I remember reading a few days back about people having issues with screen tearing. My screen will display a symptom where it has a jagged line shoot across the center area of the screen real fast and then go away. I was wondering if anyone found a solution to that?

No progress has been made, yet. Some think it will be fixed in a software update. When I notified Google support of the issue, they thought it was a hardware problem, but if several people have the issue, maybe it's software.
I'm hoping it is fixed in a software update. That is literally the only issue I have with the tablet.

Yeah I hope so too, but I already have a replacement on the way. I have some other issues with mine though that I felt warranted getting a replacement.
Does the tearing happen to you all the time or just in certain apps? It only happens on mine when I'm playing music. It will show up for a split second as a quick horizontal line then disappear. The line appears in different areas of the screen each time. I notice it the most when it happens in Chrome, but I've seen it on the homescreen and in other apps as well.
Mine happens frequently throughout the ui. Xda app, chrome, everywhere really. If it is a software issue though there really is no point in exchanging. It seems to happen more frequently in an app with a light background.

I have this problem as well.. I only notice it in tapatalk though.. I'm not sure If its because I use tapatalk all the time or what..

Mine happens in chrome pretty regularly as well. Could it be something with the video drivers for this thing?

So apparently it was a bad kernel that I was using that caused the problems. Flashed a completely stock build and the problems are gone. To the people that chimed in and said they had the issue, are you on a stock ROM or did you change that and the kernel?

I've noticed this, but it's only happened twice (so far), Once was whilst using chrome, the other time just sat on the homescreen. I'm currently using stock.
(Not too worried, just as long as it's not a line of pixels about to give up the ghost as some other people have had).

Happens to me on stock rom. My N7 is not rooted or unlocked.
Pretty sure this only happens when you force GPU acceleration. I had the same issue, turned it off, and never saw it again.
Of course I love GPU acceleration too much to leave it off, but a jagged line every once in a while is not a deal-breaker for me.

Glad it worked for you, but I don't have that option on nor any other's enabled in the development menu. Regardless, the issue persists.
Is there anyone else having this issue?
I received a replacement today, but I couldn't escape defects on that on that one either. I'm trying to figure out if I should hang in there for a fix on the screen tearing/horizontal line issue, or if I should just send both back and call it a day.

I just found this thread. I have the same issue. I'm on stock kernel, unlocked/rooted, and stock rom. I don't have GPU acceleration forced.
Any further ideas? Could be a driver issue.

People here think the screen flickering issue could be resolved in software, but I'm not sure about the issue we are having.
I might go through the unlocking process just to see if the horizontal line stuff happens on other roms/kernels.
I really hope it can be addressed in a software update. I just struck out on my 3rd nexus. All of them have screen defects. All have had other issues like creaking and slight screen lift, but those are a lot less of a problem to me. The original one is ok except for the horizontal line issue. My two replacements each have dead pixels and dust in central areas of the screen.
This is ending up to be a very tiring and disappointing pursuit.
If it's a software problem it's likely to be in the tegra3 proprietary driver blobs. If this is indeed the case, changing rom and/or kernel will make little difference (because they share the same blobs).
It might be possible to work around the issue outside of the blobs but its likely only nvidia can fix the root cause.

Hopefully someone at Google watches some of these threads. I have 2 nexus 7s with this issue. Thanks for trying to save me the time of trying a different ROM/kernel, but I might still try a CM10 build for kicks.
My first tablet had one dead pixel and it had this issue too. My second one is perfect except for this problem. It probably does have to do with the tegra 3. I hope its a software issue because this one is perfect except for that one problem. I'm not rooted nor unlocked and no force GPU rendering either. It only occurs on some apps with mine. Tapatalk, facebook and barely ever on chrome. I haven't seen it on any games or video nor on the home screen. There should be a place to report this to Google... I doubt they are searching through xda looking for every little problem. I've had this issue for a while and have been searching specifically for bit and just found it today. Also I never see it in horizontal mode.

I have this issue too and I think it's likely to be a driver issue as it appearance seems random and sporadic in frequency, but it's always really hard to tell about these things.
In any I'm guessing some people just don't notice this issue and thus haven't really talked about it. But it sure is discomforting seeing it.
I seem to suffer from this too.. Everything is stock on mine, no mods, no flashes no unlocks.. It appears to be worse when its been on for a long time.. Wondering if its heat related?
Occasionally, a horizontal or vertical line flashes on the screen very quickly and then disappears. Does anybody else have that? Is it anything to worry about, or does it not matter? Is it likely that a software update will fix this?
Thanks for any replies!
First, are you running a custom kernel or stock?

Damn it! I was seeing this on occasion and hoped that if I just thought I was crazy I wouldn't have to acknowledge it. Now I see it's not my imagination. It happens only rarely and it's really just a blip, but it is indeed weird. I just unlocked/rooted last night though so I'll have to see if it still happens now...
Always happens to me, really only noticeable on mostly white screens like in xda app.

First device had this issue, took it back (for many reasons), and have not noticed that little "subliminal" black line anymore.
Happens to me too, so far only seen it in the xda app, and in my browser while waiting for a Page to load that is taking a while.... I'm currently waiting for an exchange because I have a slight screen lift issue, but I doubt it will fix this black line problem, it is probably standard on these things. I guess I can live with it

I also get it a lot when playing an online chess game. It seems related to the apps used. Don't know what to make of it...

