I don't know if any one knows this but I found something out interesting when I was trying to make a high quality Lock screen wallpaper.
I noted that even though I made the rez of the JPG I was using for the lock screen 480X800, and even though in the selector (the place where your re-size the orange thing to fit) the JPG looked full quality. but after picking the full screen and looking at the Wallpaper on the lock screen it was blurry and obviously re-sized... So I though maybe It's resizing because that black Into bar at the top so I made the JPG 480x790 but it still re-sized it and it looks blurry. Then I started looking closer at some wallpapers I used and sure enough there being resides and loosing quality from the original.
Any one know a reason for this? or do they know a way to stop this from happening? or is it just something that they made a mistake on in the OS?
The phone displays the JPG perfect and full rez any way or app I use to view it but when it's saved as a Lock screen wallpaper it looks like crap...
I'm using stock Bell UGKG2 firmware with the attached image for my lockscreen and it looks as good as it does in the gallery.
You can't tell with a photo like that. It dosen't have enough detail. Here I'll show you try this one I just made.
Try it and you will see.
P.S. How do you do the "Attach Thumbnail" thing on this forum?
Yeah, I see what you mean with that one. There's almost horizontal lines going through it when set as lock screen. My guess is it's the compression that it uses when it "crops" the image. I know you're not cropping it, but it's still doing something with it and that has to be causing it. I highly doubt there's a way around this....
You could be right it might be compressing it too. It just looked like Re-sizing. Wonder if i compress the photo in photoshop before I put it on the phone, to a smaller file size....
[UPDATE]: nope.... just tried it still makes it look bad...
@OP try numerous times and try your best to stretch it all, its retarded for a phone like this needing to render the image at so crappy quality, but eventually you will get it to work, after like 10 tries ive got mine looking as good as the gallery, just try ur best to put the orange box fully on the border of the screen, if you fail try more times untill you get it right.

Just tried a bunch and no-go. I even found you can turn the phone sideways and you can easily get it to the outer edged but it still distorts the image.
Setting the wallpaper in Samsung's way is plain stupid. I hope they change this method in future firmwares. I can never stretch it to fit the whole screen from the first try and it's a pain in the @ss to go back and try again every time you fail.

hello community,
does anyone beside me notice the screen going blurry while scrolling? best seen at websites with white background and dark letters. it really gives me headaches.
also noticeable while on websites is, that it's not only blurry but also graphics get pixelated everytime I scroll and resharp everytime when scrolling stops.
is this something special about the samoled+? bad refreshrate? maybe fixable? I'm using the phone rooted with normal ke2 firmware and kernel.
thx for your opinions.
I've gone through 4 (FOUR) Samsung Galaxy S2's with replacements due to various issues (overheating, restarting, corrupted screen) And on ALL of them, they blur with fast movement on the screen, especially noticeable, as you said, when it's dark text against a white background. This is purely becuause of the slow response time on the screen. It's a hardware issue, nothing you can do it about it.
Also graphics get pixellated when scrolling as the android OS lowers the quality of graphics while scrolling to make scrolling smoother.
These aren't really problems. Everyone is experiencing the same things as you and I. If anyone says otherwise it's purely because they can't notice it due to bad eyes or whatever but I assure you, it's perfectly normal.
thx for your quick response.
I feared that it's disappointing for such an expensive device. to me, it's kinda like looking at a bade configured screen or something like that.
so no weapon against a low response time, but graphics getting pixelated on a dual-core-monster ... i can go with that on weaker devices, but on this phone ... do you think it's worth asking if somebody knows how to disable that android "feature"?
and let me guess that other phone-screens (like LG optimus speed, which would be the nearest to an alternative) have that blurry problem too ... ?
thx again and feeling sorry for your 4 phones. but you still stick with samsung!
Noticed it too... However it is better here than on the incredible s I had for a couple of days.
With the graphical issue you mean the pictures getting bigger pixels when touching the screen huh?
Are you also having alot of these chess-like patterns while scrolling? Like on the iphone. Is this the browser that does it?
Yeah I was disappointed when I noticed the slow response time myself, especially considering this is a top end device.
I can't say if other comparable devices would have the slow response/blurry screen aswell as manufacturers always exaggerate the specs of screens to 'best case scenario' results, which is completely unrealistic. For example, Samsung states that the screen on the Galaxy S2 has a response time of 0.001ms, which if true, there would be absolutely no hint of blurring at all, however, as I said, they'd of measured it in a best case scenario, they were most likely giving the response time for GTG (or grey to grey, the time it takes for a pixel to turn from grey, to white then back to grey) and with the brightness set to max, I'd imagine 0.001ms wouldn't be far off the true result. However, they should really test BTB, or black to black, which is the time it takes for a pixel to turn from black, to white to black again, and this is the figure that Samsung did not quote, as it's a lot slower than 0.001ms (hence why black text on a white background shows noticeable amounts of blurring). But by my testing, I'd put the screen realistically, closer to 6ms.
And about the graphics turning to lower quality when scrolling, technically yes, this could be 'fixed' as its a software issue.
And yeah I'm sticking with Samsung, after I went through all those replacements, I finally got a decent one that has no issues (touch wood).
correct, as soon as the screen notices your finger it pixels the graphics ... argh! someone should disable that. it's 2011 and powerful enough!
and yes, chess patterns here too. even on less complex sites. never noticed that before in any preview-videos though. so again

thx for that explanation. for the pixel-thing I'll try to ask the developers here. at least it's android, so most things could possibly be done

