Yea I agree with you here. Especially some of us who got a really well built over all device. the only thing bugging me right now is the touch thing and if that is proven that it's just a software issue then I'd gladly wait until a fix or go ahead and install CM
[Nexus 7 (2013) Q&A] :
Its probably a kernel problem. And all kernels will have It since they're built off stock. So no matter what ROM you're on you will have the problem.
[Nexus 7 (2013) Q&A] TurboFool:
I came here specifically to ask if anyone was experiencing these issues, so I'm so glad to find this thread. With this many people complaining, it's more likely to get noticed. Typing on Voice is hell on here. I keep accidentally hitting Enter and sending messages when I was trying to backspace and correct an error.
[Nexus 7 (2013) Q&A] Rod3:
I had returned my faulty 32gb device for a new one with no issues. Stayed for 2 days on JWR66 then finally updated to JSS15. I am happy to report that I still have no issues.
[Nexus 7 (2013) Q&A] :
The issues come and go. I took mime off the charger and it didn't have any problems for a couple hours then came back
[Nexus 7 (2013) Q&A] Rod3:
I still have zero issues 4 days after updating.

Just to make sure did you guys use a tool like in the video I just uploaded to make sure you don't have any issues?

[Nexus 7 (2013) Q&A] v3rn:
Well I bought mine from Best Buy on July 26, 14 days is tomorrow so it will be going back. And I'm gonna hold off on buying it again until there is confirmation that this issue is fixed. I'm not going to keep going back and swapping them out until I get one that works.

---------- Post added at 05:27 PM ---------- Previous post was at 05:01 PM ----------

Been chatting with an ASUS rep from their website, and he said that it's definitely a hardware issue and that I would have to send it back to ASUS. I told him I would just return it to Best Buy, and he said that was fine.

I had him look at this thread, as well as the Android bug page. I also had him view multiple youtube videos and he understood exactly what was going on.

He said he would get the info out to those who need to know. And maybe we'll get an update from ASUS about the problem and whether or not it's been fixed so that I can pick up a new device.

Who knows if he will do anything or if he actually knows it's a hardware issue or not. But figured I would let you guys know. We need to start bugging ASUS about the issue and not Google.

I think we need a campaign to start emailing and calling ASUS and letting them understand that it's a pretty widespread issue.
[Nexus 7 (2013) Q&A] :
I'd really like a confirmation as to of its hardware or not... Just got this yesterday and its aggravating me so much. Not too bad but knowing its there on a device I paid a good amount for is bad. I can barely play games or pinch to zoom.
[Nexus 7 (2013) Q&A] Simer03:
Using a multitouch tester, I have the same issue! I wonder if they can patch it?

[Nexus 7 (2013) Q&A] Sud0lit3:
Well I'm going to replace mine today and hopefully if I get one from a good batch I will try it before updating and test for any issues and make a video. then I will try to do an update either later in the night or maybe tomorrow and make a video for that. then maybe once and for all we can decide if it was a software or hardware.

Fingers crossed I'll get a good one this time around.

Thank you very much please do so I can know whether to replace it or not
[Nexus 7 (2013) Q&A] canoo:
Does anyone have a link to a 16GB Nexus 7 (2013) stock image or to instructions on how to create one? I'd gladly create a stock image of JWR66N for anyone wishing to revert back. Pretty pissed off Qualcomm are being dicks about the stock images...

[Nexus 7 (2013) Q&A] :
So on the Google forums there's a thread with many replies to this. Huge issue. But some people are saying replacements fix the issue ? I don't even know what to do this is driving me crazy its not like this thing was 50$ lol
[Nexus 7 (2013) Q&A] delfin2003:
went to best buy today and played around with a demo 16GB unit, no multi touch issues at all running JSS15 plugged in or unplugged. Interesting...I'm still hoping its a software issue even though now it seems to be a little less likely. Gonna still wait till I get closer to my 14 days to swap it out.
[Nexus 7 (2013) Q&A] tsunzilla:
I don't have erratic multitouch issues, but for some reason, at random times... a whole vertical area stripe [about 2 mm] won't detect any touches and will skip when i run my finger over it. But it doesn't happen all the time - It will happen, i hop over to a multitouch test app and it works fine - seems to be randomly disconnecting, and if i tap the multitask button (it's a bit to the left of it in portrait mode) it'll fix itself. Happens plugged in and on battery. Is this something to worry about? What would cause the digitizer to partially not work for a short period of time in a small area strip?
[Nexus 7 (2013) Q&A] :
Hey can you guys send this thread and info to some android news sites? Sent it to droid life and android authority please I want Google to see this issue!
[Nexus 7 (2013) Q&A] metal571:
Just tweeted at Android Authority, we'll see what happens.

