[Nexus 7 (2013) Q&A] mcguinness89:
I don't understand why you people think that switching Roms will fix a HARDWARE issue. Return your devices. It is a grounding issue like the 1st generation Nexus 7's. Squeeze the device together (front and back) then try to replicate the problem.. I bet you your touch screen now works! Until the pressure releases and the touch screen malfunctions again (when your hand is not touching the back of the tablet). You're welcome. Thread should now be closed lol.
[Nexus 7 (2013) Q&A] Semantics:
I can't reproduce any problems with the touch screen on the latest version unless I am playing order and chaos and then it gets weird. Everywhere else it seems perfect.
[Nexus 7 (2013) Q&A] Sud0lit3:
it could very well be the case as you mentioned but what will google do with the crap ton of already shipped devices?

[Nexus 7 (2013) Q&A] :
Sorry to say guys but its hardware. Ive had four and it took going to another store in a different state to get a good batch. No problems at all. Works in multi touch app and all. Even works when laying on the table. Huge sigh of relieve I started with the 32 GB but got a 16. I figured the 16gb had a bigger batch since it was the cheaper version. Though I'd like more space I'd never turn this in for one that could very well have problems ! Its also on the newest update I figured I'd go ahead and install it to confirm whether its hardware or not. I'm thinking its both. All devices do not use the same exact screen I'm sure. So maybe some are okay and the others are overvolted and it gets worse with newest update
[Nexus 7 (2013) Q&A] Sud0lit3:
this is how i definitely feel about this. its most likely a problem of both software and hardware. considering how many tablets are distributed with the touch issue i wonder how asus/google will deal with this problem...
[Nexus 7 (2013) Q&A] jjjsong:
I have the same multi touch issue. However it seems to go away if the tablet is charging.

I may just keep it and hope there will be a miracle software update fix lol
[Nexus 7 (2013) Q&A] :
I have the same problem. There are a few things I've noticed.

1. If I take the microusb plug and touch the metal on the USB housing on the device, the problem goes always/extremely lessens. this leads me to belive this a grounding issue. I know this has been mentioned before.

2. The erratic behavor happens almost always when you cross the axis on the X plane if you are holding it one handed.

3. Certain areas of the device is affected more than others.

I BELIVE THIS CAN BE DIRTY PATCHED in a software update or kernal mod. If anyone of you have a Galaxy S2 i9100, you should know about the Dorimanx Kernel. You can modify touch sensitivity and behavior on a kernel level. I get a erratic touch screen while charging on the i9100 and the problem is fixed by messing with the touch filter.

This is what the N7 needs; a kernel that allows you to mod touch filter and sensitivity. The GS4 can increase screen sensitivity on demand if you are using gloves. It does that on the kernel level I believe.
[Nexus 7 (2013) Q&A] trvbone:
What is the build date on the newest one you have?

So if I have no problems right now.... Should I do the update?
[Nexus 7 (2013) Q&A] aimfire72:
I first got a 16gb, no problems with the screen at all. Then I stupidly exchanged for a 32gb and noticed the touch problems immediately. Lots of "bad spots" where taps won't register on the first try, mostly on the top half of the screen. Sometimes I need to hit the home button 2-3 times to get it to respond. So I'm wondering if maybe the 32gb versions are affected more by this? I know another guy who just got a 16 and he has no issues.

Sent from my Nexus 4
[Nexus 7 (2013) Q&A] delfin2003:
For all of you who DON'T KNOW THIS: You can go to settings and keep tapping build number until it shows "You are a developer". Once you are a developer you will be able to see developer options in settings. From there, you can tap "Show Touches" and you can see it acting up even on the home screen.

