Hey Guys,

Are the C9O available here in the US?

I was nexus hunting since Monday and so far all I find are C8's.

Tried Microcenter, Gamestop, Staples, Office Depot .. all C8's and they are claiming that those are newly shipped stock.
[Nexus 7 General] SPreston2001:
Come on guys lol. There's nothing different about the C9O model that warrants not buying a C8O lol. Besides the screws being left out on the side nothing has changed. Buy the tablet and enjoy it....
[Nexus 7 General] julianlyle:
I already had a C8OK with screen lift and returned it. Hopefully there will be more Nexus 7's with a flush screen than on any other model, this is why I'm asking about details.
[Nexus 7 General] olivercervera:
No lifted screen, it's perfect! However, a friend bought Nexus some days before me: it's C80 and he does not have problems. But C90 it's more cool, has 4.1.1 onboard! lol Love my Nexus7!

[Nexus 7 General] badasscat:
All Nexus 7's have 4.1.1. The only difference is apparently the "S" vs. "D" build. And who knows what the actual difference is...
[Nexus 7 General] bmwaudio:
not quite, i have a C8OK, and mine had 4.1 stock, prompted me to update to 4.1.1, but i had already rooted, and chose to not upgrade to 4.1.1, saw they took out the iphone like search or something like that in this version??
[Nexus 7 General] yabbandroid:
Oh no, I have a C80, I'm happy but I'm scared every day I get a screen lift issue :(
[Nexus 7 General] Spacemonkie4207:
Just exchange my c80 for a c90, screen lift on left side and dead pixel on right edge of screen.

---------- Post added at 05:26 PM ---------- Previous post was at 04:56 PM ----------

Lol in line exchanging now, hopefully 3rd time is a charm.
[Nexus 7 General] julianlyle:
Keep us posted!

[Nexus 7 General] Spacemonkie4207:
Third time is a charm, screen isn't perfectly flush but good enough, seems like they all have the left side raised a little bit, not that big of a deal. No dead pixels and speaker sounds great. I used screen helper to look for dead pixels and found none.

First time using the screen outside on a sunny day, is it ever a bright screen, can read it perfectly.

Build model is JRO03S.

The c80 I exchanged was just as good as the c90 I am holding in my hand. no difference.
[Nexus 7 General] TECK:
Every batch had a certain number of perfect flush screens, getting a C9O does not mean all problems will be fixed. IMO, the only major improvement we will see is related to actual screen quality, not the actual physical hardware design (i.e. screen lift, control buttons, headphones jack, etc.).
[Nexus 7 General] xrtreas:
Spacemonkie, did the c8 have the lift and dead pixel or did the new c9?

---------- Post added at 05:23 PM ---------- Previous post was at 05:18 PM ----------

I just got my new c8 from Staples earlier this week after a couple of screen-lifting prone units. This C8 is perfectly flush. Only problem is the screen touch response freaks out if I don't hold it with my other hand. Major cross axis, nothing like my last too. Could this problem lead to anything else?
[Nexus 7 General] DoctorScientist:
Got a C8O atm and I am debating if I should try and get it replaced with a C9O.

Although I have slight left side screen lift it's merely a cosmetic issue and doesn't actually affect the device in any way.

With all the various trends relating to screen lift issues, serial numbers, and "permanent" fixes my question is if the screen lift actually reduces the Nexus 7's functionality or if owners just want a solid device and not have to worry about it getting worse down the road.
[Nexus 7 General] Psychosi42:
I returned a C80 today that had screen lift pretty bad. Microcenter only had more C80's to replace it with but the one I got is flawless.
[Nexus 7 General] TECK:
One thing is sure, I'm keeping the current C8O that I got few days ago. The previous tablet had a weird bluish white tint and washed colors. I fixed the minor lift easy and the screen is simply great, color wise. I imagine it will be even better, when they release JRO03S to everyone.
[Nexus 7 General] LearnIIBurn:
I have a c80 as well and my speakers are messed up and the headphones jack is really nasty. I'm gonna warranty mine as well :(
[Nexus 7 General] olivercervera:
I was talking about the software out-of-box

:D

When you say the speakers are messed up, exactly what's happening? Seen the problem mentioned a few times but not sure exactly what it is. My speakers seem on the quiet side but assumed that's just how they are.
[Nexus 7 General] julianlyle:
He might be speaking of crackling speakers. That's my guess-
[Nexus 7 General] shook187:
When will the day come that every other thread isn't about screen lift?
[Nexus 7 General] julianlyle:
When the lift is gone, maybe?