Also, doesn't the person who posted the JWR66N image have the 32 GB model? Anyone know if that image will work with the 16 GB?
[Nexus 7 (2013) Q&A] :
Thanks and I don't think so different partition sizes and as far as I know its 32 GB he has
[Nexus 7 (2013) Q&A] Sud0lit3:
So I went and replace my nexus 7 at best buy and the new one has no problems what so ever. BUT I have not updated the device yet. however I will update it to once and for all find out of this is a software or a hardware issue.

Here is the video before the update: http://www.youtube.com/watch?v=k1IdoMWpo4w

Here goes the update...

-----

SORT OF VERIFIED: IT IS THE UPDATE! All the issues immediately returned right after the update.

EDIT: after doing hours more of testing more little things are popping up for example if your hand is touching the back of the device the axis problem goes away but if there is something between it or on a flat surface that isn't grounded it comes back.

RECOMMENDATION: If your device is severely acting up so any ghosting or sensing touches after you stopped touching your device or not a consistent touch definitely get it swapped or RMAed. if the touch issue is minor and only on the axis its a 50/50 if its hardware or software. But I do believe that the software update does have some impact on the touch interface of the device.
[Nexus 7 (2013) Q&A] notmilk:
Does any one have a 16GB JWR66N image??
[Nexus 7 (2013) Q&A] fosser2:
So can anyone else confirm this?
[Nexus 7 (2013) Q&A] JayBomb999:
Your experience mirrors my own. I commend you for documenting this.
[Nexus 7 (2013) Q&A] Sud0lit3:
Thanks I appreciate the kind words, I will upload another video momentarily. It seems I received some unexpected results which will require further testing.
[Nexus 7 (2013) Q&A] metal571:
THIS. If no one else is going to make one, then I will take matters into my own hands, but you guys have to help me out. I don't think I saw any links to videos stating how to make a system dump. Unfortunately, my 16 GB Flo has already been updated since I was unaware of this issue at launch as I think most of us were, so I'll need to RMA to Google first since I bought mine in the Play Store, and then I will take a system dump of the 16 GB JWR66N image for all of you and host it on Dropbox or something for everyone here. Give me a tutorial ahead of time here, I'll probably call Google tomorrow and get mine replaced then unlock the bootloader while still on JWR66N and take no OTAs.
[Nexus 7 (2013) Q&A] rafa3L:
Some reports (most recent one as of right now included) in the Google thread of replacement devices updated to the latest JSS15J and the issue does not occur. https://groups.google.com/a/googlep...2b4-98f0-6d05630c0c25@googleproductforums.com
[Nexus 7 (2013) Q&A] texnnyc:
I was all ready to pull the trigger and get the 32gb model, then all of this stuff raised its ugly head. I'm going to wait it out.

With folks that are having the multi-touch issue - what percentage have unlocked bootloaders? Does re-locking the bootloader affect performance? Just thinking it could be another Qualcomm "gotcha" :(
[Nexus 7 (2013) Q&A] rafa3L:
Unlocked bootloader isn't the problem. I never unlocked and have the problem.
[Nexus 7 (2013) Q&A] Sud0lit3:
It can be simply caused by having your device plugged in. As mentioned in this thread if you test while the device is plugged in either to USB or just charging the issue happens to go away.
[Nexus 7 (2013) Q&A] :
could a rom thats on the old OTA fix the issues? or once you got it youre screwed?
[Nexus 7 (2013) Q&A] Rod3:
This was not my experience.

