All nexus 7 has same software and not all nexus 7 are exhibiting this behavior so obviously it is not software. I can confirm that mine does not have any touch screen issues after doing heavy stuff like gaming etc. Mine has other problem which is a ground issue i.e. if I am not holding my device then it would exhibit multitouch problems but when I hold it in hand or put it on charge or plug a head phone jack which means somehow ground it would fix the problem. The dead spot is definitely hardware problem and check on this forum people are getting replacement for that and getting unit without this problem.
[Nexus 7 General] toastAndJam:
You're right. I called up Google and they said it's a hardware issue. Was really hoping not to join in on the RMA party...
[Nexus 7 General] saadi703:
I know RMA sucks and I myself have not gone the RMA because of other problems I am having but I don't have dead spot problem. This is serious problem and I think this time you should RMA for a better unit. Good luck.

Had my nexus for 3 weeks and really liked it until the touchscreen started playing up last friday. I'd never had any issues with it before that, but once it started playing up it did all the time. Turning the screen off and on fixed the problem temporarily, but after a few minutes it would be back. By saturday night I was fed up with it and so on Sunday morning I took it back to be refunded. Expecting to have to argue the case I was pleasantly surprised to find the shop assistant was a reader of these forums and knew about the problem.

Just trying to decide now if I should order another nexus or hang on for the Galaxy Note 2...
[Nexus 7 General] zephir365:
Have a similar issue with a lot of you here. Watching 720p 10bit mkv for about 5-10 min, and the tablet gets hot, at which point touchscreen does not register my finger properly (very very spotty touch recognition). I'll probably do an exchange today to see if a new one has similar problem.

Fixed my touch screen problems!

I purchased my Nexus 7 from Staples during business trip to San Francisco. My device started having touch screen issues after few hours. Factory reset did fix it and I liked the device a lot so I didn't return it as I thought touch screen issue was just a SW glitch. Issue came back at the airport :(. Unfortunately I didn't have time to return the device at that point. Issue wasn't manifesting itself all the time, but seemed to come up every time I plugged the device in charger. Symptoms were exactly as in this video: http://www.youtube.com/watch?v=uVkvCXDKU2M and the other one in which multitouch is demonstrated. I suspected different applications as a reason to the problem as well as faulty charger. Then I found this thread and became assured that this must be a HW problem.

As I'm living in Finland and don't know when my next business trip to USA will take place I decided to try and fix the problem myself. I took off the back cover and touch screen worked perfectly. Initially I suspected grounding problem but pretty soon came to conclusion that it can not be the case. The problem in my case was the "sponge" pushing (what I assume is) display / touch flex. I have marked that in the attached picture. Even a very light touch to sponge caused touch screen to go crazy. As I don't have the luxury of immediate warranty repair I decided to remove the sponge and my Nexus 7 has been working flawlessly ever since. I can even charge and everything works as expected. When I started charging the device I placed my Nexus 7 on the table. It probably caused slightly increased pressure on back cover and therefore to "sponge". After removing the sponge I can't see any of the touch screen problems I was having. Couldn't be happier as I don't have any of the other problems people have found and device is working as it should, at least for now.

I don't encourage anyone to do what I did, but if you are in the same situation as I was with imported device, you can try to take off back cover and see if the problems are fixed. You should be very careful though not to break the device especially when it's powered on with back cover off. Hope this helps someone.

EDIT: 22.8.2012. Forgot to mention, that turn of WiFi if using device with back cover off. Turning off NFC and GPS won't hurt, although GPS is receiving only. Reason is that antennas are located on back cover.
[Nexus 7 General] devilshunter:
I seem to have narrowed down what causes multitouch issues, at least for my nexus 7. All tests were done on Multitouch Visible Test

1) There were issues when my nexus 7 was in the leather case that I bought very recently. Touch registrations were on and off, and sometimes displaying incorrect points (ie showing 3 dots when i only had 2 fingers on) When i took it out of the case, the problems seem to have went away. Im thinking the magnets in the case may have something to do with it.

