Please add the option of modifying auto-brightness levels, like CM 6.1. I suppose that it would require a kernel modification + an app to do this through gui.
Thanks.
What can CM do? I've been thinking it would be nice to be able to modify the min and max, and maybe the curve.

It allows one to arbitrarily edit a table of sensor output vs brightness/button brightness.
It's really nifty.
CM6.1 reports these sensor values:
10, 160, 225, 320, 640, 1280, 2600, 10240
10-160 is in dimly lit indoors, 320-640-1280, in moderately to brightly lit indoors, and the rest is outside.
So I set those to brightness something like 50,60,70,80, 110, 140, 180, 255. A it was perfect to my eye. Not too bright, not too dim.
Didn't ever have to mess with brightness after that.
I'd really like to hear from developers like Netarchy and King, as well as from regular users - if they would like that option.
I would love to see this.
I always feel the auto-sensor tends to be too bright, and never adjusts the screen low enough inside.

That's exactly what I think. Plus, the brightness is not at maximum in direct sunlight (although that might be a safety feature).
Mine always send to bright, or it won't get bright when I go into a bright area until I sleep and wake it. :|

+1 on this. So motivated that I searched for this thread....
Any news?

The stock auto-brightness is way too bright in completely darkness. This is one of the things I had on my list nearly since the beginning. Nobody else seemed to care.

An article showing how useless auto-brightness is:

Do people not notice this or do they just not care?
Pretty sure people have given up on this. It's taken me three days of Google searching to find this thread so people probably don't know where to turn.
The lack of adjustments to the auto brightness values is extremely annoying. Even my old Windows mobile 6 phones had this ability.

There was an application for WM I used to use on my Mogul, cant remember what it was called but it allowed you to calibrate the auto brightness levels. Anyone know what I'm talking about, or if there's an Android version?
This can be done with Tasker in the Market. Its a powerful app and there was a thread a while back about this exact thing. I don't remember what it was called, but I posted in it, so you could browse my posts from a month or so ago.
Hey... This thing makes phone calls too!
Sending this straight back, I cannot believe there is no option to disable auto brightness settings on this heap of ++++.
It has got a mind of its own and is extremely annoying to suddenly see the screen get dim and bright every 5 seconds without any change in actual lighting condition...it makes the phone almost unusable.
Hope someone can make a hack for this soon.

Yes, totally a reason to send it back, software bug on a phone with a unlockable bootloader. Hope your next one doesn't have any real issues
Maybe this was the software bug vodafone was saying?
http://www.google.com/search?client...rceid=opera&ie=utf-8&oe=utf-8&channel=suggest
sure you can't find a solution? It must be somewhere in the settings (I'm no android expert though).
It's not a "software bug", it's SE dictating to us that in order for the paltry battery to last a day, we need to use it in the dark, or disco mode!

... unless the sensor it's self is dicked, then it can be fixed in software, even if it is dicked, it can be completely disabled.... just cool your jets.
well i report no such shinanigans happening on my phone! i can see the light sensor in action when i cover it with my thumb, it works really well and the gradient of fading and lighting up is the best i've seen on any phone so far! i dont notice it when using it normally.
you must have a faulty one....

Can't you install brightness level from the market to controll the auto brightness ?
Wanna control your brightness levels quick and easy? I use a very slick widget called Dazzle. It has every option you can think of to control just about everything on your phone. Give it a try.

A Dutch review actually mentioned a lack of auto-brightness as one of the downsides to this device.

It does have Auto Brightness as if you put a finger over the light sensor the phone screens dim.
The phone had an update pending the day I purchased it so most of the reviews I have seen are out of date. This phone is excellent at playing games.

