On the Verizon Nexus, I successfully flashed google wallet and fixed packages.xml so it does not force close when starting my phone or opening the program, but today I tried to pay at mcdonald's using my Nexus for the first time and google wallet force closed as it was saying 'sending'. Does anyone know why this might be or have any information? I didn't get to try again, there was a line and I felt like a tool so I just paid cash. I'll try again when I get the chance but wanted to ask around
[Nook Color Q&A, Help & Troubleshooting] jacobas92:
Okay, so the power button has worn out on my NC and I called and had a replacement order made.

The customer service rep I got spoke a very "broken" english. I barely understood what he was telling me. I had to repeat almost every bit of info I gave him. He even misspelled my name on the RMA ticket, even after I gave my name to him 5 times. :(

Now here's the question. What do I do now? I have the RMA number/ticket, which they sent to me in email. Will they provide me with a package to put my nook in? and if so, what all do I put in it? sorry for all the questions, but any help is appreciated as calling them back will probably only complicate things. And half the time you try to get a response from the email service, you get an automated response telling you to call them. If I can just go up to a barnes and noble store and have them replace it that would be great.

Like I said any help is appreciated, Thanks.
[Nook Color Q&A, Help & Troubleshooting] skeeterpro:
All RMAs I have done in the past, I packed up the unit and shipped via UPS (for tracking). Some manufacturers supply shipping labels but it sounds as if you were not issued one. To avoid possible complications, I have always taken pictures of the packing process (with time/date stamps) to document that the unit was in good cosmetic shape to refute any claims of CID (Customer Induced Damage) or shipper misconduct. I attached a statement reflecting that to the RMA documents included in the box. Try always use original boxes and packing items packed in a separate shipping box. (UPS can do this for you for a nominal fee). Depending on the problems, sometimes any accessories (power supplies, USB cords, etc) can be left out as those sometimes get "lost". Always make sure you have flashed back to stock. If Support sees a rooted unit they can refuse to do anything as rooting voids most warranties.

Hope this helps!
[Nook Color Q&A, Help & Troubleshooting] votinh:
Well said, skeeterpro.

To OP, if they don't hand you the box, meaning you have to pack it up yourself.

If they don't send you the shipping label, meaning you have to pay shipping fee (if they reimburse, great, if not, it's out of your pocket)

Some vendors require very specific RMA package must be sent through a certain carrier, if not indicated, I would go with USPS for cheaper price, do make sure getting the delivery confirmation (and/or) signature required.
[Nook Color Q&A, Help & Troubleshooting] jacobas92:
Thank you so much for the replies, guys. I ended up taking it to the b&n and the Guy at the counter just gave me a brand new one. Problem solved!

Well.........that's works, too! :)

Good for you, dude.

Lucky you didn't get a refurb, I had 3 arrive DOA. I'm shipping them all back tomorrow (I'm sure the shipping will be $20-30). Still came out ahead at $120 each for 9. Still, that's a horrible failure rate for supposedly factory refurbished device.
[Samsung Galaxy Nexus] PrawnPoBoy:
Previous to my GN, I've had a Nexus One, Nexus S, and Galaxy S II (international version) and on all of the phones black levels were pitch black and no different to the screen being completely off. Despite still being an AMOLED display, it seems the GN's screen can't do pitch black.

As a test, go in a dark room and open the clock app. Long press anywhere on the screen and the clock will go into night mode where it will be a completely black screen with just the time showing. You'll notice that there is a still a bit of light emitting from the dark spots.

A little disappointing... I wonder if this could be fixed in software.
[Samsung Galaxy Nexus] player911:
It can do pure black but not everything is pure black. I just rebooted and say the Google boot image. Its solid black. I'm in a dark room now and can't tell a difference where the soft keys end and the case begins.

Actually that's just the clock app, you can easily see that it's an extremely dimmed version of your wallpaper. My wallpaper is this http://cooldesktopbackgroundsx.com/wp-content/uploads/2011/02/34327523.png

and I can easily see the eye in the dark mode.
[Samsung Galaxy Nexus] PrawnPoBoy:
I don't see how your background could make a difference. Night mode is completely black. Just look at the screen shot.

