[Q] Galaxy S Deteriorating S-AMOLED Display - Galaxy S I9000 Q&A, Help & Troubleshooting

I recently compared my 4 month old Galaxy S-AMOLED display with a recently bought one.. There is visible difference between the maximum brightness in both screens. The newer one looks brighter with better colors when compared to my older Galaxy S. Both are GT-i9000 international version, and I used similar images to compare the screens..
Does the Super AMOLED display deteriorate with time? Also please tell me if this will covered under warranty..

It does deteriorate quite quickly. Especially the blue pixels. Not keeping it on high brightness levels helps the screen deteriorate less quick. And I'm not sure but I had read somewhere that when it comes to "burn in" if the effected area is greater than 8 pixels then you can replace it under guarantee.

Yes every lcd screen would die one day but Super AMOLED dies with burn in faster, but still would give you 3-5yrs of life.
On daily basis keep the brightness to low or lowest when you need to brighten up put finger on notification bar & slide it to right (bright) slide it to left (dark).
Hope this helps you to get more life from your lcd.

thanx a lot guys.. will go for warranty and let yawl know how it goes..

How dark can the screen brightness be set?

Strange question maybe but being SLCD I think I am right in saying the blacks will not be as black as a SAMOLED screen and that the brightness of the screen overall cannot be dimmed down as much as other types.
My question is whether the brightness can be turned down enough to be comfortable in the dark when reading text or does the brightness practically blind you even at its lowest?
Incidentally, just how black are the blacks?
I would say if you've seen an iPhone 4 the blacks are similar to that. Not nearly as good as amoled but still decent. And you can manually lower the brightness to a pretty low level. It doesn't strain the eyes in the dark. The capacitive buttons on the bottom are actually brighter at the lowest screen setting.

Thanks for that.
My first experience of slcd was with the dhd, I've also seen the slcd screen of the nexus s and can't say I'm that impressed with either black levels or ability to lower brightness to a comfortable level. Hoping for better from the IS but somehow think I'm being optimistic.
There's always screen filter from the market but that's not nearly as effective on slcd as on samoled in my experience.
Swings and roundabouts, always!!

The Desire HD does not have a SLCD display, only a normal one.
OK buy either way its neither amoled or samoled so I'm sure you get my point

[Q] Image burn on a captivate?

Has anyone experienced LCD image burn-in on their captivate? I just noticed yesterday that when I have a web page up I can look on the left side and see Pandora Radio's controls.
well modern lcd's dont expereince burn in and the captivate doesn't have an lcd it has an oled tft not lcd tft. specifically it is "super" amoled. yes amoled screens are suseptible to burn in but not as much as standard oled. however it is very apparent on att display models in the stores. that said i run mostly dark themes and dont have any burn in that i can see, my phone is coming up on a year old.
Edit: Beaten to the LED thing.
Just to clarify, the Captivate screen uses LEDs, not LCD technology. That said, LEDs are much more susceptible to burn-in, and my screen has it. It's most noticeable around the notification bar clock at the upper right, since it's almost always displayed. It's most apparent on solid or almost solid screens.
It doesn't really bother me, I guess.
Perception 10.2 | Onix 2.0.4 | I9000UGKC1
well leds aren't suseptable to much loss of brightness but oled technology doesnt use the same type of semiconductors. it is organic light emitting diodes. the organic material deteriorates over time.
in oled there is no lcd or backlight. the organic led's are the pixels
dont associate oled too much with leds because with lcd's led backlights are far superiors to florescent backlights. not only in color balance and temperature and power consumption but also in longevity.
Thank you guys for your replys, it doesn't bother me too much. I was just checking, I leave Pandora up all the time while I am at work and now that I have this information from you all, I know to not do that so much.

do Samsung make different screens for the Samsung galaxy s

Hi
i have two Samsung galaxy s i9000
One screen looks a bit dull and slightly pink and the other looks really clear.
The dull one is old.
Both have been flashed with the same Rom and are both set us the same
They should be all the same. Are both phones the same origin-carrier?
Sounds like a problem with the pinkish one. Is your kernel voodoo color enabled ?
(But if the phone is old, it may be that the screen is getting, well, used.)
we sell phones, we have brand new and second hand units, regarding the lcd... sometimes if we change lcd screen theres a different resolution between the china-made lcd which is cheaper than the original lcd we sell. did you.change the kcd before? is it second hand unit
Neither phone has had a screen replaced. I've had both from new.
The pink on is 14 months old and the other is two months old.
Only noticed the old one looks poor when i got the new one.
Ill try take a pic.
Will have to use each phone to do it no camera.
A video of quadrant would really show you. Ill see if i can use my mates phone later
Im sure i read somewhere ages ago that the screen can get burnt like with the really old big back monitors do you think it could be that.
There are no marks like battery or the signal bars like you would expect.
Its like someone messed with the colour and contrast or something
they are both amoled screens, right?
usually it shoult last longer than one year, but amoled has a really short lifetime, compaired to all anorganic screens (e. g. LCD)
expecially the blue subpixels (physicaly more energetic than read light) gets weard out a lot faster
and organic screens get weard faster if they get hot or warmer than they should (cooling the screen extends lifetime (in a bag <-> close to the body)
but this are just some background informations, i cant really imagine that a amoled screen is used up in around a year
try to flash a new and a same ROM
then tell us
this may reset all reselutıon parameter on both of them
Maybe the new one is Galaxy SL. Samsung stopped production on i9000 and started making i9003 with super clear LCD displays. Maybe the new one is that.

