C90 - Nexus 7 Q&A, Help & Troubleshooting

What are defects still present on the C90. Ive looked around and all the model numbers are confusing me. I know the C90 is the latest model and would like to know what issues it has. Thanks in advance.

Bear in mind that it's not necessarily a product revision, but rather a designation of the month of production. From what I've seen, C90 has the same hardware defects, such as screen separation, that we've seen in previous months.

After returning 2 c80s my c90 is flawless. Might be a coincidence.... I'll never know for sure.

Happy now...
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...

My original Nexus 7 was a C70 with horrible screen lift and screen dimming issues. It was replaced in late August with a C70 (both from Google) and the second C70 is flawless.

Who isn't going to RMA due to screen raise?

Who isn't going to send their nexus 7 in for exchange / repair ? I would probably have never noticed the screen issue if I wasnt reading the defect threads. I bet if you look hard enough you can find something wrong with anything. Right now the only issue is a slight raise on the left side on mine. There is no light bleed and no dead pixels or ghosting. I feel if I sent mine in and waited for however long it takes I'll get one back where the screen raise is fine and have a new issue like light bleed and dead pixels...

Have you checked your screws?

Yes many have concluded it as a temporary fix

Lol how do people find this stuff mines is barely raised on the left side not bad enough for me to take apart and tighten the screws.
I'm not doing an exchange I love this thing and not ready to part.

I checked my screws and found that they were loose and tightened them up, screen still barely sits above but solved the creak. I have 3 more weeks to tinker with it, my Gamestop said i can return it once the next batch comes in but if this fixed it i won't exchange it.
Yeah I'm not planning on returning it either. I have seen some videos that have a MAJOR raise on the screen. Mine is just a little bit and can easily be pushed back down if I want to. Other than that the tablet is perfect and I don't want to send it back and maybe get one with more dead pixels (only noticed one but et normal viewing distance I can't see its there) or ghosting or something else.
I do recommend you keep an eye on it and make sure not doesn't get any worse. I doubt it will, however I will be exchanging it if it does.

I think everyone's expectations for a $200 dollar tablet are too high.
I am perfectly happy with mine. I have a little screen raise, but haven't noticed any creaks. I will use it until something significantly better comes out, then i'll spend another 200 to upgrade it.
Phones with comparable specs (albeit a smaller screen) are in the ~$400 range (gnex).
Mine was fine for the first 5 days, but has now started to lift. It sounds like double-sided tape coming unstuck. It's only raised about 0.5mm above the frame on the left hand side though, so I don't intend to return it unless it gets a lot worse, or it begins to affect other things (e.g. dust getting in, or digitiser playing up).
May yet return mine for ghosting, though doing a full discharge of the battery MAY have cured that issue (fingers crossed).
Why can't I get through Googles own support site to do a rma on my Google device? Wtf
Because everyone and there mother has flooded them for RMAs :/

Im thinking about sending my nexus 7 because of a yellowish tint on one of the corners when viewing pure black. But I am afraid of getting one with worse issues like the raised bezel or dead pixels.

If I only had the slight screen rise I would probably keep it, but I have a creak on the right that is loud and driving me nuts. Sadly, everything else seems perfect - hopefully my next one will be truly flawless...
I'm not. My Nexus 7 looks very well made, and in perfect shape. I've had it for 24 hours.
Is their support 24 hours? I've been busy and finally called. I've been on hold for about 10 minutes and it seems like they're open...
Yea I wasn't going to originally but after the screwdriver fix did nothing, and its basically like a creaky teeter totter on the left and right sides, I decided I should probably RMA. I love the tablet tho. I've used it A LOT since it arrived. It's amazing.
I have a very slight screen raise issue and I have requested to get a replacement, and depending on the condition of the replacement I'll either keep the new 1 or keep the old 1.

You can do that? I just figured Google would force you to ship the first one back, even if the second one was worse...
Keeping mine, no reason to return for such a silly non issue. Doesn't effect the use of the tablet at all.

