oled screen issue?

can you guys try this out and tell me if you see this on your screens. first turn down the brightness and go to a web page with lots off black text. on my screen everything black leaves a faint line across the screen wherever there is a black pixel from right to left. do you guys see this? out is much less noticeable when the brightness is turned up.

I've seen a tiny hint of this in my screen, but it hasn't bothered me. If it's severe in your phone, you may want to contact HTC.

yes I notice this as well but I have to say that is only noticeable with backlight set to minimum, and i think it's a normal behaviour of an amoled screen. Now I have one question about the screen too:
When I'm watching pics or movies the screen has a very good resolution. For all the rest the screen seems a bit dotted and grainy, especially with text. For example in the app launcher where the app's names are written in white and the background is black the text is not extremely clear and if I take a closer look theres seems to be pink pixelss on the letter's edges. I can notice this thing almost evrywhere but I think it's a lot more clear to see with text and the backlight set to max. do you manage to see this too or do you think that's because i have a defective phone?

the grainyness on thin objects like text is 100% normal, its just how these OLED displays work.

This guy did some awesome research into the graininess issue using a macro lens on his camera. Really interesting stuff...

Eheh it's me that started that thread and i think that guy really did a great job trying to explain what's the problem... now i'm curious to know how many people notices this because till now it seemed that only me and that guy could see this "issue" so sometimes i'm still worried i have a faulty phone...it won't be a good thing since I'm from italy and getting a replacement phone wouldn't be very easy

My screen also appears reddish when i turn off the blacklighting in the clock app :\ maybe its defective?

No, mine experiences the same thing. Seems like reds are more biased when less power is given to the LEDs (not exactly a "backlight"). This is slightly noticeable on the lowest brightness setting too.
And mine experiences the "black line" issue too. I guess it's just how OLED screens work.

ok thanks, it's just reassuring to know that its not only my n1 experiencing this

Seen it slightly a few times. But never bothered me since I'm never in very low brightness that much.

HD2 pixels showing

Ok I just bought my HD2 from T-mobile like maybe an hour ago I was lucky that my friend works at the store and they got some in stock. Lucky me right? Well I just wanted to know if this is normal. I can see pixels and dots on the screen in sunlight and if the phone is tilted at a certain angle along with what looks like a crash hatch pattern of lines that also look like pixels. I called support to see if this was a problem they said no. The t-mobile model phone also did this. Is this normal and what is it attributed to? Thanks.

Yeah same here i dont believe its dead pixies as it follows a straight line and is organized. I think its the screen itself..Anyone can confirm this?

I read some where that it's for the capacitive screen to operate correctly and the iphone has this in certain spots of the phone. I guess it's normal unless someone else wants to let us know if we are freaking out or not?

it is normal and in all hd2 versions ,it is the capastive sensors

Are some people paranoid or is it just me. Obviously they are not dead pixels. Or else you would be able to tell when the screen was lit up. My wing had the dots. I believe it was for the touchscreen the crosshatch pattern is the capasative screen

100% it's the capacitive touch sensors...

paranoia abound in this thread. i think the dots looks cool. especially when they sparkle while the screen is off. never shows up with any indoor light so it doesn't bother me while inside.

[Q] Display issues on Omnia 7?

Hi guys,
I played with a Omnia7 at a local T-Mobile store yesterday. While I absolutly like the device and the colors of the OLED display I noticed a small issue: It looked like a few items (probably the ones beein showed most often) wrer like "burned" into the display. E.g. on a light background I could allways guess the Line "Windows Phone" and the logo at the top of the display. This stayed that way regardless what application I've been running.
So my question is if someone else ever notices things like that on her/his Omnia 7? I would guess thats due to the device beeing switched on all day long for months now so that the display has allready seen some sort of damage...

Nope, mine is working fine.
btw, i may experienced some similar issue on my previous device, the htc touch pro running wm6.5. some part of the screen just stayed there like a gloomy shadow for some time, esp when the screen is in dark backgrounds. i wonder if it is a design flaw or because of the ROM i'm running.

take a look at what happened to me! http://forum.xda-developers.com/showthread.php?t=973337

That happens to OLED screens if their left on for long.
One of the reasons we dont have the option to leave the display always on in our phones.
Generally it mainly only happens to display phones since their screen is nearly always on and stay in the same place.