Hi there.
Wondering if it's just me, but do most wallpapers seem to look really bad? I just put some hi res wallpapers I use on my laptop on my phone, but they all look terrible when set and don't get why. I have very few wallpapers that actually look good on my phone.
edit: Thinking about it, will they only look good if they're the same resolution size as my screen?
If you are using gallery to set them , and your pictures are high res , gallery most likely is messing up. Try setting wallpaper with "QuickPic" from maket and let us know if its better.
I9100 screen resolution is 480*800, so a wallpaper at that resolution will certainly look better. But as it has 8 homescreens you can also use 960*800 wallpaper, which will be a scrollable one, besides you can put a HD wallpaper too, you just have resize it by dragging the orange lines to the corners perfectly.
Regards.
You must mean the color banding you see. The SGS2's stock firmware has a 16-bit screen driver. The guys from Cyanogen hinted at making it 32-bit, making the screen look beautiful, but it'll take a long while.
Somewhere I think Samsung downclocked everything there is on the SGS2. Because now it all of a sudden charges faster than before, it's faster. And I wouldn't look up if they overclocked it to 1.5 ghz. I bet they have something up their sleeves for the 16-bit screen.
When I read what I just typed, I actually think that won't happen.. Mehh
Hi,
I have read a great deal about Super AMOLED plus screens having the best blacks because they physically dont turn on the backlight, saving power.
Now i have noticed, When viewing a black screen in the dark, there is actually a fair bit of light leaking through. even though it is "black light" (like on an LCD)
Can anyone else confirm this, or explain it?
Thanks
Its as black as black can be for me.

Perhaps the black wallpaper is not a pure black, instead it's a combination of colours to make it appear black.
I really can't see it in mine, but I've always wondered about this when looking for a black wallpaper. It's actually hard trying to find the darkest black using a PC, and wondered how you can really tell, as all black wallpapers would be a combination of colours.
I think it would be great for the power saving on the SAMOLED screens if you had an option to select "no" wallpaper or colour, so the background would automatically not actually turn on, using zero power.
This would guarantee you are using the purest BLACK and ultimately ZERO power on the background of your SAMOLED screen.
How does my theory sound
No Wallpaper and Colors apps in the Market will do a pure black wallpaper.
Use a microscope. lol
Actually it is a nice way to do it. Go to hobby town or somewhere and get a cheapy 10.00 microscope and you can look at the actual pixels. Not only can it help you here, but its always rather interesting to see.
Also, keep in mind that even when black, it still does have a little power in it, even if very minute, and still allows light a little bit, even if just in very very very very very minute amounts.
Ohh! Someone else has this to!
What happens is if you look at a pure black in the dark yolu will see almost white / grey areas, and it is not the image it is the same for everything that is 100% black , but is less noticible when something else in on the display, I also have a dark spot in the center of mine when it's on min brightness, Might send to Samsung, Or ask Vodafone they seemed to have a dodgy batch of phones.. this will be my 3rd
So I think it's a defect? The first phone I had didn't do this

Im glad im not the only one!
Yeah, I already sent my first GS2 back for screen problems, I dont want to have to send it back again and live without it for another 3 weeks. Also, I have subsequently flashed custom roms, so I would prefer not to.
If it ends up breaking, I'll just get the screen replaced when it happens.
Instal lcd test from market. When you see black,its like the screen is off...try it...
Sent from my GT-I9100 using XDA App

Excellent, thanks for the tip, it's as black as I'm going to get ;-)
I bought this phone 2 days ago, new, sealed, free from contract, and so far I love everything about it, except for this problem which I have found only today. I guess It was all the first excitement keeping me to notice earlier.
Like the thread's title says, it's like a perfect pattern across the screen, from edge to edge, consisting in perfect parallel 10-degrees-from-horizontal-oblique stripes. They are very very subtle and only visible on light backgrounds and more from looking from the upper part of the screen down.
Do not confuse them with the pixels matrix, whose density, by the way, is great. They are all right, and the effect described above seems to appear on a layer which is on top of those pixels.
To make an almost perfect comparison, this effect looks almost like the striped background from market.android.com (as seen on a computer), but with more subtle greish on white stripes inclined from right to left, and only like 10 degrees oblique from the horizontal. That is what's making me curious, why is that pattern oblique? If it were straight horizontals or verticals I would have confused them with the pixels arrays, and it would have been bearable. But like they are I can't stop but notice this pattern every time and it annoys me a lot! In GMail, Browser etc... all the apps with plain backgrounds...
It wouldn't appear on any close picture I tried to take, and I guess filming for you to see it isn't a good idea either, because you won't notice it. It's only visible with the naked eye, at a distance closer than 30 cm from the screen. It isn't also a problem of my eyes, because my wife is noticing it too.
Thank for any shared thought.

