Screen banding - Galaxy S II General

First off, amazing phone. So amazingly fast and thin, makes my desire feel like a toy.
I have noticed some banding on the screen, mostly on greys, was just wondering if others have noticed this too. Gets a lot worse if lcd density is changed as well.
A wallpaper cropped exactly to size, and tested on my desire, its banding too.

Can't post links yet, but since this screenshot taken by pressing home and power shows the banding as well I'm wondering is this a software fault?
Our is this going to be bad graphics on a fair few apps?
Thanks in advance
EDIT: just noticed on my computer the screenshot looks perfectly fine, but on both my desire and gs2 and a friends hd2 it looks banded.

Dot matrix on screen

Can anyone see a matrix of dots on the screen when it's turned off? It may be more visible under direct light.
Thats normal for many cellphone screens, don't sweat it.
Yes, I just think that's the way the screen is

Thanks guys. It's just because I could hardly see them on my previous Desire, while they are a bit more pronounced on the DHD.
Only on 4.3 screrns from htc hd2. Dhd. Evo all have them

Its a regular LCD screen, rather than AMOLED/SLCD etc, which are less prone to matrices being seen in certain lighting conditions.
the dots are visible on my girlfriend's legend.
they not visible on my magic.
next time i see her father's desire i'll have to look at it a bit closer to see if it has them.
In the right light/angle you can see it on many phones, my Galaxy S is the only one where I have yet to see it at all.

Display colors are not vibrant

I have installed SBF 1.5.2 right after I got my Atrix so I don't know if it is related to that but in my opinion the colors of the display are not vibrant / colorful compared to my HTC Desire Z (Vision/G2) and that phone has no AMOLED.
Compared to the HTC the colors all look a little bit greyer and I don't like it.
Is it possible to change that or am I the only one?
Thanks in advance.
You're comparing two different screen types. The Atrix uses TFT pentile and the Desire Z uses S-LCD. The Atrix is already known for some washed out colors like yellow.
Ah, thanks.
So it is not possible to change that with a software update like Google did in Android 2.3.3!?
I agree that the display is "not as nice" as other phones. My captivate IMO looks better.
yes the captivate is brighter but it also hurts my eyes after staring at it for a while. i wonder if there is going to be a program like galaxy tuner for the atrix. with galaxy tuner you can adjust the yellow color of the screen.

It could be possible, we just need to tear down the kernel (once it gets worked around) and play with it some. It was kinda funny though because after giving my Captivate to my GF and getting my atrix, I look at the Cappy and go "Holy crap that screen is REALLY blue"
I was surprised on the Atrix screen. The forum didn't give it justice. The characters looks very sharp. Colors are easy to the eyes and no pixels at all!

just take a look at your battery meter when it's green.
any green (like real green, not dark) text on the web shows the obvious differences between the PenTile display and a regular LCD.
IMHO the display of the Atrix is one of the worst displays in a high end phone that I have seen in the last time.
Only the resolution is great, the rest isn't really high end.
Yellow looks more like dirt and faster scrolling or movements show black shadows (e. g. in Angry Birds).

Display has a pink tint!!

Please help! I just bought the Bell galaxy s 2 today and realised that in low brightness settings screen has a pink tint.
Does anyone have this issue? Its more visible in grey colors. When i compare with my galaxy s, galaxy s' whites are true white and galaxy s 2's white are pinkish tint on it. When the brihhtness is at %100 its not that visible but once u set it %0 it becomes pinkish.
Is it what it suppose to be or its defective?
Note: yes i played with background effect but it didnt help. I am running KG2.
Edit: I compared with galaxy s again and if I make the brightness %100 on galaxy s 2 both screens almost identical (although SGS2 still has little warm whites) but at %0 brightness when I pull down the notification screen sgs2 has literally pink hue
Why not anyone comment on this? 100 something views and no comments?
U guys all have sgs2. pls at least share your phone's display colors so I can know if something is wrong with mine.
Yep got it to and also pink on camera also mine going back to Amazon tomorrow had two in a week with same problem Ive got one ordered from another retailer ... but I think its a inherent fault

Yup..got it too..in Indian sgs2..got screen replaced bt no difference..for me most visible when browsing xda app for long..also pink in camera..tried everythng bt can't get rid of it..its company fault..

Are you saying your whole screen looks rather pinkish ? I've seen couple of devices that were pretty much reddish when showing white, but i think that's not normal. You should replace it.

Yes whole screen has a reddish tint. Especially grey colors. Instead of grey it displays reddish. If i compare Gmail app with Sgs side by side, my screen has ridiculously pink color.
I wonder if its a software issue or hardware? Cuz I remember in sgs hardcore's kernel he made an.option to change the colors.
This is my second sgs2. First one had a dead pixel. So I didnt wanna go right away and change it. I wanted to ask yours.
More input will appreciated.
I uploaded a pic SGS and SGS2 side by side displaying Grey Graident Colors. what do you think?
If your phone looks like the one on the right, get it replaced. No rom/firmware will make it look good.

