[Q] Got a C5O tablet under warranty replacement - Nexus 7 Q&A, Help & Troubleshooting

I got a C5O Nexus 7 after a warranty replacement for a faulty touchscreen. This one doesn't have any screen lift and seems ok, but I still have the multitouch screen problem when crossing the vertices. Wondering if I should just wait it out and see if an update fixes it, or RMA again. Anybody else have a C5O?

I thought I was seeing things, so I used a magnifying glass and I too have a C5O. I bought it used last night and no screen lift on mine either.

So i sent my nexus in for repair

it arrived yesterday at htc repair and ive been watching the repair tracking site. i had some pixel problems, like a quarter of my screen was darkened grey.
Keep in mind my phones bootloader unlocked, rooted, haha and i sent it in as is running the latest miui. Why? idno.
Anyways. I just checked the repair site and it says:
Ticket Information
Status: We are repairing your phone.
Service Type: Repair
Issue Description: top screen is darker that the rest of the device
I havent approved to pay for any repairs for an out of warranty phone. So i guess im off the hook right? I think im about to prove that htc repair people dont give a F***!
THought id share..
Uhhh, we have known this for a year now. It has been proven time and time again that HTC will warranty repair hardware defects, despite an unlocked bootloader.
This is nothing new or surprising.
Did someone has problems with the multi-touch screen: lags, do not respond or random reactions ...even when having a call ?
the solution for now is to push "shutdown button" and it seems to reinitialize the sensors for the screen ... isn't it weird ? It occurs 40% of the time ...
The menu for reinitialize sensors/calibration do not exist (for HTC Legend/Hero you can re-calibrate the sensors).
Do you have same problems ?
I will send it for repair soon...
im having the same problem, ive had it for a long time now, ive gone threw 20 Roms. so i know its not software related, or is it something the devs are over looking??
weird thing ....do Googlers have same problem when demonstrating navigation/goggles/phone calls/voice recognitions .....or do we fall on bad series ???
definitely hardware problem or something no-one has been aware of ....?

Sometimes it's worse than others, I think if the phone is running something pretty intense it happens more often. Otherwise, no, there's no calibration. Calibration doesn't make sense on a capacitive screen.
The touch screen issues have been known since the beginning, and the solution of quickly turning the screen off and on has been known for just as long.
It's part of the hardware, and most if not all Nexus owners experience it once in a while.
Getting a warranty replacement for that will not fix anything, it is a flaw in the hardware design.
Good thing to know that...but really weird for such a device...they probably think about it when starting/choosing next nexus.... ;-)

I'm curious whether they'll return it with a relocked bootloader and stock ROM
i've noticed that the only time i have touchscreen response issues is when i use my N1 without a case on it and it seems to be because some of my fingers touch or get near the edges of the screen glass. i have a silicone slip on case and when its on the phone it prevents me from touching the glass accidentally at the edges and i never experience any response problems when its on the phone. just my 2c.

yeah that would annoy the crap outta me as well, glad mine does not exhibit this problem.
i'd love to guesstimate how old mine is but i'm the second owner, it might be possible that they fixed this hardware issue in later build revisions or it could just be a random problem with the touchscreen/module, some do it and some don't idk.

was it amoled or slcd though lol
i have to make the call when i get up. today my usb port was gone from the phone when i went to plug it in tonight. i never used to have the screen issue, it slowly started happening and now it happens all the time, i lay it flat in my hand and i hit a button on screen and my menu pops up etc.
nice to see a recent time frame though, i'm dreading going without my phone and having a dumbphone replacement. would love to know if it was amoled or slcd you got back though, thats my one worry

[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"

Mine got the creek sound after 3 months of use and lifting...
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.

Touchscreen dead strip!

I've noticed just today that there's a dead strip on the touch screen. It didn't do this yesterday. The Nexus 4 was dropped once from 2 feet high, but that was almost a month ago and everything worked fine until now.
The screen still looks beautiful, no dead pixels, no cracks, and the phone is in a protective case with a screen protector.
It seems to me that the digitiser crapped out, but I'm not sure why it happened so randomly.
A funny thing though is that when I drag something fast across the strip it works. And sometimes it'll recognise a touch as a long touch or two-fingered touch along the strip. Weird.
I attached a few touch test photos to show the issue.
Hopefully there's a fix. Has anyone else had this problem? And if you had to send it back to Google, was something like this covered under warranty? What should I do?

You can try to replace the screen yourself or tell LG/Google to send a replacement via RMA. They have parts floating around Ebay
How risky/costly is it to replace it myself? And does anyone know if it's covered under warranty? Cause if is, it'll be cheaper just to get a replacement from Google.
Are there other ways to check if it is indeed the digitiser? I've seen that sometimes touch screen problems are software related. And if that's the case, it'll be easy to fix.

And .... Out of curiosity, what does cause a digitiser to fail without the screen actually breaking?

Depends. If you follow the instruction properly, it works well. If you screw up, then Google/LG wont be able to help. A lot of people have done it and succeeded. There are great articles on the web. The price of a digitizer would be about $50-70. I MAY BE WRONG WITH THE PRICING.

