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.

Super AMOLED screen "Burn-in" problem observed

I own both Samsung Captivate and Focus, both devices have SUPER AMOLED screen. Both devices have burn-in problem after months of usage.
Captivate:
I could see the notification bar on top of the screen with the fuzzy clock and battery indicator burn-in to the screen with very pale color especially very noticeable with a white screen! I also saw AT&T stores had these demo units experiencing the exact problem! I then called up Samsung to replace the Super AMOLED screen. Now it's fine but very annoying.
Samsung Focus:
I just got mine in Dec and didn't use a lot on that device. There is a very good reason why WP7 has to hide those status indicators on top to prevent Super AMOLED screen burn-in problem. I also checked out the demo units in AT&T stores, all of the Focus had Windows Phone 7 logo burn-in to the screen at the top left corner due to the static logo constantly playing on the demo mode.
In conclusion:
SUPER AMOLED screen's quality life-time is still short compare to LCDs. Given about 2 months of usage, 8 hours a day with static image such as notification bars for example, burn-in issue is inevitable! In real-life daily usage, give it about 2.6 hrs a day, your screen will be burnt after 6 months.
NEVER USE SUPER AMOLED SCREEN WITH STATIC IMAGE!

On my phone the screen isn't on for very long periods. Even when I am talking on it if near my face the screen is off.
How does this compare to your experience?
Does a phone in demo mode have the screen on constantly?

The only reson OLED isn't so widely used is because of its limited life span (especially on blue color). From what I read in the past, it is very difficult to get blue channel pixels pass 2,000 hours of life span. Not sure if AMOLED or SAMOLED made any advancement in this area. So, the precautions should always be taken. Let your phone screen on 8-hour a day is not a good approach. That's why there is a setting to let phone go into sleep and turn off the display.
My Captivate has been working flawless since August 2010 with zero image retention or burn in.

How many hours per day do you keep your screen turned on? I would give that minimum 480 hrs with static image to experience burn-in. No need to wait 2000 hrs of life-time in Blue Channel in AMOLED.
The life-time of the entire Super AMOLED is here and I'm also being conservative: 480Hrs to start to get burn-in issue using AT&T store demo units as reference.

I use skype and bluetooth headsets alot, so screen shut down may not happen at all until i manually shut off the screen. Moreover, using GPS navigation will definitely cause burn-in problem with static images such as the miles, eta, notification bar, clock, battery indicator, etc.
Android is just not a good OS for Super AMOLED. WP7 on the other hand is for Super AMOLED.

I'd estimate less than 30 minutes total per day (only counts screen on time). So, 480 hrs should let me use my phone for 960 days, or way beyond my tolerance for an *old* phone.
If I'm sitting in a meeting broswing internet or reading news using some apps, almost all of them are full screen and won't necessary have static images on the fixed locations.
Turn the brightness down (I use auto brightness setting) and don't let the screen on for extended period. You will be fine.

I have to agree. The metro color schem (black in most of the screen) is the best way to reduce AMOLED battery usage and lower the potential burn-in risk.

I have both devices and neither or them display image retention. What method or program are you using to test this?
I downloaded a flashlight app on the captivate and on the Focus so I could turn the whole screen white. I also adjusted it to other color,s still see no burned in images.
I've had my Captivate and Focus since day one when they were first released by AT&T.

Go to any AT&T cooperate stores to check out all the burn-in screens. For captivate I use screen test. It cycles from white, black, green, red, blue, and other pallets. I can garauntee you that all Super AMOLED screens are the same given static images and keep the screen turned on such as notification bar, full battery notification, GPS app.
If you don't have any burn-in problems that means you haven't used the screen long enough even you got your devices since launch.

The key here is to keep the screen-on time as short as possible. For normal usage, it will be fine. Will it have burn in 2 or 3 years down the road? Sure, but I probably have to dig it out from the bottom of my drawer to check it out by then. I'd rather enjoy my sharp crispy and colorful SAMOLED for 2 years than worry about burn-in and settle for murky, low contrast and washed out color of the LCD screen for 2 years.
Store demos are the worse case senario.

