What production run is your tablet from? (Look at SSN) Is it defective? - Nexus 7 Q&A, Help & Troubleshooting

On the box, there is an "SSN" number. Supposedly, if you have an SSN that starts with C70k (or better yet, C80k), it will not be defective. However, all of the tablets I've had (4) have started with C60k, which is the very first production run. They were all defective .
So if you have a nexus 7 tablet, and kept the box, please check it out so we can try to find which production run has perfect Nexus 7's!
I'm not sure if posting your entire SSN is a security issue, so I would advise you to just post the first 4 letters and numbers.

I have a C70K but it hasn't been opened yet. The one that has is a C60K I bought two weeks prior to receiving the C70K. My C60K has very slight screen lift on the middle left-side, but is good otherwise. Just waiting for my plastic case opener to come in so I can fix the screen lift.

There are perfect C60's (like mine), and defective C80's. This has been discussed ad nauseum.

Mine is a C60K. Only issue is minor screen lift on the left side, not enough to be a issue for me.

1st on was a C60K, it had very apparent screen lift and a squishiness on the left side. New one is a C70k, so far so good...

I have a C60 and it is perfect. No screen lift, perfect display... it's perfect.

All of mine have been from Gamestop:
1st C6 - would turn off at 20% "show low low battery logo" even after calibrating bad battery? Perfect screen, exchanged
2nd C7 - bad left side screen separation/lift, exchanged
3rd C7 - dust under the screen, 2 spots , exchanged
4th C7 - minor left side screen seperation/lift, just started doing the death at 20% exactly like the first C6 I had for no reason today, exchanged
5th C8 - minor left side screen seperation/lift , missing two screws under battery cover (left side of screen) , returned for gift card

C60K has minor screen lift and faulty speakers, but otherwise good.
C70K has uneven white pixels. Left side of display is clearly brighter than the grey/orangish right side. Seems perfect otherwise.
Both are getting returned.

I have no idea where you're getting that. There's absolutely no evidence to support the notion that any serial number prefix is more or less problematic than any other. Also, I'm not aware of anyone actually receiving a C80 unit yet.
As a refresher, ASUS uses a certain code to date their products. C = 2012, 7 = July, so a C70 prefix merely means a unit was built in July. A C80 prefix means it was built in August. That's it. Even the assumption that devices that are made later will be better built is suspect, because that presumes that fixes have actually been implement in manufacturing.
However, before a fix can be implemented in manufacturing, it has to be designed, then tested, and then new parts produced, and then test manufacturing runs performed, and changes made to the manufacturing process. I'm probably missing some steps as well.
Once the new build is approved, it could go into production at any time, including during the month. So, a C80, or C90, or whatever, that's produced before the new build goes into production, will be the same as C60, or C70, or whatever units. C80, or C90, or whatever units that are produced AFTER the new build goes into production won't have the problem.
This whole "if you have a CX0 unit you won't have problems" meme needs to just die already.

First was a C60K. It was "perfect", but I returned it because I thought the washed out colors and video playback issues were defects.
Second was a C60K. It had raised glass on the left side (couldn't push it down, something forced it up). I returned it.
Third is a C70K (and what I'm still using). It has lifted glass on the left side. I was able to push it down, clamped it over night and it stayed down a week. Now it's lifting again. I may return it eventually, but waiting a bit longer to make sure the manufacturing issues are mostly resolved.
Fourth Nexus 7 was a C60K I picked up from Staples. It was "perfect", I was thinking about getting a refund on my third Nexus 7 16GB and switching to this 8GB model. But ended up changing my mind, so returned it.

That sounds like you are talking about a hardware revision. The hardware for the most part seems okay. The problem is the the manufacturing process seems to not be perfect and quite a few defects are slipping through. The hardware doesn't need to be redesigned, their process needs to be fine tuned.
And to me it's reasonable to believe that the manufacturing process could have gone through some refinements between the C60K batch and the C70K batch and more in the C80K batch. A perfect C80K is no better than a perfect C60K, but hopefully the chances of getting a defect are going down as they fix whatever was going on in the process that caused these defects.

