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..
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.
Received my Note 8 11 days ago and I was now looking at a gray picture in my gallery when I noticed the navbar was already burnt into the screen (and the buttons, too). It's barely noticeable, but can definitely be seen if you know what you're looking for.
I've now checked my Nexus 6P which I've been using for a bit more than a year before the Note 8 arrived and it also has the navbar burn-in, but it's as barely noticeable as the Note's one, and that's scary. 1 year of usage and it has the same burn-in as an 11-day old Note 8.
Now, the question is: Am I alone?
P.S: Download a gray image (I've attached one for you) and view it fullscreen with max brightness to test it.
Not even gonna bite. If it's there, I don't want to know about it haha
I was really hoping that screen burn in was a thing of the past. My Note 4 had major burnin with the status bar at the top of the screen within the first year of owning it. It's ridiculous and one of the main things that makes me want to avoid OLED screens. LCD screens may be inferior to OLED in most ways, but at least you don't get burn in Burn in within a few days of ownership would have to be a record.
My phone is supposed to finally arrive on Monday. If this is a thing, then I'll just send it back. A lot of money to spend on a device with that flaw.

No burn in here and I've had my phone since 9/11. I use it A LOT as well.
Nope. No burn-in here also.
I haven't experienced any burn-in effects since Note 2, but I used that one for navigation almost every day for years.
On my Note 4. It's only there if I go out of my way to look for it. I'm sure the Note 8 will be the same. If you snoop around for flaws, it's there on all phones.
Not on mine. Been using since 9/6

Yea. My Note 4 is really bad, but it's also three years old.
But after only 11 days?
I have Note 3 since 2013 , used it for over 3 yrs as my daily driver and honestly I have no idea what do you people talk about, there is absolutely nothing resembling burn in on that screen, do I need to add there is no burn in on my new Note 8 either? Come to think of it over the years I also had Galaxy S3, S5, S8 and never seen burn in on those either. I've seen burn in on LCD screens, I couldn't believe it, I don't know how, but I've seen it, however after years of use.
Isn't navbar supposed to disappear after a while, until you bring it up again, or OP locked it in?
No burn in on my Australian Note 8, but it is only 7 days old...
what is the attachment supposed to show? im seeing this on a desktop computer and i don't see anything.
i took your poll. no screen burn in.
OLEDs will always be subject to burn in due to how they work. Since each subpixel is for a SINGLE color, they will age differently because they're not all going to be on at the same time (ex: a pure red will not have green or blue subpixels active, so red would age faster than the other two if left on for days). The larger ones, usually blue, will need more voltage to excite it than the smaller ones (almost always green, as we see more of the green spectrum than blue--look at a CIE colorspace chart and you'll see very little "blue" compared to green). More voltage = faster aging.
This will NEVER be eliminated, and will always happen using current OLED technology (read: need alternative to currently used organic materials not subject to electric decay/aging).
HOWEVER, don't worry about this. For a user to actually introduce image burn in you will need to have your screen BRIGHT (250+ nits at least) AND have a STATIC IMAGE being shown for DAYS.
I'm 99% positive that any image burn in reports, that have NOT done the above, is not image burn in but Image Retention (aka image persistence).
Image Retention is TEMPORARY, and is mostly from electrical build up in display components and will go away once the build up has discharged (pixel is off for a while). On LG OLED HDTVs there is an option to "clear panel noise" which is what this does; don't know if other manufactures have a similar option available.
Alternatively you can add build up to improve screen uniformity by looking at a pure white screen for a few minutes. (google "jscreenfix" to see what I mean by colored noise. There is an old jscreenfix.jar file that's no longer hosted on their site for offline and full screen use. I don't know if it would work on androids as it was made back in Windows XP days).
Again, I'd like to put emphasis on the difference between "image burn in" and "image retention". At a glance they will look identical.
How Samsung has their "always on display" may make finding which you may have difficult. It's possible that the screen is still getting power even with the phone OFF depending on how the circuits and internal components draw power from the internal battery (read: OFF may be an extreme form of SLEEP where the absolute minimum of power is flowing through components if they used some more exotic designs for the sake of reliability).
The nav icons move although it's much more subtle than the AOD, just enough to prevent their burning in. It's a little image retention, rest easy tonight.
Mine looks good
How to fix?
Mine there's a mark from waze report button so strong when the screen is white or more light.
No burn. Wife's S7 edge had Facebook burn terrible, and my S8+ had Google maps burn in a couple months. Screen burn occurs most quickly with screen at Max brightness.