Very true! But still people really need to beware of their SUPER AMOLED screen. But for gamers...... make sure don't allow a static screen staying on for too long.

Well, I was reading an email yesterday on my focus and noticed that the smiley message icon was like a little ghost in the background. I also noticed the circle/arrow icon. I use orange on black mainly. I moved the tiles around a bit, we'll see if it goes away.

No, it did not go away. It's only visible on white screens, but it is definitely there. I guess I'm going to drop by the at&t store to see if it's a warranty issue, but I highly doubt it. My guess is I'm stuck with it. Since I use the black theme it's not a huge issue, but when I switch to the white theme it looks pretty awful.

Why beware? Image Persistance can happen on any screen that is left running static for long periods of time. In most of the AT&T stores that I have been in the demo units are set to stay up and running for which I can only assume is to attract people. This will cause the image persistance that you are talking about. These phones screens also get used a lot more than your personal cell will.
Use your phone and don't worry about something that may or may not happen. In two years or less you will likely have a new one anyway.

Hilarious!
This reminds me of the times where projector tvs and lately plasma tvs exhibit the same not-suitable-for-gaming problem! LOL
That's one of the reasons I got the Motorola Atrix with its LCD screen!
My previous smartphone was a Nexus One and even though it didn't exhibit ghosting problems, I always tried to use it as little as possible and used the screen on its dimmest setting.
Now I can leave the screen on at full brightness for hours (like for GPS driving for instance) without any remorse!

They have been trying very hard in the past decade or so. The main problem is the blue channel pixels' life span. Most companies have ditched their effort and move to other technologies. That's the main reason why there is no consumer TVs made of the OLED screens other than the $4000 Sony 14" OLED tv.
Unless there is a scientific breakthrough, this situation will remain for years to come.

Has anyone dealt with Samsung Tech support on this issue I just got off the phone with them and they wanted me to do a Hard reset. I tried to explain that this was a physical issue, but they still wanted to follow their script.
Now they have sent me a label to send it off but want me to remove my SD card. It ismy understanding that this card is bonded to the phone and cannot be used in a replacement phone if they send me one. I am going to call them back ut based on my previous conversation I am not holding out hope that anyone there will know what I am talking about.

Be careful : Screen Burning on GS II !!!

Hi, I'm French so sorry for my English.
I use every day software called "iCoyote" to signal and be notified of fixed and mobile radars.
I've never let "iCoyote" running over 30 minutes.
Yet, I have a huge "Burn-In".
(on a I9100)
Photos (the last photo shows you how is "iCoyote" to compare with the screen burning).
My S GS II is now to the after-sales service since yesterday.

that does look really bad but the thing is if you are using that in the car and its infront of the sun as well it will get extremely hot...hopefully now that you have took it back they will sort it for you...but using the phone intensively it will get hot...just like computers or laptops even playstation..use them long enough they do start getting hot my friend..all the best hope it wont happen again

Dont these mobile screens have any threshold temperature values to turn off when reaching such temperatures???

Nothing to do with heat, research amoled displays. The more you use a particular color the less bright over time the color pigment will be. Blue lasts the shortest, then green then red.
On my old galaxy s, the clock made a set of "burnt in" pixels in its place. On an all blue screen, the clock had obvious burn in, green screen less noticeable, red not noticeable. One idea could be to lower the brightness to reduce the effect, but it WILL happen to some degree. For me it isn't noticeable unless I look for it...
The ring you see is actually not "burn in" in the sense of old CRTs or plasma, in fact its the opposite. With burn in, if blue "burns in" you always see blue. Amoled is the OPPOSITE. The reason the ring above appears to be redish-green is because the blue is "depleted" more so than red or green. As I said before the colors deplete at different rates, thus blue will burn out sooner than green, green sooner than red. So for the ring you see above, on a screen meant to be 100% white, your "ring" will be maybe 80% blue, 95% green, 100% red based on how much brightness each sub-pixel has lost.

