Xperia's color gradients smoother than on other devices

There are always complaints on this forum about color banding on the Xperia's 65k display, so I thought that on my new Galaxy Tablet which boasts '16 million' colors in its specs this issue would not be present.
To my surprise, Xperia's color gradients are a lot smoother.
One example would be the XDA app welcome screen which is very smooth on the Xperia's screen, but shows coarse banding on the Galaxy Tab.
The dithering technique on the Xperia seems a lot more sophisticated and I came to question if Android OS is even capable of displaying over 65536 colors at all.
Any insights into the issue?

SE changed it to look better becouse normally it would should look worser with 65k and they didnt implented 16m Colors so they changed this to look better.

Samsung always fudge their numbers.
I remember buying a samsung monitor, which was the most expensive at the time, advertised as 16+ million colours and the thing done some horrible dithering - Everything had dithering on it! EVERYTHING.
The older LCD 16bit monitor it replaced had no noticeable dithering at all and gradient changes were subtle.
I've never bought a Samsuck product again.
The samsung galaxy S is also doing some weird stuff with its colours, it's blacks are fantastic but everything else is bleh!! and the pixels are about 10X bigger than the X10s.

The color from 1.6 were noticeably garbage....alot of my favorite wallpapers looked like **** with lines all over....I couldn't even use them. Then SE announced they would not be giving us 16M colors in 2.1 so I was pissed! BUT! I didn't know they were going to do something with the colors...because whatever they did they most certainly did a damn good job because the colors in 2.1 are phenominal! ALL the wallpapers I choose look AWESOME! As for Samsung....I think there super amoled screen is overated...I just sold my Galaxy S to return to the X10...the screen is really nice on the Galaxy, but like I said before the higher resolution on the X10 makes it a very VERY close match IMO.

a bit off topic....can you post a pic of your X10 next to the galaxy tab.Want to see the size comparison

Yes....dark blacks aside, the colors in the SGS are too oversaturated and a pain on the eye. Also, all the AMOLED screens have a strange greenish-blue tint to the colours - I have nticed this in all AMOLEDs, right from the Nokia N86 to the Samsung Wave to the SGS...

DSLR Photo Illustration of visible screen burn + ink marks issue

Hey xda members,
just had a bit of spare time so I decided to make some photos of my GS2 while displaying a totally black screen.
Normally you can only see these "effects" when you're in a completely dark room while looking at the GS2 being the only light-emitting source through its display.
Note: The actual purpose of this thread is to educate those people who can't imagine what burn-in/ink marks look like in reality. That's it, just plain visual information.
So I hope this isn't an issue even if there may already be a similar thread
I made some of the photos with the roomlights turned off and others with a very dim light.
The photos were shot using a Nikon D3100 DSLR with long exposure/high aperture settings.

As you can see in the first photo (below), even if the GS2's display shows a completely black image, which should result in a black display (OLED = pixel off) it shows weird marks and still emits a tiny amount of light.
In the second photo I have marked all the relevant weird spots (including screen burn-in caused by grey status bar [see below, marked by arrow])
The OLEDs in the burn-in area seemed to wear out faster because of the static grey shade it was displaying all the time thus resulting in this permanent color change in the affected area.
This burn-in was apparently caused by this theme which I was using for several months. As you can see, even the status bar in a dark grey shade can cause burn in.
A couple of more photos (with different white balance):
See below for photos in full resolution:
Hope this helps in any way and gives those people an impression who can't really imagine how screen burn-in can be caused and how these display issues (ink marks) actually look like when you capture them properly.

Very interesting indeed. Thanks for the great images, it's certainly an eye-opener to one of the main drawbacks of S-AMOLED screens.
Regards.

Roughly about nine months, bought it in October 2011.

Hope this is no news? Every AMOLED burns in (like crazy). Been doing that since the first models were on the market.
Every SGS2 has it, whether people say yes or no. On my SGS2 it was clearly visible after around six months. Knew it beforehand so it was no biggie/surprise.