In most cases no. Because it worked well and suddenly stopped working. Thus Google would say that its your fault. If you are somehow able to convince the Reps that it wasn't your fault, then there is some hope. I

One way is to remove it and put it to a tester or another motherboard and see if it works. But that takes a lot of time and money,

Anything. The phone might have overheaten to the point that it flashed a certain section of a digitizer. It may also be a battery problem that escalated. If you feel that it's software problem, flash a ROM a see if it works.
IMHO You should send it to LG and get it fixed for about $140~.
This problem should be covered under warranty. If you honestly haven't done anything to cause this damage. (I'm also clueless as to what a user could do themselves to make just one section of the digitizer stop working)
Then lasting 5 months or less would not be considered reasonable and you should be entitled to a replacement.
Remember it is down to the retailer to prove that you caused any damage.
And if you honestly did nothing and it just crapped out on you then you should have nothing to fear in sending it back for a warranty replacement

That happen to my iphone when it got water damage. But if you did not do anything wrong, it should be covered by warranty.
Ditto

I did an RMA explaining everything like I said above. I got my Nexus 4 replaced by Google, and they didn't charge me anything. New Nexus 4 works fine with no issues - I've been using it since May.

Same bug here in Italy where I'm living now even if the the phone was bought last year on UK Play store. Problem is Google rep wrote me RMA can take place only in UK or any other county where N4 was originally available on Play store i.e. NOT Italy.
Does anybody know of a workaround to get the RMA here?
Thanks

Yeah, I think the overheating might have been what happened to mine. I was using a blackberry charger and I think it might have overheated my battery and fried a strip of my digitizer.
Even i have got the same problem, i dont know who bumped this old thread, but please guide me to for a low cost workaround for my situation
No drop or glass break.. Dead pixel just one..
Hi,
Anybody found the reason for the issue, i too got the same issue; a dead strip exactly in the middle of the screen, My warranty is over already, so anyone has work around for this??

This looks like a dead thread, but Ill take a punt. I dusted my old Nexus 4 off the other day, which had exactly the same issue with the dead strip on the digitiser. I had tried replacing the screen and digitiser (I have up trying to get the original screen off the original digitiser). The issue remained, so I tried a full factory reset, but that also didn't work. I am now wondering if I should get a cheap motherboard, or try flashing the stock ROM again. Has anyone else had any luck with either?

[Q] touch issues

I have a NST with glowlight and i have touch issues quite often... when using the keyboard when i touch backspace it touches "h".. when i touch space .. it touches b ... does anyone have these screen issues? it's like phantom touches.. i takes me 5mins to type something
This is a known issue. I just received mine in the mail and it had issues. I found you can clean it and it may help. But for me, since it is brand new, I just had them ship out a new one. If you are not under warranty, I actually just did a factory restore and it stemmed to have helped a bit.

ok thx. It's brand new for me also... not even 1 month... do i need to ship back my nook to get a replacement? i bought from ebay... i need to contact who to report the issue? I read when they give u a replacement, they you a refurbished one?
edit: hmmm so this issue is faulty hardware? or it's just cleaniness? and it will happen sooner or later on any nook? will a cover help?

Nook touch screens use infra-red sensors/emitters located around the edges of the screen. If the transparent plastic sandwiched between the screen and the bezel gets dusty, it can cause problems.

so it's not really a hardware fault but it's because of dirt?? any cover case that can protect against such scenarios? how do i clean it?
I think there are two scenarios (perhaps more). Faulty hardware in which the infra red sensors do not function correctly or dirt/ dust impeding their ability to function. One always hopes for the latter.
The reset I did only helped for about an hour.
First try to clean it.
Since you got it off eBay, start by contacting the seller. Ask the person if it is still under warranty.
Then, contact 1800thebook to get a replacement. If it is not under warranty, I am not sure what your options are. EBay and electronics is always a gamble. Sorry.

Go forth and work toward your salvation with diligence.
ok thx,... i have tried cleaning it up but it helps for a few seconds but then it gets freaky at times.. it's a pain to type! do you guys ever take notes with it??? it's impossible...
i don't think it's a hardware issue since the first 2 weeks it works with no problems... i was keeping it in the box while not in use... since i started not keeping it in its box.. i am getting these touch issues... so seems related to dust...
will i need to send back my nook to get a replacement... sounds pretty annoying to do so.. shipping is damn expensive
sidenote: looking at the edge of the nook, i see shiny particles... is this normal or is this dust?
i can't even type my wifi password anymore... every button i touch also "ghost" touch the corresponding middle button.. e.g. when i press d, i get dg ... how do i clean that damn thing? where do i need to clean exactly?? i am cleaning the edge.. does not seem to work.. sometimes it seems ok, then 2 secs later it gets messed up again
Cleaning the screen is a different reason to normal screens. Normally you just want the greasy finger prints off etc. However thats for a resistive or capacitve based touchscreen. NST/NSTG touchscreen works on an infrared array running along the edges ABOVE the screen rather than a stuck on touchscreen so as not to affect the contrast in sunlight.
This means a piece of particulate matter on the screen will affect the touch sensor.
If its confused sometimes it won't work at all! The worst environment to ever take your NST is to a sandy beach, really don't do it.
Personally I use a air duster (compressed air can) to get those pesky bits out of the edges.
When not using NST keep face down to keep out bits of crap or keep in a case..

Replaced H918 display, now flickers very noticeably

I have two H918s. A while back, I broke the screen on one, which is why I bought the second. Today, I did the repair on the first using a replacement display (which came complete with a frame). Powering it on after the repair, I notice significant screen flicker that makes the device unusable. Is this something others have encountered after doing a repair? Or did I just buy a faulty screen?
Edit: A few hours later, the flickering stopped completely. Don't know what it was, but it's all good now. Thanks.
Where did you got the screen to buy?
