They say Google is aware of this issue and is looking into it...I bet it's just a software update...I trust Google more than Samsung or HTC...

Crap, using the same app as you I also found my device has this touch problem. Only noticed when using two hands together near the edges, otherwise everything is fine. I also think its more software related than the hardware, since the touch works fine with one hand. Not much an bother unless unless app that require multitouchs with both hands. Hope an patch fix for it soon.

Edit updates: hmm it seem the problem disappear after I finish typing this post??? Randomly triggered?
Seem to happen when you have two fingers on the same line it start to jump a bit.

Is there an app you can use to test the touch on the tablet?

Rule9 told me this app called " Yet Another MultiTouch Test" this is one one showing my device problem. There is one under developer option and I used another app before and both turned out fine. So not sure if that app is the problem causing this, you can try and post your result.

I've read that only the tablets with the JSS15J build number have the problem. I'm sure nexus will solve the problem soon, doing an OTA update. If you return to exchange, see if the store will allow you to open it to check the build number. Good luck on that. I'm just sitting tight. They know of the problem and maybe do a massive exchange if nothing else?? Do you think so?

That's suggested but not confirmed yet. There's two possibilities being looked at over at XDA right now. Those who've been suggesting it's the JSS15J build update could mean it's a software issue. However the greater number of reports have dealt with how the problem arises if the tablet is not plugged in and on an ungrounded surface (tabletop) in which case we're looking at a grounding issue which means a hardware defect in the affected units. But we're not sure either way yet. Just to dispel any notion that all these people are simply mistaken that the testing app is actually faulty, I've tried this on two different touch test apps and both have recognized a problem.

I just got home with my new unit, I'm going to set it up and update to JSS15J and install nothing except the touch test app. If this unit is also defective, then I'll probably be looking at the iPad Mini 2 coming October. At least that way I'll be able to just waltz into the Apple store and get an immediate replacement for the entire year warranty instead of dealing with mailing in RMA hassles. Anyway, I'll report back here after setup.

Update. New tablet is registering even worse than the one I returned. It's even crashing the app this time. The last unit kept jittering at 2 touches and showing a 3rd ghost touch when the touches are aligned vertically. This unit climbs all the way up to 5-6 ghost touches and then the app shuts down.
The issue as others have described, occurs when the tablet is placed on a tabletop unplugged. If you're holding it in your hand, OR have it plugged in and on a table, it's fine. That's some kind of grounding problem.
I have 14 more days now for this to be resolved, or I'll be toting the 2013 Mini around come Oct. Sorry Asus, but this is twice now, I don't give 3 strikes.

I couldn't resist. I went for a 3rd, this time at Staples rather than BB, trying for a different batch. I'm 99.9% sure this can be fixed with an OTA update now. I decided this time around to install YAMTT before the 2nd build update and lo and behold no issues. Installed the JSS15J build and yep you guessed it: issues. The upside to this is that for some weird reason, this time the erratic 2-touch is really really faint. In all honesty I don't think I would ever have detected it if I wasn't reading tech news to find out about it. The second purchase was the worst, this one is the faintest, (some might even call it an acceptable quirk of touch screen devices if it had never become a public issue) and the first unit was somewhere in the middle. If nothing else happens, I might even hang onto this one, 2-touch issue and all because the level of it is so faint I doubt it will impact my use and the tablet overall smokes everything else out right now. I didn't want to be forced to switch to Apple if it could be avoided, although I am still annoyed that I had to exchange 3x to get a good unit.

I guess you're like me with an device with little multi touch problem (can type perfectly), and I assumed it to be software issue (android 4.3 OS) and from reading what you wrote that seem to be the case. So, if its more software related we can keep the faulty device and hope there can be an patch fix address the issue right?

That really depends on you. This 3rd one is so faint I wouldn't have noticed it if there hadn't been articles and threads popping up about it. My first two were more severe. I might keep this one. My nexus 4 for example has the much less known about issue of slight attenuation but it only occasionally is noticed deep inside heavy and thick concrete buildings so I accepted it.

I'm not going to place full trust in them fixing this so I have to decide if it's bothersome enough to care in case they don't. But I do believe it's fixable after my latest findings

JSS15J is not a physical unit batch number, it's the build number for android 4.3 r2.1 (for reference, it's the 5th android 4.3 update). this would indicate a software issue. mine reads JSS15J and I've had no multi touch issues with it at all, so it seems there needs to be something third party or some kind of combination of settings causing this issue to crop up.

It won't be 3rd party, tons of us have been testing after fresh installs, no 3rd party apps. Between this, the GPS issues, and the random reboots all I know is I'm damn glad I didn't get the 32GB model. Frankly I don't trust this enough now to spend more than the bare minimum on it. It's got enough goodies to justify being a $250 tablet, but no more than that.

IMO the best way to dispel that notion is to not use any 3rd-party testing app at all.

Simply go to developer options and turn on "show touches" and "pointer location"

Then go to Google Maps and cross the lines on your two fingers.

If the unit has multi-touch issues, Google Maps will start rotating, zooming, and warping you all over the world.

You can perform this on any stock ROM w/o need for wifi connection to download another test app, and everything is stock from google. The show touches and pointer location isn't even an app, it is part of the OS, so it is highly unlikely to be causing the issue. It is just displaying what the OS sees.

If people then say it is a Google Maps issue, you can just go on the home area and cross your lines. If you have bad multi-touch issues, you'll see ghost taps away from where your fingers are.

People have also been showing the problem that way as well.

When I did it this way my tablet is fine though (developer option & google maps).