Yeah, also knew it before buying but I never thought the burn-in would look like that so I thought I'd share my experience with the world
While it does look pretty bad on the photos, you can't really see these issues when the screen is turned on with decent brightness, so it's no issue for every day use, but it would be interesting to know how the burn-in looks like if you use your phone for example 3 years.
Still, it looks already really horrible after 9 months of use when you look at the photos. I hope the OLED-technology makes a giant leap forward in the next years so one day these display issues will be a thing of the past.

thanks for the images, i find it disgusting to have that burnt in on a topline expensive phone in short time.
this is my first amoled phone so i dont know what to expect after a year or so, its bad for those who keep thier phones long term, would like to see how the screen is in 5 years time
is it bad when you watch a movie?

Well, it depends while watching a movie. Sometimes I can see the burn-in in movies with a lot of dark scenes, in other movies this issue is not apparent.
Either way..since I discovered this issue, I cannot ignore it anymore which doesn't mean it annoys the hell out of me but still it's a pity to see the phone 'degrading' already after not even a year and spending a lot of money on it.

S2 screen better than S3

I have to say that side by side the S2 screen looks more vivid, brighter, and text is clearer.
My son came over with his new unlocked S3 and I have been playing with it to see if I want the upgrade. The screen looks pinkish on a white backround compared to the S2. Also the brightness seems not as strong as the S2.
Am I missing something, dissappointing to say the least.

Well other than the pink tint, poor view angles, pentile matrix and gross over sharpening artifacts, the galaxy s3 display is much superior. It has much better resolution. But I agree with you text looks poor in default mode.

Your son must have got a defective unit.Refer below for the pink tint issue:-
http://forum.xda-developers.com/showthread.php?t=1658601
And as far the screen comparision goes,heres the another link bellow:-
http://mobile-review.com/review/samsung-galaxy-s3-fl-en.shtml
On the above review one can clearly see that the s3 is superior to s2 in terms of sharpness and as far as the vividness goes they are nearly the same but the brightness on s3 is lower than s2.

Not really. I did a comparison with my friend S2 a few days ago. S3 screen beats S2 hands down. S3 is brighter, colours are more vivid, sharper and viewing angle is better too.

My S2 screen was very good but nothing like the S3. Big big difference. S3 blows it away.
Sent from my GT-I9300 using xda premium

Checked my S3 against the S2 of a colleague... S2 cannot even be compared, it's just soooo blown out of the water. OK, S3 is pentile, but really it's got a wonderful screen.

I compared my new sgs-III (i9300) with the sgs-II of my girlfriend and in my eyes the screen of the SGS-III is much better in every single aspect.

I loved my GS2 a lot because in many ways it was just so ahead of its time but the HD screens look better, especially on full brightness in the store displays. I looked at the Note, GS2 HD, Gnex, GS3 and they were all better than the GS2 screen.
But yeah, back to my point. I believe GS2 might have triggered the nostalgia factor in many because it was just so damn good. Similar to how Die Hard 3 sucked compared to the first two and Soul Calibur one was the best game ever while the sequels were jokes. It is all about first impressions so large that the sequels can't possibly meet.
Technically though, in my eyes, the HD screens look a lot better. Defintely not as wow as when I first saw the GS2 with a bright live wallpaper though.

As my exp, overall, S3 display better S2 display . S2 display got many problem and not uniform. S3 display are uniform and HD display look like much better than WVGA, down the disadvantage of Pentile panel.

Were you missing your glasses? Serious question, maybe you didn't have them on.

What a strange thread. I used to think my SGS2 had an amazing screen, and I guess it did. But after using my SGS3 for a few weeks the SGS2 now looks incredibly grainy in comparison. Sure there's some tint to the SGS3 but overall it's a huge upgrade.

Then it must be the screen protector he has on it? Is one of those invisible shield ones that does not have a smooth apperance but sort of a very light orange peel.....
Can that be it?

Saying the S2 display is better than the S3 is like saying "My 15 year old tube TV looks better than my 720P LED TV"
wel all know the S3 does take colors and put them way over the head but it does look more sharper and richer than any other device before it

how is the screen under direct sunlight?
thanks

I would say that this is the issue.

It's probably not the screen protector. As mentioned before, many S3s have defective screens with tint issues. The extent of the discoloration varies from unit to unit, so your son might have been unlucky and gotten a very bad one.
Samsung knows of this issue so you can get an exchange.

