Lit black screen - Samsung Galaxy Nexus

Hey guys, question. On a black scree , I noticed the screen is not pure black, it has some light. Only noticeable in dark rooms, even if the screen is on minimum brightness.

That's normal. The device is designed as such to reduce transition time

I'm guessing there's no way to make it completely black?

I used to have a SGS2 and I really liked the blacks, without that light (at least not as noticeable)
Is there any difference? Battery or something?

Anything????? I can't be the only one that wants this

Amoled already shows black as 'more black' than tft displays. Currently no tft/oled technique exists that will display black as actual black (like when the screen is off) afaik.
Having said that, I really like the black on my gnex. Dark enough for me.

Different colored Gradients?

I've noticed my device has a different colored gradient than on most others I've seen on here.
For example:
In settings and after enabling hw acceleration in certain apps such as the xda app.You can see an obvious difference when compared to the settings menu on this video. http://www.youtube.com/watch?v=E2g_QhlvmaY&feature=youtube_gdata_player

Well apparently my screen looks like an LCD screen. None of the colors pop and the blues look grey. I've noticed the galaxy nexus phones that have the gorgeous display have the blue gradient and a darker non cyan blue for wifi and cell bars as well as the dialer. If your phone has the grey gradient and the wifi is cyan from stock. I suggest you take a closer look at your display.

I'm not really seeing the issue here. The gradient is supposed to be grey, not blue. The fact however is that the GN screen has problems with accurate color reproduction and the samples that you linked seem to have a lot of blue/purple color noise.

So what you're telling me is I'm one of the lucky few to get a good GN? Because before purchasing this phone I saw many video reviews for it and all of them had that blue gradient...not a gradient like the picture above you but still blue.

Maybe a Black Wallpaper would improve battery life?

Oh. My. Gosh. Genius!

In super amoled light background doesn't really affect the battery.
Other than your really conscious about the battery life i suggest turning off the LV wallpaper and replacing it with black.

Actually it's been proven otherwise back in November.
Black vs White background at different brightness levels:

Look forward to you comparison!
Don't surrender to colors!
Amoled works almost the same as plasma. Each pixel illuminates.

And brighter images use more power. Sucks manufacturers are limiting power consumption on plasmas by reducing power on bright images.

Umm yeah, welcome to 2009. We all know black colors use less power than white on amoled screens.

^seriously.
Also, who spends so much time looking at their wallpaper (especially a boring, solid color) to notice any difference?
I put black wallpaper I got those ugly black spots in the screen. blah
I used to use a black wallpaper because hey, why not, save on the battery, right?
Then I thought about how often my phone is actually displaying my wallpaper and decided it's a trivial matter. It's only ever a few seconds before I tap on something on my homescreen and it goes away. If I was constantly reading info off of widgets, at length, I'd care about it more.
These days I just load up whatever picture I think I'd like to see every now and then. Although I did like the clear contrast of pure black vs the icons etc.
Edit: Also the test linked to in one of the first replies, worth noting that Minimum brightness, white image is only slightly worse than the black results. Brightness matters more than color. Dial it down and look at whatever colors you like best.
Pssst...download no wallpaper app from market. Its a true no wallpaper display.

I've never used anything other than black on any mobile I've ever used.
I use a solid black wallpaper, but not to save battery. I just like the way it looks.

For me black wallpaper does matter coz if i open my phone its like 2 seconds before i launch and app leaving the home screen. ^o^

I suggest you themes with inverted apps like mine if you really wanna save something, a wallpaper does not saves that much

Doesn't this happen due to a low res not pure black image being used?
I never had that issue, so unless something is wrong with your display I suggest trying a different image

Wallpaper issue

Is it using bright color wallpaper like white will use up lots of battery as it is amoled screen?

Depends on brightness.

Total black background will use the least battery since amoled doesn't use any power displaying black pixels (pixels are turned off).
Swype'ed on my CM10 Galaxy Nexus

|Q| Quick Question..

Because of the amoled screen the GNex has which of these would save more battery,
a white background with brightness at 0% (dimmed),
Or
a black background with brightness at 100%(full)?
I know dark backgrounds save more battery just always wondered about screen brightness.

I remember someone doing an experiment on that. Black with full brightness lasted longer

I am not the expert but I am guessing , the brightness has nothing to do with the pixels shown. It is just makes them dimmer or brighter. So whether it is black or white pixel it will make it brighter .
Hence I think irrespective of the color pixel it will still consume battery if you have black or white pixel

I think this is what you are looking for

black pixel lits up

Hello, the question is when you use a black wallpaper on the s3 the pixel don't lit up right ? so I downloaded a black wallpaper and tested it out. I noticed all the pixels are on,but it is not pure black(like when you lock the phone). I have tried 3-4 types of black wallpaper but none on them seem to work
I have tried it on stock Note 2 but it is the same. I tired using paint but no luck.

True black does not light up the pixels. I used Paint on Windows 7 and created a black wallpaper. As for the lockscreen, if you have the ripple effect on, it will not be true black as it is part of the effects. Turn it off and you will see the difference.
