Update: Star this Android issue if affected: http://code.google.com/p/android/issues/detail?id=58401
I'm noticing intermittent bouts of erratic multi-touch on the Nexus 7 (2013) 16GB. I exchanged one device already hoping that it was a HW defect, but my second device behaves in exactly the same way.
Chrome, Dolphin, web-view, maps (especially maps) will often jump all over the place during pinch-to-zoom. Sometimes it works fine, but too often, it jumps zoom levels erratically. Edit: This also manifests as double taps and/or "ghost taps" when using the keyboard.
I've installed YAMTT (Yet Another Multitouch test) and I've observed the touch points disappear, change direction and even suddenly register a 3rd touch. None of my other devices do this.
I'm reluctant to exchange the device yet again, but I haven't read about anyone else who's witnessed this. Am I alone in observing this behaviour?
Edit: Here is a terrible video attempting to highlight what I'm seeing in YAMTT: http://www.youtube.com/watch?v=_ZRiMiNzs0U
And another video in Google Earth (fixed): http://www.youtube.com/watch?v=14cPiiM3Pwg
Someone else experiencing the issue: http://www.youtube.com/watch?v=Xpl26UgcuSs
FINAL UPDATE: I exchanged the device again and the issue is gone (so far). My advice: if you're experiencing this issue, return it. If it continues to happen, return it again until it works.
As a side note, for those experiencing the mushy/hard to press power button, that issue was fixed for me as well.
Final Update Part 2: I am sad to say the issue is still present after all. I'll admit that it is less prevalent than with my first two N7s and the "jumps" are less severe. However, it's still there and I'm not prepared to live with it. Therefore, I am returning the device to get my money back. I'll keep up to date with this issue, and I'll likely buy it down the road when a clear resolution presents itself. I know it would be a great tablet without this problem.
To recap my experience:
First N7 had erratic multi-touch, stiff power button, keyboard and other touch screen issues. Exchanged.
Second N7 had a good power button, but the erratic multi-touch and keyboard issues were still present. Exchanged.
Third N7 had a perfect power button and no keyboard issues, but the erratic pinch to zoom was still present (though less severe). Returned.

You're probably right. I was just concerned that no one else had mentioned it. I find this behaviour quite annoying.
Does the issue go away if you actually held it with the other hand (going by video)? Sounds like the behavior of the 1st gen N7.

I'll try that, thanks. I have the original Nexus 7 as well and never noticed this issue. Could you elaborate a little? Was the issue eventually resolved?

It's designed to be used on a grounded surface either held in hand or on a grounded surface. It's an electrical behavior so I doubt software would change that. Please try held in hand and report back.

I've got this a little bit, glad I'm not the only one with the problem, mine only does it when I hold it above me and use it lol. Everything else is fine with mine so I'm keeping it.
Are you sure this is a software issue?
I remember back when I had an HTC Desire, it had multitouch issues but the fault lay with the digitizer and no update could fix it.

I've tried gripping in both hands, from the bottom bezel, on the table and on the couch. Still, I see this behavior. It's not constant, but it's prevalent enough that I don't know if I'm going to keep it.
It sucks because otherwise I really love it.
I dunno. I'm seeing weird anomalies with mine. Moving 2 fingers around, a random 3rd pops up.
Hopefully just software woes. The Galaxy Nexus did this, N7 did this, and now the new N7. Its rare. Haven't had a problem.

I just ran the same tests you did using YAMTT and did not have any of the same problems. I haven't noticed any mutlitouch issues either.

I found this thread looking for someone else who was having the problem I was - my device was doing exactly the same thing in Google Earth. Thanks for posting it!
Oddly enough now that I've found this thread, the device isn't doing that anymore. It's tracking perfectly in Earth and also in YAMTT.
It tracks fine when being held in one hand, on a grounded or not surface, when touched with one hand or two.
Very odd.
I had this issue with my 1st n7 2nd gen (which i bought yesterday). I returned it to bestbuy and got a new one which seems to be fine.