Me, because both of my Nexus 7s are free of this, or any defects.
Same here. My left side of the screen sticks up a tiny bit, I'm waiting for a replacement but if the next one is worse ill just keep this one and try the washer fix or live with it. I still think it's a great tablet, especially for the price. I'll take this over an ipad costing hundreds more any day.

[Q] Should I return my N7 32gb? (Screen lift)

Hi all
I bought the new nexus 7(c90) 32gb a few days ago from PC world along with the 2 year guarantee. Out of the box it was working perfectly and I began setting it up as you do .
Anyways after around 10 mins of using it a tiny flake of the silver plastic bezel felt loose and then fell off so I have this 4mm black "scrape" on the corner of my N7's bezel but as this is so small (I will try to include a pic) I am just putting it down as wear and tear
However here is my bigger issue. After reading how many 8gb/16gb N7's had the dreadful screen lift I decided to check mine. It seems that the middle of the left side of the screen is higher than the right side and does not sit flush with the bezel however it's barely sitting a width of a hair above it. I can run my nail from the middle of the screen to the right and feel the bezel is higher than the screen however when I do the same to the left side my nail simply falls off. If I hold my N7 horizontally and look down at it , the left side is higher than the right as the bezel cannot be seen towards the middle of the screen. If you look at the left side you can sort of see the screen bulging out by the smallest amount and if you push on the screen you can see a very very small amount of screen flex.
I would really appreciate any advice. I asked my parents to buy this as a Bday present me as these N7's are really good value for money and this being my first proper tab I really wanted to flash roms ect but due to the screen lift/bezel issue im not sure what to do. PC world claim to refund or replace any item that develops a fault within 21 days. Spoke to my parents and they tell me if it's that small of an issue I’m just better off leaving it. Yesterday I want to a large shopping centre and tested out some N7's(not sure on gb's) and 2 of the 3 displayed a similar issue however due to the rush I’m not 100% sure. Also tested Tesco’s 16gb and there was no screen lift.
I'm worried that after a while the screen issue may get worse. After some reading last night I read that 32gb's are excluded from this design flaw so Is there a possibility of me owning a faulty one? . Do you think PC world would accept these as "faults?" . If I'd never seen the thread on screen lift then I most likely would have never noticed anything. .
Hope all this makes sense, any questions please ask!
thanks!
I bought one yesterday mate from Currys and I didn't think mine was bad until I compared it against the display model in store today. Mine had a lot of screen lift and I could easily get my finger nail between the screen and the bezel, the quality was poor to say the least.
I took it back today and had a really good chat with the guys at Currys and they were mega helpful. I ended up exchanging it for a new unit and its near on perfect so I'm chuffed to bits.
You won't get close to getting a tablet of this spec for the money. Take it back and get another one.

thanks for the reply. I'm also able to wedge my nail in the gap between the bezel and left side of the screen. I am strongly considering returning it back in the next few days however I'm not sure if they will accept it as the screen lift isn't that noticible initially . Also how did the exchange process go?, did you just get a new boxed replacement or did you ask them to open up a few?.
Cheers

Definitely get it replaced.
-Brought to you by Marino's Nexus 7-
Mine was quite noticeable because even though I hadn't had the tablet a full 24hrs there was already dust and bits gathering down one side of the screen which made it stand out even more. The screen lift was something I could only see getting worse. I actually took the back off for a nosey before I exchanged it and I could see there were missing screws down the side of the bezel which I believe is how Asus are trying to combat the screen lift.
The two guys I spoke with at Currys were obviously in to their gadgets as well and were aware of the quality issues with these tablets and said if I wasn't happy I could have my money back or exchange it for something else, or they said I could try another one and see how I got on. I personally didn't suggest opening them until I found one I was happy with as I appreciate they wouldn't be able to sell them then.
I'm happy with my new one though and I'm really glad I exchanged it.

