Lately I've noticed that my Milestone has some problems with displaying colors.
I have attached the screenshot of my home, where you can see terrible transitions between similar hues.
lso, there is wallpaper file attached, which seems to be okay to me.
Is it common with those screens or it's just my Milestone?
my milestone does the same :/ could it be that it does not have 16 million colors?
24 bit images on a 16 bit display will cause the banding you see.

i find it weird that no reviews mentions this or even the specifications sheet, :/ the desire has an 24 bit display?
That's what I thought, pretty much.
Still, it being not mentioned is strange, as it seems to be fairly serious issue. Unless it's possible to convert images with no quality loss visible on the screen.
The proper term is dither, in cyanogen you can enable surface dithering in cyanogen mod settings > performance which should improve image quality at the cost of performance. Not sure about other roms.

im curious to know about the display used in the droid 2 and droid x, the htc desire, are they using a 24 bit display now?
The Droid/Milestone does have a 24-bit display: http://www.displaymate.com/Motorola_Droid_ShootOut.htm
In fact, the Droid 2 uses the same LCD.
That gradient problem with your image is probably caused by several problems:
1. The picture is not a true 24-bit image.
2. Google's Gallery is limited to 16-bit!
The Milestone/Droid has one of the finest LCDs on the market, and if it had not been so expensive when it was first released in Canada ($600!), I would have bought it in a heartbeat, despite the locked bootloader.
EDIT: I've just examined the photo on my 24-bit Aquos, and it looks perfectly smooth, so the problem is being caused by Android 2.1. FroYo's Gallery is also limited to 16-bit.
So what gallery could I use to put wallpapers on?
Flikie does pretty much the same, as it uses Froyo gallery.
Well, it seems that application named Wallpaper Set and Save (find it in market, it's free) is the easy way out.
This app lets you set the 24-bit wallpaper keeping the desired quality, more or less.
Though, it may make Launcher Pro FC a couple of times right after setting the new wallpaper, then it works flawlessly.

if the 16 bit problem is androids fault how could google not fix this in 2.2? so thats why a lot of of phones use a different gallery than the stock, im surprised this isnt mentioned more often

Yeah, I agree. Apparently, Samsung's Galaxy S Gallery is a bit better. Not truly 24-bit, but the Galaxy S adds improved dithering. The Galaxy S, with all of the hype about SAMOLED, is not even a real 24-bit display You Milestone/Droid/Droid 2 folks have the best Android screen, IMO.

True.
Google is not eager to tell you the answer if you don't exactly know what you are looking for. And for non-technical people it may be hard to guess.

i dont know what the droid screen was like but i got a milestone 2(droid 2) yesterday and the screen looks awful on it, nothing but dull colours, i just made a post about it here
http://forum.xda-developers.com/showthread.php?p=10401973#post10401973
Seriously can't work this one out, do I get my screen changed or not?
Should I wait to see if ICS makes it any better?
This phone is perfect for me except this issue with the blacks / greys. Even when i zoom in on dark parts of pictures taken with the phones camera it turns into a pixelated mess, so this is defiantly not a low quality source issue, its hardware or software related, but which?
Advice please guys. Many thanks!
I know! Right?
The screen Is freaking awesome, simply the best on any smartphone, but why those blacks haven't been fixed yet???

I really am at a loss to what you guys are complaining about. I'm either not that fussy, or deluded to the fact that what I think I am seeing as 'bad' I pass off as something else.
From what I've read around the forums, what should be a shaded series of greys/blacks in an area are appearing as blocks of black/darkgrey instead of a gradual change.
I've always thought this was down to how videos/images where compressed or decompressed and displayed - which would almost certainly be software and not hardware?