Indeed. Very well written post. Thank you for taking the time to write it. My understanding is the same as yours. When I just read the OP's post I thought oh hell here we go again.

No burn in on my note 8 at all, but it's only 8 days old.
Got my Mi 8 from chinese aliexpress seller last week and noticed right away after turning the phone on that colors look washed out. Did some more testing later and noticed that some parts of display are really unevenly lit when using brightness under 50%. Also it has visible vertical lines in low light and low screen brightness. I get color banding in almost all gradients in images. I compared Mi 8 to Nexus 6 that I have been using 4 years now daily and the nexus screen is far better than mi 8. No banding, colors look great and I dont even get any uneven areas in low brightness.
Has anyone had any quality problems with mi8 screens?
I am yet to get response from seller. I would have bought the phone from local store with better warranty but they are yet to get any phones in stock.
My device is also affected by vertical color banding, more people have this issue.
Could give some examples?

I have not had any screen display/quality issues with my Mi8, however i have the newer 8gb/128gb phone version. There was a test done on the Mi8 screens, and they are Samsung OLED screens made by Samsung -the same ones in their phones (just cooler color tuning through software). Here is an in-depth screen review on the Mi8:
https://www.devicespecifications.com/en/editor-review/4f1676/3
I would have to agree that you probably have a defective unit, or maybe you have a refurb/repaired phone that they replaced the screen with a cheaper version?

Sorry for not posting anything regarding my screen situation. I have been contacting last 3 months every week to Aliexpress support trying to get this solved, seller won't respond and for some reason I can't get warranty, they wont tell me why. My old Nexus 6 died a while ago and I had to use this piece of crap now. Below you can find picture regarding the problem. Its not glare from external light - screen has this inequality and banding can be seen too. Compared to my nexus 6 of course. Both phones at ~50 % brightness in complete darkness.
I might try sell this phone for as faulty or get some kind of compensation from seller and then buy 6T. No more xiaomis' for me.

Hi All,
I am about to take delivery (Tomorrow) of an imported 8GB/256GB Sim free Mate 20 Pro twilight in the UK.
Is there anything I should be wary of?
I am normally (dare I say it) an Apple fan boy ... There I said it! (Current phone iPhone X)
I have gone for this option for 3 reasons.
1. The added ram and storage space over the 6GB/128GB model.
2. It will good to have the dual SIM functionality, I normally carry around an iPhone X (Personal phone) and an iPhone 6 (Work phone), I would like to do away with 2 phones and just use the one.
3. The camera setup seems fantastic, I do a lot of photography both privately and while at work.
I see a lot of complaints about green bleeding on the screen, is this still a problem on the 8GB/256GB model? If so, what can I check for once it is delivered, ideally for a fast return of it if need be.
I have ordered from an eBay seller who advertises that the packaging is opened and a UK charger is supplied and that the 1 year warranty is with them. They have openly admitted that they are imported from Hongkong and Singapore.
I cannot find another UK seller selling this particular model, the only one selling with the dual sim function is only the 6GB/128GB version on Three with a 24 month contract, which I am not interested in.
Thanks all.

You can download Device Info HW from the play store to see what type of screen you have. BOE vs LG. LG are much more common to hvae the green screen issue develop, but it's not exclusive. And not all LG screen are bad. You can also check the serial number. In the middle will be an 18, letter and another 2 digit number. This stands for 2018, then a - october or b november and the 2 digit date of manufacture. Later dates seem to have a better chance of no defect.
Then download Mate 20 Pro screen tester also from the play store. I think it's just named screen tester. You can then lower the brightness level and go to a dim area. This will show any defect if it exists. Also using performance mode, and using the provided fast charger seemed to develop the problem, or it may have just been a coincidence. I can't say for sure. Good luck! hope you get a good one.
Thanks for the info,
I hope a get a good one too! It's going to be a hard transition from iOS to Huawei, I used to detest this brand in its early days, but WOW!! they have come so far, I am very impressed.
Slightly off topic, is there an easy way to move all my iCloud stored photos and videos etc across to the Huawei?
Does the twilight model have more chance of green screen??
I hope not!

