely black. Also, that black box test I compared what boxes I was able to see compared to others and I was able to see the darker boxes

Maybe they tweaked the gamma . We all know that's the problem

Because before the update the FPS was super laggy, after the update it seems much improved and responsive
I'm on natural color scheme and what I noticed was the black background I use for wallpaper seems, well, blacker. It might not be a color improvement but rather a contrast one...
I agree. I noticed sharper images too
I feel like things look better too.. unfortunately my battery life is awful
