I received a non-defective C9O...so far everything is fine (its been in use for 3 weeks with hd movie streaming rendering via S/W Decoder), but I`d like to know wether theres going to be a C10 charge or not? (i have an extended warranty and if the problem is definetly fixed in the C10 charge id like to change mine)
[Nexus 7 General] hoeffel-t:
but revideh

Hi,

I hope they fix all the problems with the c10 devices.

Only when there are no more hardware problems I will buy a Nexus 7 a second time.

At the moment I´m happy to have gotten my money back.

Best regards

Tobias

Happy happy... Joy joy...

Been a lurker for a while... feel I need to help the folks.

I had 2 C70's from Google Play store, returned both.

Both had screen lift, one had all screws missing on left side of screen, the other had them.

The first's screen's protective coat wore off/dissolved.

Both would not charge via USB car charger while the unit was on and with or without WI-FI (yes I had a 'shorted' cable).

The second's screen was un-responsive on 30% of the right side when cold or randomly.

Both had the 'black line flash' in Crome or other apps.

I now have a C90 from my local retailer and a K firmware.

Very slight screenlift occured during the first charge, it now has settle in and not lifting after 2 weeks.

The battery will charge while on and using wi-fi.

I use a screen protector from when I opened the box..not taking any chances.

The newest firmware/os update has increased the performance very nicely!

"Black Line Flash" issue is still around...oh well...
[Nexus 7 General] thomase00:
So, does anyone have a C10O yet?
[Nexus 7 General] ericdjobs:
I really don't think the "black line flash" is a hardware defect.

I get the occasionally on my brand spanking new C90K and it's only in very specific applications, and very rarely (yes, like chrome). Chrome has way bigger issues on my HTC Amaze,,, garbled displays galore etc.

Just saying, I've seen this happen once in a blue moon since I got it.

Also, I've had quite a few times now where I had the "Sleep of death", which I think was app-induced, did some house cleaning and hopefully I won't see any more of those. It sucks because it doesn't seem like you get any useful logs when that happens, I'll have to try and use that app that pipes logcat directly through UDP. It also has very minor screen lift on the left side (you can see the very edge of the screen raising above ever so slightly.)

I'm not really worried, though, because I'm returning it on the 26th (bought on the 12th from staples!) to prepare for a shiny new 32gb :D
[Nexus 7 General] krenaud:
CAO

Yes. I bought a CAO device in Sweden last week. I haven't noticed any of the problems reported here yet. Only problem so far is that my Netgear WNDR3800 router hangs when the N7 has been in sleep mode for a while, so I've been forced to put my old WRT54G router into use again.
[Nexus 7 General] BTr_RJ:
I have a C90, the only thing i noticed so far is a very slightly lift on the left side...the screen is at the same level as the gray and the right side is a thing lower...i have no flickies, washed colors or whatever...i'm very satisfied with it.

Edit: I opened mine to fix the screen lift, but i noticed that 3 screws are missing... wtf?!? Is there a way to buy these screws? How is the other way u´re using to fix the screen lift?

i have c90 and the only problem is the screen separation ( a small one ).now a have a question.if i use a cover instead returning to service and wait 2-3 weeks for another one with the same problem ( if i'm lucky ) will make things worst ? i like this one:

the price is about 100$, but i will try to homemade one since my grandfather is (WAS) shoemaker.80 years old and some eye problems...but i'l try
[Nexus 7 General] Omar04:
I returned my C70 after 10 days because screen lifted on left side more than usual after a slight lift got a C80 and have a slight lift on left side right out of the box thank god after the exchange got 15 days more on Walmart to return it will wait for the 32GB if it arrive to Walmart before November 6th :D

I notice that in the first one C70 color were wash out in the new C80 colors are bright and speaker louder. Also no lag as the C70 suffered for. (4.1.2)
[Nexus 7 General] vorcers:
Does someone else recognizes the screen lift on this Video?

https://www.youtube.com/watch?v=Atc1cLs8a4c

Serial C9O is at 00:40 and the screen lift at 0:43 and maybe at 0:53.
[Nexus 7 General] belgian pie:
What's a C90 or any Cxx?

Because no where in my serial I can see Cxx ...