2) With tablet out of the case, i laid the device flat on a desk surface. At first, no problems were seen with the test. However, i started applying more pressure to the tablet and the touch registrations started going wack.

3) Tablet is still out of the case, and holding it with hand. No issues at all, regardless of pressure.

I was freaking out today cuz i started seeing touchscreen problems during gaming and during this test. At the end of the day, the solution for me was to take it out of the leather case and hold the tablet in my hand for best results during gaming that requires multitouch. Maybe some of you will have the same luck as me?
[Nexus 7 General] Ozzah:
I spoke to Google today and arranged for a replacement since my touchscreen has this issue fairly often. (Also, my tablet freezes about once a day, so I have to hold the button down to reset it.)

What do I need to do before I send my tablet back to Google? It's rooted with some root software installed like titanium, supersu, adfree, etc.

Should I just make a system image from CWM (to restore onto my replacement tablet), then factory reset and finally "fastboot oem lock"?
[Nexus 7 General] jtc42:
Very interesting, thanks for the insight :) Though this dosmt explain why switching it off and on again fixes it in a second or two :/
[Nexus 7 General] eeansa:
No it doesn't. Unless it's related to "pressure" changes in different parts of plastic. My device wasn't fixed by switching it off and on again though. Symptoms were identical to what has been reported by many other users.

BTW my Nexus 7 is still going strong and it's been under moderate use ever since I got it working properly.
[Nexus 7 General] yukondokne:
i am sending back 2 Nexus today, when the new one comes to replace it, i might try your solution, because i just want a working tablet. i had 2 perfect tablets, no light bleeds, no washed colors, no dead pixels, no screens lifted, but after a few mins of use, either reading or playing agame, the touch would all but stop working on the right side of the tablet.

very sad because i love the hardware and the idea of nexus devices.
[Nexus 7 General] <stu>:
Finally got a new nexus 7 and so far so good. touch seems to be ok on all parts of the screen even with the charger connected. Let's see how it goes...
[Nexus 7 General] JMonkeYJ:
i know some other capacitive touch screen devices (i believe the Dell Streak was one) have had a similar issue and it was caused by static charge buildup on the touchscreen. the static charge buildup causes phantom touches and/or actual touches to be missed because the static charge is misinterpreted as touches. the screen responsiveness would return after turning the screen off, because the screen was grounded while off which got rid of the built-up static charge.

i'm not saying this is the issue with the N7, but the similarities are pretty convincing. it also explains how it can a hardware issue that is fixed by turning the screen off and then on.
[Nexus 7 General] marvvn:
i had this problem consistently for the last two weeks. i noticed it happening with with high intensity gaming. the tablet would heat up and parts of the screen would become unresponsive. the remedy for that worked for me is the screen turn on and off trick. i also had the sound popping issue where the the speaker would make a pop sound and any suddenly no sound would emit from the speakers. the remedy for the sound issue would be to turn on silent mode and turn the sound back on. i was about to RMA when i tried taking it out of my poetic case. that cleared up everything. I have been going strong for almost a week without one single instance of the issues coming up. i now believe the case was causing the problem. it appears to building up a static charge and affecting the sound and also keeping the heat from dissipating normally. I'm curious of this might be the same problem other people are having.
[Nexus 7 General] DrFaulken:
Unfortunately I was having the same problem as you, but my Nexus is not in a case. I am about to RMA this one, which will make it my fourth Nexus 7.
[Nexus 7 General] sagafan:
Same kinda stuff...

Right side of screen (portrait mode) soft reset makes problem go away... ~edit for more detail~ Noticed mostly after long periods of inactivity, and in non-taxing programs i.e. Facebook app.
[Nexus 7 General] redisdead:
Same here. Dead spots when using the tablet after several minutes. It's really a pain. Thinking about claiming a replacement unit if not software related.