Same here. My blacks look fine most of the time. When I do get grey blockiness I'm pretty sure it's due to poor compression in the video file, because other videos, large black areas look fine.
Can anyone give a link to a video available online in which this problem occurs (and the point in the video we should be looking at).
Maybe then we can get some objective testing with everyone using the same source file.
Maybe even have people doing screenshots to compare screens.
http://forum.xda-developers.com/showthread.php?t=1366014&page=4
I'm rarely using my phone in dark enough conditions to notice.
ICS should improve gradients, but won't fix the black crush if it is indeed a problem with the screen hardware.
I am probably going to regret this, as my Note was perfect except for this black crush issue, but I sent mine back to be replaced. And the issue was not just on videos for me so poor quality encodes are not the problem, I was getting it even with pictures taken with the phones camera. Said pictures taken with the Note displayed fine on my pc and my wifes Galaxy s 2, so it is deffo a problem with the device.
Please lets not turn this into another "who cares" or "its not that noticeable" debate like the other threads, all I am aiming at with this thread from now is to find out if there are any Notes in existence that do not have this issue!
Thanks.
I refuse to look for a problem that is not there.....
There is no phone or portable device in existence that is color accurate, either tonally or temperature or gamma correct out of the box, and to expect such is to be, well, expecting quite a bit too much.
Why do i make that statement?.. Well, given that a monitor or TV at ANY price are not accurately calibrated.
To get an accurately calibrated monitor requires a display worth using, then a color tone/temperature/gamma calibration system (which is ~$200 & up) and software that can use the resulting calibration profiles...
The SGN is a phone... tbh there is no "fault" or "problem" here, other than unrealistic customer expectations...
Would a settings app that could set globally set color temp & gamma be helpful? sure.. there is enough color temp variation in the spread of production tolerances in phone to make this useful... stop a ll the pink white /blue white issues
But will it make the SGN a color accurate display?.. no.
So... lets wave a magic wand and make it so... whats the point? the camera does not justify it, the movies you watch are overly compressed and not color accurate (never mind compression artifacts of banding, blocking and shading), youtube videos have no quality controls.. online TV, website videos and stills have major color saturation issues.. so what content will you access that is going to be useable on a color accurate display?..
well, 4 beers down and 2c more spent..

Dude, my pc plays / displays these movies and images fine with no artifacts, as does my tv, as does my partners Galaxy s 2, as does my Nexus s, so how can you say that there is no problem?
Anyway, I just had a look at my cousins Galaxy Note and that one is playing these movies fine, and is displaying the pictures taken with my Note without the chess board effect, so if you are happy to pay over £400 for a defective device thats up to you, but many of us expect to get what we paid for.

The problem is clear enough to see there, but it's not one I've ever noticed on my Note. I just tried playing this YouTube clip on my Note....
http://www.youtube.com/watch?v=syxd2n8S4AE
and could see nothing wrong with the video performance in a darkened (curtains drawn during daytime) room. I wonder how well this clip plays for other people on the Note.
I made a video of the Note playing this clip and I'm uploading it at the moment. It will take a while (81 minutes remaining at the moment) as I shot in 1080p. I'll post a link when it's ready.
FWIW I'm on the latest official ROM and my phone was sourced from Germany in early November. From my perspective there is no problem, which might make it quite hard for Samsung to fix.
My Note is running on ICS (CM9) and the color rendering is substantially improved over stock GB. Gradients are smoother and blacks are rendered cleaner.
My video is up.

I've played the same clip on my Note and it looks exactly like yours, no banding/crushing/clipping whatsoever.
I've tried a lot of Youtube clips and movie trailers but in only one of them I could see obvious artefacts during a fade out. I played the same clip on my pc and saw the same thing happen there so that's probably just lousy encoding.
Thanks for putting that video up, I hope my replacement looks like yours, its due tomorrow.
I got me new note, this one is set to uk language instead of german like the one I returned. It has the exact same issue, drops from 4 grey to 3 complete black and i am still getting the clipping, bloody Samsung, this was meant to be an upgrade from my nexus s, but most stuff looks better on that! Not gonna excahnge again, I will wait for ICS and see if Samsung actually acknowledge the issue.
@Mystic38. Whilst I agree with you that most consumer devices don't come calibrated to industry standards and that most consumer devices lack the essential settings found on the most basic of professional displays, I fail to see how any colour, contrast, hue, gamma or brightness calibration would affect the overall appearance, unless of course you are cranking the settings beyond anything useful and crushing the dynamics intentionally.
It's difficult to introduce visual banding or blocking in high BIT rate video or lightly compressed images by tweaking settings and calibration by a couple of percent alone, as there are near on 17 million colours. This leaves thousands of grey levels to play with and the human eye shouldn't notice banding or blocking with that many greys.
This presumably points to an issue with the way that video is presented to the screen driver or how the screen driver drives the screen. There's probably an issue with crushing where the hardware converts the digital signal to electronic levels of each AMOLED element. I have seen this problem on other devices, not just phones and most of the time it was rectified after a software upgrade.
Another thing to remember is that companies like Samsung are fully aware and accommodating of the fact that a lot of people now use these types of phones as monitors for photography and video production as I do. I use DSLR Controller and have no problem with crushing. Using the phone as a monitor has been extremely helpful and negated the expense of something which would have cost over 10 times the price.

I just got round to trying the ,png gamma test file on my Note. It fails the test. Everything below 4 is black and as you go through the numbers from 4 and above there are bands grouping four levels into one tone. Worse still, the tones alternate from greenish to purple instead of being shades of grey. Interestingly if I perform a screen capture the capture is a true reflection of what I see, which implies to me that the Note is actually sending bad values to the screen rather than a hardware problem, because surely the screen capture only cares about the data, not the physical appearance produced.
Looking at the same file on my laptop everything is presented correctly, so obviously the file is not the problem.
Yet despite failing this test I have never noticed a problem with the Note to cause me concern in normal every day use.