Much better to send you're mobile to the store were you bought it. because as what i have know the problem is the LCD. that is what they called wire stripe or ribbon.... maybe that is the problem. Try it, there is noting to lose.....
I see that too, only on light (white) backgrounds. I thinks it's normal, you may ask your local Sony Ericsson customer service or a phone shop, but I don't think this is a production fault.
On a dark blackground it is purely invisible.
Try it with and without the Bravia engine enabled.

sdk16420, thanks for sharing this, It is somehow a relief for me to know I'm not alone in this. Yet, I'll wait until next week to see if I can find more explanations, and then maybe I'll return it for a replace. It's especially bad for me, as I waited a lot to receive the silver one (a week or so), and I don't know if I can find another.

It doesn't depend on Bravia Engine, unfortunately. It was also the first thing that came into my mind, tried it several times, even with deactivating and rebooting, but the effect is persistent.
Again, it's only visible on light backgrounds, especially white and large ones (browser, gmail, etc). If you read this, please check yours also find some time to post a reply with the result. I would be very grateful.
Thanks!
I have the blue model but i can barely see that pattern with a screen flashlight (on full white) and i don't find it annoying at all in daily use of the phone.
You can check the screen from a new phone in a shop, to see if it looks like yours ... or you have a eagle eye
PS
check softpedia also
I think I can see what you're talking about on my Red Neo but only if I max the screen brightness and look really closesly (like practically inserting the Neo into my eye). 99.99% of the time I don't notice a thing.
I just followed your description and found the same with my neo, so I think it the LCD design. Not an issue to me indeed.
Does anyone have another phone model (e.g. Samsung, HTC) with a LCD touchscreen? Is it also visible on other phones?

I have a Samsung Galaxy S with SAMOLED, a HTC Desire with S-LCD and an Asus Transformer with IPS LCD, and they all have better screens. The Desire's is the most problem free, whereas the Galaxy S has problems with screen burn-in (or image retention, like some are identifying it, but for me it's still like the old good plasma screen burn-in ), and the Transformer's has light bleeding. But, like I said, when put aside, the Neo's looks the worst.
I don't know if you noticed it already, but it comes with another "feature" that is so annoying: it stays always on auto brightness regardless of the custom level set, maxing that automation on that custom level. It's so annoying, cause it's always too dark for me, and being a "feature" it doesn't have also a switch for that. At least it has for Bravia....

When I put brightness on 100%, and hold my finger on the light sensor, I don't see the screen getting darker. What does annoy me is that you can't make the brightness less than about 30%. I use widgetsoid for brightness adjustment, and the screen will only become darker than 30% if I hold my finger on top of the sensor. That sucks. I I want to sacve energy, I have to hold my hand there, while using the phone.
I don't see why people need the brightness that high anyways, aside from in some games with small hard to see details I'm perfectly fine with my brightness set at just 30% or even just 20%...heck I can still use the phone when the brightness is completely off though that does get a little hard to see everything.

I use it a lot outside, and its sunlight legibility isn't as good as SAMOLEDs or others, but that I knew from reviews before the buy. If it wasn't for the problem in this thread, I wouldn't be so harsh on it.
LE I se new posters here. Do you noticed the problem described in the first post? Does it bother you?
Okay, so the other day I somehow managed to drop a dumbell on my phone. So I got the entire screen replaced which cost $250 (screen didn't display at all).
Anyway, everything works fine...except for one thing. Some colours tend to give off a faint red "glow" to them. So for example, when pulling down the drop menu (CM10) the border around the notificifation icon (so around the picture of a cloud) is slightly red, and whe apps behind it (transparency) look a bit red as well. Plus, when it comes to black colors, it doesn't look as clear.
Hopefully that all makes sense. So pretty much, I told the guy that and he kept telling me that it's the software. So I completely reset it, the latest CM10 on it and still has the red tinge. Has the same thing no matter what ROM I put on it. Could it be that the graphics settings are all weird, or is it the job that he did on the screen.
What do you think?
Sorry if this isn't the right place, I just don't know what to do as I forked a bit of money to get this.
Might be a non genuine/non Samsung screen ?
Try gb or ics and if its still the same,go back to repairer for a fist to face discussion.
And you can get a screen here fitted for £80(so if your quote is u.s dollars youve been ripped off).
What do you want us to do? It sounds like a physical problem. You know the problem and you know how to fix it. Take it back to the guy who replaced the screen and talk to him. There is nothing anyone on XDA can do for you.