I'd take the lack or response to mean that it's not a problem experienced by many people. If your read the threads talking about the display, you'll see there's wide variations in color temperature. Cool/blue seems to be normal while there are reports of phones leaning toward warm/yellow. Pink hasn't been reported a lot so I'd exchange the phone.

I am also from India and I dont have any such problem with my sgs2...
My girlfriend and I have the same german sgs2 (dbt) and mine has a bit of a greenish tint whereas hers had a but if a reddish tint. You can't notice it when using the phones alone but when you put them side by side you can notice it a little bit, but really not that much. Seems to be an AMOLED thing. Maybe I'll manage to take a photo for you.

Thanks a lot for that image. I have been wondering what people were talking about when they mentioned pinkish screen...
Luckily I don't seem to have that problem. It seems like there are a few defective screens out there.
perhaps supercurio will have a voodoo colour fix with the sgs2 whenever he releases it. It fixed the tinge on the original sgs. Look it up if u are unfamiliar with it
I changed the phone today and got a new one. Its better now and significany less pink color.
Also I discovered something that the pink tint is only visible when u look at the screen 90 degrees. If u tilt the phone a little (5-10 degrees) to left-right or up-down and view like that the color turns normal (like my year old sgs).
It made me realise that this is a screen coating issue (maybe coating causes polarisation). So do u think this will go away with the time of use?
When I turn off the screen and check it under light by tilting I can see a little purple glare.
What do u think?

Nexus 4 annoying visible IPS sensors

Hey guys,
I've had my nexus 4 for a week now and I am super pleased by it. The phone runs like a dream.
The only issue I seem to be having is that I can see the IPS sensors even with the screen on!.
I'm talking about the little transparent-gray squares all over it, not about the super awesome dots that you can see with direct sunlight.
This is flipping me out!
Is anybody else having this problem with it?
I can't appreciate the beautiful screen because of this.
Also, when displaying single color frames specially dark ones, like on the clock app , the colors are not really solid.
I get this vertical stripes that are approximate to the color but not quite it.
Im posting a screenshot but I don't think that youll be able to notice it since it may be a hardware problem.
Sent from my Nexus 4 using xda app-developers app
That's a hardware thing, not visible in screenshots. You'd need to take an actual picture.
Are you referring to the dot grid that is visible in direct sunlight? Everyone has is. It's because of the fact that the screen is integrated into the glass.
I think it looks kind of cool but that might just be me.
Edit: Gotta read the whole thread first I guess you're not talking about the dots. I have no idea what you're talking about then.

Question to the OP. Do YOU see anything wrong with those images, or is it a hardware problem? I can't see any difference between your screen shots and my phone.
Damn it man, now i see them too -.-
I went to the clock app, and i can see some stripes on the left but mine are vertical.

Haha Dude that's the digitizer. Don't worry. It's all cool.
Chill out people.. Its just the digitizer that you can see, so close to the screen for better touchscreen responsiveness. The most likely reason you can still see it with your device screen on is that you have your brightness too low.. Put it up
even amoled screen are also the same

When I first got my Nexus4 the weird screen was the first thing that popped out at me. Between the visible digitizer matrix that glints when it catches the sun wrong, to the odd rectangles that can be seen behind the screen I was initially bummed and thought about returning the phone. It doesn't even bother me anymore
This is my 8th android device and the first one that has a funky screen like this, but it really isnt a big deal. Under 95 percent of conditions it looks really nice
I have been able to see the digitizer on every single capacitive screen i have ever owned.
@David_Azar I have to agree.. initially I was disgusted by how prominent the digitzer pattern was, I've never had ANY screen show it as much as the Nexus 4 does.
However, the vertical stripes you're referencing is commonly referred to as "banding". I have this on my Nexus 4 as well, most visible on grays (especially darker grays).
I have been doing some research and I believe the banding issue will reduce over time. If you check your screen when displaying a white background at max brightness, such as gmail or chrome browser, you should see a slight yellowing of the whites. It appears this can be due to the adhesive they used to glue the digitizer to the screen not curing completely. After several weeks of use, the heat from the processor will help cure the adhesive causing the yellow to disappear after a while.
I cannot say for certain that it will completely resolve the banding issue, but I have noticed that the worst banding is in the areas where the yellow tint is most prominent. I have also been testing my display every day to monitor any changes, and I am happy to report I do see a minor reduction in both the yellowing and banding (I've only had my Nexus 4 for five days so far).
Give it a couple of weeks, run some intensive games to get the processor to heat up every day. Keep brightness at max for the next few weeks and let us know if you see any improvements.
As for the pattern of the digitizer in the glass.. it's not going anywhere so get used to it. I don't like it much either but it seems to be less prominent once you start becoming used to it.
Good luck, let us know how it goes
Hey man,
Curiously enough I've never had the yellow tints everybody's complaining about. I'm used to The digitizer matrix ( rectangles) buy at first it was really weird. I was coming from a non HD display ( a RAZR Maxx) so naturally, I expected that my N4 would have a perfect screen.
I've had my N4 for almost two months now and the banding has not reduced. I made some research over the last month and I found that with some kernel settings for saturation the banding is reduced. I'm not sure if it is really reduced or the clear gray tones that have the banding just don't appear anymore because of the saturation.
The Trinity kernel reduces this a bit but like I said, your screen will look life a f*** ing AMOLED.
Right now I'm using the kernel provided by the 123 FAUX CLOCK project. I'm using the LG factory presets and for the most part I'm really happy with the screen. If you or anybody else comes up with a different solution, let others know on this thread.
Peace brothers.