As far as I know this thread is about the C9OK model.
[Nexus 7 General] DoctorScientist:
Yeah I saw your thread/guide and wanted to do the fix myself but couldn't find small enough spacers. I only have screen lift but would be super annoyed if I had bezel spacing like your last pic. Since it's be a few days since you got your new C8O how is it holding up? My main concern is what another member brought up about possibly putting additional stress on the plastic tabs and having them crack eventually.
[Nexus 7 General] Spacemonkie4207:
all 3 (c80 and both c90's) had a slight lift. It's so minor that it doesn't bother me at all. I also use a case. My advice, if it works, enjoy it, unless it has dead pixels, I used to have a Playbook sent it in to get fixed 3 times 4th still had dead pixels but the were on the bottom corner so I didn't bother sending it in again.

Any device that is mass produced in Asia and the people assembling the device are getting 2 dollars a day and working 20 hour shifts is not going to be perfect.
[Nexus 7 General] TylerDurden1999:
I just bought a Nexus 7, C80 unit and has NO PROBLEM at all.

I runned all the tests on it and everything is fine.

No flicker, no screen lift, no bleeding, etc.

It is flawless.

Build number ends with a D, not an S.

So it depends exclusively on luck.
[Nexus 7 General] TECK:
Could the people who get a flawless device post a pic with the tablet positioned at this angle?

(camera should be on the right side, when you take the picture)

Look at the rear of the picture to see how the screen lifts.

This is how all my 3 tablet looked when I got them and the screen is definitely not aligned to the bezel.

My last tablet had also weird spacing between the bezel and screen:

Thank you for sharing your screenshots, it will help others.
[Nexus 7 General] 513fabe:
Just bought a c80@Walmart. First run with it I don't notice any problems, knock on....uh dammit no wood so knock on nexus.lol..

Hopefully won't be updating his to report negative review, Walmart clerk did say theye had this stock of n7 or a while.
[Nexus 7 General] Spacemonkie4207:
The screen lift people are talking about is so minor, you're not going to get a perfect device, just enjoy it!. Dead pixels or not being able to charge, now that's a different story.

[Nexus 7 General] sol_671:
Just got my nexus 7 C80 2 days ago everything was perfect until one dead pixel appeared, my friends suggest of returning it but afraid I might get a worse one, the dead pixel is not noticeable unless the whole screen is black, should I worry that more would appear?
[Nexus 7 General] altimax98:
Im finally going to breakdown and get mine replaced. It has a washed out screen and some lift. But i could live with it. Now though the lift has gotten worse, and no fix can fix it. Its over the trim on the side on mine. Its bad.....

are you guys who purchased though Google play going through google?
[Nexus 7 General] keplenk:
So I got the C90 earlier in GameStop.

Just got home and did initial testing.

First thing I found is that there is 0 screen lift. It is nicely seated.

Colors are brighter screenshot below:

http://imgur.com/7q0Zk

Left is the C90, right is C80 (borrowed from my Mom)

The white is much much whiter. Other colors are almost identical - you just notice it in white being more white.

But damn, my newly purchased C90 has 2 dead pixels in black screen. It is so small though and I think I can live with it .. but I guess you can't find a perfect purchase.

If I find the dead pixels to be annoying, ill have it replaced but C90 is rare to find. I might wait at least 2 weeks.

EDIT: My Mom's C80 has a very minor screenlift.
[Nexus 7 General] xrtreas:
I think you mean stuck pixels(white/colored). If they were dead(black) you'd only notice them while not having a black screen.
[Nexus 7 General] keplenk:
Oh .. yup .. i guess it is called stuck because I can't see it in other colors.