But amoled has better quality than sc-lcd
But Super amoled screen display a pinkish white when viewed from the side. This was eleminated when Samsung put sclcd displays. So, the old one may be amoled and new one sclcd

AMOLED has better black and bright colors, but it's less clear and has problems with some colors. Mine, for example, has problems with gray: it looks terrible and it turns to red on lower brightness. AMOLEDs are also very different, one producted batch of screens can be pinkish, other one - blueish, third one - yellowish.

Thats right, middle brightness is not so clear.

[Q] Is it me or everybody facing screen burn issues with Moto X?

My Moto X screen looks too yellowish compared to other LCD display phones like Nexus, iPhone's etc. Is it the issue with Moto X's Amoled display or something is wrong with my device?
What you're noticing is just the inherent difference in color reproduction between AMOLED and IPS displays. Most IPS displays have cooler color temperatures and do a better job at producing a true white although with less color saturation.
That being said, I have gone though 2 Moto Xs and the first one came with a very poorly calibrated display and a gross greenish tint. My second one was much better, but I returned it for other reasons, future burn in being one of them. Burn in is different from the problem you're seeing and can best be described as bad tan lines. Some areas of the screen will have different brightness (mostly the nav and notification areas) and it will be obvious when you switch to landscape mode that something isn't right.
If you think something is wrong with your screen and still have a valid warranty, give Motorola a call and let them know about it. They seem to be pretty good about making things right.
No screen burn for me... Had the phone since January and mostly a heavy user too. Maybe no burn because I keep the brightness level down most of the time?

Frankly, it's just a case of not taking care of the fact that we're using OLED tech which is sensitive to static images much like Plasma tech. If you're on Kitkat and use transparent bars like most of us: I can't imagine how anyone could suffer from burn-in that won't go away with time.

But I did not keep it long enough to notice burn.
No burn in here, but I use fullscreen so I don't have a notification or navigation bar.

This is absolutely wrong, no offence. IPS displays do not have any cooler colour temperature! They are less saturated than AMOLED displays mostly, and thus the colours look less vibrant, or more accurate if you will. At the same time they will look extremely dull / pale. If possible just look at the S5's display, it has the best white I have seen in a while, neither yellowish or bluish, near perfect.
And yes, I agree with OP, there is a slight Yellowish tint on mine. This reminds me of the the Galaxy S2's display panel. There is nothing you can do other than getting adjusted with it, but you can try increasing the Blue bias of the screen, to something like +3 or +4. There is an app called Screen Adjuster on Google Play to do that. I am using that now, never thought I would have to use it again since S2 days. By increasing the Blue bias the screen will look little "cooler", the Yellowish white will become Bluish white.
This has nothing to do with burn in by the way.
I should have been more clear about that. It's the backlight source that affects color temp the most. Since most IPS displays use white LEDs for backlighting they appear cooler than many (not all) AMOLED panels and older TN displays using CCFLs. Since the individual pixels are their own backlight with AMOLED there is more variability in color reproduction depending on use and calibration.
And it does have something to do with burn-in. If you have a mostly blue background then those subpixels will see more use than the red and green subpixels. Once the blue subpixels fade enough you're left with a yellow tinted screen. It's not burn-in in the traditional CRT sense, but it's still uneven wear. IMO: The small perks of Active Display are not worth having a screen that can be damaged by normal use.

Questions go in the Q&A section.
I called up Motorola customer care and they asked me to visit nearest service center. They will have a look and decide if anything is wrong in the device. So, this yellowish tint is bit common in Moto X due to AMOLED screen.

It can be. There's a member around who got like 4 replacements or something....all with different degrees of it.
I find you don't notice it after a bit.... Unless you put 2 phones side by side.
Personally it doesn't bother me....it would if it was too yellow. I find the dimmer the screen, the more you notice it also.
My first moto x I had since October got burn in around January. I got a new one in June and I have burn in again. It isn't enough to warrant another replacement (yet).
Can someone explain to me how this phone suffers burn in? Burn in is a thing from old CRT televisions, not really the new LED screens (at least, to my knowledge)
i've always used gravitybox to give the statusbar a grayish color instead of black (and here lately the tinted statusbar xposed module) and keep it in expanded desktop with pie controls, so there's no nav bar, and not seeing any burn issues yet, had it since Dec. the horrifically bad burn in on my note 2 is what made me want to be extra careful with the x.
No burn in here after 7 months on mine nor my sister's Moto X.