Had a "perfect" 16 GB running JSS15 and returned for a 32GB. The 32 had horrible touch issues registering multiple touches 10-15 seconds after no longer touching the device. Exchanged the 32 for another new device, no touch issues on JWR66. Updated to JSS15 and still no touch issues. All results confirmed using YAMTT and unplugged.
[Nexus 7 (2013) Q&A] Sud0lit3:
Make sure your device is unplugged and restart your device.

Then do the YAMTT test by aligning it vertically and see if it will start registering erratic touches (make sure to hold your fingers in the same area for 15 seconds atleast) along with try dragging while vertically aligned slowly too.

I'm legitimately curious to see :confused:
[Nexus 7 (2013) Q&A] Rod3:
Dude, trust me, I don't have the issue. Doing what you just mentioned on my previous device caused horrible side effects. On my replacement device, piece of cake. I can swap axis's all day long and hold in position and my screen doesn't go crazy like before.
[Nexus 7 (2013) Q&A] delfin2003:
So are you having issues after the update?
[Nexus 7 (2013) Q&A] :
Replacing it tomorrow guys I will stay there till I get one that's fixed. Hopefully they have plenty
[Nexus 7 (2013) Q&A] Sud0lit3:
Yes the issues (specifically the Vertical Align Craziness) returned immediately after updating. And just like before the issue goes away if the device is plugged in. I did video documentation to make be sure that it's either software or hardware and the result was it was from the update.

BUT my previous device did have issues of its own for ghosting presses but this one does not have this issue. only the vertical problem and only after the update.
[Nexus 7 (2013) Q&A] delfin2003:
What's the device build date? It will say it on the box. Mine is 2013.06
[Nexus 7 (2013) Q&A] Sud0lit3:
Ah good eye! I didn't even catch the date part. Mine is 2013.07
[Nexus 7 (2013) Q&A] delfin2003:

[Nexus 7 (2013) Q&A] Rod3:
Same here, 2013.06
[Nexus 7 (2013) Q&A] delfin2003:
Damn! I was hoping this would only relate to 2013.06, but I guess not. Best Buy demo however did not seem to have this issue and it was running JSS15J build, however I was only able to verify that with maps pinch to zoom as I could not download YAMTT because of 497 error. God damn so many issues! Is this google or is this ASUS? I thinking its ASSUS!!!

what if try to put all 8 fingers on the device screen, does it still work? Four fingers on one side and four on the other

---------- Post added at 05:01 AM ---------- Previous post was at 05:00 AM ----------

I'm still confused whether its a hardware issue or not. I have until 08/15 to return mine...will wait, maybe a patch shows up. Awesome table otherwise
[Nexus 7 (2013) Q&A] Rod3:
8 touches or 10 touches, it still works great. Based on my experiences, it appears to be hardware or at the very least, a bad flash of the update for some folks.

Can you make a video of that if you still have it?
[Nexus 7 (2013) Q&A] Spartanjet:
I bought my 32gb at best buy on 7/26 and it had the jumpy multitouch when on a stand or flat surface. Exchanged it twice while testing them out in the parking lot today they also had the same exact issue. Enough is enough, I got a refund. I mean its not annoying enough that every time I get a new android device a good 25% of my apps don't work, but Ive been through a bunch of Nexus 10's and now Nexus 7's I am thinking I'm pretty much done with Android tablets.
[Nexus 7 (2013) Q&A] wicketr:
I returned mine as well. Best Buy gave me 15 days to try it out, and without multi-touch working or a fix coming my way from Google/ASUS, I had to return it. It just wasn't worth it in the end. With the number of people that seem to be having this issue, I'm going to either wait for them to acknowledge and fix the issue or wait until they come up with a revision#2 that fixes whatever hardware problem there is.