I took 2 back to tesco both within 48hrs, both suffering screen lift, my 3rd has it ever so slightly, less than 0.25mm but as it's in a case it hasn't got any worse so I'm happy to live with it as is.
So yes take it back as it is a known fault.
Transmitted via Nexus7
I bought one from Staples and after couple of days of use I too found the screen lift on the left side. I finally returned it yesterday morning. Then in the evening I got a new one from Office Depot. So far its free from any defect. I hope it stays that way. Also my new one starts with serial no. CA0K. The one was defective was C90K.

Yes even though there are known issues and we've had bad experiences, don't get clouded in to thinking this isn't a good tablet because it is and I personally think it's well worth the perseverance. I've now got it in an official Asus neoprene flip case and a zagg invisible shield screen protector, looks the dogs

Mine was bought in July and I have just noticed screen lift. I bought it from PC world, what shall I do

Thanks for all the replies!
I will be going in for a replacement tommorrow, I just hope that they will accept it. Like I said before, the screen lift is not very apparent however it is there. If the staff disagree and kick up a fuss that there is no screen lift or the screen lift has no negitive effects then what's the best course of action?
Since buying the N7 and discovering it had screen lift + chipped bezel I don't have the satisfaction of it being "mine",really wanted to flash roms and experiment but the confusion in returning it or not kept me stock :crying: . The N7 I have does not have any light bleed,ghosting and I'm pretty sure the colours of the screen are normal. Should I check this on my replacement N7 when I get it?
Also I'm looking at a N7 starting with C90 right?
Another thought is getting a refund and saving up for a 32gb nexus 10 . Also A N10 would cost me around £200 extra . I initaily went with a nexus7 as it was cheap for the high specs, In my budget and as it is my first android device & tablet allows me to learn & tinker with it with no regret compared to a almost half grand N10. I have also heard on here that many users downsized from a 10" to a 7" . Could anyone shed their opinion?
P.s: I have attached some images
I'm returing mine for black lines , the only thing is I can't find the warranty card . Do I need it ?

I'm so shocked that Google hasn't stepped in to improve the quality on the 32 gig models after all the problems with the 8 and 16. I love Google products but quality must come first not quantity. I used to work for Sony and this would've been totally unacceptable.
Return it and open the replacement right in the store and continue to do that until you get a good one.
Return it right away. The more tablets that get returned because of this "screen lift" the better. Maybe next time they will not repeat the same mistake.

Just an update
Went in and was able to get a replacement N7, Checked this one in the store and it had pretty much no screen lift apart from a very very very slight lift from the left towards the bottom. We also checked another one inc a display model and they were much worse. I also went snooping in various shops to look at the N7 and all of them had some sort of screen lift.
Overall I'm quite happy with the new one, my only complaint is that there is a small amount of backlight bleeding in the bottom left corner if the brightness is set at 100%. If the brightness is on auto or below 50% you cannot really see it unless you are actively looking for it.
I've heard much worse issues with the N7 so I'm happy with this one. Am I right the LED's are only located on the left side of the tablet?
I'd return it again. I've returned 3 and my newest is flawless. there are good units out there, you will find one!

I applied a minimal amount of crazy glue to the affected area months ago, and it's been perfect ever since. Asus sucks, but if you want a 7" Nexus, what can you do?

Opinions Wanted, Slight screen lift:keep or return

So this is the 3rd day i have owned my new Nexus 7 32gb SSN: C90 bought from walmart. Really happy with the device, the first day i had checked it for screen lift and didnt notice any, not saying it wasn't there as it is very likely i didnt even quite know what exactly i was looking for. However, after examining it today, more in admiration of it, i noticed some screen lift on the upper left side (in portrait orientation). I believe this is exactly where mostly everyone else has noticed it. I could tell there was screen lift because when looking at the device from the right side over to the left i am not able to see the bezel where the screen lift is occurring, while from looking from the opposite side i am able to see the bezel completely.
Anyway, what are your guy's opinions? should i return it and exchange for a different one, i checked all of their stock and they are all C90 models, not sure if that matters but i assume they are all from the same production batch.
Hold on to it until a new batch comes in, then exchange it.
If it's bothering you or there is noticeable movement in the screen when you tap that area, then return it.
Ignore all the talk of "batch numbers" there have been issues with every single one of them. Personally, I had a C70 with bad screen lift and it was replaced with a C70 that is perfect.
Its bothering me, but it is only because I know its there, there isn't any noticble flexing in the screen when viewing it normally. Have purple had the screen lift without issues?
Washer fix and move on with your life. I've been through 4 and 50% of them had screen lift. The washer fix works awesome and takes a few seconds. The back is meant to pop off. No big deal.
As for all my swaps.
#1 bricked after flashing a bad boot loader. #2 was stolen. #3 was a loaner that I returned for #4 32gb.
Washer fix works. Or get a case. Boom.