Thats actually what I guessed, both.

I have my screen set to 5 mins (just for the sake if im on a game and dont want the app to tombstone and wait for a long reload)
But have no issues so far
The only complaint i have with AMOLED screen is the damn clarity is so poor compared to LCD's.
Where as it was crisp clear on SLCD on my HD7, the clarity on the SAMOLED screen reminds me newspapers wher you can see the squares in text and its not clear.

SAMOLED+ Pixel Response Time and Touch Screen Discussion & My Review of These Parts.

SAMOLED+ Pixel Response Time and Touch Screen Discussion & My Review of These Parts.
Hey all, I wanted to start a thread to have a discussion about these two things that are my only disappointments in this phone.
Let me start by saying I think this phone is awesome, and yes I feel there are a few other faults on the phone (lockscreen delay when running off the battery due to the CPU taking a second to kick in, weak GPS/wifi signal sometimes, heavy banding on gradients etc) But those are software issues and I know in the near future Samsung/Devs will sort this out.
But I had some big complaints that aren't (still I hope not) software issues. Firstly;
- Response Time.
By this I mean when you buy a new monitor and the response time is listed as 4ms or whatever. This is the time the pixel takes to make a full change. A slow response time will cause ghosting. And that's exactly a issue that the Samsung Galaxy SII faces. Ghosting.
I've gone through 4 replacement SII's for various reasons, and on all of them they ghosted. So it's not just my phone. Samsung bizarrely states the response time is 0.001ms which would be there would be no ghosting at all. However there is, quite a bit actually, by my testing the screen is actually around 6-8ms.
I want to see if anyone else notices it. I know there's been a couple of threads on this but I want to see if the majority of people notice this. Here's how to test, go onto white page with black text on, and then scroll down the page at a moderate pace, not to fast not too slow, try it at different speeds as well just in case you don't get it right.
The easiest way I find to do this is use the inbuilt stock news app, load up any story and it'll give you a long white page with black text you can scroll through. As you may notice if you got a decent set of eyes on you, the text will leave a trail. Also known as ghosting. To me, I find this absolutely unacceptable on such high end device.
- Colour
Also, as it's been widely reported and has been noticeable on all my GSII's, the colour temperature is very 'cool', nowhere near the perfect 6500k. As a result, white's look very blue. This is fine and you hardly notice it on it's own, however when I'm using the device at my PC, which I use on a 32" IPS panel TV I professionally calibrated, the whites on the GSII look more blue than the ocean! Technically this is a software problem and can easily be sorted when custom roms come along but jeez, this is some bad stock colour calibration.
Also when you tilt the display, the viewing angles are generally very good, however tilting the display by pretty much any angle adds an extra blue tint to the screen on an already blueish screen.
I'm an absolutely screen quality perfectionist so these points really get to me. Especially considering this is such a high end device.
Overall I'd give the display a 6.5/10.
After the colour temperature has been sorted, I'll give it a 7.5/10.
If the ghosting can get minimized somehow even slightly through software on top of that, I'd give it an 8.5/10.
Secondly;
- Touch Screen
Now we all know about the movement deadzone/threshold on the touch screen which is massively annoying, but hopefully that'll get fixed in the near future. But What I'm going to complain about is the low sensitivity of the touch screen is the best way I can describe it.
On my HTC Desire, I can tap the screen ridiculously lightly and quick, and the device will register the input, absolutely no questions asked. Absolutely brilliant.
However on the GSII the sensitivity seems to be a lot lower, I can tap the screen lightly and quickly and the screen won't register the touch at all. This is pretty damn annoying as sometimes I just tap the screen lightly normally and I have to retap things. Not very often but still. I wish the device was as sensitive as the HTC Desire.
In it's current state I'd give the touch screen an 8/10.
If the movement deadzone and sensitivity got fixed, it'd be a 10/10.
Now I'm sure I had more to write about but I've forgotten now. I'll edit it into the post if I can think of the other things.
Now as I said, I think the GSII is a smashing phone, sure there are a lot of niggles at the minute, but I know they'll get sorted soon. Just the points I've outlined in this thread are things I'm scared won't get sorted. But you never know, I'm really hoping they can get sorted/do get sorted.
As I said I've had 4 Galaxy S2's all had the above issues, and I've used 2 other S2's from friends who also have these issues, so it's widespread, I'm just curious if people actually notice it.
I've added a poll to the thread regarding these issues. Please don't lie to yourself about this stuff, if you notice it, please answer honestly