Thank you for this answer. Now, I understand that the screen is "used" and not burnt.
Always using auto brightness.

I can see a difference in the notification bar area when I put the phone in landscape, eg in the browser.
I've got the phone about 3 months and a half ago.. I've pretty used the phone. Using auto brightness.

I noticed over the last few days some burning in. I went to start a thread to see if anyone else had this and there is a thread also underway in the Q&A section http://forum.xda-developers.com/showthread.php?t=1284984

That means any app that stays open (i.e. Car Home) can damage your screen. I had no idea, thanks. At least Car Home has the screen 90% black...

Thank's for the heads up and I will try not to use blue no more. (I did not think it would make a screen "burn out" so fast.) My 5 year old 32in Lcd hdtv I had dimed out to the point were it started becoming hard to see movies with dark themes. (I now have a 46in LED tv)

yep. I have Samsung Omnia II - first Samsung phone with AMOLED display. And noticed that time that blue pixels wear very fast.
It's pretty similar to plasma displays.

Yeah, a little research on AMOLED screens will reveal their struggles with finding blues that last anywhere near as long as green, much less red. Since it's an organic compound in the end, it's going to have a somewhat limited lifespan. How long it'll really last is going to vary by use, brightness, and luck of the draw.

Awww nuts!
That's a bit off-putting really but I'm glad I found out about the screen issue. I'm having a real to-and-fro battle trying to decide which phone to buy, Sensation or GSII. Each have their pros and cons.

when i had my mobile for like 3 days i was playing fruit ninja at highest brightness and all the slashing on the screen after 3-4 min i had a warning that screen temperature is high and it reduced brightness automatiacally but nothing happened to screen

Thanks for sharing this info, RaPiiDe. And thanks to ompuw22c for explaining this amoled specific issue.
Did anyone managed to get screen replaced, does warranty cover it?

My GS is almost 2 years old, but the screen is perfect. I guess that's because I set the screen the lowest bright unless I use it outside. Even though it's lowest bright, the screen is bright enough to do almost everything. I love superamoled.

A respectable night docking app must do two very important things right:
a) must lower brightness to minimum
b) must move the image left/right/top/bottom by a few pixels every so often , to minimize strain on pixels.

Just so no one gets confused here: "Organic" in OLED does not mean "material came from once-living organism, or is a product of decay". It instead means "made from an organic compound" - where "organic compound" is a material that contains carbon. Another example of an organic compound is diamond. Carbon is basically everywhere

I have terrible usage from PowerAMP in car mode. Just got my USB jig though. Will most likely send it in for replacement.

GT 7.7 AMOLED producing similar issues as the SGS2 and SGN

Here we go again, looks like Samsung hasn't really fixed any of the 'issues' with the AMOLED display.
I can clearly see the bottom half of my 7.7 has a heavy yellow tint compared to the top half which is whiteish.
Anyone else noticing the same?

My screen has no issues whatsoever, so far as I can tell. I just checked on a grey background to see if I could detect the yellow tint, and nope, it was clean and uniformly grey for me.

This being my first amoled display - I was blissfully unaware of "limitations" of this new technology. So I had mine on full brightness ( 70 -90%) for the first week I would say
Then I read some other posts like ths - then realised this was not a good thing to be doing. Its like plasma technology (although much better than lcd/led in terms of picture quality) it still suffers with the "image burn in" with static content. It took about 9 generations of plasmas to "cope" with this issue.
SO i would not recommend high brightness for the first week to two weeks to allow the screen to "bed-in" but I am not sure of how oleds function or they even need this.
I do have a very faint yellow hue that matches exactly with the system bar at the bottom. But off course the system bar is static and hides this all together. The problem is when you change oreintations - mine is 99% in landscape so not noticeable for my use.
However in portrait, this again is only really visible on a minimum brightness setting and against dull grey background. If I put up the brightness up to 25% it is really difficult to make out & any brighter I cant see it.
If it bothers you enough then to minimise static content:
1) Screen timeout from 1 - 15 minutes
2) I also now use "hidebar.apk" to hide the system bar. Can be a bit buggy but works on the whole and is free. Use it mainly when browsing for a long periods of time.
3) in the default browser you can change to full screen mode, in settings go to Labs -> select quick controls. This gets rid of the bar at the top.
Finally, full screen web browsing !! Also the quick controls are slick, once you get the hang of it. Just press on the extreme edges of the screen to bring it up.
Or just get a replacement. In your case it sounds bad enough.
For me I cant notice any issue 99% of the time. Even If I knew about the issue beforehand, I think the screen is just way better than anything out there for at least a year or two. You cant fault the rest of the tab - its pretty mint