Have a C70k unit, everything was perfect (I think) but recently noticed that my speakers have blown (very distorted sound). Waiting for my replacemrntunit before I send this back.

c70k 16 Gb reporting in as perfect!

Waiting for C90K production runs hopefully with the newer Hydis color corrected 1280x800 IPS Displays or SHARP 1280x800 IPS Displays. Really cant get past the Pastel greens, and slightly purple blue colors. And thats on a good display some people are living with Yellow tint screens or blue tints. Its the one main thing of a tablet, GET THE DISPLAY RIGHT.

My C60 is perfect. No screen lift, no dead pixels, good sound, etc. etc. etc.
All we have us anecdotes...nothing to base anything on. This board is not a good sample.

c60 so far so good

C60K here. The Nexus7 that I have is perfect. No problems or defects at all.

Manufacturing Imperfections (Sketchy Build Quality)

Alright, so right off the bat I just want to say that this isn't a doom and gloom thread (I hope), but it's an issue I wanted to ask you guys about since I'm on my 2nd phone now and I've had cosmetic issues with both. I want to love my phone, I just want one that won't give me problems first! I will post pictures soon, to show you guys what I'm about to describe below.
Both phones have had minor (but very annoying) imperfections involving the casing. My first phone was the most problematic. First off, the battery cover did not sit flush. I did not realize how much of a difference this made in terms of build quality until I got my second phone. My 1rst phone would creak and click when pressure was applied to the back and it just did not seem like a very sturdy device. This was not the case with the second phone (which had a back cover that fit perfectly) as there was no creaking or clicking, it felt rock solid just like its supposed to. Also, there was a small chip and discolouration of the teflon coating on the bottom left front face of the first phone. Again, nothing major but still not something that I was not pleased about given the price of the phone.
Unrelated but my first phone also had the purple tint issue which is the main reason I returned it and bought a new one (I couldn't outright swap because I don't live in the US). My second phone came in and luckily it did not have the tint issue. All I can say is WOW, what a difference it makes having a proper screen!! The black colours actually look crisp and dark, and there is absolutely no tint at low brightness.
So the screen was good. I checked the bottom left hand to see for any issues with the teflon, and there were none. I checked the backplate and like I mentioned earlier, it was perfectly flush. So far so good BUT.. again there were some cosmetic issues! Along the left side of the phone there was a tiny chip and some of the grey finish was off. Also, on the back, the bottom teflon piece did not sit flush with the rest of the device.
Once again, these are minor yet annoying things (but who knows, maybe I just have OCD!). The big issue from the first phone was the screen and the creaking, both of which are resolved with the second device, but I'm i'm contemplating whether I should return this one as well to go for one that is "perfectly built".. I mean, if this phone was store bought I would have no hesitation. I would just go there and make them open the boxes until I found a device that had no imperfections.. But it's just a real hassle having to continually ship my old device back, purchase a new one (while waiting two weeks to get credited back my $600 for the first device), and waiting for it to arrive. I also don't want to risk getting another phone with the purple tint issue..
Sorry for the long winded post, but basically what I wanted to ask was do you guys have any manufacturing imperfections with your phones??. I'm not talking about faulty screens or weak antennas, but actually design or cosmetic flaws. Do you guys have any and have you learned to just accept them or have you returned your devices and successfully gotten the "perfect" device.
Thanks, and hopefully I can get some pics up soon. Feel free to post your own so we can compare!
I got mine for free at this year's Barcelona MWC and luckyly i've had no issues whatsoever regarding hardware or aesthetics. An I say luckyly because obviously if I haven't bought it and I don't live in the US I would most definitely not get it replaced.