I can also notice this when first booting up and see the Google logo. It was the same this on two other units that I looked at, so I don't think it's unique to my phone. To truly notice it you have to be in a pitch black room. I only noticed it because I was using my phone as a bed side clock.
[Samsung Galaxy Nexus] tryceo:
No screen will give you true black that close... Maybe you need a plasma tv screen

[Samsung Galaxy Nexus] PrawnPoBoy:
The whole point of AMOLED is that each pixel is it's own light source which can be completely turned off. True black was possible on every AMOLED phone I've ever used prior to this one.
[Samsung Galaxy Nexus] jetrii:
That is exactly correct. Fortunately, at very low brightness, my GN does indeed display true black. I have an all black background and if I cover the time, I can't tell a difference between the phone off and on. Keep in mind that true black only occurs under extremely low brightness. Turning the brightness up introduces a bit of light polution.
[Samsung Galaxy Nexus] Zacisblack:
No, no... I've owned the Fascinate on Verizon and when in complete darkness you can see a little bit of light emitting from the screen. The Gnex just has more pixels so there's probably more light emitting. But the blacks don't seem to be any less black than my Fascinate. When you turn the screen on the pixels must be excited in order to know when they must turn on or off, this will still emit a miniscule amount light.
[Samsung Galaxy Nexus] Protonus:
I'm sorry but you're TERRIBLY mistaken and I wish this thread would get deleted before you confuse others! Night mode is simply DIMMED. It is NOT 100% black, but transparently darkened. There is a really easy way you can see this for yourself, simply turn on an animated live wall paper and go into night mode in the clock. You'll se the moving live wallpaper in the background in the "black" areas. That screen shot you took is showing the TRANSPARENCY where it's black. It is NOT actually black there!!!

The GNEX screen is JUST as black as any other SAMOLED Screen if not even more so! If you want to see 100% black - just boot into clockwork mod recovery! the entire background ther is 100% black and you'll see how inky black it looks! That said the status bar at the top of the screen is also black, and blends right in with the bezel.

when i dim my clock app i can still easily see my background live wallpaper...

[Samsung Galaxy Nexus] PrawnPoBoy:
What are you smoking? Download that screen shot and check thd color yourself. Its #000000, meaning BLACK. The only confusion is with people not knowing how to go into that mode in the clock. LONG PRESS, not just a simple tap.
[Samsung Galaxy Nexus] PrawnPoBoy:
Managed to finally find another thread talking about this. Theres even photographic evidence using a long exposure shot.

I guess the comment that there is always a minimum amount of power in even the black pixels could be accurate.
[Samsung Galaxy Nexus] devadvance:
Yes. From what I have read (OLED information, a few book selections, and an interesting patent) sAMOLED displays include what is called "pixel pre-charging".

This is due to the fact that it is far easier to precisely control the pixel, which corresponds to a "drive voltage", when the starting point is a pre-charge. Its faster and more accurate. However the pre-charge causes light to be emitted. There is no avoiding that. As much as people say "my nexus s/galaxy s/galaxy s 2 have pure black", there is NO SUCH THING even on a sAMOLED display. Contrast ratio for the Galaxy Nexus is 100,000:1 rather than infinite.
[Samsung Galaxy Nexus] Godo_PPL:
Hi, just wanted to put this topic to rest.

Was somewhat disappointed in the screen performance of the Galaxy Nexus, coming from an Galaxy S2. However I reckon it is an issue that can be fixed with drivers.

The blacks on the Galaxy Nexus are far from as good as the SAMOLED+ panel on the SGS2.

Here are some pictures of them side by side with the clock app set to night modus.

Not a deal breaker for me, but I hope this is improved in future updates.

PS: Sorry for the big-ass pictures..
[Samsung Galaxy Nexus] pr3cision:
my screen is blacker than the bezel..
[Samsung Galaxy Nexus] cancerouspete:
What is your wallpaper, cause I think I can see it in the second to last photo. Like stated above, the clock is only a semi transparency over the wallpaper. Run a screen checker and take pictures of that black, that would be a better test and example

Edit: in all likely hood its just a calibration issue. Franco's kernel improved whites and colors significantly over stock. Personally, I can see that its not 100% black at the moment, but it is 99.999% black. And 100x better than backlit

[Samsung Galaxy Nexus] kindiboy:
The technology switches off the pixel so there is no blacker than that if you are not getting pure black then something is wrong most probably the wallpaper is not really black.
[Samsung Galaxy Nexus] cypherx82:
The dimmed clock isn't even close to true black.
[Samsung Galaxy Nexus] Hot_Hands:
Well OLED displays pre charge the pixels as stated earlier so my theory is that the galaxy nexus gets a little glow compared to the older screens because of the sheer number of extra pixels being pre charged. We're talking 500k more vs a 480x800 screen.