Could it be a memory leak or a GPU rendering issue as some have suggested? Many of us get this on the stock ROM with no developer menu changes.
I notice it too. I thought I was seeing things. It is not serious enough to give a crap though. I just hope it does not evolve into a worse issue.
It probably has to do with spotty Tegra drivers. I noticed it slightly on Chrome, but never on anything else.

I've seen this quite a bit also. Seems most prevalent for me when I'm using the GPS Status & Toolbox app from EclipSim, except in that app the lines are white.
I think you guys are referring to screen tearing. I have seen it a few times to I think in chrome. Pretty sure its not a hardware problem.

I get that in Tapatalk once in a while. I would guess its a coding thing and not a device defect.
Sent from my Nexus 7 using Tapatalk 2
I've not seen it mentioned, but I want to know if others have noticed.
So far all 3 of my CK60 devices have this. Originally I thought it might have been the app Thumb Keyboard. But my other two without the app display the same.
At about 1 inch from the right side edge of the display portion of the screen, a vertical black line will flash. I've only really noticed it while browsing. Not entirely sure it's not just an issue in Chrome, as I also have the stock ICS browser installed, but only use that to view flash videos.
Each has been unlocked and rooted, it's so random and happens so rarely that I couldn't remember to diagnose it pre-root/unlock..
Anyone else notice this?
Would like to know if something common, before erasing my unit to test clean stock.
I will get the random black line flash on some apps. Such as XDA, and chrome. Doesn't ever happen on a homescreen, or in game or anything.
Don't bother with wiping, it won't do you any good.
Same here. Think it's a software problem.

Yea I have the same problem also this is the second replacement.... screen flicker on the first now on this I get the screen flicker and lines on CK60 device
I flashed Motleys kernel for the performance but it also got rid of the flashing black line. I didn't really think about until yesterday when I realized I haven't seen it happen in a couple days now ever since I flashed it.

Flashing black lines?!?!?
Yep, same thing here. It isn't a huge deal, as it's just a split second flash. My only concern is that it may get worse as time progresses. I REALLY hope Google is working on some patches to address some of these Software issues.
Other than that, I am very satisfied with my Nexus 7, it's an excellent buy!
Google, please, you guys need to really tighten up your SQA department!

Make sure to read the instructions before doing this. It does take care of the black line for me I haven't seen it in over a week now.

Also over clocking isn't needed to get rid of the line flash. It is a nice feature to have. And for the GPU I would suggest the 484... Also be sure to give motley a "thanks" for his work.

I am seeing the same thing on my C70. I also sent in a support request to ASUS and directed them here. Will post back if/when they reply with something useful.
Noticed a horizontal black line flash across the bottom while in portrait mode. Happened while on xda a few days ago. Haven't seen it since

I don't see anything wrong either. Is there something physically wrong with the screen? Screenshots won't show that obviously.
Unless you mean that the screen is shifted to the right, then the screen is fine. If it is because of shifting to the right, it might be more of an app issue not hardware.

I've got this issue, seems to be software related for me. It renders parts of the screen (ONLY grey area in settings, only place where I can get this colour atm). I will try re-flashing stock roms and trying different things to see if this issue can be fixed.
It's the background gradient in the settings. A solution would be to find the image and replace it. You'll have to dig through some apks though.

I have three users configured and at times the tablet seems to lock up. But I can still pull down the notification drawer and setting drawer. I can touch the back, home, or multitask softkeys, or slide up for Google now.
But no matter where I navigate to, the N7 does not register touches in the "screen" area.
I have found that pulling down the setting drawer and tapping the user to "logout" and then logging back in immediately fixes the issue. Also toggling sleep/wake button and logging back in also fixes it.
Is this a known issue? Is this multiuser, software or hardware specific? Any solutions?
(I read back through a couple weeks of posts but didn't see this issue)
--- UPDATE------
Just happened again. But I left it alone for a minute, picked it back up and it was working fine. Perhaps this is app lag. The notification and navi bar work because they're systems but the screen stops taking input while it lags....(just a thought, I don't know how that stuff might work)
BTW I have a 32 GB N7, it is not rooted, and is fully up to date running 4.2.1

I'll have to learn how to get a logcat. But I was able to recreate the issue and get a video. I could only get it to affect settings and the play store but I've had this in the launcher before too. I don't think you can hear but tapping the screen was causing the touch sound.

No one has had this issue? I've only experienced it in Settings and PlayStore on me first and second user, nothing on my third user. Also noticed a litte lag on the homescreen too.
In the video you may be able to hear the touch feedback sound. The screen is recognizing taps but not doing anything. Sleep/Wake fixes the issue until you leave the app...
Guess I'll need to exchange my N7 and hope to get one without this issue.
Why did this get moved to Q&A??
Are Issues not discussed in General?
[SOLVED]
I was using APP LOCK on User #3 and that caused what seems like an overlay that prevented touch on users 1&2.
I sent this issue to the apps support. And will try to find a free app locker that is milti-user friendly.
