When I look really closely at my Amaze 4G's SLCD screen, I can see a small horizontal line pattern overlaying (a lot easier to see at maximum brightness and with brightly colored icons). It's not really noticeable at a normal distance from the eye, but I was just wondering if my screen was defective or if anyone else has something like this on their's?
Also, I found that the moving objects in the screen (icons, menu labels, etc) tend to blur a lot more than the super AMOLED screen I had on my old phone when they're in motion around the screen. Is this normal?

I have the blur a bit too. I believe that is just normal. I'm not sure what you mean by white lines though, I can't see any on my screen.
I have the blur as well. I guess it is normal.
yeah i can see the pixels too, i notice this as soon as i got this phone as i had the sensation before and the screen on the sensation was muuuuch nicer even though they say its the same its not.. it was better in every way and yeah the blur when you move the screen in certain menus..i already complained to htc saying i felt like this phone was a downgrade from my sensation instead of an upgrade!
Ah okay so it's not just me. Thanks for letting me know, it's a shame that the screen isn't as nice, but it's not so bad that it's a deal breaker I guess
When my screen is off, I can see vertical lines. But I know that's the polarization of the screen... Can't do anything about it!

Touch digitizer maybe?
Not fine lines, there were like 6 or so and they were roughly 5mm thick. Now that I try to see them again... I can't 0.o They're gone! lol

with super amoled, if you use a black bg those pixels are just shut off and can save you some battery life. But the SLCD isn't as easy to see in the sunlight and i was curious if there is a difference in battery juice consumption with a white bg. Even black has to be luminated by the screen, not shut off pixels like S-AMOLED. Is there a difference between black n white on SLCD's battery drain?
I'm looking for a more technical answer with reasoning rather than "just try em both and find out".
White would be easier to see in sunlight without having to turn up the brightness past 25%.
Please don't quote me on this but I believe the difference in battery usage would be very negligible. It does take less power to display a black LCD screen than a white one but not enough to provide any noticeable difference in battery life like it does on AMOLED devices.

Thanks. I did just remember about a cyanogenmod setting to filter the color of the screen and it quote "potential battery saver". Im not sayin battery life is an issue, just curious on knowing the differences in power consumption by color. But like u said, its probably very minimal tho. My 2 past devices were S-AMOLED and I didn't bother with predominantly white backgrounds because it actually made a difference. Time to be able to enjoy the entire spectrum on SLCD without worry! Haha one of the few benefits of LCD

I think it might use more power on LCD screens. Or, at least, I remember reading that. However, back on my Hero, I tried the effect and it seemed to use the CPU more to render the effect. The phone got slower while in red, blue, etc. I think it is really only for AMOLED screens. Phones using that type of screen benefit a lot more. But I am most likely wrong. It has been a long time since I read up on this tweak.

that sucks that the phone becomes sluggish, but then again it was the hero which is 1/4 the phone the 3D is...
also, i'm trying to make sense of it being for AMOLED screens, cuz the pixels are individual LEDs (or so i think) which are on/off individually. but LCD is Liquid.Crystal.Display, which to me makes more sense to render the entire display a certain color... i dunno, probably talking outta my a$$ but hopefully someone with a definite answer can chime in..
thanks for all the info & opinions from you guys, i feel we're getting closer
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.

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?
Just noticed on my Lumia that there's a thin fine purple line on the edge of the left side of the screen. I can see more of it the whiter the screen is, can anybody confirm if they have this too or if it's just my device?
Thank you.
I have had two devices and both have shown some purple tint on the left side. My current example more evident than the previous phone.
Only noticable on gray/white backgrounds and not on colored backgrounds really.
It does bother me to some extend. Not enough to replace the phone a second time though (I did not exchange the first one because of this).
Not really like lines though. More like a subtle gradient that goes from far left into the right side.