Bad screen protector

I was having this same issue, and was ready to RMA it for the problem. However it turned out to be my screen protector was causing the touches not to register. I had a Clarivue screen protector. Once I pulled it off my Nexus has worked perfectly.
[Nexus 7 General] nemrel:
My post & pictures about this issue can be found here (sixth paragraph down):

http://xdaforums.com/showthread.php?p=31176913

The issue was worse when I was using the official rubber case from Google. Since getting a Poetic faux leather case, the problem has not been much of a problem.

Does anyone have one of those anti-static/grounding bands for working inside computers? If you do & also have this touch screen problem, can you try the finger touch thing to recreate this issue? Then let us know if the issue persists. Also does anyone know of a tool or device that can measure the static charge on the surface of a computer/tv/phone/tablet screen?

Here's a picture of what happens when I initiate this problem & run my finger up the right-side. Another point indicator suddenly appears on the left side of the screen.
[Nexus 7 General] Fufu_the_Great:
i have similar issues. mine went from a simple turn screen on/off fix to having to on/off it 2-3 times to fix. and by now my whole screen goes dead not just a few spots.

i rma'd mine and am still waiting to receive the replacement. BUT i dropped it which pushed up the screen maybe a millimeter from the corner. i went to push the screen back down and the sucker cracks on me... smh. you guys think this is something i should fix before returning my device? im afraid to ask google and have them deny my return just for asking.

Nexus 7 touch screen problem

Clutching at straws now for me. I just started experiencing the problem after 4 weeks of use. When I first got the Nexus 7, I would clean the screen every night with windex. Yeah I know the Oleophobic layer and all that that, but I hate fingerprints and oil. I stopped cleaning with the windex about a week ago and started using just a lint free soft cloth and thats when the problem started. Did one clean with the windex and so far for a few hours, no problem. I wonder if the static or moisture of the screen has anything to do with its behavior??

Temporary fix for touch screen problem

Saw this posted in another forum and tried it. Seems to partially solve the problem for me. Disable Currents. I also disabled the Tag NFC app. The touch screen failure seems to have been greatly reduced.

I have the same issue, when N7 heats a little bit the display becomes unresponsive... I even couldn't type on the keyboard, swiping through the menu is also difficult... After restart the problem is gone but just for some minutes and it's back again :( I cant replace it, because it's bought from Canada but I live in Europe... So i dont know what to do... Is there any chance to fix it myself or is hardware issue and nothing cant be done :(
[Nexus 7 General] Djveneko:
Same issue plus one more

Ok so im having that same issue all of you guys are having, N7 has dead spots mine is at random places but mostly in the middle area. The plus one more is that sometimes it would just start touching, typing, even calling by itself like this http://www.youtube.com/watch?v=Fqm773-Wj64 is anyone else having this issue? if there's a thread for the second issue please direct me to it i am going to still google and do some searching but no luck so far.

Temporary Fix of Nexus 7 Touch Screen Issue

Only had my Nexus 7 three days, am currently traveling and I am experiencing the touch screen problem ... I will try this solution ... I believe the back cover is easy to open, so this solution is definitely worth a try.
[Nexus 7 General] eeansa:
Hi ohmi_gaad. The fix is still working. I have no problems at all with touchscreen. Standby current consumption of the device is fairly big though, but most probably it doesn't have anything to do with this.
[Nexus 7 General] chasew83:
+1 same issue here. also noticing it when typing or trying to press some areas, not consistently the same spots
[Nexus 7 General] eeansa:
High standby current consumption seems to be related to either NFC or WiFi. When I disabled both, standby current consumption is much lower. Now I have to find which is the problem.
[Nexus 7 General] jmphillips89:
I contacted Google about this problem. They told me to uninstall the updates to Google Pinyin and disable the app. After 2 days it seems to have fixed the problem for me... Will let you know if it comes back though.
[Nexus 7 General] ohmi_gaad:
Fix touch screen intermittent problem

First let me state, do at your own risk... The problem I had was the touch screen going dead in spots every now and then, with a turn on/off temporary fix.