Regardless, there's an issue with these devices that's not getting resolved/acknowledged, so i had to get my money back while i still could.
[Nexus 7 (2013) Q&A] Sud0lit3:
Do you remember if you had the multi touch issue before or after the update?
[Nexus 7 (2013) Q&A] canoo:
This is my second Nexus 7. The first one I automatically updated to JSS15J and touch issues were brutal on it. I returned the first one and bought this current one from a different store. This one I have kept on JWR66N to do some thorough testing. Typing and most multitouch applications are fine. However, as you'll see in the video, it's still not perfect. I'm going to update it to JSS15J soon to see how it works. I will update with another video after I've tested that build out.

http://www.youtube.com/watch?v=UoJjmE9GmOs
[Nexus 7 (2013) Q&A] delfin2003:
I've just looked at your video, i think it's fine if your fingers are THAT close together and it starts to act a bit silly. That's probably because it could no longer distinguish between the charge of each individual finger and starts to get confused whether to read one or two separate inputs. Let us know when you update! I'm watching this thread for your input!
[Nexus 7 (2013) Q&A] canoo:
It doesn't mess up on my Galaxy Nexus when I put my fingers that close together. I haven't got any other android devices to test with.
[Nexus 7 (2013) Q&A] Sud0lit3:
Not always true, It can get very hard for the device to start distinguishing. On my S3 or Nexus 4 it impacted it very minimally (1 zoom in or out) on the maps but its nothing too big to worry about.

What concerns me about the nexus 7 is that especially when you put a case on it your hand wont ground the device (yea turns out if your hand is touching the back of the device the axis crossing goes away) and the crazy spasms come back. after sitting here analysing it for so long it definitely could be an electrical issue.

my question is though why only on the axis, why not just anywhere...
[Nexus 7 (2013) Q&A] canoo:
I stand corrected. I tried again and was able to get the twitches to happen in Google Earth on my Galaxy Nexus while my fingers were really close together. Guess that's just normal behavior.
[Nexus 7 (2013) Q&A] SubMatrix:
It happens with varying degrees of shakiness on my s3. Seems to be related to how slowly I move my fingers together before actually touching (the slower, the more drastic the shaking). I've never noticed it before, I think the previous poster is right that its just a matter of being hard to distinguish between 1 or 2 touches at that distance.
[Nexus 7 (2013) Q&A] delfin2003:

[Nexus 7 (2013) Q&A] trvbone:
So do we have a theory if it's based on build date yet?
[Nexus 7 (2013) Q&A] canoo:
After updating to build JSS15J I have new multitouch issues that weren't present in JWR66N. It behaves just like my previous Nexus 7 which I returned. I'm really torn trying to figure out if this is a hardware or software issue. I plan on returning my current Nexus 7 and waiting to find out if Google eventually fixes things. I'd probably just pick up a 1st gen Nexus 7 or the new Asus MeMo Pad HD but after using the 1920x1200 screen on the Nexus 7 (2013) I don't think I could downgrade to 1280x800...

[Nexus 7 (2013) Q&A] SimFox3:
Same issue as everyone else, though mine is not as pronounced. Version: 32GB. Build date: 2013.07.

I don't have any problems typing, and most of the times I have no issues crossing axis in YAMMT (flat surface, not plugged in)--but there are those times when I have like 2-3 extra pointers on YAMMT and it bugs the crap out of me.

Anyway, the tablet was delivered on Monday (8/15) from Google Play; I will return it in about a week but until then should I unlock bootloader and downgrade? Or do you guys recommend that I return it now?
[Nexus 7 (2013) Q&A] JayBomb999:
For fun, perhaps someone could try to flash the newly posted binary image? Perhaps I'll try after work...

https://developers.google.com/android/nexus/images#razor
[Nexus 7 (2013) Q&A] canoo:
After testing some more, while holding it in my hand instead of laying it on a table, it seems to be much harder to get it to act up. but after awhile I can still get it to start twitching a lot while lining up the axes in YAMTT. It wasn't picking up a 3rd "ghost" touch though like it does when it's laying on my table.

---------- Post added at 08:51 PM ---------- Previous post was at 08:48 PM ----------

WOW! Did Qualcomm finally let Google release the factory image?
[Nexus 7 (2013) Q&A] SimFox3:
I found a consistent way to reproduce the multi-touch jumping problem using YAMTT:

At this point you should experience a brilliant display of fireworks.

