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.

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?
Sent from my Nexus 7 using xda premium
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.
Sent from my Nexus 7 using Tapatalk 2
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?
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.

Just wondering whether the touch sensitivity has been fixed by a ROM?
Is it a hardware or software related problem?
Thanks
Sent from my Nexus 4
I think it's more hardware.
Sent from my iPhone using Tapatalk
I think it can be improved with software.
It was done on other devices.
For example on the Galaxy S2 it is possible to increase touch sensitivity up to the point where you can type by just howering over the screen without even touching it.

Check this out, comment 40 and 42. Looks like its definitely software side, I'm sure google/LG will eventually fix it.
Thinking about the N4 as a secondary phone but I played with one in the T-Mobile store and noticed that pinch to zoom seemed to be pretty unresponsive and disappointing and that's putting it lightly. When pinching to zoom it felt as if I was moving my fingers through quick sand. It was as if my fingers had to literally transverse half of the entire screen before the phone started to react. Can anyone else confirm this? Like I said, this will be my secondary phone and my primary will be an iPhone 5 so I will going back and forth between the 2 phones often which will make the poor responsiveness even more noticeable and bloody annoying since the iPhone is very responsive and accurate in this department. So now I'm rethinking my purchase of this phone. Again can anyone confirm this??? Thanks
mine doesn't do this. it is very responsive.. are you talking about having to go out farther when zooming in? i think they designed the zoom in to occur after your fingers have spread over a certain distance so you don't accidentally zoom in when you don't mean to.
Its like people are just finding reason not to buy this phone cause it has real issues or they just like to complain....personal I think your all crazy . My coworker got his nexus 4 last week and its ****ing awesome the camera in HDR mode is amazing the data speeds are top notch and the screen is responsive. I don't know it everyone and there mama was playing with the display phone at T-Mobile ,but here a story I was playing with a Gs3 at T-Mobile and found pictures of a girls ***** on it .

There was another thread on this yesterday - this is actually Google almost certainly designing around someone else's patent on touchscreen usage. They probably figured that what was going on in older versions was too close to Apple's or someone else's precise method for interpreting multitouch input, so they designed something effective but different enough to avoid litigation. There's a reason why neither Apple nor Microsoft have sued Google directly over Android - Google designs around patents pretty well.

I hear ya, but even still it'd pretty annoying and making me think before I buy. Honestly I'm a stock app kinda guy. I like the stock apps, I actually want to use Chrome but I can't, I want to use the stock gallery since it would be more integrated but I can't without this bug/feature this will also make using Google maps bloody annoying more than anything as when using maps there is a lot of zooming in and out. I'm wondering if other ROMs have this issue with the N4 or not.... Hmmm... That would be an indicator if there was more of a real issue/hardware level issue or not. Wondering if Cyanogen, Paranoid, or AOKP would have the same issue...
this is such a moot issue based completely on software filtering/calibration of your touches. Capacitors are hyper sensitive to touches, so much so that you have to tone it down and filter out all the noise... You can easily go into the software and figure out where the pinch-zoom controls are and fix them...
I am running codefireX's build and my pinch to zoom works perfectly in gallery, chrome, maps, camera. Registers my touch input no mater what I try.
If this is a deal breaker for you, I would be more worried about thermal throttling issues tbh... Those are actually hardware related.

So you're saying right out of the box you can go into settings and configure pin h to zoom to react immediately rather than after transversing half the screen before it starts reacting?
Well, this is xda developers where we hack software and improve it for our own uses. Its part of the fun. You would have to get into the kernel for that

Hi. I have had this Nexus 4 for about a month and it has does some strange things with the graphics on the bottom bar of buttons. Please see the screenshots attached. It can happen every few minutes and as soon as I touch the screen it will revert to normal again.
Is this something that is likely to get fixed with an update or a hardware issue?
I can't find anything on the internet referring to the same problem but the sales guy in the local carphone warehouse has a nexus 4 as well and said his does the same :-/
Anybody know what is causing it.
Completely stock BTW oh and as you can see. Pressing the hardware buttons for a screenshot does not fix it. Only touching the screen.
Sent from my Nexus 4 using xda app-developers app
Wow.. thats not normal! I would look into RMA'ing that sucker!
You could try using a toolkit to reflash stock to see if that helps, however you will have to unlock the bootloader, flash stock rom and then relock bootloader, then you just go into settings and do a full reset to hide the developer options then you will be stock. The toolkit I use is this one http://forum.xda-developers.com/showthread.php?t=2015469 and its awesome just follow the on screen prompts.
I'm quite sure that this is a software issue, since hardware issues can't be captured by screenshots obviously. I'd recommend flashing it with whatever you like and do a factory reset. You can restore all apps afterwards ofc (use Titanium Backup for example).
Best regards!

That only means that it isn't an issue with the physical screen. It could still be an issue with the GPU or other hardware, since various hardware is used to create that software image in the first place.
I have seen exactly this sort of picture posted in at least one thread before on here before, though that might be hard to find on a search.
I would also recommend reinstalling the ROM and if it still happens then it must be hardware. I strongly suspect that it is the hardware.

hmmm, and the gpu just decides to screw up down there in a perfectly aligned rectangular shape that happens to resemble the navigationbar? i think thats unlikely.

its probably googles weird 4 layer stuff. thats why disabling hw overlays fixes it. same guy that screwed up the kernel colors that merged it into 4.2.2 btw. : P

hwoverlay is not permanent, a reboot unchecks it. try this
replace persist.hwc.mdpcomp.enable=true
with debug.mdpcomp.maxlayer=3
in your build.prop
or in the worst case persist.hwc.mdpcomp.enable=false
Its much better but still not fixed. Only done it once in about 8 hours whilst playing a solitaire game. I will try the other suggestions when I have decoded them into English :-/
I have not found any games that don't work yet, bad piggies etc. Seem to work okay. Would they be GPU accelerated?
Once again thanks for the assistance with this, it does get rather annoying when you show someone your phone and it's all garbled.
It still does this though :-/

Mine is a 212 so they may have changed something on the later ones. I got it from Carphone warehouse on the UK as they were the only ones with stock. I had it changed already as the first one I got was DOA. I think it's going to have to go back if I can't get it fixed soon.