No worth returning right? I'm torn :(
[Nexus 7 General] julianlyle:
Sometimes you can fix it, leave it with a stuck pixel app running for the night.
[Nexus 7 General] MattSkeet:
What about screen flicker on WiFi?
[Nexus 7 General] bluefear85:
Since last week, I've been going to all kinds of stores in my area to see if they carry any C90's, no luck. It's pretty funny when some of the store employees give me a funny look when I ask them if I can check the serial number on the box before I buy it. I always tell them that I've had bad luck with these before...sent 2 of them back that I ordered from Google in July.
[Nexus 7 General] TylerDurden1999:
I thought my device is flawsless but while i was typing a message on it a sensed a bit of screen lifting on the left side(where is the dock connector) and indeed it its.

It is not on the corners but between them.

I cant even distinguish it by just looking at it, only if i touch.

I am wondering, the screen lift issue can get worse?

Other than the screen lift issue my device is perfect.

No bad pixels, no screen flicker, etc.
[Nexus 7 General] 513fabe:
nexus7 return and ustom roms?

would return it. If you bought at store you can see if its a c80/c90 etc.. on the box, just slide the cover thing off its on SSN I believe, besides being on the sticker stuff on the actually device...

Also, to SPACEMONKIE or anyone do you really think its worth it running custom Roms? I have rooted since I had HTC hero, and run custom roms on my gnex, but I am curious as to any real benefit..

Ps. I'm not a noob so please don't respond like I'm one. Hahaha
[Nexus 7 General] Nospin:
The most exciting thing for me about the new model is the new build of Jelly Bean. Does anybody have any idea what it fixes? Color saturation during video playback maybe?
[Nexus 7 General] zarish:
I was feeling mine was pretty perfect a few days ago but just as I posted in the other thread I am now considering returning it as well.

I've had my first dead pixel appear. Nearly right in the middle of the top half of the screen (starting calculator in portrait mode the pixel is right in the left corner of the COS button). And now also noticing some slight lift on the left side.

Whereas I used to be able to run my finger down the left side and have it slide along the silver edge that was just slightly above the height of the screen it now slides off sometimes and instead I can touch the glass edge from the outside. Even being able to set my finger in these spots on the silver trim and then run my fingernail against the glass.

Wondering if I should start going to try hunting around and seeing if I can find a C9O or at exchange for another unit at any rate?

Can we expect these issues to get worse?

Should we be worried?
[Nexus 7 General] TylerDurden1999:
That is pretty alarming.

Dead pixels popping on the screen randomly.

That's not acceptable.You should exchange it.

I hope mine won't get dead pixels or something like that cause i am gonna exchange it right away.

I head that screen lifting won't get worse, talking with some n7 users that have the problem.

Mine has a slight screen issue, you cannot even see, only if you touch.

I got 30 days of testing it from where i bought it and if the screen lifting worsens, i am definitely thinking of buying another tablet.

I really dont wanna do that, cause the Nexus 7 is so great, i love it but these flaws are dissapointing.

I got a wireless router from Asus(RT-N16) and it is uberly good.No problems with it at all..

Hope that will stays the same with the N7.
[Nexus 7 General] ecki2k:
Got my N7 c9o a week ago, so far I'm happy with it.

Screen lifting is present but so decent you can only feel, not see it; I'm okay with that.

Only disturbing thing: the acceleration sensor is not calibrated and it seems one can't fix that permanently.

Otherwise I love the device. No lag, multitab-surfing smooth as butter... I think I'll keep it as the gyro-thingy can be compensated by tilting the device slightly while gaming, no dealbreaker.

For 250 euros, this is by far superior to my allwinner a10 10" tablet. By faaaaar.

This is disappointing to hear (well read) that the C9O run still have the same dang problems. Maybe when they get to C10O they will have this figured out?