Its only bothered me since I noticed it to be honest, mine starts at the top left, all the way to the bottom. It sticks out more at the top corner, then goes thinner as it goes down.
It's due to pentile amoled screen. And it's normal behavior.
What he said; it's a PenTile thing.
I have my new Lumia 800 with some strange shady lines after every item on the screen to the very right side of it, with white theme and with medium or less brightness. Should i return it for replacement, or every Lumia 800 has this annoying issue? Switching form an iphone 4 I was prepared for worse screen quality, but not this much... youtu.be/g8t_oRDpY70
I exchanged my phone for a second time even though I said I would not. It just bothered me too much. Took me three phones to get one with a screen that had good uniformity across the screen. Only the line bleeding visible at times but it does not bother me at all really.

That's an AMOLED 'feature'. I remember my Nexus One being like that, and when I set full brightness with light background I can make it out on the Lumia too.

It is not noticeable with black background, but ie9, office and some other application has a bright background anyway, sot it is annoying there. Of course it is not until you realize this issue exists, but after that, you cannot stop paying attention to that...
It's like line bleed on plasma screens... I feel like its imposible to get af perfect screen today don't matter if its on phones or larger screens...
my last two expensive flatscreens had some minor problems, Plasma was linebleed and so on...

I have to disagree with dk_iceman, iPhone 4/4S doesn't have this fault (don't know about 3GS, didn't own one) but fact of the matter is, this should be a fault, when we had such problems with our TV's, which even happen on LCD TV's, you get a replacement, I don't think such screen problems should be acknowledged as normal. Nokia have said for me to return my phone to them, but I'm checking for more problems, so I can give them a whole list of my expectations, I haven't had one problem with the iPhone 4/4S's screen, that's why I'm willing to pay more for a phone, this phone wasn't cheap too, so I think everybody should get what they paid for, ok software, can be solved, but for poor hardware, should be replaced. Agreed?

Hello all,
Just got my Lumia 800 and it's awesome. However, I've noticed a little problem where the "white" on the screen distorts a bit.
If you go into the Office App, next to the big title font ("Notes", "Documents", "Locations") and slowly slide the screen or scroll the body text. I'm noticing that the white adjacent to the title font distorts a little bit. I'll shoot a video later, but this appears to happen whenever there is a white background.
Does anyone have something similar?
Thanks in advance

When i first read this post I was skeptical, but then I checked and realized you're right...that's some weird stuff, it may have something to do with the pentile amoled, my gf's 710 (LCD) doesn't seem to do that.
It is indeed inherent to the screen type, my Nexus One did exactly the same, as does the Desire I have here.
Yep, looking at it closely you can actually see some very faint rainbow coloured lines on the sides of the text when it's displayed on a white background. This happens pretty much everywhere, even inside the xda app I'm using right now...
Yeah I guess if we're all having it, it's probably normal. Not ideal, but at least other aspects of the phone makes up for it
It's a little odd because it's not isolated to one part of the screen. It actually moves with the text.
It's normal behaviour and nothing to worry about. Amoled screens works like plasma TV's and it comes with its side effects such as "line bleeding" from text and other stuff.
Same thing Its irritates me very much. I wouldn't buy 800 if knew it. I bet that 900 won't suffer from the distortion

Heh, at times I wish I bought the Titan: big LCD screen highly enjoyable for games and vids, less artifacts compared to a pentile AMOLED, better battery life, removable battery and possibility of putting on an extended unit. What actually pushed me miles away from it is how big and stupid things looked on an oversized 480x800 display: at the end of the day you don't see more text on the screen, you just see it BIGGER, it looks like a phone for visually impaired people

It probably won't. The 900 has an AMOLED screen but it doesn't use a pentile matrix. The 800 has a slightly older AMOLED screen with one.
Samsung's Android devices have the same problem, Galaxy S - AMOLED pentile matrix. Galaxy S II - Super AMOLED no pentile.
Hello,
Im Using Amoled Smartphones since the Galaxy (i7500). They all were always showing at 100% Brightness for Black parts of a picture a true Black like the Display is OFF.
If you put the Brightness to 100% and go to an complete Dark Room and open an Black Picture you see some Gray/Yellow Tint on the Screen. You can compare this good by locking the phone to see the Screen OFF and than unlock it to view the Black Picture again. You should see a huge difference. Hope to hear from your experiences.
I've seen that already on the S1 when abusing it a a nightstand clock.
Best guess I've heard is that the (AMO)LED screen leaks some luminosity to other pixels in the background which is then visible as a very faint glow.
However I rather believe that the AMOLED are not truely off but rather get some leak voltage and thus have a very-very-very faint glow (like one photon per second xD )
That would explain the black spots most people seem to mind on AMOLED when on minimum brightness with a black screen; they are truely off or without insufficient leak voltagage (LED's requie a minimum voltage to work).
AMOLED production is somewhat complicated (very thin layer of silver as a power source and a control-layer) so I wouldn't be surprised if the above is true.
Nothing is perfect, especially not a rather new technology.