---------- Post added at 08:00 PM ---------- Previous post was at 07:38 PM ----------

C90 ... no problems with display yet ... about 1 month now
[Nexus 7 General] FallN:
:D:D:D

Definitely screen lift.
[Nexus 7 General] jahmgwapo:
Do you think it is more safer to buy now to prevent those defects?
[Nexus 7 General] phonic:
Some people with C60s (first release) have had issues and some people didn't. The same has held true for C70s, C80s, C90s and CA0s.

There is no "perfect" release number.

So buy a tablet, ignore the CXX, check it out, and if you like it - keep it. If not - exchange/return it until you get one you do like.
[Nexus 7 General] mrnovanova:
A totally agree I sent my N7 to nexus got a new one back one week later and it's a C60 and its perfect.
[Nexus 7 General] SPreston2001:
I agree as well. People think newer is better while the fact is nothing has changed in terms of production lol. Just buy the tablet and be happy with it.
[Nexus 7 General] DarthGeorge:
c80 here and flawless. At least to this point
[Nexus 7 General] moe3754:
I have the C90 from Sam's Club and everything is perfect, as for any problems I really do not care because with my membership I get a extra year of warranty and so I can exchange it for a new one if it ever shows any problems.
[Nexus 7 General] phonic:
Not exactly.

Sams Club only offers a 30-day return/exchange policy on tablets.

However, I believe that they offer an extra year of warranty ONLY if you use your Sams Club credit card to make the purchase. But that is generally AFTER the manufacturer's warranty is over and many other credit cards offer a similar service.

But what that means is, from Day 31 until Day 366, you would need to deal with Asus. And you couldn't return it it to the store.
[Nexus 7 General] jayochs:
loving my two c90s. no screen lift, seems great.
[Nexus 7 General] Huey85:
Both my 16gb (C70) and 32gb (CA0) are both perfect. No screen lift issues or dead pixels or creaking. Both direct from the PlayStore
[Nexus 7 General] littld:
I have a C90 seems perfect but... occasionally I get a slight vertical line flicker. Not always in the same place.
[Nexus 7 General] jayochs:
i've noticed this and thought it was my eyes! I've noticed it in the nav bar and on the screen randomly for a milisecond. weird! probably software.
[Nexus 7 General] Cryingmoose:
My C70 is perfect. Although I did return my first 2 N7's (didn't check the CXX, and but they would have likely been C60 & C70)
[Nexus 7 General] moe3754:
Yes exactly I have the Sam's club Advantage Plus membership that with the $18.00 purchase of the two year warranty I get a third year for free so yes I have three years on my Nexus 7 warranty! And I used my Chase Master card to purchase my Nexus 7 so your information about needing to use their credit card is wrong. As for returns I have returned a Defective Vizio TV to Sam's after a year all I needed was the sales slip so yes I can return it to Sam's if it is defective. You really need to research before you say something. Just like how all the people on this forum hound new people about the search maybe you should use the same advice!!! That is why I pay the $100.00 a year for my advantage plus it gives you much more than the regular membership at Sam's.
[Nexus 7 General] phonic:
Hahaha. I love it when people want to talk about facts and research, and yet cite incorrect information.

There is a big difference between a WARRANTY and a RETURN.

Per Sam's Club's website:

http://help.samsclub.com/app/answer...2LzEvdGltZS8xMzUyNTc0MzkxL3NpZC91Q05LQ1hhbA==

"Cell phones, tablets, e-readers and GPS must be returned within thirty (30) days of the original purchase and with a receipt."

So no, you can not just walk into the store a year later with your receipt and return you tablet. They also tightened down their policy on TVs to 90 days since too many people were taking advantage of it. Sure, you might have an extended warranty, and they will repair or replace it for you, but that is different then just bringing it back for a refund.
[Nexus 7 General] luckylui:
C60K Model over here. No problems at all! Love it so far. Very happy with the purchase.

#Galaxy Nexus HSPA+
[Nexus 7 General] AlleN7:
Awww I have a C80. Was there anything wrong with that batch? I dont have the latest make now :(
[Nexus 7 General] Geopaul88:
That sounds cool.
[Nexus 7 General] guitarofozz:
Yeah the c80 were the worst batch. Damn. That sucks man.
[Nexus 7 General] mrsatan:
That is bunk. I had a c70 with nasty screen lift and so far my c80 is flawless. The c80 was the largest batch so that would artificially make it seem worse. Until people show that it actually has a flawed display number I don't believe it. Screen lift is an issue but not all have it.
[Nexus 7 General] AZImmortal:
Can someone with a C9O test the multitouch issue mentioned here?