It seems like Google is aware of the GPS issues but still no word on touchscreen issues . I hope its software fixable
[Nexus 7 (2013) Q&A] trvbone:
I'm on my 2nd 32gb I only have the grounding issues when using one finger on table but once I rest my other finger along the edge then it responds. Kinda annoying. I'm not sure if this was an issue before update can anyone confirm?
[Nexus 7 (2013) Q&A] :
Still no problems. Even with it in a case... 16gb seems bought more so more batches might wanna try that if you can live with 16gb like I can.
[Nexus 7 (2013) Q&A] Oxybenzone:
My first one, 16GB 2013.07 updated, had this issue pretty consistently. I made an exchange and stuck with JWR66N on it. So far I haven't been able to reproduce the erratic touch issue. Tested flat, plugged in, and held. It seems to be a hit or miss hardware issue.

Edit: The replacement has the same 2013.07 build date

[Nexus 7 (2013) Q&A] whoamanwtf:
The new Elemental Kernel fixed the jumpy multitouch on my device, when I disabled the magnets... freaking magnets man
[Nexus 7 (2013) Q&A] canoo:
Mine worked perfect in JWR66N. Have some multitouch issues in JSS15J now. It pretty much vanishes when I hold it in my hand though. Try updating.
[Nexus 7 (2013) Q&A] JayBomb999:
Magnets? How do they work??

Seriously, that is very interesting. I am going to try this.
[Nexus 7 (2013) Q&A] NH2G:
I cannot confirm. I installed the ElementalX 0.8 kernel, and disabled the magnetic on/off switch and there has been no improvement. I am on stock 4.3.
[Nexus 7 (2013) Q&A] whoamanwtf:
Hmm, well I know before I couldn't use swype and now I have no issues swiping everything out on the first try.
[Nexus 7 (2013) Q&A] JayBomb999:
Now that I think about it, you're likely not disabling the magnet itself. Rather, you're just disabling the OS's response to it.

There's no "off switch" for for a magnet unless it's electromagnetic, which I doubt.
[Nexus 7 (2013) Q&A] whoamanwtf:
Well yeah, but the response could cause some weird interference, it is made to react to a magnet being applied to it in the form of a smart cover. So with it always looking for that connection maybe it helps getting rid of it... all I know is my swype works now.
[Nexus 7 (2013) Q&A] JayBomb999:
What about multitouch? Do you see issues in apps or YAMTT when the axes cross?
[Nexus 7 (2013) Q&A] trvbone:
OK guys I just did an experiment.... Screen protector on: When I have the tablet laying on my bed or a towel and I try to do the one finger method no response. Screen protector off: same test one finger works. Apparently the screen protector is blocking my finger from grounding when touching the screen with one finger.
[Nexus 7 (2013) Q&A] NH2G:
I re-installed the kernel with only the disabled magnetic on/off mod checked and multi-touch is working just as well as its predecessor.
[Nexus 7 (2013) Q&A] whoamanwtf:
I do not, I just downloaded and tried it. I can put my hand down with 5 points active and spin so they all cross paths multiple times and I get no flicker or swapping like I did before.

You may have just saved me from attempting to get a refund.
[Nexus 7 (2013) Q&A] Lexord:
So, that worked for you? Interesting :thumbup:
[Nexus 7 (2013) Q&A] NH2G:
So far, so good.
[Nexus 7 (2013) Q&A] JayBomb999:
Just so I understand, you originally did not have success, then you tried something different and now it works?

Would you mind detailing your process? I'd like to try myself...
[Nexus 7 (2013) Q&A] whoamanwtf:
I did what he said in his last post before, unchecked everything except the magnet box in the kernel installer.
[Nexus 7 (2013) Q&A] NH2G:
Just a heads up to all, there is still a small bit of unusual touch behavior, but it appears to be related to sensitivity. The problem may not be completely resolved, but it seems more likely that this is a software problem. Perhaps the software sensitivity is set too low and/or something is causing interference. Hopefully in a few weeks, all of this will be forgotten.

[Nexus 7 (2013) Q&A] parmend:
I feel it could be software . I just got a new one from office depot and tested on j66 build with yamtt and no issues with touch screen . tested without holding it and it worked perfect . ran yamtt several times. Installed the update and started seeing ghost touches . I really believe it can be patched with software update but getting Google/Asus attention on this issue might be the problem
[Nexus 7 (2013) Q&A] sonnydroid:
So I took the plunge. Unlocked bootloader + rooted and now on the JSS15J firmware (07/2013 build date) and I have NO multi-touch issues on yamtt. Happy camper here :D
[Nexus 7 (2013) Q&A] Sud0lit3:
Few things to make sure when you're testing.