I honestly hadnt noticed any of this stuff, i even watched a video of the deadzone and couldnt replicate it myself. I also think the touch response is fine you must have a very light finger/thumb!
The ghosting i hadnt noticed probly because i dont read text as im scrolling i tend to go a page at a time and the fact that im too taken back with the smoothness that pages do scroll.
The blue tint you guessed it i hadnt noticed but then again its not often i hold my phone up to specially tuned monitors.. Then again maybe theres a reason for it maybe it helps reduce glare in sunlight, then again maybe im talking aload of ****e!
no offence but you sound like you could moan for england! chill out and focus on the things it does do well and you may notice the negatives less

Personally....I think your nuts. This is the best screen ever on a phone. I have none of those issues, the touch screen perfectly responsive, my whites are white as white can be. You keep getting your phone from the same supplier and that leads me to be what the problem is. mine is perfect in every way. lucky me I guess

Nah it's just I'm very picky when it comes to screens. And I definitely expect the best on such a high end device, unfortunately the SGSII falls abit short on this.
It's still a great device. Really wish I didn't notice this sort of stuff haha.

Best screen on a phone possibly. It's not the best screen ever though, it's good don't get me wrong, but not the best.
And I assure you, your device has everything that I outlined in my original post, it's just down to the user if they notice it or not. When I used my friends Galaxy SII's (who both got it from different places to me and each other) I asked them about this stuff and they had no idea what I was on about, so I thought my phone was faulty and I had a look at their GSII's and theirs have the same problems aswell, they just don't notice them. (They did after I pointed it out though muwhahah)

I must not have a sgs2. Maybe its because mine is from first batch but I have none of your listed issues. After 4 devices, it cant be samsungs fault.

Heh, guys every SGSII have these issues, I'm not arguing that, was merely checking to see how many people notice these issues (not many in the grand scheme of things apparently) there's quite a lot of reports of these problems so it's just down to the user

I guess I have horrible standards. No shadowning on my phone.

The ghosting and blue-ish colortemperature I noticed right from the start. But to be honest: I really dont care. At least the ghosting is nothing which stands out of the crowd... all of them have it ... HTC, LG, Apple. The only reason you don't notice it as much, is the lower contrast on the other displays.
As for the sensitivity: It's a little lower than with my htc hd2, BUT I'm actually glad it is. The sensitivity on the HTC phones is ridiculously high. You don't even have to touch the screen and you end up clicking something, which can be quite annoying sometimes. On the SGS2 I never had any missclicks, nor did I have any non-responsivenesses. Perfect setup for my taste.

I think all of the average joe out there probably doesn't care about all this minor issues. You must have the intention to find the fault of the phone in order to get what you want to find but do you think most of us would be doing this? Haha.. Tbh I don't really care as long as the phone does what I want without falling apart. lol..

Yeah I was a bit surprised by the ghosting, having seen the response time claims, but neither that nor the colour temp (on 'movie') have really bothered me so far.
What has irked me a bit is the image sharpness. On a site like m.engadget.com the coloured text on white background has a dark outline all around it, which to me looks horrible. Anyone else noticed that?

I think the ghosting issue is due to the low fresh rate of the touch screen.It's lower than 60HZ.
When you scroll the screen,the animation is not smooth enough,so you see the ghosting.
It's more of a visual persistence issue.
I remember when some choppy animation showed in CRT,I can see ghosting.
Never the less,when your finger leave the touch screen,let it scrolling itself,you can see the "ghosting" would be less noticible.
But you can still see it,that's because of 60HZ refresh rate of the Display.
I just wondering if there is any way to change the fresh rate of the touch screen.

What are you doing that's causing ghosting issues? There is a definite color temp issue but that's how every amoled screen has been so far. I would take a little bit of blue tint over the black color performance

The thing that causes the ghosting, as I said in my original post, it fast movement. The screens pixels can't change fast enough so things leave a trail.
As I said the best way so see this is to loadup a long page with a white background and black text and then scroll down at a moderate pace, fast but not so fast you eyes your eyes canty follow the line of text. If toy do it right and you've got a decent set of eyes you'll see that the text leaves a trail.