So which are you really looking for? Manufacturing defects or design flaws?
Are you looking for functional defects or cosmetic only defects?
Are you look for process-gone-completely-wrong defects or are you looking for minor imperfections resultant of process variation?
It is certainly possible to have a bad screen or a bad antenna as a manufacturing defect. There is also minor variation in any manufacturing process - this is normal. The trick is to keep the variation controlled well enough that the process consistently produces acceptable quality product. Note: No manufacturing process produces perfect parts, and minor imperfections are not necessarily defects. Normally, a design flaw impacts manufacturing quality only if the design requirements are too stringent for manufacturing capability.
I know you started out saying you did not want yet another thread bagging on the N1, but without clearer objectives, you've left it wide open for just that.
Mmm I love the build quality, it's very rigid and solid.
There is one imperfection that I noticed like 3 weeks of constant use.. The bottom piece, the one with "htc" on it, is a little bit more raised on one side (in comparison to the silver band on the back) than the other side. I'm talking 0.5mm difference that you can't see, only feel when comparing.
I'm writing that off as absolutely negligible and too tiny to even think about.

Same here. I thought about popping it off (it's just retained by a couple of clips) and attempting to re-seat it, but I see no problem with it. It's not like the 2nd batch of the iPhone 3G, where there was 1mm gaps between the plastic back and chrome bezel. I'm shocked no news blog picked up on that, it was fairly widespread.

Well it's the almighty apple, they don't wanna disappoint their readers that the calculator that they paid $500 for is also cheaply built.
I have a question that (um..) kinda relates to this. I'm having a hard timing saying this so bare with me. You know when technology is first released that is has alot of problems and bugs but overtime it seems that the problems die down because the companies that produce the phones (xboxs, iphones, ps3, etcs) get smarter and make things differently or better...
Well my contract with t-mobile is up in 46 days and I was planning on getting a nexus one. I don't plan on getting it engraved. My question is that do you think my phone will be made when I order it or do you believe its been sitting in a warehouse since March 26th (guess) just waiting for somebody to place a call? I've seen those cool "making of nexus one" videos on youtube and figured i'd ask you guys. Thanks to whoever answers.
yup, i have similar issues. i initially thought they actually shipped a refurb unit to me. turns out i'm not the only one. now i'm not that worried

attn1, I could have been more clear in my last statement, 'design flaw' was a vague term. I meant cosmetic only defects and minor imperfections as a result of process variation. I know that with any product that is mass produced on an assembly line you will get variation from device to device. This thread wasn't meant to bash this variation but just to compare what other people have experienced with their phones.
Like I said, my first phone was awful, it had both functional and aesthetic problems. My second phone seems to be fully functional but still has a few (albeit minor) aesthetic imperfections. I must say though, I got my Brando Gel case in today and it looks great on the phone! It covers up the unevenness on the bottom teflon piece as well as the blemish on the left side of the phone very nicely.
My nexus came with a scratch or bubble on the inside of the screens glass. They told me i'd get a refurb in exchange(even though it's about a week old), I told them i'd think about it. Think i'll be calling back and demanding a brand new device.

That kinda scares me because I'm picking up a nexus one in 46 days (contract with t-mobile will be up then) and I dont want something like that to happen to me. I'll keep my fingers crossed. I would demand a new one too
Have had no issues with mine until yesterday when the trackball stopped scrolling left. Refurb sans engraving rolling in tomorrow. All told still much better quality then my G1 or Blackberry.

No tint nothing amiss as far as build quality that I can notice. This is the best built (visually and as far as any creakiness or such) phone I have ever owned and the first one I have had without any perceptible flaws out of the gate.
OK! So to all of you who has a Nexus One with cosmetic imperfections on the BOTTOM plastic piece on the BACK, with the labeled HTC, i may have a cure for you.
So, with me I HAD a slight imperfection on the right side, about a 1mm gap. It was annoying and I have some slight OCD (used to be worse). One day last week or so, that part of my phone became VERY hot, probably 101-105℉. While that plastic was hot, it was a little bit bendable. I used a rather large amount of force, and over about three times of doing this, the plastic is flush with the metal, and the rest of the phone.
So try that if you're super partial to your device like me. Or if you dont wanna deal with HTC, like me.

"refurbished" sounds bad but really its a more taken care of device isn't it? It's been tested to a further degree so its more likely to come without flaws perhaps or am I reaching?

no. you're reaching high... its been refunded and fixed.. haha
so you are using someone else's phone who now owns probably a new device. brand new is the way to go, especially if your device is a week old...