Burn in is common in amoled type displays, specifically on phones such that rely on a nav bar instead of capacitive buttons. The longer the screen is on, or the higher the brightness, the bigger the possibility for screen burn in . Out of the three amoled phones I have owned, the two that have burnt in both had on screen nav bars. I hope this (non technical) summary helps

[Q] Planning to grab the Nexus 6, few questions before

Hi,
I'm planning to get the 64GB Blue Nexus 6 and i have a few questions before i buy:
I heard that the AMOLED Screen have some issues like burns on the screen. Is that true?
Also i heard about "pink" issues with brightness. This is true also?

The at&t variant I personally own never gave me these issues. I have read the pink tint issues were associated with the adaptive /automatic brightness enabled?! Yet, on mine I saw no pink with it enabled or disabled.
And there are videos on YT showing burn in. It is basically the soft keys at the bottom. Triangle, circle, and the square are the culprits. But again no issues for me.
Now the very 1st day my phone did a random reboot on me - twice! But, as soon as I unlocked bootloader, rooted it, and used a custom recovery the reboots never surfaced again! Go figure?! And the nexus 6 is definately the fastest performing phone I owned yet

AMOLED's can all have that issue, but I personally have never seen it happen (I have had a gnex for almost 2 years which used AMOLED and doesn't have burn-in). The pink "issue" isn't really an issue, google allowed the screen brightness to go extremely dark on the N6. This causes the screen to take on a pink tint simply due to the way amoled's function at that low a brightness. The screen does have a warmer hue to it as well because it is AMOLED, but you can use a custom kernel to tweak RGB values and give the screen a cooler tint. Hope that helps

Thank you for that useful information mate.
So, all AMOLED's, regardless if it's the N6 or not, suffer from this issue?

That is correct, all AMOLED's are susceptible to this because of the O in AMOLED, which stands for Organic. The organic compounds that are used in these screens are susceptible to burn in due to the fact that the organic compounds degrade with a lot of use. Of the RGB subpixels, Blue subpixels degrade quickest. However, the N6 uses a Pentile pixel arrangement. This has upsides and downsides, but it is actually an upside as far as this issue is concerned, because the Pentile layout contains less blue subpixels, so there is less susceptibility to burn in.
If you want to combat this issue further, you can use blacked out google apps, and use ROM's with blacked out system options, use a mostly black wallpaper, etc. This is because on an AMOLED screen when the screen is black, the pixels are not displaying any light and thus are not degrading at all. This should reduce your chances of running into the issue. It will also save battery life since the screen is not using as much energy. That is one of the upsides to AMOLED screens, along with the very dark blacks you get in movies and games for the same reason (pixels are not lighting at all). Like I said, I've used other AMOLED screens and not run into this problem as of yet, to my understanding it should take years before you start to see burn in even with normal use. Some people say they have issues right away but that has not been my experience.
All screens of any technology are correctly color calibrated at a given brightness and are very far off at extremes. With an LCD, it will generally be too blue at high brightness and not blue enough at low brightness. That is because the backlights are never a 6500K source. They are basically always bluer than standard.
The Note 4, to pick an AMOLED example, does not get red at very low brightness, but that is because it (according to others) has a higher minimum brightness. My screen takes on a red tint when in a dark room with adaptive brightness enabled if I have the brightness slider set below about 30%. I consider this a handy feature since I don't like the feeling of staring into a light bulb.
Above about 30%, or in a room with a light on, the screen stays normal for me.
I have not seen thecpink issue on my N6 at all.

Not sure about the bottom paragraph, surely you mean inverted colours? Also If you use a mostly black wallpaper you're more likely go get burn in because the pixels around navigation buttons aren't on at all and are thus not degrading whilst the navigation buttons are fully on and are degrading.

Inverted, blacked out, I don't think there's a difference. The button icons themselves will eventually burn in because they are almost always on unless you opt for pie like controls, but like I said that should be over a span of years. A black background will keep everything else from wearing faster though and should give you better battery performance.
I have had the phone for a week now and have not seen either of these issues. I do keep my screen fairly dim, like minimum brightness PLUS a screen dimmer for the nights and early mornings. I do not see any pink what so ever with adaptive brightness off and the minimum setting for brightness. I only turn the screen up when outdoors. I don't know I just find the screen really bright while indoors and I would assume burn in would be more susceptible with higher brightness
So i can safely buy the device right?
Anyway i have to order the phone overseas (No 64GB avalible in my country and the price tag too high anyway).
