Is super amoled screen dying

SGS screen is awesome, even if colors are not really well calibrated...
Yesterday, I saw a recent Galaxy S and it was really brighter than mine (4 months year old)
I noticed a huge difference!
Did anyone of you got the same experience?

Insulting question perhaps, but did you check the brightness slider of both phones?

Same rom, same kernel, same phone, same country, same settings. I'll try to post some pictures

We just got 4 at work. The supplier told us they only had 1 left a few weeks ago and we had to wait until they got new stock so when they turned up we had one from an old batch and three newer ones. The one older one was very noticably darker then the 3 newer ones even with exactly the same screen settings. It also had a slight blue tint to it.

My brother and I both have I9000 Galaxy. The 1st phone (the older one) was very bright that it resulted in eye strain while using!
After about a month when I bought a new Galaxy S it was very dark compared to the older phone on same settings and same firmware.
So maybe its the issue with some phones or I am guessing that the older phone suffered from backlight bleeding! But now the screen broke and I bought a replacement screen from ebay.

Now THAT explains something. I have a pixel tester and when I set it to black, in a pitch black room I can still see the screen. Well now I know... You sure about that though? Even the Samsung Super AMOLED videos make a point of there being no backlight.

AMOLED does die over time, blue first. So as I understand it most of these AMOLED screens in phones have twice the blue pixels to make up for it over time. I would of suspected that the lifetime is a few years though, not months.

There is no backlight in S-AMOLED displays.

As you can see, there is no lamp, neither a white background needed for the light to reflect.

Thought so. So, can anyone explain to me why I can see my screen in the dark when the phone is showing only a black screen? Such as with the dead pixel checking app I used? Perhaps it does not correctly request true black but even noLED from these forums does it.

I would expect it's due to leakage current.
Each pixel on the screen is controlled by a transistor (actually probably more than one). Even when the transistor is turned off (and the pixel should be dark) there will still be a small amount of current leak through. I suspect that this is what causes the screen to glow slightly even when displaying black.
Of course when the entire screen is turned off, no power is going to the display, so even this small current stops and the screen is darker.

Maybe Samsung has switched to SLCD screens.
The rumour circulated few months ago that Samsung has stopped the production of the Wave and the Galaxy S smartphones because of the Super AMOLED shortage.
Maybe now they are shiping SGS with SLCD.
The SLCD screens are much brigther than SAMOLED.
Here is the comparison:

I highly doubt samsung would discontinue the SGS line for any reason. In fact, they just started to showcase the 7inch SAMOLED most likely for the next gen galaxy tab.
However, here's a comparison.

I'm sure it was an AMOLED Screen, easy to recognize...
I'll try to make some photos.

i got mine when it first came out and i have it on zero brightness setting and it is bright and clear (except in sunlight when it becomes as hard as any other phone to see)

ive tried about 15 of these phones and the screens on all of them were different when set to the highest brightness. The most common differences were darker and lighter shades of blue. a couple were more red than others and looked 'warmer'. The one im using right now is pretty neutral though not sure why that is but they all seem to be different.
(all 15 were running JH2 stock with no lagfixes on i9000m from bell)

Argh...
I have a dead green pixel towards the bottom of the phone... And now that i know its there.. I keep looking at it! Def wasnt dead when i got it
A good way to test the pixels is via the *#0*# menu... red, green and blue.

i always have brightness settings at the lowest and when i was using eclair rom everything was really dark. after flashing froyo rom i noticed straight away even at the lowest settings the phone is still pretty bright but green colour does not look good at all.

Question about amoled burning in

This is my first amoled device, coming from the atrix (LCD).
I don't generally leave my screen on when I'm not using it and I try to keep brightness as low as possible.
Does the pentile pixel arrangement on the sgs 3 provide any benefit to preventing burn ins?
Can I expect to make it 2 years with this beautiful display?

I'm not an expert on displays, but I had the Captivate for 2 years before getting the SG3. The Captivate has a Super AMOLED screen. Once I got settled in to the phone I generally never slid the screen away from the main home screen. I'm looking at it right now and I can't see any evidence of burn in.

Note 2 Screen serious problem

I have bought note 2 today but to my surprised its screen is so dissappointing even note 1 is much shiny and brighter and it looks like so much dull and dimmer
Really its the biggest mistake else I should have bought ip5 .

LOL I think the maps app is probably one of the smallest problems Apple has. That will get fixed... But it's iOS is SOOOO dated. It's camera is now taking purple pictures and Apple says "you're taking pictures the wrong way" ... Doesn't that remind of you Antenna gate anyone? The bezel of the i5 is SOOO fragile. TONS Of people are scratching their devices! I'd stay away from the iPhone 5! I had 4 iPhone 4 because of quality control and they kept breaking, and I just got rid of it and got an Android device. I've had the same Note 1 for almost a year now, and I have 0 issues! I'm getting a Note 2 as soon as it breaks the 580 euro mark here in Europe. Not long Amazon.de has it for 590

I brought this phone in india 2 days back. I too find the display brightness not very bright when i keep it in max brightness and turn off the Auto Mode. Then tested with Flashlight app keeping the screen in full brightness, My ZTE Blade turns much brighter and Note 2 is not that bright.
Took it to Samsung Showroom and compared with Demo Piece kept there. The Demo piece is slightly brighter than mine but still not near to ZTE Blade.
That apart, i find no issues in Resolution et all. That appears Crispy than Original Note, inspite of Note 2 being less resolution! Thanks to the new pixel arrangement!
Phonearena Review says this is the brightest of all Galaxy Phone and says it even excels in outdoor! Wondering what version they got!