[Q] Problems occurring in batches?

After reading all of the crappy review for the transformer, it looks as if 50% are happy 50% are not.
I am wondering if the problems are occurring in batches because I just ordered mine from American TV and it will probably be here tomorrow or the next day.
A lot of the problems I have found are from the batches that have already been purchased and I don't know what to think.
Two things:
When asus was first bringing these to market, it could the problems are coming from they just naturally skimped on manufacturing quality because they are so damn cheap. Or they had a bad batch to get them to market quickly.
Asus could also just had normal manufacturing quality before and NOW since there is a high demand, newer units may experience worse manufacturing quality. Or they could be better because they knew of the problems.
Hope its not too confusing, what do you guys think? Newer units = worse quality? Older Units = better than newer?
i think logically you could expect the first units to have the most problems, however, we dont know if asus had enough complaints, or realized that there are defects (if there are--aside from software side) to be able to retool and make changes during the assem process to produce better revised hardware.
I actually gave this exact topic a lot of thought a few days ago, i thought about everyones complaints and how it was hit/miss it seemed, and i wondered whether the people that are complaining were truly the "first" adopters and got REV 1 hardware. Obviously, since they are playing with the tab and most of us are anxiously awaiting its arrival i would assume it just may be the case. Heres to hoping that these little glitches were an easy fix at the factory level (but knowing how they operate i doubt its a simple/cheap/quick process, which makes me doubt that the tabs that me and you will receive this week will be any diff from the ones recieved by the people last week and the one prior. the time frame is just too small, but then again, anythings possible).

Definitely have to agree. My guess they are the same and it is so difficult for Asus to actually respond to problems and transfer a fix to the manufacturing of the units. The only real thing I am worried about is the light bleed/dead pixels.
Moreover, the problem seems to be 50-50 and my estimate came from the assumption that there is manufacturing quality loss through increase production speed to meet the high demand. I tend to believe this because of the poor quality control. I am assuming (after reading the post about the guy receiving a 2.2 model) is that they do perform screen quality checks, to a certain extent. Some may have just slipped out.
Lets just hope we get a solid model.
I tend to side with the second poster...it's all about quality control....how many get out the door without their defects being noticed OR....being flagged as a defect.
I've worked around assembly lines all of my life...25+ years and I can understand some defects got through unnoticed....but the question is: when were they noticed and what steps were taken to prevent the same issue from occurring again?
And the second point is valid also....speed equals a mindset of "this one little corner-cutting decision won't make that big a deal in the long run...."
Unfortunately, rushing things to market to fill orders at a breakneck pace means that issues are more likely to get by...that's a fact of life.
When cash is on the line...decisions get made that might not otherwise gotten made.
I hope mine comes today without the glaring errors that I've seen here...crossing my fingers...
My only real complaint is the light bleed. I know it isn't the only device that's had this problem. I remember when I was reading the Evo 4G forums it had a similar problem when it first came out and recently the iPad2 had light bleed issues too.
The light bleed isn't a huge deal, but it is distracting while watching certain tv shows and movies imo.
I've had 3, first one was the very first batch in the UK, arrived mid April or thereabouts. The next one was around the end of April and the the latest one I received around the 6th of May.
1) Mid April
Some lightbleed on 3 of 4 edges. Perfect screen in terms of pixels. Imbalanced speakers. No sleep of death in 2 weeks or so. No gap in glass.
2) End April
Terrible lightbleed. 14+ stuck pixels (I gave up counting). I think the speakers were imbalanced too. No sleep of death, but only used it for a few minutes. No gap in glass was noticed.
3) Start of May
Some lightbleed, probably akin to 1. Around 8 or so stuck pixels, seen on black screen. Perfectly balanced speakers. Had 1 incident of the sleep of death within 5 days. Glass does not fit perfectly on left hand side (gap of 1-2mm allowing dust inside and glass to be lifted by nail)
Had I known what would happen I would now gladly stick with the first! So, from this small sample it seems that in my case the earlier devices were better in some ways but not in others. We'd have to have a huge sample to be able to answer definitively. I still love the tablet though.
I have a first US batch version and it's fine.
This is why I just ordered the Acer. I got mine and had some light bleed. It got worse. The creaking got worse. Now there is a small piece of dust under the screen. It is not very noticeable except on white background but it worries me that in 6 days of ownership it is getting worse. I now see a dust spec under the camera glass.
The edges of all the ports are razor sharp and can take off skin.
I love the weight the price and the ups screen but the build quality is very disappointing. If it was only the light bleed from day one I would keep but I can't handle how much more has happened in 1 week of ownership.
I got a 32 DB Livonia using coupons from staples for only 40 dollars more than a 16gb Asus cost me. The screen in store was quite good. The build quality seemed much better and despite the added weight it seemed more comfortable. To hold given the curved shape. If availability were better maybe I would exchange my Asus but no stock around.
in the end I might just opt for the new galaxy tab as it seems to be most like the load in size and weight.