[Samsung Galaxy Nexus] Protonus:
I agree with this. Since I said before that the Gnex screen is 100% black, i have now seen the "issue" this thread discusses. It wasn't until I used my phone though, in 100% darkness that I saw it. And you have to look at the bezel to compare. Here's the thing, it's still incredibly black. Only by using it in a completely darkened room can I see any precharge or glow. Yes, that amount of glow IS more than i saw on my Fascinate, but as the quoted post points out, the Gnex has WAY more pixels, so this make sense.

I think it's an incredibly moot point though. Whenever you're looking at a display, black's will look as black as whatever you have to compare them too. That's why you surround a projection screen with a black velvet border, so your eyes will see that black and try and relate them to the projected image as a point of reference. When using the phone with normal lighting, the display looks even blacker than the bezel of the phone - and I think that they intentionally made the bezel sort of brown for this sort of reason.

This display is still has WAYYY more contrast and higher black levels than any LCD, so I'm still very happy with it. Would it be even better if the pixels didn't pre-charge, or if they put a tint on the screen to hide some of the precharge (at a cost of brightness)? Maybe? I'd rather they used a standard rgb pixel arrangement than pentile too. But I'm still very happy with this display. There will always be ways you can "make something better".

was the galaxy s screen glued to the glass or separate? galaxy nexus is glued together. does this make a difference?

[Samsung Galaxy Nexus] hol17:
That's because you have to hold your finger on the screen instead of tapping it to get the black background (the time will turn cyan).

Next time, don't be silly.
[Samsung Galaxy Nexus] pr3cision:
R we talking about wankstas or Oreos? Quite racist.
[Samsung Galaxy Nexus] reuthermonkey:
Except that this has nothing to do with perception.

Fact 1: AMOLED screens do not power pixels that are intended to be #000000

Fact 2: The clock "night" mode is NOT	#000000

Fact 3: OP doesn't know what he's talking about, or is a troll.
[Samsung Galaxy Nexus] draugaz:
It is far from a "fact", it is just a silly marketing statement. The reality is much more complicated, common AMOLED circuits are forced to keep pixels powered on all the time just to avoid transitional problems.
[Samsung Galaxy Nexus] dawynkoop:
I believe the OP is correct about the night mode. If you open the clock app you get the clock over your current background (Desk clock mode), tap it once and your background dims as well as the clock ("Night" mode), from there if you tap and hold a couple of seconds the background will go completely black and the clock will turn blue (I belive this is the mode the OP is talking about). If I look at the phone in that mode it seems as black as the rest of the phone, but I don't have a truly dark room to test in for sure.
[Samsung Galaxy Nexus] mutelight:
The blacks are deeper than my plasma by a long shot and it is a fairly high end set. AMOLED doesn't have the color accuracy and my plasma is very bright but for for a phone screen I love the tech on my GN and SGS2. :cool:
[Samsung Galaxy Nexus] RogerPodacter:
this thead is interesting, i tested in a dark room last night and i too see that the screen is not quite as "black" as my n1 used to be. i'm trying to rack my brain why this screen would be different since both are amoled technology. perhaps it is the 3 on screen keys reflecting ever so slightly. i'm at a loss what else it could be. maybe the higher pixel density is causing it...but why would that make any difference?
[Samsung Galaxy Nexus] k_myk:
Built in alarm clock has two night modes:

1) Hold your finger on the screen. Background turns IMHO black and clock is cyan.

2) Tap the screen. Alarm clock dims. Then hold your finger to get, again, IMHO black background and darker clock.

I think described above background is black, because you can see the same effect in gallery and for half of second during "CRT off" animation.

So which night mode we are, actually, talking about? :p
[Samsung Galaxy Nexus] polo045:
Here's a true black for whoever is complaining about a true black screen on this awesome phone! Just something to complain about. Really though?! You got a job? You got time to nitpick the **** out of the best phone on the planet? Instead of just enjoying it?

Wow I got through the first page of this thread before wondering how people can get aggravated over stupid crap like this, then have other people come and join in on the pointless debate. OP, eBay the phone if you really want to piss your pants over the lack of blackness in the pitch-black pixels.
[Samsung Galaxy Nexus] derrelicte:
My Nexus One (AMOLED, definitely not the SLCD version) has a very dim black when I'm on clock mode, too. This isn't exclusive to the GNex by a long shot.
[Samsung Galaxy Nexus] sheik124:
You're not entering the night mode properly. Long press. In pitch black darkness, my N1 is also pitch black.
[Samsung Galaxy Nexus] GinoSylum:
For any moron who doesn't like the phone because of the black thing, you're right... It's junk. Send it to me and I'll give it to my girlfriend so her and i can both have these horrific phones. I'll even send you 2 used incredibles for your time...
[Samsung Galaxy Nexus] ikediggety:
Enough with the alarm clock.