Have you viewed it in the gallery or in a browser? With my Note everything below 4 is crushed in the stock ICS browser but I can see everything in the gallery.

I think the gallery uses a different color gradient and temperature than the stock ICS browser, much as if you view a rich encoded black contrast video on the stock video player and on a custom app video player like MX player... you get varying results...
I think this issue is a mix of both a hardware and software one, and though the Official ICS upgrade "might" alleviate this problem, I surely believe also that since this is a combination of a hardware problem, the clippings are still there but perhaps not quite noticeable anymore....
I get that instagram is all about filters but I'm talking about photo resolution on the uploads. The photos shared from my One are far more pixelated and jaggy (overall crappy .jpgs themselves instead of filter related) than photos from my iPhone 4s were. Is there any reason for this drop in quality of pictures? What's the point of having this awesome camera if all the photos I share to both instagram and facebook look so crappy when shared?
These are 612x612 pictures there shouldn't even need to be any compression done on them to warrant the loss in quality.
Facebook is similar, I can readily zoom on my friends' iOS uploads from my phone but my uploads are letterboxed on my screen and I can't zoom in on them. It's frustrating when one of the reasons I switched to this phone was for photo quality.
I know it's not the phone's fault because they look great on here, so what's the deal with these apps and does anybody know how to fix?

They look okay but there's a noticeable drop in quality from the same scene (even the same photo if I put the iOS photo on my android phone). Either Instagram, Facebook, or the Android upload system is scaling the pics down more than is done with iOS photos.
It's not deal breaking but when part of the reason you switch phones is the improved camera tech on the new one, it's a little grating that your 2 year old phone's photos look clearer than your new one's photos on social media sites.

What's happening is that a 612 x 612 resolution photograph is being scaled up to a screen that is 1080 pixels across and more than an inch larger. The iPhone 4S only had 640 pixels across so its no comparison. The much higher resolution and the vastly larger screen is why the pictures look pixelated on the HTC One. Instagram should really consider increasing the image size to 1024 x 1024 seeing as how mobile displays have come a long way since the Retina displays of 2010.

I agree with what you're saying but actually my issues come from the photos themselves when viewed on a regular computer browser window. I can look at my instagram history from the photos I post now to the ones I posted a few weeks ago with my iPhone and they're noticeably jaggier for some reason coming from the One. It's a shame but hopefully it's a minor bump in the road towards the future I agree should happen.

I did notice that on the last picture I posted. The letters seemed jagged. Of course, we probably can't expect a fix for a while because all the major app developers cater to the iPhone users first. Instagram was iPhone only for a long time.
I think the 16:9 sensor may have something to do with it, as opposed to the 4:3 on most other phones

Ahh I gotcha. If anything it sounds like its a setting with the Instagram app for Android. If you can, maybe you can try it on another Android phone and see if the issues persist. If they do it's due to the app, if not then unfortunately it would be the phone acting wonky.

I think it may be phone specific. The pictures from my EVO LTE never looked like that. I will post the same picture from both phones sometime and compare to see if there is noticeable difference.

I went to the settings->advanced features and unchecked the two options there and my pictures seem to look better. I'm glad you've noticed this as well because I feel like people who've only used android don't realize how much nicer pics from the iPhone looked.
Yeah, I just noticed this as well. The pics actually look worse than those from my old Galaxy SII, which had a terrible camera. What the hell, instagram?
I've noticed this as well...the pictures take a big hit in IQ when uploaded to Instagram. The copies saved to the phone look fine, but they do look pretty bad on Instagram. Even the preview thumbnails took a hit.
My friend has a SGS4 and his pictures come out SUPER jagged....mine do not suffer from that problem but do look watered down.
Pictures look much, much, MUCH better on the iPhone 5.

It seems that the apps is over compressing and applying sharpening to them. I have the HTC One international version.
The last couple of days I thought I was going crazy when seeing the crappy quality of the uploaded photos.
I will upload a couple of pics later to see if disabling High quality processing in the Advanced options fixes this.
It most probably something related with new phones, as some Galaxy S4 users are reporting the same problem with their phones.

