I am still very intrigue about Super Amoled Plus displays because I have a SG SII.

Is it true that the most sure way to see if you phone without looking at the specifications, have Super Amoled plus is by putting on a completely black wall paper?

I heard that Super Amoled Plus screens don't show any light in the black colors.

amoled phones have over saturated colors, especially blue, as blue color fades through time on display - that is easiest way to see it IMO.

Correction ... must AMOLED/SAMOLED/SAMOLED+ displays are run overly saturated -- the problem isn't the display but the way it's setup to be used. Check out the Samsung Galaxy Nexus and you see they run more neutral with that device.

And no one has answered the original question :p Yes the blacks are true blacks. LCD's block the backlight to create black where is a AMOLED screen just does not create the light in the first place for black.

Yeah, it's pretty amazing the difference when I compare my Galaxy Nexus to my TouchPad and Droid 1.

Yep, that's how I do it. As a matter of fact, my wallpaper is just a blank black wallpaper now.

they last, just colors will start fading eventually, that is why they are over saturated in first place.

Dang I like my crisp colors on my SG SII> :(

what is the average lifespan of the amoled screens? I mean until the fades become noticable.

This is from wikipedia:

Lifespan: The biggest technical problem for OLEDs was the limited lifetime of the organic materials.[55] 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 rated for about 60,000 hours to half brightness, depending on manufacturer and model. 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.[56][57] 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.[58]

I am guessing super amoled plus can last over 5 years with 8 hours a day used

The black pixels in an oled are actually pixels turned off, so it's a true black. It also used less power too. On the flip side, white pixels use more power than the conventional LCD.

Yep, there's a reason why the UIs for Windows Phone and Android are more on the darker shade compared to iOS, the use of AMOLED screens in flagship devices like the Galaxy Nexus and Lumia 900.

AMOLED screens suck, IMHO. The colors are off and the whites are not as bright as LCDs. I definitely prefer LCDs (Sharp's LCDs are the best) to OLED/SAMOLED...

Well that's your preference. My phone is always on the lowest brightness lol. I'm a student and I want my phone to last. That's why my gnex is rooted and undervolted

This was done early last year but a website did a test of screen color quality and the only mobile screens that were the most accurate were from Motorola. Apple's screens undersaturated as much as Samsung's AMOLED oversaturated.

People keep repeating that same 2 year old review.
The screen on the original Droid and Droid X is not the same as what's on the Atrix, Droid X2, Droid 3, Bionic, and "other"(I haven't compared any of Moto's phone after the Bionic) Motorola phones today.
It would be foolish for anyone to compare the screens from phones Moto made 2 years ago and assume that they're the best today.

That review was done before Moto changed to crappy pentile, checkered board screens.

More importantly, Motorola doesn't manufacturer screens. Samsung is purposefully going for a saturated look on its phone displays.

I love my SGS2 screen. The black levels are truly impressive and shows how bad my old Atrix screen really was.