http://xdaforums.com/showthread.php?t=1789450

Basically, you lay the tablet on top of an ungrounded surface (a wooden table or cardboard box is fine) without plugging anything into it, and then using a multitouch testing app, you cross the axes for the touch points like seen in the video.
[Nexus 7 General] AndDiSa:
In that case I should be very lucky :)
[Nexus 7 General] Warren_Orange:
Every batch below C90 is garbage and should be thrown in the trash :rolleyes:
[Nexus 7 General] Kueber:
Issues are still present with my C9O (finally realized that it's actually an "O" and not a "0" :D), that's weird. Never realized that. But using those gestures in google maps works fine - that's likely why I never noticed it.

I see the demand of opening it, lol. I'll look into doing a detailed 'documentary' when I got some time.
[Nexus 7 General] AlleN7:
First my One S gets banned from T-Mobile due to the seller scamming me and now my Nexus 7 is garbage. I've had enough of electronics.
[Nexus 7 General] iamhcg:
Just for your information, Nexus 7 has been sold here in Taiwan this month. All begin with the SSN C9O. I've been following some posts in local forum. Here's what I know.

Yes, there are still screen liftings in C9O. For now, mostly are minor. No one knows how seriously it'd get since Nexus 7's only out for a week. Let's wait and see. But I won't say the problem is gone forever after C9O.

Second, I've heard one case of screen unresponsiveness. Still, no one knows how many or less cases will that be after, say, a month.

Overall, my knowledge is that the issues on the previous productions can still be found in some of the C9Os, but maybe signifcantly less.

By the way, the build number in C9O is "JRO03S". That's a confirmation.
[Nexus 7 General] veeman:
We should all just go back to hunting and gathering. :rolleyes:
[Nexus 7 General] zedlor:
Is there no way to guarantee getting a C90? I will hopefully be returning mine to eBuyer because of slight screen separation and popping speakers, but I don't want to get offloaded with another C70 if I'm honest :/
[Nexus 7 General] shook187:
Good luck actually getting a return from the ebay purchase.
[Nexus 7 General] kikikaka:
I have a C8O, it also has some of problems mentioned in this N7 forum, although it is not serious .. If anybody want to buy Nexus 7, I don't recommend to buy (at least at this moment). I would suggest wait until the problems are solved..

I guess Asus wants to reduce cost (using cheap components ?), and quickly get them to the market, the design may have problem, and also the QC is no good.

I hope it won't have the same fate as N1, there is hardware problem (eg, touch panel), but it will never be fixed.
[Nexus 7 General] julianlyle:
Goddang it. :(

[Nexus 7 General] zedlor:
Haha, eBuyer is an English website, not eBay :p
[Nexus 7 General] iamhcg:
Another thing, what's really bothering many Nexus 7 owners in Taiwan is when the screen goes into sleep mode, it won't wake. Personally, I believe this can be solved by flashing costume ROMs. But not all users are comfortable and familiar with rooting and flashing. This combined with the screen listing issue and some of them low volume of speakers, you can say that there are going to be quite a few RMA going on here.

Well, no perfect world!

BTW, it makes me wonder what has been done to the "JRO03S" build cuz there is no sleeping-dead situation in previous build.
[Nexus 7 General] tntgdh:
I just opened mine and shoot some pictures of the internal stickers. Couldn't find my model on any of them....crap.
[Nexus 7 General] wontstoptalking:
Hey, I bought one from the google store on Friday, do you think I'll get a c9o? I know it's impossible to be sure, but does anyone know what's most likely to happen?
[Nexus 7 General] demandarin:
Chances are slim you won't. They just send out what's available in stock. They still sending out C7 models. I have one of the original models(can't remwber, boughtitfrom ggogle play when it first came out). I asked for a replacement and was hoping to receive a C8(latest at that time). Nope, they sent me a c7 model whose speakers were busted and package looked like it was opened. Seal was broken. Soil just going to keep my original unit for a while until further down the road when issues more than likely to be fixed. I have minor screen lift(which I don't notice anymore because I keep my N7 in a case) and speaker crackles a lil. Other than that, my original unit works fine. So ill be mailing them back the replacement they sent me.

No guareentee to get latest model on an RMA return. Plus you can't request it also. Its whatever they send you that they have in stock for replacements. They still have tons of previous models to sell before the C9 models sell in large numbers.
[Nexus 7 General] gogol:
I got C80 and I don't have any issues.