I hear that. In love with my Xperia Play.
Guys can someone tell me. A lot of reviews say that the screen is very dim even on max setting and a lot of reviews say the exact opposite. So what is it?
Mine is perfect in the sun. I'm starting to think there are 2 types of screens involved, anyway to check what screen you have without opening the device up?
Screen brightness is ok for me, but just remarked the display have some ghosting issues. Slide beetween programs screens and observe carrefully the icons.... with red "Adresse" one this is very visible. i can't belive sony use a high response time display on a gamer device.
so yeah. title says it all. its sad how small things can f**k up an awesome phone.
that doesnt mean i wont buy it forever though. but those things are really annoying.
first :
my screen. was yellow. it has a yellowish tint . the whites looked yellow. while my iphone is totally cool blue white.
and i am very OCD about this. god knows how many galaxy S and iphones i returned because of this issue.
and the store didnt have any stock back so there was no option but return it or keep it.
second :
i knew about this issue but god i didnt know its that annoying. no option to turn off the auto brightness. its very low for me . i have to keep a light close to it to keep it on high brightness. i dont care about battery i want to enjoy my gaming sessions with a screen i can SEE ffs.
Third :
i was playing the N64 emulator. mario 64 sometimes lagged at the beginning of the stage, but once you play, its ok. F zero was running below 60fps for sure because my brother has a nexus S and it was super smooth. killer instect not playable on both phones. Xtreme G not playable on both phones.
maybe too many things were open thats why it lagged a little in my gaming tests.
i love the hardware design. and i am sure the roms will fix the auto brightness issue. all i need is a phone with no dead pixels and with a screen that doesnt look like someone pissed on it.

press the brightness button up to 3 times each time you press it the screen gets brighter until it hits 100% and then goes dark again if you press it one more time.

As mentioned this doesn't turn off auto brightness.
All it does is make your brightness 100%. If you cover up the auto brightness sensor, your screen will dim.
I don't own this phone but I do own an HTC EVO and there is an option to turn off the auto brightness. To do this you go to Settings > Display > Brightness and un-check the "Automatic Brightness" box. After that just move the slider to the highest setting and you should be good to go.

I'm positive that a function exists to turn off auto brightness on the xperia play, but at present Sony have omitted any functionality of accessing this from the end user UI.
Meaning it is not possible to turn off auto brightness unless you start rooting and customising your own ROM.
Use "notification toggle" from the market you can disable auto brightness.. But tbh its pretty well implemented..
As for yellow, I have the same issue, but I look at a galaxy s and its really blue, look at my wifes n1 its got a red tint.. The warmth of the screen colors will be adjustable once the phone is rooted

did you try the program your self on your xperia play and it worked ? because if so. thats a fix for the problem everyone is complaining about and it deserve a new thread to be made by yours.
as for the yellow. i am not sure if it can be fixed or not. on nexus S they fixed it. the voodoo developers made it work. but i highly doubt he will work on xperia play as he didnt show an intrest aside from galaxy S and nexus S

For everyone still having problems with Auto Dim on the Xperia Play, there is an app in the Android market made just for the Xperia Play!
Search: Disable Auto Brightness by hatcyl in the android market!
This app will stop the screen from Dimming / Brightening once it is being used.
Alright guys ...
I had created an application to disable the auto brightness feature of the Xperia Play. The app has now been updated ... and it's great!
1. Thanks everyone for the support!
2. The app has been updated.
New features:
a. Toggle Auto Brightness from launcher.
b. Tasker support (Kinda)
c. THE SCREEN IS NOW SUPER BRIGHT!
Thanks Everyone!
Get the app: https://market.android.com/details?id=com.hatcyl.android.Disable_Auto_Brightness
ps. This app may also work for other Sony Ericsson devices!
I having similar issue.
Got a new Xperia Neo V and the screen has a yellow tint. Googled around & found that I am not alone. Brightness etc is fine but color is not.
Now since I am still digging in I wanted to know if its a known problem?
If so is there a fix?
Hardware or software?
Thanks
Good job for bumping a dead thread!
If you have a yellow tint to your phone, you have two options. One, you can search for an app of some sort that can adjust the system colors on your phone.
Second option, you can take your phone back and complain about it, if it's been recent enough that you purchased it, you should get an exchange.
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.

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
Seriously after reading TS long posts still*cannot figure out his problem
please post shots to show your issues
I have been using CM9 roms since build 2 and do not seem to notice such issues or maybe i am blind ?

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.

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.

Same. I don't often stare at my phone from a distance of 3cm to see any imperfections.

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.

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.
http://forum.xda-developers.com/showthread.php?t=1800117
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?

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.