I've also noticed this. You are not going crazy.
OK, Just went to Best Buy to demo the gear VR. First - the demo time is limited to 3 minutes which made it a little difficult to get a good idea.
My major problem with the demo was the image quality. Now I was not expecting miracles. I have read the forums and expected sd effect but this was major sd. Large pixels were unfocused where one could see the red/green/blue. It was almost like an old crt that had been badly focused. I almost wondered if they had a bum unit.
I was watching the trailers in the movie theaters btw.
So Im wondering - is this basically the quality one should expect from the VR currently? Has anyone had experience loading their own films on the unit and is the quality better than the trailers loaded on the unit?
Any opinions would be appreciated (Again - Im wondering if the unit they had was just a bad one)
Thanks

Did you try adjusting the focus wheel?
Yes - the focus wheel had little to no effect. Almost as if it was there for show.
Possibly broken but remember it's only a QHD screen so there will be pixels visable. We need to wait for 8k screens... I love me gearvr and amazed our phones offer this ability
-= Note 4 & Gear VR =-
Sounds like a defective unit to me. Yes the picture isn't perfect but "unfocused and can see the red/green/blue "definitely not. I've watched gravity, avatar ,xmen and godzilla all in 3d on the vr and obviously it's not like watching in on a hd TV but you are watching it on a 100ft large screen in a virtual cinema which you can't do at home
Wondering - Has anyone loaded on hd rips of movies and watched them vs the trailers that they have pre-loaded?
Is the quality improved? Maybe their trailers are low bit rate. Thanks

Doesn't sound broke. I can always see the red/green/blue in pixels when focused. It always reminded me of CRT TVs.
I don't see the red/green/blue at all. Sounds like defected units. Also my pixals are extremely small. Maybe because I have 15/20 vision with my contacts in? I don't know.

I see them pretty clearly
They are visible if you focus your attention on them. Once you focus your mind on video or game they disappear.

I believe focus issues have a lot to do with the alignment of your eyes and the 3D effect. If you eyes are not aligned properly then the 3D effect may create a double image
Also I've noticed the eyepad with the nose bridge included positions the device on your face for better focus.
Another issue is just getting used to a slightly screen door image. Also remenber these movies et al are largely in FHD not QHD and that is also hurting the experience.
If your phone is rooted you can also increase the DPI which may help with pixel size.
Part of enjoying this is your brain just getting used to it. I find that focusing tightly on what I'm looking at as opposed to generally staring in a direction helps focus. Its not that focus with the unit is poor so much as the 3D tech is imperfectly tuned for each person. Also I think we've come to expect 3D things to jump out at us; however thus is not the effect 3D has in real life. In real life 3D merely adds depth and that is what this does more than in your face hollywood 3D.

hello community
I bought my tab s T805 a few days ago and yesterday watched "The Strain" on it.
Everytime when a black part (hair, clothes etc.) moves, there was a caudate behind.
Very annoying if there are more black objects and the camera moves...the whole picture looks unsharp.
Seems like it´s a comon problem of AMOLED Displays, because my Note 3 shows the same behaviour.
Anyone else noticed this problem?
Maybe it´s only the display of my tablet...
what app do you use for media playback and whats the source? own blu ray rip or purchased online etc?
I use Plex, Video is H264 rip of the blueray.
The Plex server streams the video to the tablet.

Yea, I've noticed this a lot. Doesn't matter if it's a game, movie, or static image. Any deep black spots will "smear" across the screen a bit.
Damn...beside this problem, the screen is really great!
Maybe I send it back and get an alternative...
As far as i know, only TabPro and Note 10.1 (2014) also have the same resolution.

I have seen similar in my Note 2.

Good article. I disagree with one thing, though I've never heard of OLED described as holy grail of motion blur. It's the holy grail of black as the pixels can shut off completely. But as for motion it is pretty much in same boat as modern LCD. LCD now has very fast pixel response too (not as fast as OLED), but because of sample and hold it has motion blur. Ditto OLED.
Even the $25,000 LG OLED uses sample and hold and has some motion blur. So yeah don't expect great motion in your $400 tablet.
I though Samsung had fixed the motion blur or at least improved it by not fully turning off the pixels so it take less time for them to respond, so it`s not jet black more like dark, dark, dark grey

Interesting side note. There will likely be a specific need for low persistence OLED displays for virtual reality applications in the future. This is an excerpt from the Oculus Rift website:
Low Persistence OLED Display
DK2 uses a low persistence OLED display to eliminate motion blur and judder, two of the biggest contributors to simulator sickness. Low persistence makes the scene appear visually stable, increasing the potential for presence.
Some facts about the OLED's used in the Oculus Rift:

Oculus' DK2 uses the Galaxy Note 3 AMOLED panel, overclocked for lower persistence:

I have been unable to see any motion blur on my T800, though i mostly watch animi, i do watch movies as well.

It's easily testable with a black image with some dark details on it like this one. If you even gently move it around in an image viewer many of the details will simply disappear.
Are any of you with this issue using power saving mode? I found that the slower refresh rate in powersaving mode does cause some screen issues.