No screen lift, no washed out, perfect speakers,...
[Nexus 7 General] julianlyle:
OP, did the N7 develop any issues during these few days of use? I might get this C9O.
[Nexus 7 General] Beards:
All this talk of C80 & 90; I picked my N7 up from Tesco UK last Sunday (9th Sep) and immediately noticed it's a C70 model, so they are still selling older stock.

Personally I have zero problems with the device.

My message to those who get an earlier model like I did, don't assume it will be inferior.

I could change mine for a C80/90 and end up with a load of crud!
[Nexus 7 General] Visa Declined:
Quoted for truth.

My roommate has a C70 and I have a C80 and both are excellent, no screen lift, no visible dead/stuck pixels. I check them for problems frequently since I started reading these forums.
[Nexus 7 General] burger30:
C90

Just Bought one yesterday at Staples In Canada

and received a c90 , not seeing any defects at all.

still testing though....
[Nexus 7 General] espionage724:
If you want to buy me a C9O with your own money, I'll gladly dispose of my C7O :p
[Nexus 7 General] denmoe:
I bought a C90 today in Bochum (Germany) and did not recognize any problems mentioned for the N7.
[Nexus 7 General] Evil_enc:
At Saturn or Media Markt?
[Nexus 7 General] denmoe:
Media Markt. It was the last one they had.

Well i guess i was wrong considering my N7 has not any issues. After making the test where you look from the right to the left side i can see my screen lifting a bit on the left side. That sucks :(
[Nexus 7 General] aweskelo:
any models with the screen flicker? my launch day unit has it badly
[Nexus 7 General] julianlyle:
Would you guys with a C9O tell us if the units are missing screws or other relevant stuff (developing issues during use, screen raise after playing)? Thanks in advance.
[Nexus 7 General] denmoe:
I can`t tell anything about missing screws and other stuff on the inside. I don`t feel comfortable opening up that device because their might be a possibility of losing warranty.

I didn`t notice any other flaws on my N7 yet. That makes the whole situation even more annoying because it is such an awesome device.
[Nexus 7 General] julianlyle:
You won't void warranty if you take the cover out. I even repositioned some screws, saw that the lift was still there and returned it with no problems.
[Nexus 7 General] SPreston2001:
Losing warranty?? Lol dude the cover is removable and doesn't have any security stickers or anything. Taking the cover off is completely undetectable and safe.
[Nexus 7 General] buggatti:
can someone post picture on the c90 turned on. I want to see if the screen color and quality has been increased. I have the fist bath of the nexus and I want to know what am I missing or is the screen is the same

Thanks a lot.
[Nexus 7 General] espionage724:
It's not unheard of for devices to loose warranty because you opened it...
[Nexus 7 General] julianlyle:
It won't happen with the N7.
[Nexus 7 General] espionage724:
I know. Just some people seem to think most or all devices are like this, and seemed surprised when people ask this.
[Nexus 7 General] kikikaka:
As far as I know C8O means it is manufactured in August. I guess even you got a C8O, there is early C8O and late C8O. Maybe they changed something at late Aug ...

If it works well, don't mess with it...just MHO...
[Nexus 7 General] ÜBER™:
Dont have this issue with my c7O ?
[Nexus 7 General] Solange82200:
I at one point in my exchanges had one nexus 7 that was super bright as well, I couldn't read in the dark comfortably. It also had a light bleed spot. Can you please try the app screen bleed tester and put it on highest brightness and see if it has screen bleed?
[Nexus 7 General] buggatti:
mine is c60. does that batch exists and what are its problems
[Nexus 7 General] Solange82200:
The list of possible problems for any batch (yours is from an early batch in june) are screen lift, dead pixels, light bleed, touch screen problem (requires a very specific set of circumstances to recreate, so many people won't know they have it till they test it accordingly) etc. Don't worry so much about your model number if you don't see any of these things. There are tablets from all the batches that are fine, so your model number shouldn't automatically be cause for worry
[Nexus 7 General] vorcers:
Nice to know, i have an C8O with screen lift, and I was thinking about to get an C9O. I think every Nexus 7 can get a screenlift. Maybe sooner or later every device gets this issue.
[Nexus 7 General] xmoo:
Seems like "S" is on some of the C90.
[Nexus 7 General] moyajaya:
Is c90 the latest batch with the least defects or is there any better serial number?

I'm worried about getting a defective unit as I won't be able to return it easily from my country: morocco.