He will never work with it.

Actually almost all S3 I tested in stores has a pink tint to the whites. A few of them are more yellowish than others but I can safely say none of them has perfect white.

Colors are washed on Nexus 4

Just received my Nexus 4 today and the color are definitely washed (not so popping) on the phone. I actually think they are sub-standard than other lcd screens. Anyone agree? Can a custom rom saturate the colors more? Is there a way to saturate the colors without a custom rom?

I don't agree. I think the colors look great. Color reproduction is just more accurate. AMOLED colors pop because colors are oversaturated. It's unrealistic and I prefer the colors on an IPS display. In any case, you'll probably get used to it shortly.

pictures so that we can compare with other people who have the phone

The colors on my device are not washed out what so ever. They seem to be pretty accurate, but not eye popping like amoled. If i try to view the phone at an angle, there is a yellow hue but that's it. Very happy with the screen

Well the Xperia S has just a LED-backlit LCD screen, not even IPS. I never liked AMOLED in any way.
Sony does have something that is superior to Korean companies.

The screen looks fine to me on my Nexus, although I find the one X's screen a tad bit better. No biggie tho

I won't call washed out but colors on my Xperia TL look better. I checked videos and lot of pictures from smugmug and flickr. While I liked colors on Xperia better I thought Nexus displayed more accurate colors.

Judging by the chrome icon. Thats how green red yellow suppose to look like. The dynamic and standard option on the galaxy s3 make the colors over saturated. So naturally. Your eyes are use to seeing stronger colors. But thats not how they are like in real life.

OP is used to amoled. This panel is absolutely gorgeous.

I have a Dell Ultrasharp for work and use the same wallpaper from Jellybean, the colors are definitely undersaturated on the phone.
Realistic colors mean wide color gamut, which means being able to do both unsaturated and saturated. The phone cannot do saturated colors well, which means it has a narrow color gamut and only looks realistic when its not showing an image with high saturation in it.

Wait for these kernel devs cook something up like on the GNEX, edit the contrast and things will be popping!

Yeah I'm used too amoled also and noticed the difference, the colors seem very similar to the Nexus 7 which makes me wonder if it's a color profile or something that can be IMPROVED (ie not 'fixed') with software updates, mods and kernels.
After a few days though, I definitely noticed the difference in terms of usability.. this phone is much nicer to use than the S3 was, and I'm not automatically rushing to the night mode settings whenever possible.

Does the screen have a bluish tint in the whites similar to galaxy s3?

have they improved it? I can't find any close picture comparisons.. Thanks.

Looks better, but still there. I guess they're doing it to increase screen life or something, but absolutely hate that.
Once I installed Perseus on my Note II, I could hardly believe I'm looking at the same screen. Looks even better than iPhone 5 after calibration

yeah, but note 2 doesn't have pentile, doesn't it have a superior screen?

It does, yeah. But you can still see the bluish tint there. SIII/IV it's more greenish isn't it?
I have no idea why Samsung doesn't use RGB instead, is it because it isn't yet available for high PPI full HD screens?

I believe posters on here claimed cost reasons. too bad.. I prefer the overall design and build, screensize to handset ratio of the s4, but like the htc one screen..

That might not be apparent in normal vision though. S3 has noticeable graininess, but the pixel density on S4 should pretty much settle that IMO.
And I don't know if they took the screenshot with adobe RGB mode or saturated standard mode.
I love SAMOLED, but just wish if they could switch entirely to RGB. Wouldn't mind paying a few extra bucks either tbh if they implemented that on Note 3.

I don't think they can manufacture FHD 1080p yet. At least not in the amounts that the GS4 would demand at a reasonable price.

Yup, two issues: sharpness and color. It looks like the higher resolution overcame the less sharp drawback of pentile, but color tint looks is still there. need to verify what color mode the phone was in though.

welll, just got back from store. htc one's have multiple dipslay with different WB. but the s4 definitely had better WB in my eyes.

Why is this thread even open ? Amoleds will always have a bluish tint. LCDs always have better whites but suffer on black levels.