Solution for me:

I opened the back and gently pressed the ribbons under the sponge into their contacts. I also VERY GENTLY lifted the contacts for the WiFi, GPS and Bluetooth antennas so they would make better contact with the back panel when closed.

The problem has disappeared. I have had the N7 up and running, being used for only 8 hours since with zero issues. My theory is that maybe one of the contacts is not solid enough and is putting noise or static back into the system, causing the touch screen issue..

Will update in a few days..:laugh:

I really don't think it's a software issue I'm almost certain it's a hardware issue. I don't see it all that often anymore but I do see it every once in a while and its definitely prevalent and annoying as hell.

This fix working here too

Both my wife's 8G model and my 16G were experiencing this issue. I performed the fix of removing the small foam sponge and all seems to be good now. My wife and I are thrilled that we won't have to give up our N7s for RMA. Its only been a day so far so I'll update in a week or so if the fix sticks. So far I haven't noticed the increased current draw that eeansa mentioned.
[Nexus 7 General] iamhcg:
Due to I am currently outside of U.S., the only choice I have is send my nexus 7 to local Asus for repairing.

Today the guy in repairing department conducted some tests and saw the unresponsive problem himself. He called me back and decided to replace the whole LCD unit for me (or at least that's what I think he said). So I am going to have my repaired Nexus 7 sent back to me tomorrow.

I'll report in a few days to see if the problem's really gone. If so, I think we have to face the fact that it indeed is a hardware issue.
[Nexus 7 General] eeansa:
Glad to hear it worked for you. As I said earlier, I don't think increased current draw in standby has anything to do with the fix. It's probably been there all along, it just took me a while to notice. It seems to me that in my case disabling NFC hugely lowered the standby current consumption, though it's still fairly high, about 7% decrease in battery charge during 24 hours. Earlier it was way over 15%.
[Nexus 7 General] JaSauders:
Not that I'm trying to justify the issue, but doing a quick sleep/wake up process with the tablet isn't that much of a show stopper to work around it. Since I use smart cases which wake up/sleep the device automatically, I hardly ever see it at all.

My first instinct with this issue is thinking that it could be software based. The whole slide to unlock thing is moreso on the software side of things since the software is what's tracking the touch on the screen. If it senses touch presence prior to waking up, it causes the dead spots to be apparent until it sleeps/wakes up again. I would think if it would be hardware based, it'd be all of the time - not just when it detects touch prior to waking it up.

That said, anything is possible, which is exactly why I wouldn't bet my house on either side. :good::good::good::good::good:
[Nexus 7 General] DrFaulken:
I normally do the turn off and on thing, but that crashes a few games and other apps. Plus I expect a brand new tablet to not have dead spots or require a work around.
[Nexus 7 General] JaSauders:
I would expect the same. I'm simply stating the blunt truth; it's hardly a catastrophic dealbreaker. In my experience, I notice the dead spots right away, long before I'd even have a chance to get knee deep into a game. By that time I would have already slept/woke it up again and have it acting normal by the time I dive into a game.

That said, maybe we'll be surprised and it'll be automagically fixed via software update in the near future? Never know. :good:

I've had a problem where texts sent to me sometimes arrive an hour later. During the times when I'm having this problem anyone who calls me will go straight to voicemail. Outgoing call and texts are not affected. Basically it's as if the phone 'spaces out' from the network on occasion

Other members have reported similar issues.

What is known so far is that: It's not the SIM, it's not a network or provisioning issue.

Is it the phone? Is it the ROM? That remains to be seen.

I've gotten in touch with someone at ATT who is agressively pursuing the issue.

What you can do to help is, if you are having this problem too, please post here. Mention what ROM & kernel you are running, which state you are in and any other relevant details so we can see if it's a widespread problem. It is especially interesting to see if anyone running unrooted stock has it. Otherwise it could be blamed on the user