People are ridiculous...a demo screen is not brighter, and the iPhone 5 does not have a better screen. This is a classic case of people seeing and believing what they want to see/believe.
If you want to go get an i5....then go get one...don't try to come here and say, "well the iPhone 5 is brighter" cuz that (in all fairness) is bull crap. It also has a smaller screen, and a much more expensive ecosystem. Not to mention the hardware/software problems experienced. If somewhere in your brain you feel more like a tech buff with an iPhone, then get it.
And sorry...but a demo screen will not be brighter...that is ridiculous. So, your assuming that Samsung intentionally made the demo screens brighter. Yea, and 9/11 was a government cover up by the Illuminati. If Samsung had the technology to make their demo screens brighter, it would also be included in the retail variant.
Stop spending so much time on tiny little specifications.

as i've written numerous times: it all depends on your personal "luck of the draw":
seen more then 10 different devices (note1, but will be the same for note2) side by side:
every screen had a different brightness and or tint and or blotches.
this is absolutely normal due to the manufacturing process (lithography, nowadays fine
metal mask and laser-usage which make this better, but not totally good)!
if you want to have a perfect screen you'll have to swap through a few devices!
>> if you are happy with your screen then DO NOT COMPARE!!!

Compare with note 1 side by side then all the stupids ill get the answer and yes I m not apple fanboy

I can confirm this. I compare my new Note 2 with Note 1, and my friend's S3. Note 2 is dimmer, it's strange cause in GSMARENA review, Note 2 should be brighter.
Besides, I found the screen is way over too much sharpness, dont know why. It's still a beast to me though.
Battery life is awesome, I can get 6h on screen, compare to my old Note 1 and One X 3h on screen max

[q] amoled burning

So like the title sugests i would like to know if its posible that the note 3 can get burning of the blue subpixels after several months of usage,i want to buy this phone but for me this is a very big drawback beacuse the screen is one of the most important aspects of a smarphone.
My 3 year old SGS has the screen still intact but i can se the pixel degradation but no significant burning just when i put the blue screen i can see a liiitle ghost of the notification bar but very very very dim almost unnoticeable,i have to mention i never used the phone with maximum brightness only in direct sunlight.
I have read some threads about this fact and it seems a general ill amongst the amoled screens so what is the chance i get burning on the note 3?
Thank you!

Of course can't exist experimental proofs because Note 3 just came out but if we look at s4, can be said that it has less problems in comparison with s3. As you know it depends on many things, even your way to use is relevant..but if your GS3 lasted 3 years (or more), I think that there is no reason why a note 3 should be worse, even because Samsung put BIG efforts on those relevant aspects for the customer

The same thing is with my Samsung galaxy S. But as this is 3 years old, it is still very little noticeable (mostly noticeable while white background). I am a big fan of Super AMOLED display of Samsung as it is attractive and looks awesome. I have used my galaxy S2 for more than 2 years and I find no such signs on it. Watch videos on Amoled display and LCD display and you will find a lot of noticeable difference in them, as amoled displays are sweet.
I think it's right choice to buy note3 as 2-3 years will be nice and then the slight change will be there which will be unnoticeable.
If you still are not in favour of note 3, consider buying nexus 5 as it's feature packed and will be the first to receive next android versions.

Pentile or RBG?

if it's Pentile, then S5 will be the first Galaxy S phone not to have any screen technology improvement over the previous model.

Does it really matter? I see this PenTile thing as pure whining, you'll never notice it in a 1080p screen unless you put your device under a microscope to use it.

Yes it does matter. And I am not whining because the screen technology has not improved after three devices.

So apply for a job at Samsung and teach them how to do it.
Seriously, S3 -> S4 was 720p to 1080p jump.
S4 -> S5 was the "screen now is brighter and can be very dim" jump.
I think you are complaining just because you were fool enough to believe the rumours.

Of course it will have technological improvements. The Note 3 was also "just" 1080p pentile and DisplayMate called it one of the best screens ever they tested, 600nits of brightness in auto mode under sunlight, improved color accuracy and more efficient operation. You bet the S5 screen is further improved, as well as SW modes to choose the most colorful or most accurate for your liking... this phone is only a disappointment if you judge by the looks, so far it's very promising all around.

If you guys missed it during the launch, s5 has brightest led screen ever made by Samsung @500 nits. Pentile vs rgb argument is a total bull**** for phones with full hd screens

It does have the brightest OLED screen, but LCD LED screens have been far brighter then that. The old LG Optimus Black from 2011 had a 700 nit screen and my Nexus 7 goes to almost 600 nits.
I saw a video of the Sony Z2 and Samsung S5 side by sidem and while the screen was definately brighter on the Samsung, it was also looked worse because the colors were too bright and washed out. I don't think OLED looks good when it's so bright.
But i can't be sure until i actually see it in person.

Its not pentile. Geex. I can't believe anybody has pointed out it is still diamond array RGBG. BIG improvement over pentile. Not going to lie though. Even though the RGBG looks fine and comparable to a standard RGB screen I wish it was at least like the galaxy note 2 or moto X screen. RBG with a bigger blue pixel. Looks awesome, can't tell it's not standard RGB stripe and it is efficient. I think the gnote2 and moto x so far have had the most efficient AMOLED screens so far.

It's PenTile.
The diamond is the arrangement, but it is still PenTile (just as LED HDTVs are still LCD with the LED simply describing the backlight). As you said, it's RGBG (another combo used by Moto was RGBW). RGB is the preferred subpixel layout. But seriously, the layout could be stripe, diamond, or it could be in the shape of a penis for all anyone cares, RGBG is PenTile.