Yep, there's a lot disappointments with the screen on this phone. However as the poll is so far proving, majority of people don't care for quality as much as us. Only a few others care/notice about the things we're complaining about.

Thanks .. Thats the funniest **** i have read all day...
Theres nothing wrong with my sgs2 and ive owned Hero's Desire's Nexus One's and even an LG2X.. This phone is superb.. This dude does sound a bit anal..

Hey. I can definately notice ghosting on this screen if i purposely try to but as others have said, it doesn't bother me in the slightest. When watching films or playing games it's non-existant.
As for the whites, you yourself stated you can't really notice until you hold the device against your professionally calibrated screen. How are the blacks in comparison? Out of interest, how much was that screen/calibration.
I think the main problem with alot of peoples gripes is focusing on only the weaker aspects of the phone rather than the device as a whole. People want perfection which unfortunately doesn't exist in the world of electrical consumer tech.

now i see this horrible grey everywhere i cannot even look at my phone any more!
I hope that this issue would be enough to change my device!

Hey drm111, as you know I have those problems too.
Did you have them on all your 4phones?
1) As you know I have this topic in wich one screen had this blue ish coat on the screen, noticable from the angles you talk abouth. But the other one does not have it.
So maybe not everyone has that blue coating? Did you investigated that further?
2) As you also know there is this yellowish/darker 1/3 of the left screen, probably some don't notice it. You have to be in a dark room or in a light one really looking for it. You read abouth this huh?
But I you didn't post it here. Aren't you having this problem? And did you have it on al of your 4 phones?
3) Ghosting, yes i notice it to. No sharp text when scrolling,is that the ghosting too?
I have this first generation ipod touch, text stays sharp when scrolling. Should be the case here too.
4) Than you have the grey tints, wich turn pink. You can see it in the topic of nongrata23. But some phone don't have it it seems. Software or hardware?
We need to figure out what is 'normal' and what isn't. As I don't want to send my phone back if it is normal at this point for all the gs2 that are on the market.

Let me start by saying i used to work for a PC magazine and was among those who blew the whistle on the nVidia texture replacement fiasco surrounding the Geforce 5800. I can see a single texture out of place in a high FPS game, so my eye is VERY keen.
The colour of the SGS2 is slightly blue yes, but mine is no worse than the average LCD, including the Retina display.
Response time is seemingly slower than the previous AMOLED screens ive seen, but again is more than a match for the LCDs out there.
I would say samsung have made a trade off between the sub pixel density and other factors. It works for me just fine.
The 16bit thing is interesting. It looks to me like the screen isnt 16bit, but it is using 16bit at times. Thats a driver issue.

Screen viewing angle: really that bad?

Am I the only one not complaining about the Nexus 4 viewing angle? I mean, I have tried my best, but the screen really looks the same to me from any possible viewing angle...
Tell me your opinion :good:

It changes colour at off angles for me. It's definitely not great but I totally don't care. It's a phone, personal communications to me and I never look at it from an off angle. It's so much more important in a laptop or even a tablet.

The viewing angle is fine, what bothers me is that the Digitizer is detected quite easily, and it might be distracting sometimes.

Is something wrong with my eyes/screen?

top to bottom is ok but viewing in side angles from left to right turns into a different shade (blueish). and also in sunlight the Digitizer is detected.. annoying sometimes.
i wish google chose hardware more carefully next time (i know the phones only $350)but still. ..

I haven't even seen a complaint. I have noticed that looking at from a very sharp angle makes the colors darker, like an old projection TV, but I also wonder who looks at their phone on such a stupid angle.
People just like to whine about every little thing. They whined about the SIM tray rattling and it's almost impossible to hear. They whined about the speaker on the back emitting a slight buzz that can only be heard if you basically hold the phone in your ear.

I can see it a little on mine (Rev 10 211k), but I don't mind it. Gets slightly blue... I'm not complaining, esp. when compared to my Tablet S. Sony seems to have terrible viewing angles, although the Tablet Z is better. Still, are you guys really looking at your screens at odd angles with regular use? Your doing it wrong if you are.

It isn't bad at all, its just loopy ocd people complaining that they can't look at their screen from an 85* angle. Why they would want to? I have no idea.