I've already exchanged it once and each had this issue. I think I'm going to try again tomorrow. I'll report back.
I had a similar issue with google earth on my 1st gen N7. I can't test it anymore, tho, because its sitting at the bottom of a lake. But it would randomly zoom out or in like crazy or jump halfway across the world.
I have this issue extremely annoying. My keyboard double presses letters at times, zooming I have ttrthe problem, trying to long press a link I also get it unregistering touch
I hope this. Is. Software I don't waqmt to return this. Otherwise perfect device. You can see it happoening as I try to type
This actually happened to me for the first time about an hour ago. As said before, I hope this is a simple software bug, and not some serious hardware issue. Quite frankly, I have a feeling that going through a return is going to be messy, as I've bought mine from my local Gamestop.

I know it's only one person, but this leads me to believe it might be a hardware/quality issue. I have exchanged mine once for this issue already (Best Buy) and it was extremely easy. I am going to exchange one more time and will report back my findings.

I didn't mention the keyboard issue. I too am seeing ghost taps when typing.
Hmmm. No ghost taps here. I've been on xda a lot since I got this.
Not good though. Could just be a bad batch. Seems like the dead spots would be caused by a hardware issue... Bad connections or something.

I got my nexus 7 today, but around 30% brightness the screen will start to flicker like a candle and it's pretty unbearable. I was wondering if this was a softwarw problem that could be fixed or whether I should just exchange it for another one.

Same problem if the environment light is not stable, the light sensor is so sensitive that will make the problem happen. The Nexus 7 1st has this problem too. The AUSU' offical explanation said that the problem is normal situation. Unbelievable!!!
hmm.. I dont see to have this issue? Are you able to provide steps to replicate it?

No I'm not, it happened today while I was visiting a friend. I just dropped my brightness down to about 30% and this horrible flickering just started, I got home today and I can't seem to replicate the problem.
Taking it back on Saturday anyways because I was watching a movie and oh god, I got some BAD light bleed.

I haven't seen a lot of this reported at all really. Before you return, if you could, take a short video of the issue happening. I'd be curious to see what it looks like. It does sound like a bad panel, though; so definitely let us know how the new one works out.
I just got my nexus today and have experienced this flicker issue within 10 minutes of use , I'm happy to say I immediately came to my trusty xda app for answers and as usual found one !! Seeing that I'm not the only one having this issue I'm thinking its a hardware problem.

I read about this here or some place else and if I remember they said not to lower brightness below 40 for those with the issue.

My actual camera has been lost for like uh, 4 months lol.

This is exactly what happened to me, also I can reproduce it while having my brightness in the 20-50% range while having a subpar wifi signal.
My G4 has just started showing screen burn in, mostly the notification bar. It appears faintly red, and according to the burnt-in time, it was less than 20 minutes ago. I have been using it alot since 3 days ago, and have left the screen static for far longer than this without problems. Does anybody have any suggestions?
Update: things seem to "burn in" after just a few minutes of being on-screen. Only solid white images and text do this, and they leave behind a red shadow on lighter grey or blue colors
update 2: "burn-in repair" apps definitely work, but my status icons burn in again, in the same way, within 5 minutes. I'm honestly crushed, as I loved this phone. It seems I'll have to return it..
Could there be a fix, guys? I'd hate to have to return it
Try this. Use phone for 30+min. Plug charger when phone is on. Turn off phone and wait blue battery sign. Look at top side screen. There you will see al signs. This is my post with same problem: http://forum.xda-developers.com/showthread.php?t=3289496

That's my exact problem. Guess I'll return it and get a different phone altogether. The g4 is a complete bust, it seems. Some have a loose motherboard, some overheat, some have green blobs on the camera, some of their cameras stop working altogether, glitchy lcd's, dead pixel clusters.... Geeeeez

What? I've not heard of most of the issues you described....
I've noticed a small amount of image retention (not burn in... LCD's dont burn in!) when booting into TWRP, but when actually using a ROM there's no issues.
I have no idea what you're talking about with loose motherboards or overheating... I've seen a couple of reports of a green blob on the camera, glitchy LCD's was a single batch of Verizon/Sprint models, and I don't know what you mean by dead pixel clusters.
Sounds like you're looking for reasons to dislike the phone...!