[Q] Are the screen lift issues and touch input issues resolved now?

I had returned my tablet about a month or so ago because of the reocurring screen lift issues that I received with every RMA I did.
I would love to get another nexus device (either the 7 or 10), but wanted to know if the screen lift issues and touch screen input issues where the display would act on it's own accord, had been fully resolved yet before I request one for christmas.
Is there any new faults in the manufacturing process, or have they pretty much all been taken care of?

I just recieved a replacement for my 32g due to dead pixels, but that can happen on any lcd, the new one is perfect, i havent heard of screen lift issues in forever
I sold my 16 gb that had a loose screen and bought a 32 gb. This one doesn't have screen lift at all, but now if you press the back of the tablet, it creeks. Doesn't bother like the screen lift, but it's still a defect I would say.
Bought a CB0k...16 gig, with screen lift. I don't know if I should return it for the 4th time, or just live with it....
Got a new 32gb. After about an hour of use the top of the screen has completely separated from the unit. I'd say that they definitely haven't fixed this problem.
That isnt the "screen lift issue".
Your device got some other fault, which Ive never heard of before. Doubt that is a common problem like the "screen lift issue"

I removed the black foam on the left side and unscrew the 4 screws.
I clip the screen all night and now my screen is perfect.

Nexus 10 yellow blotches on screen
I'm having the exact same problem on a year old nexus 10, that is a central pale yellow brown stain most visible on a white background.
It looks like a nicotine stain as if some heavy smoker had been handling the screen. Initially I thought the screen protector had yellowed so I removed it but no improvement at all.
Have others seen this problem? Any solution?
Not a solution but the problem is down to the individual colour LEDs
Additive colour: red + green = yellow. Yellow + blue = white
Going to bump this thread, I just recently purchased a used Nexus 10 from someone and have this same issue, short of sending this to get repaired (out of warranty) is there any known fixes?
I have looked all over and have not found anything, the only viable thing I found which was Display Control by franciscofranco does not work on the Nexus 10.
Any information would be appreciated.
Screen Yellowing
I've got the same issue of the screen turning a kind of dirty yellow on about 75% of the screen. I bought it on first day of sale release. I think the it's been yellowing for about 2 months or so. Also have gotten a significantly shorter battery life in the last couple of months or so. Thinking of putting in a new battery. Great unit. Getting kind of kludgy though. I have to keep killing apps that start up and run on their own.
Screen burn or whatever
Same happened to my original Nexus 10 after about 6 months. Now the replacement is doing the same, again after about 6 months!
I am wondering, how this could happend. My Nexus is over an year old and I couldn't find a yellow touch on the screan. What is the normal using scenario od your Tablet ?
I have the same problem with my Nexus 10 21 months old. Any solution?
Ive had mine for close to two years now, same issue. I even sent mine to samsung during the warranty period, but they are full on retard. They “updated“ the software then sent it back. They wasted just about 2 months of my time to do that.
I try my hardest to just ignore it nowadays.
Same boat for me.. Yellow tinge right where I see it..
Fine with videos and black background... Not been left on as always had it screen off after a minute of no use...
Just been usual usage over the last two years..I must admit..lots of usage each and everyday but what pisses me off is my TF101 screen which is two years older almost and still OK...
Seems there is no screens around as well as been hunting high and low on the net..
If you have this problem head to the google groups page and post so that others know..