just so people are aware, this screens "issues" are only for the neat pickers, they are not visible under normal usage condition when the screen is set to auto or manual
the only way to see those is when you set the brightness all the way to Zero
as long as you keep brightness at 20% or more you wont see any of that

Is this the same issue with the Galaxy S1?
On the bottom half I have an area that is yellowish on white pages. And when you look at a black image in a dark room the black on that area is more dark.
When you turn the display off and look against the sun or similar bright light source at a shallow angle you can see that the golden mesh is not flat in this area. it is bumpy

My screen has no issues whatsoever, so far as I can tell. I just checked on a grey background to see if I could detect the yellow tint, and nope, it was clean and uniformly grey for me.

Here we go again, looks like Samsung hasn't really fixed any of the 'issues' with the AMOLED display.
I can clearly see the bottom half of my 7.7 has a heavy yellow tint compared to the top half which is whiteish.
Anyone else noticing the same?

Pictures would be nice so we can take a peak, Im not sure how well it would translate but it should visible enough.
AllGamer said:
just so people are aware, this screens "issues" are only for the neat pickers, they are not visible under normal usage condition when the screen is set to auto or manual
the only way to see those is when you set the brightness all the way to Zero
as long as you keep brightness at 20% or more you wont see any of that

For me there is a huge difference between not having any of those screen issues and saying 'its only visible when X is done'. I prefer to have a flawless screen If I decide to purchase, the money back guarantee / refunds are there for a reason.
I use autobrightness as well and it does drop to 0% when Im using my device in the bed room with the lights off. of course I dont have a Tab 7.7 yet but this is how its been since my Galaxy S days and I've never had to do certain things to prevent flaws from surfacing, it was just flawless to begin with aside from the Pentile limitations on the text.
Then again your opinion, my opinion. I hope to see a flawless screen on the Tab 7.7 though but Im not expecting much.
But we shall see once its locally available.

Dude, the 7.0+ is probably better option for you. Save some money and headache because the technology is samoled+ not ++ or whatever the next generation is going to be called in 12 months.
I would say "normal" usage patterns and many will have flawless screens. Blast it at 100% brightness with a static image for a week - you will not be a happy bunny

Many will have flawless screens but you advise against it
I'll just have to wait for one that is flawless and purchase it, putting the stock keyboard in landscape mode easily shows this issue. For what its worth this yellow tint no matter how slight will show up in HD movies
Even with my phones Im more of an indoors user so my brightness stays either auto or probably fixed at 20% and I usally drop to 0% when web browsing in bed.
But I'll have to see it in person.. or its another refund process.
EDIT:
Believe it or not some review reviews on the Galaxy S2 and Galaxy Note in HD format actually shows a noticeable hint of yellow tinting.. I've seen 2 HD reviews/previews so far and it looks good. Hopefully it translates well in real life.

dont get me wrong. all i am saying that for me i have to go through the following to see something.
1) reduce brightness to 0%.
2) use third party app to dim screen below normal brightness threshold.
3) use third party app to remove system bar
4) change background to a dull grey
so it all depends on ur definition of flawless.
as i say under normal circumstances it is a non issue.

For me its just a 3 step process
1.) set the brightness to 0%
2.) pop out the stock keyboard which is already grey
3.) check for color uniformity
Heres an example on my Galaxy Note: I've cropped the pictures and its a little misaligned be the judge if Im nitpicking or not.
My 'normal' conditions involve using the tab at 0% brightness in about 85% of the time. But I'll have to see it in person to judge but going with that you said then maybe the RGB stripe handles discolorations a bit better.