Just received
I just got the TF in the mail today. It is nice.. but there are some drawbacks from the xoom that I miss.
Xoom felt nicer in my hand and had that led notification. But the screen on the TF is WAAY better.
I do have light bleed in small sections, not terribly noticeable. Speakers are fine. no dead pixels, yet. not really a creaky sound, just when I press harder than normal on the screen. No glass misaligned. I will seal up the beast with a vinyl cover. Screen is responsive, no probs yet.
A bit disappointed
I received my TF this Thursday and was so very happy. After unwrapping it I pressed the power button and I got nothing. I thought OMG it's not working. Then I thought, maybe they didn't have time to charge the battery. So I charged it. I checked on in within a hour and pressed the button and it came on. I began to play with it and realized that after the TF wasn't in use for more than 5 mins the power button whenever pressed didn't wake the TF up... SO i pressed and pressed.. nothing.. so I waited about 30 sec after a press of the button and it came on.. After going thur this over and over I figured it was a defect and I RMA'ed it. I'm hoping that they didn't just push out a product that will have a lot of issues...
Here's my two cents:
Got my TF from Fry's in LA on May 5th. 32GB don't know manf date.
For light bleed - minimal sround the left lower edge and upper right edge. Dark room, bright up full, about a 1mm bleed - very slight and almost unnoticible.
Running latest update with no issues, just updated again today with no issues.
Sometimes after a long sleep it won't power back up with the power button, so I press the vol down and pwr at the same time (shut down) and it shuts down and restarts fine...Seems a sw glitch.
Other than that it's an awesome machine!
Dock - arrived on the 12th. charged up fine, docked fine, no mouse, brick or other issues other than the backspace key is touchy (actually not touchy -takes some effort), but all other keys work well. I think I'll RMA it later depending on how many show in production (I can live with this for now).
Case - had to cut a small hole in bottom to allow charging while case is closed. Otherwise great.
I hope this helps.
BTW, I don't follow these threads too much, so if you need something please PM me.
I feel like I've said this before, but I'm honestly surprised to hear of all of these issues. Mine doesn't seem to have any of them. No gaps around the screen, the glass fits perfectly, the casing for the tablet seems sturdy and doesn't budge at all. There's very little noticeable light bleed, if any. I've never had anything like a "Sleep of Death". I couldn't be happier with the quality of this beast.
EDIT: I should mention I have a 32GB version that I purchased from TigerDirect on Wednesday, got it this past Thursday.
My tablet and dock were among the older units. I had only one instance of SOD and the green screen with the camera issue which has been fixed via firmware update.
The tablet itself appears to be of high build quality,the bezel is secure, no gaps around the screen seal, no dust,no dead pixels,very minimal light bleed that I had to actively look for.
no problems to speak of
eGoing on 2 weeks ownership using various each day.
The only thing a few times I've come back to an unresponsive unit. Then I just held power button down 10 seconds and then rebooted. I take that with a grain of salt.
But. I am not going to update software for another week or so. Until I read more positive reviews
Many problems with mine
I ordered mine from The Best Buy batch on May 22nd, and it came with a not-smooth not-particularly-responsive screen; it then got two light leak spots, the clock disappeared from the menu bar once, and it bricked when I ran the 3.1 update. I sent it back, but I wonder, are the screens really not as smooth or responsive as the Xoom or Acer A500?