No, I love the phone, believe you me. The motherboard thing has several threads here, and the other issues are mostly isolated, but also mostly carrier specific. You have to dig a little to find them. It's just coming down to risk. I want as little risk for as much return as possible, so for me, all those reported problems (even though they are few and far between) are just as important and search-worthy as things like chipset, ui lag, camera tech, screen size, etc are to other people.
The lg g4, on paper, was perfect in every way, and so I assumed the return on the investment was going to be far greater than any risk. Now that something happened though, I just can't get over it.
It's an electronic device. Logically speaking there will be some with issues. You can't avoid that.
Reading forums isn't a good way to find out about the reliability of a device. People are more inclined to post problems and negativity on review sites and forums. There are far many more G4's out in the wild with no problems whatsoever than ones out there with issues that you describe. Hint: If you have to hunt around to find mention of a problem, it's probably not very widespread...
Chill out!

You're absolutely right man. I went into a cell phone store today, and of all the ones out, the g4 is still the best, the sexiest, and has the most features I like. It also feels SO GOOD in hand. I don't think I'll be able to go with a different phone now....hahaha
I do just need to chill.
Hey there,
I have some issues with the MTCB. Someone had these before?
First problem which is already quite annoying is that pictures are kind of burned in and still show shadows on the other screen
Second problem which is even more bad is that the display flickers. This is more or less obvious in different scenes.
When looking closely it seems like there is a grid (coming and going in the same frequence like the music is playing?). The attached video shows it.
Especially with white background the flickering gets very bad.
Don't know if this could be related to the Malaysk Firmware I use. Or is is it a hardware issue?
Also contacted the support. Let's see what they say...

This is commom in these units.
It's worst when it's hot.
I kinda fixed mine opening it and adjusting some kind of screw near the screen. You turn it and screen gets darker, you need to find a point between too dark and flickering. But when I park my car at the sun, and it gets hot inside, screen get bright again, so flickering and persistent images.
And here is a video about it.

It's commom. That's why Joying even put a video online to show how to fix it.
I believe that when they produce the unit, it's now well tuned up, or it's cold in the factory and they don't realize, so when someone who lives in a hot weather area install it, the problem appears.
It's a bad hardware design, they use analog potentiometer, they should use some digital and automatic one to regulate screen frequency.

Well, Like I said, I ve not heard much about it in the 3 years I ve been following the threads on here, but I do remember Joyous having problems with their screens and 5.1.1 - they couldnt get 5.1.1 to work on their 4.4.4 RK3188 units unless the screen was changed !! Sounds like its more a problem with Joyous units.
I agree there's not many complaints about this problem here, that's why I believe that may be some "quality check" sloppiness. It's very simple to solve anyway.
But all units seems to use analog potentiometer, so, bad design. There's nothing to do with Joying only and the fact they changed screen to update to 5.1.1.
And most users in this forum don't live in hot weather areas. In my case, Brazil, is hot must time of the year, above 34 C degrees (93 F), in the shade.

I looked at the map and St. Helena is a little to the south, a direct flight seems a better option.
But feel welcome if you want to come to Brazil someday.
It's a bit messy but it's a good country. I'm not going to take you to meet any favela, by the way. Don't know why tourists are so eager to go in one, it's very dangerous, and I don't think they represent Brazil that much, so many different beatiful places to go.

Hey there, thanks but the video is not working.
I did not open the unit yet to check if the screw will improve. But I will test soon when I find some time.
By the way it's around 0°C here. So not very warm
Attached is another video. The flickering of the right white picture is actually visible. It's not a flickering of the camera.

Just open the unit and fix it, very easy.
Took some time until I tried the fix. But the screw fixed it.
Carjoy recommended a power filter, but since the screw fixed it i prefer this...
The screen is now slightly darker. But I like the crisp image and better saturation of the colors (and of course no flicker).
Thanks!

Obviously that isn't normal, but I don't think it is a widespread issue. Did rebooting fix the problem? If not, perhaps one of the temperature sensors is reading incorrectly (ie has failed or is faulty). If it persists, I would contact Google support and see what they say.