I just sold my Samsung Galaxy Tab 8.9 (LOL had it less than a week but made a 50% profit on the flip) and was going to take another look at the N7 since I still have my OTG cables, couple of cases, etc...but perhaps the slightly crippled yet probably better built Fire HD might be the route to go???
[Nexus 7 General] chug:
just got a C9O and it doesn't seem to have any screen lifting. the one on display at staples definitely had noticeable screen lifting. Not going to do any closer inspections because I know I won't be able to unsee it if I do find something :)

anyways, seems like the C9O models are starting to get better.
[Nexus 7 General] julianlyle:
No one with a C9O checked for missing screws?
[Nexus 7 General] keplenk:
I had my c9o replaced with another c9o (first one had stuck pixels).

This one is better.

So far no issues at all. =D

I hope this is my last

Anyone hunting c9o - go for Game Stop.
[Nexus 7 General] zarish:
Just exchanged my C8O for another C8O (no C9O nearby).

New one has no dead pixels and no screen lift, going to run it through it's paces.
[Nexus 7 General] kryptoniteguy:
That's where I got mine too... took my 70 back to WalMart and called around until I found my 90.
[Nexus 7 General] vandermark:
First thing I noticed after I received my C90 model: the screen is more vibrant, my first model was less colorfull. As a photographer I am very precise on these things: color reproduction is definitely better on the C90 model.
[Nexus 7 General] Lesser Version:
I returned a C70 for a C80 and have had no issues whatsoever. I think no matter what batch has been produced, you are always going to have lemons in the batch. You still can't beat the price for what you are getting.
[Nexus 7 General] ASavva:
I own a C60 that I pre ordered before release and I have not had a single issue with it yet. All this talk of older models being rubbish is ridiculous.

Just because it's a newer model doesn't mean that it's going to be fault free. Mine is perfect and I wouldn't trade it for anything.
[Nexus 7 General] julianlyle:
Cool story, bro. We're talking about the C9OK, not the C6OK, kthxbye.

Has anyone confirmed if the c9o version uses a different display?

Also, does the c9o version still exhibit the flicker issue (i.e. the one related to wifi transmit power)?
[Nexus 7 General] jaju123:
I'm pretty much 90% sure that in order to get an understanding of how good a new revision of a product is, you must compare it to those that came prior. Is my logic at fault here oh mighty Thread King?

---------- Post added at 05:12 PM ---------- Previous post was at 05:11 PM ----------

There are pictures on this thread that show a difference for sure, with whites being whiter etc. However, I don't think there is confirmation other than the pictures others have posted.
[Nexus 7 General] magnetz:
Is it definitely more accurate colour or simply brighter?
[Nexus 7 General] guih:
I finally got my N7 today and its working flawlessly so far :D
[Nexus 7 General] julianlyle:
He was saying how good his C6OK was in a thread that's about reviewing the C9OK model. I don't see that as something logical since you can post that in every other thread that talks about the nexus in general, not about a specific model that's not C6OK.

The only thing that has been confirmed from other users is that the screen has whiter whites (not the blueish ones that we've seen so far).
[Nexus 7 General] adfad666:
Could someone with a C9O can do a backup and compare it to the older ROMs to see which files have changed?

Perhaps the screen hasn't changed but rather they fixed / tweaked the display drivers in the kernel.
[Nexus 7 General] Lpuboy87:
just picked up my nexus 7 last week..it was a C9O. Screen was fine...pixels were fine..speaker is fine. So far all is great. Running paranoidandroid but still on stock kernel. :good:
[Nexus 7 General] hbkmog:
Where did you pick it up? I ordered from Playstore earlier this month but it's still c70 models.
[Nexus 7 General] Lpuboy87:
well im in germany right now so i picked it up here at an electronics store because they just started going on sale here earlier this month so it beats shipping one over from NYC and getting hit with taxes. The back of the box is in german so I guess europe got C9O's since its the latest one and they just went on sale here like i said. I opened it in the store before leaving to make sure at lease the screen wasnt lifted. Then at home ran the pixel test etc etc
[Nexus 7 General] kench33:
Is the c90 on the box? Looking to pick one up from walmart but only if they have a c90 model
[Nexus 7 General] Neo3D:
Dell vs Nexus vs ipad