Yeah so I was wondering why it does this little/ hard noticeable yellow/gray tint on a dark room...
There is no Backlight... Unfortunely i Sold my Galaxy S2 so I cant compare it.. But im Sure it wasnt like this
I have this on my gsiii and also on the Gnote... I think is due to the pentile screen
I had this on my Fascinate but realized it wasn't a big issue. Definitely more noticeable on my Gnex but it also has more pixels so that could be why you see more light. I wouldn't call it a problem because the majority of the time it's absolutely unnoticeable. Each pixel has so have some sort of voltage to be ready to react to changes. Turning off/on completely each time light is needed might waste battery.
P.S. I'm noob at displays but that's my theory.

I was curious about this issue as well. It's my understanding that OLEDs do not produce any light in their inactive state.
Regarding your theory, I wonder if it's similar to plasma displays. Even though plasmas are capable of true black (they do not use a backlight) The individual plasma cells have better response times if they aren't fully discharged on blacks. So they have a faint glow that comes from the low power they are using to keep the pixel charged up and ready to go when a color change is needed.
This actually costs a little power though, rather than saving it. So if thats what they are doing, it is for screen quality reasons so that movies and other things look better.
Did some Googling and I couldn't find much information, but there is talk of delivering pre-charge voltage to the OLED pixels to improve response times. So it could be that they are indeed similar to plasma displays in that respect: Capable of true black, but the benefits of not using true black are too good to pass up.
Are you SURE the picture is actually true black? By that i mean pure 100% black in an uncompressed image? If not then you cant expect the phone to display true black. A JPEG of black may not be enough.
My screen it totally off when displaying true black.
I can confirm the screen showing a faint glow on S3 with a true black screen.
Use Firefox with Fullscreen extension (Chrome and the default browser don't seem to have fullscreen mode yet) and go to http://d4f.pf-control.de/black.html
That's rendered on the phone so we can expect it to be the blackest black an app can produce, however in a (very) dark room you'll see a very faint glow coming from the screen and you'll be able to see the black spots (truely black) that people keep complaining about.
The theory about it being a precharge voltage does indeed sound plausible since LED's have a certain reaction time which unfortunately cannot be compensated by e.g. Overdrive as is used in LCD screens.
Note that the S3's "black" is still far better than any LCD.
No mine is still jet black, no light at all.
Go to a COMPLETELY dark room and make sure the screen is actually turned on when on the website (not timed out).
Then take a long-exposure photograph of your phone (still make sure the screen is turned ON!).
I don't have a long exposure camera, but the room is completely dark and my eyes have adjusted, there is no light.
All sgs3 ( as sgs2) screens emit a very week glow on a black pictures ( with the screen on )
Sent from my GT-I9300 using xda premium
It would seem to me that the 'ink spots' many have are not overly dark spots at all, they are what the screen should be. My screen emits no visible light when displaying a true black image, at least nothing my eyes can see, even at the edge of my vision field where light cell are most sensitive. My screen is on maximum brightness.
My screen has no patches, no streaks, no spots, no pink or excessively blue tint. I guess i have a screen thats as near to perfect as they get.
yes there is very faint glow indeed making the screen a bit greyish instead of pitch black

I don't think anyone is trying to paint it as an issue that needs to be resolved. It's more of an odd technical mystery rather than a real problem. The blacks are still extremely deep on an AMOLED, just like with Plasma it puts LCD to shame in that department.
