A big concern with AMOLED comes with if you plan on keeping your device for longer than a year.

The organic element can start experiencing degradation in as little as 1000 hours. The colors degrade in the order of Blue, Green, and then Red. This results in color shifts that make everything look off.

You pick up an AMOLED device that is two years old and sometimes it looks very pink, or green. That's because of element degradation.

Not a big deal if your phones are out the door every 10-14 months, but you're not keeping a 3 year old AMOLED device and still having a good screen.

That's outdated info from 2008 from Wikipedia that applies to general OLED and not Samsung AMOLED and with the false assumption that no progress has been made in the last six years. From ownership experience of 2010 Galaxy S1 with AMOLED display that still looks fine I'm not worried about FUD from people who don't even own AMOLED.

http://en.wikipedia.org/wiki/OLED#Disadvantages
The biggest technical problem for OLEDs was the limited lifetime of the organic materials. One 2008 technical report on an OLED TV panel found that "After 1,000 hours the blue luminance degraded by 12%, the red by 7% and the green by 8%."[66] In particular, blue OLEDs historically have had a lifetime of around 14,000 hours to half original brightness (five years at 8 hours a day) when used for flat-panel displays. This is lower than the typical lifetime of LCD, LED or PDP technology. Each currently is rated for about 25,000–40,000 hours to half brightness, depending on manufacturer and model.[67][68] Degradation occurs because of the accumulation of nonradiative recombination centers and luminescence quenchers in the emissive zone. It is said that the chemical breakdown in the semiconductors occurs in four steps: 1) recombination of charge carriers through the absorption of UV light, 2) hemolytic dissociation, 3) subsequent radical addition reactions that form π radicals, and 4) disproportionation between two radicals resulting in hydrogen-atom transfer reactions.[69] However, some manufacturers' displays aim to increase the lifespan of OLED displays, pushing their expected life past that of LCD displays by improving light outcoupling, thus achieving the same brightness at a lower drive current.[70][71] In 2007, experimental OLEDs were created which can sustain 400 cd/m2 of luminance for over 198,000 hours for green OLEDs and 62,000 hours for blue OLEDs.

Notice you linked to OLED and not Active-matrix OLEDs (AMOLED) which require a film transistor backplane to switch each individual pixel on or off, and allow for higher resolutions.

http://en.wikipedia.org/wiki/AMOLED

AMOLED displays may be difficult to view in direct sunlight compared with LCDs because of their reduced maximum brightness.[11] Samsung's Super AMOLED technology addresses this issue by reducing the size of gaps between layers of the screen.[12][13] Additionally, PenTile technology is often used to allow for a higher resolution display while requiring fewer subpixels than would otherwise be needed, often resulting in a display less sharp and more grainy compared with a non-pentile display with the same resolution.

The organic materials used in AMOLED displays are very prone to degradation over a relatively short period of time, resulting in color shifts as one color fades faster than another, image persistence, or burn-in.[14][15]

And when did the S1 RBGB-Matrix (Pentile) 800×480, 233 ppi displays ever look "fine." They looked like crap even then. And don't even bother stepping outside and try using the device when the sun is up.

AMOLED displays weren't worth a damn until the S4.

And I've owned 5 AMOLED based phones so spare us the faux high road.

That's my point. You mentioned AMOLED but quoted FUD data from regular OLED TV from 2008. In the end, the iPhone 6+ colors are off out of the box while regular OLED is good for five years per Wikipedia so improved SAMOLED is >5 years which is way beyond the typical upgrade cycle. Nice try though and enjoy the color inaccuracy, backlight bleed, yellowing, book spining, bad pixels, etc. of LCD.

Agreed. Not sure why some people worry this and worry that until they can't enjoy the device. We hear a lot of this here among the apple fans..

...worry about resale value
...worry about oled burn in that may never happen and instead opt for cheap inferior lcd with lousy color and contrast and uneven and yellow patches
...sing praises about the design of the scratch prone aluminium can iphone but hides it with ugly looking case.

My S5 has an AMOLED display last time I checked :rolleyes:

You mentioned you were getting an iPhone 6+. Maybe it's good you have to wait for supply so Apple can attempt to fix some of those and other out of the box issues.

I kind of disagree. I held an iphone 6 plus and a note 4 side by side and compared it. The 6 plus display looked noticeably brigter AND white is just so much cleaner on the LCD compared to the tinted Note 4 Display.

I completely agree. In fact the the iPhone is 30% brighter than note 4.

Not if the note 4 is in auto bright mode. Its the first phone I can clearly see with my convertible top down. 750 nits for the note 4 versus 500 for the ip6, a significant difference. I also hate how you can't see iPhones displays with polarized sunglasses.

One that is an If and two that is a peak number that isn't sustainable for more than a minute or even seconds, Lol just like when Samsung was overclocking their CPUs to give their phones better benchmarking results.

The note 4 has 424* nits vs the iPhone 6 plus at 566* nits.

*displaymates results

Phones arena said the iPhone 6 plus's display was 30% brighter than the Galaxy note 4s.

Here is a screen shot.

Nobody would use it at max (manual) brightness under normal conditions so that's irrelevant. Note4 can turn to extreme brightness when required is much more useful.

And I can bet lcd screen at 566nits would be very washed out as black would look like gray. But amoled will still retains its brilliant contrast which effectively makes image looks brighter and clearer.

I think you and that review site are sorely mistaken. Put the Note in auto brightness mode and it will amp up to much higher levels when needed. Even my Note 3 does this and outside it works beautifully.

But hey, Apple is more profitable so you guys always have that going for you :rolleyes:

Well you would lose that bet.
But that's not a very big surprise since you obviously have no experience with the 6 plus.

So now the review site is wrong. Lol.

Displaymate is wrong, ok.

You Samsung haters are grasping to try and find anything to put down the new amoled screens from samsung.

Here is where my brightness is 90% of the time

I used to do the same on my note 4, to conserve battery life,

Note 4 750nits isn't an if, not sure what you mean. It works beautifully with my convertible top down and the sun shining directly on the screen, simply amazing and the first phone I've ever seen that allows me to see it like that. I also got the 750nit spec from displaymate. Put them both in direct sunlight, I'll bet you anything the iPhone's screen will be unusable. Other than direct sunlight and even using manual max brightness I've highly doubt you will encounter a situation where the manually better brightness on the ip6 helps in screen viewability, sorry I'll take sunlight viewability any day of the week, ie: Note 4 750nits versus iPhone 566nits.

Edit: the linked image illustrates just how utterly stupid the argument is, they look virtually the same to me. Now put the note 4 in auto brightness mode and put them both in direct sunlight and lets see the difference. Also probably not a plus for the majority, but I can't see my iPhones screen with polarized sunglasses, that's a major negative for me outdoors as polarized sunglasses are highly superior to non-polarized sunglasses.

The bolded is false. I have polarized sunglasses and can read the iphones' display without a problem.

No there is no need too.its to bright 90 percent of the time and when I'm out for a run etc auto mode works great and even max brightness will do most times.

Stop spreading bs lies you don't have a note 4 or never had one.

Samsung never over clocked its cpus either stop spreading bull ****

Then ran at advertised clocks.please post up where they over clocked the cores and I will PayPal you 20 bucks

Ps I laughed out loud when I read to save battery life lol I get an easily 2 days of power using the phone staying on 4G lte and not even using wifi.

Yeah I run the screen that way to save power lmfao