Is there a quick way for him to spot those mentioned defects easily? Him being a non tech savvy doesn't help either.

I'd appreciate your help!
[Nexus 7 General] mintvilla:
I got mine from Tesco's, first one i got from tesco direct, was a c60, was perfect in every way, except the screen would randomly go unresponsive, so took it back and they gave me a c70, this was terrible it had quite bad screen lifting, i did take the back off, because i had seen that on the newer c80's they had removed a screw on the left hand side, however when i opened it up, there was only 1 screw on the left hand side, the rest had been removed anyway.

So i took that back and was given a c80, this time i opened it up in store, as i couldnt be bothered going home and coming back, but alas, it was perfect and has been perfect ever since, Zero issues ever since. (did install CM10 on it btw, so not commenting on software but hardware was fine)

Also for anyone returning a device for a new one, when you get the new device, if you sign up for a new email account you can get another £15 voucher (since its a new tablet) , go into the store, spend the £15 ($25) then wipe the device, when you go through 1st time install, put in your normal gmail account, but then when you go to the play store, hit the option button and select accounts, add a second account of the new gmail you just made, but then only get it to sync apps, then all those apps you had just bought will appear as purchased, therefore you can use both accounts, with out it being annoying that you have multible accounts on the device. (also its abit of compensation for google messing you around, trips to the store, making calls to premium rate numbers etc for returning the device)
[Nexus 7 General] TheChaoticLlama:
My brothers C90 is nearly identical to my C80 in the UK. Build quality seems better, my screen is spongy near the volume buttons but that's about it. Using that colour chart they look exactly the same.
[Nexus 7 General] killer23d:
I exchanged my C6O due to it having a very slight screen lift on the bottom left, I got a C9O.

Compare to the C6O, the C9O does not have any screen lift. I could feel the silver edge on all sides, not like the C6O where you could feel the edge of the glass where it lifts.

Screen wise, I *think* the screen is slightly brighter, and colors are slightly more pale. The C6O is more saturated and I like the C9O more. Have a look at the image below. It is taken with my phone, with auto-brightness in a room with 1 light. It is not bad when I load the image here http://www.pbase.com/gbc/image/48396088

I am happy with my C9O and see how it will go. The difference between C6O and C9O? Too insignificant to make a fuss about it unless it already has issues.
[Nexus 7 General] julianlyle:
So no one here with a C9OK had any issues with it so far?

Can someone please check how many screws does it have on the left side?
[Nexus 7 General] airmaxx23:
I just got my wife's 2nd replacement and it was a C60K, the whole left side of the screen has a 1/4" strip running down it where the colors are faded real bad. I'm really starting to get frustrated, it took me 5 replacements to get a good device for myself and now we're on the 3rd for her. The sad thing is that we were considering getting a bunch of these as gifts for Christmas time, I think we'll be going a different route now.
[Nexus 7 General] julianlyle:
As far as I know this thread is dedicated to the C9OK model.
[Nexus 7 General] julianlyle:
Anyone?
[Nexus 7 General] sluma:
I just picked up the C9OK model from London Drugs in Calgary Canada. Screen issue is still there but it's not as squishy. It looks more like a bump that feels very solid. it sucks that it's still there but at lest when I press on it it does not regress in. It is running build number JRO03S
[Nexus 7 General] kaveman3:
First one I got had screen "blemish" issues. Not sure which model it was. I've got a replacement C7 and have had no issues...

Just another $.02
[Nexus 7 General] kryptoniteguy:
My build is JRO03D, anyone know what that is? Oklahoma purchase here..
[Nexus 7 General] rockky:
Jesus does ANYBODY in manufacturing bother to look at these things?
[Nexus 7 General] julianlyle:
I've heard there are flush screens on C9OK, can someone or the OP confirm?
[Nexus 7 General] sluma:
I stated a few posts back that mine was not flush :)
[Nexus 7 General] olivercervera:
I've just bought a brand new Nexus 7 16GB in Italy. It's a Italian version, and it's C90. Just perfect :D
[Nexus 7 General] julianlyle:
I already thanked you for your feedback, but I've heard there are more cases of flush screen on this model (C9OK) than on any other.

I know the lifted screen problem persists, but hopefully they're getting rid of the problem.

No lifted screen present on your unit? Nice, can't wait to get a C9OK here in Spain. Hopefully by next week on mediamarkt.