Dust under screen

So I have a few specs of dust under my screen. One makes the screen look like it has a dead pixel. I called Samsung and they want me to mail it in. Pry 7 day turnaround. I bought it out of town which is s five hour round trip so an exchange is possible.
I have an ipad 2 so I would only be having small withdrawals from my tab.
Should I go ahead and send it in and hope for the best or plan a road trip. I'm leaning towards shipping it as they are paying both ways. So zero cost.
Anyone else have dust and what would you do.

Got the same on my white galaxy tab 10.1 that I bought at Best Buy two days ago (maybe part of the initial Google I/O limited edition batch?).
I see four particles of dust but only when there is direct light over the screen. Thinking about exchanging it.
A curiosity, is your tab the white or metallic gray model?
Thanks!
Had 8 specs of dust under the screen towards the top right... made me so angry I returned it and plan on waiting for a better quality tab
I had one speck and planning to return it at BB. I got the white 16GB one. I'm afraid that the replacement will have more.
Sent from my GT-P7510 using XDA Premium App
Are they visible under any conditions or only under certain conditions (e.g. direct sun light over the screen)?
I had this issue with 2 tabs, including the one I currently have. I saw it, exchanged it at best buy, and the new one has it too. I'm waiting for them to get a new shipment to exchange it again.
Silver 32g
The dust is visible from all angles, even when the screen is off.
I'm waiting on an exchange unit from compusa because my first tab had slight light bleed, specs of dust, and liquid-looking blotches under the screen only visible under direct sunlight. It also had some type of big, weird, dusty looking spot under the screen. when I first noticed the light bleed i was ok with it but after i noticed the other issues i decided to return it. I'm afraid the exchange unit will have these issues so I believe I should have sent it in to Samsung. It probably would have taken longer but atleast they'd make sure I received a tablet without these screen issues... probably lol but who knows?
I didn't take the dust under the screen thing that seriously, until today when I used my tab under some bright lights and noticed a glaring white piece of dust in one corner of the screen. Highly reflective on a black background and relatively noticeable. I'm really pretty amazed. I'm still within my Best Buy return window, and will probably bring it back tomorrow.
I'm curious, for those who returned it to Best Buy, did you tell them the true reason you were returning it and did they give you any trouble? Or did you simply say you weren't happy with it?
For those who exchanged, did any of you ultimately get a perfect unit?
Not sure if I should accept a single piece of dust in the far corner of the screen, or gamble on getting a perfect screen on the next try. Won't be much of an improvement if the next screen ends up having 8 pieces of dust and a couple of dead pixels.
Edit: Just got curious and took out a penlight. Found two more central pieces of dust under the screen. Best advice to new GTAB 10.1 owners - never look too closely at your screen. You might not be happy with what you find!
just made up some BS about other issues you have with the tablet.

Yup, thats what I usually do if I have a dead pixel. Not worth aruging with the salesperson about whether its a "Significant Defect". Was just wondering what Best Buys current attitude toward these things was.
Edit: Just did the next obviously necessary thing: ran the penlight over my XOOM screen. Found extremely small pinhead size specs in a few places which seem to be parts of the screen surface with slightly greater reflectance, but nothing that appears to be dust. So, the much criticized XOOM screen seems to be dust and dead pixel free, at least in my case.
Mistery solved
I returned my Galaxy Tab to Best Buy for a replacement. I opened the new box crossing the fingers and ... the new tab was flawless! Zero dust anywhere!
Two days later I noticed two specs of dust under the screen. Hmm, I thought I did a pretty accurate inspection... I checked it very carefully again. Only two very small specs of dust: one on the right and one on the left side of the screen.
Today I check again and I can count eight specs of dust!
Is it possible they enter from outside?
I checked for possible gaps between the glass screen and the plastic case and I found a gap all around the edges of the glass screen. Not large but I can stick a sheet of paper in it.
Another possible explanation is that dust enters from the speaker grills and the connector socket. The position of the specs of dust is close to them. I think that the latter is the most probable cause.
Anyway, it is a fact that this is not dust that was trapped during the build process, this is dust that entered the tab in the 4 days that I used it. This means that the dust will keep accumulating: if I got eight specs of dust in 4 days I can imagine what I can get in a year!
This one goes back to Bets Buy too and this time for a refund.
It is really a pity, I really liked this tab!