1) your not plugged in

2) your not touching the back of the device

3) the device is laying flat on a non conductive surface (to pretend you put your device in a case)

4) do 3 test:

a) match 2 touches on vertical axis

b) match 2 touches on horizontal axis

c) 5 finger touch using one hand and make sure your fingers all criss cross each others axis

if you do not have any symptoms at this point I must say you are part of the lucky few! :)
[Nexus 7 (2013) Q&A] sonnydroid:

I just downloaded the YAMTT app and tested it on my 7(2013) 32 GB, totally stock, and it doesn't have any issues with inputs from 1 through 10. Ran out of fingers, suppose I could get a grandchild or two to assist me but thought 10 would be sufficient. I've got all my applications installed and have only had a few issues with some that don't appear to have been updated to support the new 4.3.3 environment.

I feel bad for everyone with this stupid problem. Google better fix soon
[Nexus 7 (2013) Q&A] :
Anyone think we can pull the kernel off the old build and make it work with the new build?

There is a backup of an old build on page 13.

I'm thinking something in the old kernel covered the problem up..
[Nexus 7 (2013) Q&A] Sud0lit3:
Not exactly cover it up but it wasn't as erratic and annoying. non the less tho it did seem to act much better for most devices.

Edit: Im keeping this tablet for 10 days to get feel for it and see if I truly need it then probably return it and get one from a batch made around September. I think waiting out is the best solution at this moment. It's a definite hardware AND software issue.
[Nexus 7 (2013) Q&A] :
Agreed. Its both a hardware and software issue. There is a physical fault from the way this was made because of the grounding issues. The kernel on the new build isn't calibrated as good as the old one. I think if the has a higher move filter, it will be less erratic (cover up the real problem which is the grounding issue) but thata good enough for me......

so i guess others who are saying they dont have the issue were doing it wrong like me...i never had it set down on a flat surface and i was usually holding it in my hand
[Nexus 7 (2013) Q&A] delfin2003:
So I exchanged mine today and JWR66N did not have any issues whether plugged in or not. Updated to JSS15J and BAM, issues are back! Sounds like a software glitch to me!
[Nexus 7 (2013) Q&A] Sud0lit3:
Which is why I made those steps so people can take their time and follow it easily. The reason why it wont work while you're holding the device is because your hand is grounding it therefore getting rid of the issue.

The worry comes in when people get smart cases or all sorts of other things where they won't really be grounding the device always.

It's essentially a electrical hardware issue. The kernel can assist in hiding softening the problem but not always fully resolve it. but a good 90% which should make the device fairly usable.

non the less I paid good money for the device so I'm willing to wait it out until school time and pick one up then.

---------- Post added at 07:44 PM ---------- Previous post was at 07:42 PM ----------

the problem is more well hidden previously but with the update it made it much more visible. the problem however has always existed on the device because in reality is hardware problem.

EDIT: If it makes you feel any better I downgraded mine to the old firmware and the erractic crazy touch are there. My record for it going crazy without me actually touching it is 23 seconds. I was trying to take my phone out and record the fireworks for google but failed :P

[Nexus 7 (2013) Q&A] Sud0lit3:
It is a hardware problem along with software issues. It's a grounding issue. just like the original Nexus 7. Other devices have suffered from this and best Google can do is release a generic Kernel that can soften/hide the issue.

---------- Post added at 09:56 PM ---------- Previous post was at 09:54 PM ----------

zip the folder and host it. as for personal info there are software to remove it (Wugs toolkit I believe) but you have to make the backup using that software to begin with and at one point it will ask you what kind of backup you want.
[Nexus 7 (2013) Q&A] stimr2:
I read on the google support forum that a screen protector could cause a grounding issue. Well, I took off my iLLumiShield screen protector and it helped. Now I can put my Nexus 7 on a ungrounded surface and the multi touch actually responds.