Could a few people who don't experience ANY touch-issues please try my procedure. Plug in the charger (USB or wall, doesn't matter) and the problem completely goes away. Looks like a hardware issue to me--any potential software update would simply desensitize the sensitivity and mask the root issue.
[Nexus 7 (2013) Q&A] canoo:
I used Wug's Nexus Root Toolkit to unlock my bootloader. I then installed that image you linked using this method: http://www.androidauthority.com/how...s-4-nexus-7-nexus-10-and-galaxy-nexus-248358/

It installed fine and booted back to the home screen. The multitouch problem, however, still persists in YAMTT. Was worth a shot I guess. If you try it yourself let me know if you have different results. I'm going to go ahead and relock my bootloader now.
[Nexus 7 (2013) Q&A] :
Got a 16gb as opposed to 32(can't see myself using 32gb) when I have a gs4.... different location build date is 6/13 I hope it's fine :( 3rd one now
[Nexus 7 (2013) Q&A] JayBomb999:
Well, it was worth a shot. :)

You mentioned the problem persists in YAMTT. I assume it also manifests in applications? I ask because I saw erratic behavior in YAMTT on the JMR66V build, but the problem never showed itself in apps. Once I "upgraded", the problem, began showing in apps also.
[Nexus 7 (2013) Q&A] phazerorg:
I was already unlocked and flashed the official factory system.img manually and also had no change with the touch problems. At least stuff like this gives us something to do while we wait for something better to come along...
[Nexus 7 (2013) Q&A] Sud0lit3:
problems persist without the update

So I am on my 3rd one now and I haven't updated at all! The problems are still persisting! it is not the software update! I will post a video once I get home. I am keeping this one in case that it is a software issue and that Google does release a fix.
[Nexus 7 (2013) Q&A] :
Got my third... had problems in google maps and multi touch app but all other apps worked fine! I updated and it's still fine I did the browser gaming and photo zooming. I expect it to come back but I see it as a software issue partially... they probably have to change the voltage the screen receives or something... i updated and so far still fine. Having plugged it in At all since I bought it
[Nexus 7 (2013) Q&A] parmend:
I have only seen the problem in yamtt only when not holding the tablet. other than that apps have been working fine .
[Nexus 7 (2013) Q&A] canoo:
I've been using it all evening installing all my apps and logging into all my accounts. It hasn't messed up once while typing. The only apps that really show off that anything is wrong is Google Maps, Google Earth and YAMTT. Even pinch zooming in chrome with my thumb/index finger lined up in the X or Y axis doesn't really cause much grief.

You said yours was only sort of bad but usable in JSS15J then got worse in JWR66N? Mine was perfect in JWR66N and now in JSS15J it's worse but only sort of bad. I keep getting the vibe that this is a hardware issue of varying degrees. Google must have tinkered with the sensitivity between JWR66N and JSS15J.

I should also note that the issue is far worse in YAMTT when its laying on my table. Its very difficult to get it to act up while holding it. I've also had zero ghost taps while typing up this post holding the tablet in my left hand. Tried both swipe and tapping. Typing was the most frustrating thing to do on my previous nexus 7.
[Nexus 7 (2013) Q&A] :
Ok just discovered something, in YAMTT, if I just use the very tip of my fingers to have as litte of it touching the screen I have no issues at all even as close as touching both index. But as soon as I use the plant of my fingers voila fireworks....more testings...anyone care to try and post their results.
[Nexus 7 (2013) Q&A] JayBomb999:
On the non updated JWR66N build, I saw the axis problem in YAMTT. However, in my opinion that build seemed to smooth out and filter the erratic movement. Perhaps that's why app performance seemed so much better. (In one of my previous posts, I attached screen captures that demonstrate touch pointer linearity between builds.)

Ultimately, I think the problem could be a hardware issue with a range of severity. Depending on the build, the software might mitigate the HW defect. If the HW defect is slight, JWR66N might mask it with filtering, better debounce, less sensitivity, etc. If the defect is more severe, the issue manifests regardless of build, as even software witchcraft can't overcome the faulty production.

Of course that's just, like, my opinion man.
[Nexus 7 (2013) Q&A] Sud0lit3:
Here is my follow up video to show that the update had very little to no impact on the touch screen problem. It even existed in the stock one as shown in the video below.

my advice, keep it as long as you can to see if google will release an update or not in hopes to fix this issue.