This is a c8O model:
[Nexus 7 General] ExploreMN:
I have no idea why, but from this image, the N7 looks even better than the iPad 3, which I doubt is the case in real life. I mean I think the N7, overall, is a better piece of tech...especially for business use, but even I...a die hard Apple hater...admit they got us on the display...and for 2.5 times the cost and less functionality, they better!
[Nexus 7 General] Lodovik:
Let's not forget that what we see here is also dependent of the camera used to take the pic and will also be altered a second time by the monitor displaying it. Maybe good to compare brightness and contrast though...
[Nexus 7 General] Bossbollin:
C70 Model here. Picked up approximately 2 weeks ago from Office Depot in Seattle WA. No screen lift or pixel bleeding.
[Nexus 7 General] ASavva:
I was stating that my C60 has no issues and contrary to what people say in this thread, they are not all plagued by issues.

So although a C90 may be excellent, people should not dismiss older models.

But thanks for your approval o'mighty...
[Nexus 7 General] leotnnz:
where do you get it, man?
[Nexus 7 General] julianlyle:
You can check it on the box on the side that shows the ssn, it should start with C9OK.

How are the speakers for you at max volume? Mine can't go past 50% without the sound distorting so I'm considering an RMA
[Nexus 7 General] kieso:
I would RMA if I were you. Mine is a c70 and I can turn my volume to the max
[Nexus 7 General] ClintvL:
I got a c90 5 days ago and its perfect, but I noticed a minor screen lift on the left side (~0,2mm). No problem in my opinion...
[Nexus 7 General] kench33:
Do you guys think I should just get a c90? My walmart has c80s
[Nexus 7 General] SPreston2001:
Lol I honestly dont think anything has changed from the C6O to the latest C9O builds. Its just when they were manufactured. Nothing on the inside has changed nor the manufacturing process. Just go get a tablet and stop worrying about such minor cosmetic issues. Dead pixels, bad speaker, screen issues ok fine thats understandable, but running around like a chicken with its head cut off becasue your bezel and screen are ever so slighty off is rediculous lol. When I got my C8O last month I noticed nothing different about it besides the notches on the box to make it easier to open. Just enjoy the thing...
[Nexus 7 General] kench33:
Alright thanks for the tip man. I was only going to wait until I got some more cash
[Nexus 7 General] kenyee:
was hoping to get a C9o from Staples, but ended up w/ a good C8o instead today. No dead pixels...nearly no lift on left side. No obvious flickering like the previous 3 C6o/C70's from a few months ago. There might be a very slightly flicker occasionally when scrolling in Maps, but I'm not sure if it's from screen refresh or the grounding issue.

So, not all of the previous versions are bad...
[Nexus 7 General] altimax98:
I just got a C80 replacement from Google. Im real happy with it. Next to no light bleed, just a slight bit on the left side lower corner. Its solid though. My C70 feels like a toy in comparison. No creeks, or lifting at all. The screen has no dead pixels and it is better controlled then my C70. Its less washed out, the blacks are blacker and contrasts are better and this makes the lines smoother and more distinct.

Im gonna miss my day1 device, but o well....
[Nexus 7 General] icytrey:
Went through two c80s from office depot. Both had noticeable screen lift.. went to Hhgregg (tampa,fl) and got their last one which was a c90..no screen lift. The only other difference was that it already had 4.1.1 on it. The c80s had to update from 4.1.....keeping my fingers crossed.. put it in a case so I can't see the bezel. i'm going to try to forget about possible screen lift, and just enjoy my tablet...lol
[Nexus 7 General] keplenk:
Hey guys, since this is a C9O thread and I have a C9O,

I know the build is kinda different that the older models but I'm just wondering before i do it.

Yes, it would be kind of ridiculous to change it after every build

[Nexus 7 General] swisstourist:
C6 still fine...

After 1 month of use. no light bleeding, speaker ok, no dead pixel...

Just maybe 0.2 mm screen lift on left side and plastic frame slightly bended 0.2 mm too maybe.... . But by normal viewing I don't see anything.