I guess won't be using the iLLumiShield screen protector. I wonder if a different brand would make a difference. Guess I'll just buy the Spigen or Seidio and test it out.
[Nexus 7 (2013) Q&A] :
Sorry guys :\ I've used my tablet while standing on wood , rug, plugged in , not plugged in, in my case , not in my case , holding it, laying on the table. It's been 2 days and not one issue... i use this thing a lot also... the only thing is that the screen is sensitive but I have no problems at all doing anything and the pinch to zoom works fine in all apps and I type perfectly fine
[Nexus 7 (2013) Q&A] stimr2:
With the screen protector it would work fine on my wood desk. But once I put it on the bed or tablet stand the problem would show up again. The tablet stand I use is a plastic with rubber feet. If I touch the tablet stand the multi touch works fine.
[Nexus 7 (2013) Q&A] :
So I can make happen if I really really try in the browser but it only does it a tiny bit... like I said the screen is extremely sensitive and they need to do something about that... sometimes I'm like pinch zooming and it moves before I think lol

Also yamtt when I use two fingers and put them on the same axis they move around a little (the blue and red circles) and as you guys know it's only on the same axis... but doesn't show itself when playing games or anything ... the software clearly needs updating cause the screen is strange. There's no way it's just hardware... only when on the same axis? That wouldn't make any sense. If it was the screen it would have problems always

Bottom line is I still have the issue... It only applies if I hold my thumbs together in one spot on the same axis not when I'm pinching to zoom or gaming... Nonetheless its still there. I don't even know what to do at this point ?! Its my fourth one... Can we almost guarantee that a fix will come or should I give up and return it

[Nexus 7 (2013) Q&A] Sud0lit3:
My best recommendation (basically what im going to do) is wait a few days until your near the last day of the return (so like 13/15 days) if google smartens up and somehow actually fixes this then we're are saved from this multi touch curse. Otherwise return it and wait it out until asus puts their act together and a quality device for once without having major flaws... Essentially what im saying is wait until september, the device will go fully mainstream hell im sure there will be back to school discounts on it even and around that time might be a good time to pick one up. That's what my plan is.

[Nexus 7 (2013) Q&A] cdmoore74:
The first unit I got was perfect. No issues at all. But when officemax had their 20% off coupon I could not resist getting a 32gig for $215. Got that sucker home and major backlight bleed and intermittent double taps while typing. The multi touch app confirmed my issues. With 2 fingers held down it would sometimes register 3 fingers while intersecting the x and y axis or it would not hold my finger tracking causing the app to think I had let go. My Nexus 7 2012 and Note 2 does not do this so I now there's something wrong. I could have lived with the backlight bleed but the double taps on the keyboard is driving me insane and I don't know if it's software or hardware. I tried different roms and kernals, plugged in and unpluged and it still happens.

This is what happens when you get greedy! The other issue was GPS not working but that's another thread. Returning it and getting a refurb Note 10.1 for $249 at walmart. Resolution sucks but I love that S-pen on my Note 2.

[Nexus 7 (2013) Q&A] ascar1s:
"Fissure" in middle of touchscreen

Since the very beginning, I had trouble moving icons around the home screen. Then, after getting things set there, I thought things were sort of, kind of, OK. Then I tried using swipe-style typing. I realized that any swipe that involved crossing the "prime meridian", so to speak, of my screen would fail: the screen would detect that I had lifted off the screen at that point and then set my finger back down on the other side of the "meridian". Needless to say, this produced gobbledygook. I replicated this a number of times (what I didn't do, and will try shortly, is see whether the meridian flipped when I rotated the screen) and then removed the Skinomi screen protector. No change; no improvement—which didn't surprise me because I had the home screen icon issues before attaching the screen protector.

I will post pictures asap of the screen test which shows this effective "fissure" along the middle of the screen. Hardware or software, this makes the tablet fairly useless. Going to take back to Best Buy on M or T. Just not sure whether to exchange or replace.

I'll swap over to the tablet and post the screen grab of the screen test showing the effective fissure, for lack of a better term.