For a real black test, download "dead pixel detect" from the market. Start it and tap the screen until you get to the black one. this way you know that the pixels are completely off.

Now turn off every light in the room.

And yes, there is some glow there. I always had a little bit on my old dinc as well.

That said, I think we're all in agreement that SAMOLED is the best phone screen tech that exists right now. :cool:
[Samsung Galaxy Nexus] derrelicte:
No, I definitely am. I do it every night in my desktop dock since my N1 doubles as my clock.

That's what you get when you (i mean vendor) hype certain things as an ultraimportant-must-have-killer-feature. So, everybody goes in to their closets to scrutinize their devices in this regard.

Now as it emerges, their own products do not stand up to their own hype. OMG, the world is just collapsed. Therefore the reaction.
[Samsung Galaxy Nexus] RogerPodacter:
why do many people jump all over everyone. i think the point of this thread is that it's fun and interesting to figure out the technical reason behind this behavior. it's not people crying that they hate it. it's all about curiosity.
[Samsung Galaxy Nexus] Godo_PPL:
I would love to know if there was a software update that could correct this. Not really a big deal, I love my galaxy nexus anyways!

It does really seem that the phone is incapable of showing true blacks, like my galaxy s2 did, and given the "almost" same technology behind it, it truly is a puzzle..

If you open my pictures (post #17) in an new tab it's easier to see the difference between SGSII & Gal-Nex)

Just to clarify, the shots where the clock has an blue-purple color, is the "night mode" (aka. long-press)

If anyone has seen any progress on this issue, let me know!
[Samsung Galaxy Nexus] volsey:
Just a heads up, the Nexus One doesn't show complete blacks on the night mode of the clock app. I'm running completely stock 2.3.6 and have noticed this for a long time btw. I don't know if this is just the app, or the actual screen, and really it doesn't matter.

As for it not showing complete blacks, good thing the human eye works relatively to it's surroundings (ie. Contrast). If there's even a hint of color or white on the screen you are not going to be able to tell that the black levels are not 0.000000 cd/m2.

You're knitpicking, and the fact is Amoled black level is still <<<<<<<<<<<<<<<< than that of any IPS or Super Duper LCD display PERIOD
[Samsung Galaxy Nexus] RogerPodacter:
this is truly a mystery to me what the technical reasons are for this behavior. The clock app isnt the best way to see this issue. Instead use the app lcd test or dead pixel detect and go to color black. The only thing i can think is that the nexus one and galaxy s2 did in fact.slightly light black pixels as well. But the lower resolution made more space between pixels so it looked dead black. And with these new high res amoled more light is visible. Cause the galaxy note forum has this same topic question, so they suffer this issue too.
[Samsung Galaxy Nexus] @rbiter:
You did mean > > > > > > > > > > > right? Lol. Cuz you just said less than that of lcd and that is just plain wrong.

How about we add to the discussion, whites that dont look pure white?

Im wondering if there are 2 "sets" of screens going around.........some people are complaining that blacks arent truly black. Some people are complaining whites arent truly white.

My phone is completely black when looking at an all black screen (I do already test with dead pixel tester). BUT, white is "warm"....slightly orange/yellowish.

If I use Screen Adjuster to tune the warmth out, black becomes not purely black. That leads me to wonder if phones that arent truly black all have perfect whites. Yet phones that are truly black have slightly warm whites.

I checked a demo GNex at a Verizon store and sure enough, the screen looked "warm". Even had worse signal strength than my phone literally 1/2" away from it. It DID, however, display less of the vertical banding issue than Im seeing on my phone. I might try to get another from WireFly to compare to mine.

[CONFIRMED] Full-screen black; pixels stay lit!

I apologize for the large images, but I'm sure you guys' internet can handle it(:

So out of my own curiosity, I decidedto do my own expirement.

I used a Sony Alpha NEX-5 with a Canon FD 55mm (75 crop) @ f/1.8

Started with ISO 800 with 30 second shutter, here's what that looks like:​

ISO 800; 8-second shutter:​

Next up, ISO 200 with a 2-second shutter (before you say you see nothing, take a closer look....) :​

ISO 200 with 30-second shutter:​

different white balance ​

Those dark spots aren't dust or anything. Idk wtf that's all about o_O Kinda looks like sunspots lol

Now I just decided to get silly and believe it or not (I can provide a RAW image file if you PM me nicely about this one) but this is what it looked like at ISO 12,800 with 30-second shutter speed:​

Less as in lower measured light output. Lower number means deeper blacks, 0 means zero light output, infinite black etc.

Not lesser as in lesser quality...