Still going strong! :good:
I have a 128GB UK version I purchased at launch with an LG display and planned to upgrade to a 256GB international model with a BOE display. I ended up returning the 256GB version because to me the LG display seemed way superior.
At least some of the hysteria generated on XDA about the defective LG displays was nonsense.
It is normal for a folded OLED display to have screen bleed at the edges and it is also normal for a folded OLED display to show lighter around the edges when doing the screen uniformity test that purportedly showed that the displays were defective.
People were making comparisons between the standard OLED displays on Samsung phones and the folded OLED display on the M20P and since the results were different that was supposed to prove the LG displays were defective.
On top of that easily 70% of the initial reports of defective screens on the XDA Gluegate threads came from new XDA accounts that appear to have been opened specifically to report defective displays.
The BOE displays are much less bright than the LG displays at every illumination level including 1 which is why people don't see the scary light bleed eminating from the display edges.
That difference is very obvious if you compare both displays side by side.
The LG display also has much more vibrant colors and way better contrast.
Hi,
Thanks but I totally disagree regarding the screen quality.
After mine arrived I went into a Three shop who let me play around with a 6gb/128gb and side by side my BOE screen vs the LG screen was better. Also the brightness levels are either the same or if anything the BOE screen was slightly brighter.
The only bleed I can see on mine is 2 vertical lines right on the bend and this moves depending how I look at it, indicating that as you rightly say, it isn't screen bleed. The phones with screen bleed (Including the one in the store) was very very obvious and filled nearly the whole screen. Staff claim it is to do with the lights on the shop, but clearly that isn't the case.

You're in the minority. I had the LG and the screen was awful Truly awful. Green which is visible on all LG screens to some degree ruined the screen even at 50% brightness.
This is just your attempt at feeling better for having an LG screen.
My BOE is perfect and better quality in every way than my 6 previous LG replacements, which all had the "green bleed" not "off angle discolouration". Don't try to make out we are all confused, it's you who's confused and spreading nonsense.
Huawei confirmed to EE that the LG screens are defective which is why EE replaced mine 7 times until I got a BOE
BOE is just as bright. Just as much contrast. Just as sharp. Not faulty.

My BOE replacement is pretty good also. Brightness and clarity is great. No dead pixels and no uniformity issues even with screen tester apps.
The LG screen was defective that I had. And many others have had. Not all LG screen in phones are defective, just the implementation in the mate 20 pro's for many people.
I think the edge bleeding is not necessarily normal, but rather a function of an inferior polarizer. The same reason LG and BOE are slightly more off tint when viewed from an angle. That same angle is produced by sending the screen. I still believe Samsung makes the best screens.
I also noticed that the BOE screen has some GHOSTING. If you have a BLACK background and scroll up/down with white text or windows. The white will momentarily be grey/purple lagged until the pixels catch up. But isn't something that will show up with a grey background, I think this is because the on/off function of the pixels is slower than other transitions. NOT a defect, just an observation. Haven't tested on a Samsung or LG screen. Just noticed while evaluating the BOE.
*Edit* seems it's black/grey that shows it.
Just found with a quick search, one that shows the purple lag.
https://www.reddit.com/r/GalaxyS6/comments/34t923/is_your_screen_defective_test_for_yourself_by/
Just scroll.
*Edit #2* just tested on my wife's Note 9 and there is just a hairline lag of purple that resolves quicker. Instead of half the grey square.
*Edit #3* just created another thread to discuss the ghosting separately.

This is an inaccurate statement, not all LG screens are affected.
My M20P was preordered before the October launch from O2 UK (so presumably a relatively early model) and I have no issues with any visible green at all at any brightness setting.

"green which is visible on all LG screens to some degree". Nope, not visible at all on mine, which has an LG screen. I've seen examples of the green issue, and mine is uniform black across the screen.
Have a friend who had a BOE screen on his from EE, and the two screens are unnervingly similar. Nobody would look at images on both and state that one is better than the other.
So care to try again?