What am I supposed to see?
I can see that the left part looks "normal" and the right half has yellowish gray colors.

Do you mean a ghost image? If so, it's a common problem of amoled displays. You must not being for a long period with the same image in the display. Do you know, for instance, that samsung as applied in the new S8 a almost invisible scheme to move time to time the virtual home buttons to avoid burn the display?

It's exactly that: a ghost image. It is the first time I notice that

Ok. It's common my friend, but most of people don't notice that bcause wallpapers are not bright enough or don't have regular colors etc. etc. For see the effect that AMOLED screen don't resist to much and burns easily, you can notice that in demo cellphones in retail stores. It's also the reason that sometimes they use videos instead static images...
There are a few apps in google store to fix that. What they do is being about 8 hours presenting strong colors to the screen alternately (I think for burning all the screen evenly). I tried some in my galaxy S5 but no results... Any case you can try...
The best thing to do since beginning to avoid the screen burn in is not abuse of screen brightness and do not use for a long time static images or images with strong sharp colors like the strong blue bar at top of Facebook...

we don't see that in his screenshots because screenshot is a digital pure image, not the image that he sees in HIS display. For us to see the ghost image in his display he must take a photo with another outside camera
If you want to notice that in your own phone try to have a regular white image in your phone above all screen area. Perhaps you can notice already at least the battery percentage, watch digits, or wifi or network scale in notification status bar place. Try it

Yes is a problem of all AMOLED screen phones, like plasma tv's - burn-in screen problem, you can search in internet. If your phone is a S8, is too new to be burned already. Also If you take those advises I said probably the problem take more time to appear. Any case I wrote any posts above too the Samsung trick with home virtual buttons to avoid or disguise the burn-in and ghost image of home buttons. It's one reason that I prefer physic buttons...

yes, more or less that you said. But first you must understand the technology. While LCD screens have a led light bulb that illuminate all screen and respective pixels (passive) and this ones not have own light, only take several colors, in amoled screen are the pixels who make the emission of light. This light of each pixel is too strong for it size. It's the reason why amoled screen is more detailed, vibrant colors, bright and with a infinite contrast. Now think, if you have a static image that is half white, half black it means that half pixels are turned on burning in the maximum while the other half ones are turned off spared. If this image are presented for a long time it means that half of pixels are already stressed while others are new in their maximum power of brightness. Now can you take easily your own conclusions why this happen and how can you try to avoid it? But it's only avoid a little bit, because in the end, there's no solution for it, unless you don't use the screen...

of course I can't secure to you how many minutes you must avoid to be on same screen! Simply try to avoid it as you can. For instance, I can tell you that my Samsung galaxy S5 suffered a display burn-in because I used S-view cover. The window area of the S-view case became dimmer (burnerer) because when it was close, only this area was illuminated at the maximum bright when notifications came like messages, mails or phone calls.
Also I became noticing that that area at the top of screen of notifications bar, wifi bar, network bar, battery and clock (that always is black) - in a regular color photo presentation that notification bar is not presented, that area was more brilliant because the pixels were most of time off, and also I could see the battery, wifi and clock ghost image. I became noticing that, after 6 months of purchased the cellphone...

If it's like that it must burn in the always on display part of the screen or the nav bar.

As you can notice, the "always on" objects are moving time to time to avoid burn in of those pixels. The same for the home buttons in the galaxy S8. The black bar or tab in the top, or the blue bar in same area of facebook or other app's like some browsers, whatsapp etc. there's no chance to avoid the dimmer difference between the rest area and this one, also ghost numbers of clock, battery and so on. Of course as much of bright you have in scale, faster will be the burn-in effect and more you'll notice ghost images or tabs.
Me, to avoid that also, I installed a black theme background, not only to save battery ( in AMOLED screens white illumination screen area drain battery) as also to avoid white and strong color areas, cause these ones burn faster the pixels