Unfortunately the screen is still quite horrible.

I returned my tab to Best Buy (2nd return, first was because of lcd defect [rainbow sheen]) the second one I got was a white one that had dust under the screen. Looking over their return policy there is nothing other than the standard "we reserve the right to refuse any return/exchange" disclaimer. Those of us experiencing these issues, please do the rest of us a huge favor when returning your tablets, don't lie or misrepresent your reason for return. Be honest with the person handling the return, thereis no valid reason that they should deny it. Hopefully Best Buy will clue in with the amount of charge backs they're hopefully going to have to do in the near future.
The only thing that really pisses me off in regards to the whole situation is that none of the tabs the have left have unlocked bootloaders. It's almost insulting that the first 5 that samsung shipped for release day and none of the secondary shipments do.
Except that best buy is now requiring valid id for returns because they are tracking what people exchange for some reason. Eventually they will stop you is my guess but who knows. Just be careful.
Well along with dust under my screen...somehow a small bug got under there too.
This is very frustrating...
Sorry for the crappy quality

Just received my third tab..
First one had minimal dust specs and screen separation, se ond one had fingerprint like smudges and dust particles under the screen and screen seemed loose, my third one has a tighter screen and only 1 dust particle...
I think i will just keep this one...

I have 1 speck of dust; unfortunately it is half way down the luminous battery icon so very easy to spot if you want to find it. I noticed it right away and haven't had any new pieces since then (2 weeks). Mines is the black 16gb UK one.
If it had not have been over the battery I would never have seen it and it does seem to be moving slightly so I am hopeful it will one day hit the black status bar and disappear. It depends where these things are as to whether they are annoying; personally, I get the odd speck in my eyes every now and again and you don't notice it after a week or so. The advice not to go looking for them is very good - you may well not like what you find but also it's not the end of the world if the device functions. The first scratch anywhere is the worse on any device but after that you realise it is no biggie. My ipod has a giant crack in the screen so it could be a lot worse.
I went through two 32GB at Best Buy both with horrible (5+) pieces of dust under the screen. The second one had like a piece of string or something a couple mm long under it. Third unit appears completely flawless (for now) and I am quite satisfied.
Is anybody using any kind of case? Or just naked?

[Poll] 10.1 Retail Build quality survey, please participate ...

Dear Galaxy Tab 10.1 (RETAIL) owners,
Please if you can participate on this survey.
Retail means the one you bought at NY June 8th and/or after June 17th.
If you have exchanged one, let us know what was the problem?
Hardware issue like screen bleed, cracking speaker noise, wi-fi issue, etc ...
Or probably functionality issue like bricked, boot loop, etc ...
With this poll, we could get a rough picture about how well the manufacture / production of Samsung Galaxy Tab 10.1 (Retail version), Samsung QA, those kind of things.
None of the reported issues here.
Hi, thanks for your input.
Please if you can vote in the poll.
The poll options was created a bit late

I've gone through a looooot of Android devices lately and I can honestly say this is the first one I have not had to exchange. I'm very impressed with Samsung.
Mine is perfect. I am impressed.
Exchanged mine 3 times.
First unit bought on June 15th in NYC had an "oil spill" effect under the screen in one spot.
Second unit - display light bleed in the lower left corner.
Third unit - dead pixel.
Last unit seems to be ok.
I had the "oil slick" issue under the glass...my new one is on the way so I'll respond to the poll when it gets here.
I had to return my first one because one of the edges was rough to where it seemed as if the paint quality was bad. My second one is perfect though!
Lol... the results from this poll is an exact reciprocal of the Asus Transformer polls.
I will be exchanging mine today. there is a bulge on the back where it looks like they forced the cover onto the device with a loose screw or worse a broken component.
Mmm ... I dont understand what you mean