Just for kicks, if you stop by a T-mobile location compare your screen with the display model and see if you can spot the yellow tint on either screen (on a white background)
I will update this thread with my phone's progress (or lack thereof if it stops improving).
I get banding issues also, more noticeable in grey backgrounds; but I can I see them in other colors if I look hard enough
I use a dark black theme to avoid looking at those bands
I can say this. I've had a ton of devices..latest was s3 and I'll just say I'm stoked to have IPS over pen tile. Just knowing HD was plagued by this alone was enough for me to ditch Sammy all together especially after seeing rgb on note 2 was no better. This is my opinion of Samsung's design ...I know why they chose it but I can't and won't buy another amoled until they get another tech in order. So now I say kudos on IPS but I'm surely a screen purest and I found these hardware screen/digitizer artifacts you speak of and to me its so much less noticeable. Your not alone. You just like good clean HD like me. Lol HTC one should be a nice one to check out...
Sent from my Nexus 4 using xda premium
That would be a little like kicking myself in the nuts. Nothing good can come out of that.
If I spot the yellow tints once, then I will always look for it. I hate doing that with the banding but it's an automatic thing.
I dunno why but it really bums me out whenever I have a problem with my phone.
Let's keep posting of someone finds a solution or something .

I've got the quite visible digitizer rectangles too. In anything less than a dark room if the phone is not on a perfect angle they are visible.
I can't really tell if "everyone's" is like that, or just some are "worse" than others.

Here's an image with them visible with the screen on (and at an angle) - difficult to take a photo of - but much easier to see with the naked eye.

Went and checked out an Optimus G today (Nexus 4 isn't actually released in Japan). Given that a Nexus 4 is just a remodeled Optimus G I thought it'd be worth comparing screens. The digitizer matrix is barely visible on the G I was looking at with the screen OFF. With it on you could almost see it at some angles. It is much more visible on my Nexus 4 which you can almost always see with the screen off and at an angle and often with the screen on.
I'm leaning towards my phone being "less than a perfect example of a Nexus 4" and not the "norm" at the moment.
they are much more noticeable in Rev 11 devices and they where barely visible in Rev 10, i am sure that there is a technical reason behind it

See that explains it a little more. Not sure I see the logic in putting a screen with pretty decent viewing angles on a device and then sticking a really visible digitizer on it though.
I've contacted the seller and I guess I'll wait and see what they say in regard to it.

Huge screen issue with i9505

I bought an i9505 today. I noticed very bad scrolling artifacts especially on a black background. This can be best seen when scrolling up and down in a menue in the preferences. The white letters on black background smear alot. This effect gets worse when turning brightness down. The responsiveness of the s4 display seem quite bad. The s3, which i also own does a whole lot better in this regard.
Can other S4 owners confirm this problem? Has the octa the same problem? Main reason i bought this phone was the oled display. I am quite dissapointed.

something is definitely wrong with it. exchange it immediately in case something is wrong with the second one.
Mine does it too. Most noticeable scrolling through contacts.

So if I am not the only one experiencing this it seems to be an inherent problem of the new amoled. In theory amoled has a very fast response time. Maybe it has to do with the fact that the s4 displays true black i.e. the screen is absolutely black in black areas of the screen. The s3 does not turn the pixels completely off, it has blacker blacks than lcd but no absolute blacks like the s4. I am sure Samsung did this for a reason in th s3, maybe to avoid the problem we are experiencing with the s4. I wonder why none of the reviews reports about this issue.

Mine doesn't smear when scrolling unless you mean if you scroll fast it looks smeared? I put that down to scrolling quicker than my eyes can focus if yours is smearing when moving slowly then I'd swap it!
Sent from my GT-I9505 using XDA Premium HD app
The effect can be best seen on black background with brightness set to low. For example when scrolling in preferences watch the horizontal grey sepparation lines. When scrolling slowly the almost dissapear on my phone. So maybe one should not call it smearing but there clearly visible moving arifacts on my phone.

I have the same problem. It is annoying in black backgrounds whith grey letters.
I noticed this straight away and started a thread here http://forum.xda-developers.com/showthread.php?t=2252445 (5 pages long already)
My S3 does not suffer with this problem at all.
The screen is a step down apart from the blacks which are much deeper.
My issue: the red subpixels stay on, this is the SGS4 and SGS2 viewing the same 100% black image.
The effect is a bit more dramatic on these pics than real life, to get a proper exposure. The red pixels are only at low intensity, but it's still easily noticeable.
Hi.
I had the same problem with I9505OXAAMDE firmware. I update firmware to I9505OXAAMDM and subpixels are ok. Now my screen is black, but now i have smearing in setup menu and contact.
I hope that in the future fix this problem.

Interesting. You did not have the 'smearing' before? Because I do see some of that also. On i9505-XXUAMDF.
In the previous firmware did not have smearing.