Can you guys please explain how you found these issues I think we all want to check ours throughout. To find oil under the screen was the display off in order to see? Back light bleeding can you just check by pulling up a black image and making sure nothing is bleeding through?
So far mine is perfect I haven't noticed anyrhing!
Returned my first one. Was having lots of wifi problems. Got a second one and about 75% of the wifi problems are gone now and I think the other 25% of my wifi problems could just be crappy apps (Pandora and TuneIn Pro seem to really suck on my tablet).
I think I got a good tablet this time. But Android 3.x and app bugs don't make it easy to be sure. Haha.
So far, so good
Received mine on the 20th. It's a little early to make a judgment with a high degree of confidence, but no issues to date. Clean unit here.
I just got mine today, so im still checking everything out, but no issues so far. Exterior build quality looks good and no real software problems (had minor issue connecting to my wifi, but a modem/router reset fixed it).

Exchanged mine twice.
First had light bleed. Second had screen separation. Hopefully the 3rd time is the charm.
I had the IO version and it felt cheaper and plasticky but this one is sturdier. This device has an even ring around it whereas the IO devices were thrown together test manufacturing models. No issues here.
I noticed the back of the tablet below the camera can be flexed in some. Not a big deal, but it felt kind of odd.
I was at the launch (of s2).here in dubai - about 2 devices had oil spill (mind you'll this was a demo unit - one was a 8.9 and other was 10.1)
I'm having double mind of shipping it in - i'll pick it when it's locally available

32 GB hardware defects?

Does the nexus 7 32GB still have the same defects? If the defects are still present I'd rather wait for the nexus 10.

Most posters on this forum have never seen a defect on the Nexus 7, so your question is kind of hard to answer.
I know mine is perfect for what I want, and it goes with me everywhere.
In answer to your question (rather than avoiding it and saying something which from my reading of this forum doesnt appear to be true), yes, the 32gb Nexus 7 is the same design and build quality as the 16gb Nexus. They still ship it with missing screws on the left side in an attempt to get around the left side screen lift as an example. This is the case on CA0 (October build) Nexus's.
Quality control on the Nexus appears poor (left side screen lift, dead pixels, light bleed, spongy feel, speaker problems) and the design is obviously screwed up - hence removing screws at source to try and get around it. My Nexus worked fine and looked perfect when I got it, but two weeks of light use and it had very bad screen lift, with an audible creak and rippling on the screen. I wont get one unless the design changes and we do not get machines turning up with missing screws anymore. Its not acceptable.
Currently I am probably going for a Samsung...if they are built as well as the initial reports suggest.
tl;dr: The 32gb Nexus 7 is the exact same design and build quality as the 16gb.
amount of people with problems on the 7 are WAY overblown and dramatized on this forum.
I have no dead pixels, no light bleed problems, no speaker issues, slight screen lift we're talking barely perceptible (which is typically the case). What I DO have is a insanely smooth running, highly portable, great battery life tablet just like most users.
I would take peoples obsessive scrutiny with a grain of salt, they're just looking for problems that don't even matter instead of just using the device. I would still happily recommend the 7 to anyone, the 10 is no substitute. I have a 10" tablet in addition to my 7 and it never gets used because its simply too heavy and too large to carry around comfortably. You can also use the 7 and not look like a weirdo in places that a 10" stands out.
I would have to disagree. I bought a c80 less than 2 months ago. Had minor screen lift which I accepted though technically I shouldn't have been OK with. The only reason I didn't RMA is because of the many reports of terrible experiences with Asus.
Last week the speaker somehow broke overnight and now I'm having to send it back. I have also noticed terrible IO performance of the n7 when compared to both my HTC Onex and my old nexus one.
