Screen tearing fix?

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.
Sent from my Nexus 7 using xda app-developers app

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?

Random "click" noise

Every now and then, when opening an app or using the system buttons at the bottom, a very short "click" noise comes from the speaker. I have my N4 on silent/vibrate all the time and it is not an operating system noise that's meant to be there because its random. The best way to describe it is that it seems like the phone is "accidentally" starting to play a sound then stopping because its realised its in silent mode.
Anyone else getting this? Views on this problem?
(It happened again as I was typing this, so it happens through the the keyboard key presses as well)

Maybe you have to turn down the media volume.

I don't have a nexus 4, but I do get that random click noise on my incredible s as well, and from many different roms. I am not sure what it is, though.

I get that click noise occasionally on my HTC HD2.
Running PACMAN 4.1.2 Jellybean at the moment.

I had this issue as well. I just turned off touch sounds and all is well.
I should note that I have keyboard sounds enabled and I do not experience the random clicking noise.
It seems to be isolated to the enabling of touch sounds, whether on vibrate or any audible volume.

I have the autofocus rattle issue as well. But I rarely if ever would shake my phone like that.
At this point I am just grateful that I got my phone, let alone got my phone earlier than projected. There are a lot of people that would love to hear the rattling of the autofocus on their N4.

Power Management
Ok... I think this is correct,
The audio chip like most other IC's are entering power saving mode milliseconds after you hear any audio so the small click is the powering up and down of the audio hardware... Many phones do this and many people don't notice it.
It's quite normal but if you have very good hearing it might bother some more then others.

Person on call does not hear me when I first answer the call

Every time I answer a call, the person on the other line does not hear me if I speak as soon as I answer the call. Is any one else having this? I have to call someone, wait till they pick up, say hello, hello. They catch the second hello every time. I can't help but think this is not normal.
This is not an issue of the case or bumper as I do not change the level of my voice when this happens.
I have excellent call quality. I do not have the buzz or the mute issue. I do not have any call quality issues at all.
I started another thread to discuss the issue I am having. Mods, feel free to move the responses into here and delete my other thread.

ok... I thought I was the only one having this issue. I have to say hello twice all the time. I just thought I was too quick to say hello, but it's been driving me crazy!
also, it happens regardless of the ROM I'm running. I guess I just have to get used to pausing for a few seconds when I answer the phone before saying hello... or just keep saying hello twice

I also had the same problem with my GNex on AT&T. I'm just now used to taking a breath after answering before saying anything.

I'm having this problem as well. I don't hear them neither do they hear me for about 4 seconds.

This happens to me on t-mo..happened on my GS2 as well. I noticed that if you wait until you hear the unlock sound after answering the call they can hear you.

Yes noticed in my nexus 4 after i got it, its kinda annoying, i want it fixed!
I also do have the buzzing in the phone, but its really low only hear it when theres no sound, doesnt really bother me...

HAHA I really thought I was the only one with this problem. Do any of you guys get random hanging up? Like you know FOR SURE you have good reception and that you never touched the end call but the phone hangs the call up anyway once in awhile.

having the same problem with the call delay as well, on ATT. the Gnex didn't do this

I have the problem but it is only for a split second so if I just wait a sec before saying something it works as it should.

Ok this is odd as I have the same problem and thought it was due to my using Groove IP or Talkatone. It sounds like it may be a hardware issue or a JB issue.

This is a very concerning problem. I hope it is fixed ASAP.

looks like a sw issue ....had the same on my Samsung Spica i5700 which was fixed by the devs on samdroid

Same issues! What the heck!

Very annoying. In the end it is a phone, what on earth it can't do it right on the basic function as a phone. Hope more people raise the concern and push Google to fix that. Otherwise RMA is on the way.

Yep happens to me also, hopefully will be fixed soon but not a big issue.

Buzzing Noise When Using Headphones

I've heard a lot about a buzzing noise coming from the earpiece, but whenever i plug in my headphones it makes a really annoying buzzing noise. I'm running AOKP Build 1 with Franco #28 kernel and the beats audio mod. I'm also using original Apple earphones. Any thoughts on how to fix this without flashing AOKP from scratch again? Thanks!

Is it like a actual buzzzzzzzz sound or a rapid click click click sound? If it's actually a click noise, it is the proximity sensor, and you have some other app constantly running it. If it's a buzz, are you running a custom kernel? Do you usually crank up the volume? Have you messed with headset gain?

I have the same problem. not rooted
and its not buzzing.its more like rapid clicking, but I don't think I have any apps that use the proximity sensor. idk what to do fam

What the f has the kernel to do with this buzzing noise? This is one of the stupidest suggestions I read in my entire life.
The noise is hardware related. You can't fix it with software.
Guys, you have to accept that the Nexus 4 ist a cheap built smartphone with a LOT of problems, and I am not talking about the bad camera or the bad display in general.
I am talking about the huge and small bugs, for example.:
- noise in earspeaker
- buzzing noise with headphones
- heat-problems (YES, the N4 actually HAS heat-problems)
- Sleep of Death (LED and sound is working, but screen is black -> restart with Power+Volume)
- not-responsive screen when unlocking/not able to answer a call because of this
- dark line on the left side of the screen (especially on grey backgrounds)
- (maybe I am the only one with this problem, but this happens very often) when I am trying to unlock the ring, the status-bar slides down
- WiFi and GPS problems
- and more
Sure, the N4 was really cheap in its price and the problems testify that this phone is cheap.
The parts they used are cheap (e.g. DA-converters, display (don't tell me that it is possible to adjust the screen colors), speakers, cameras, microphone etc.). Maybe also the engineers who built the N4 were cheap.
Before I bought the N4 I had a Nexus S. It was WAY better than the N4 in many points.
I always recommended the Nexus line to my family and friends. But after using the N4 for long enough I will never recommend it again.
It's a piece of crap with a well-meant OS and causes headaches.

Weird graphics corruption.

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.
gimpor, can you play gpu accelerated games? try please.
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
gimpor again,
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 :-/

I haven't found out anything further and it's still doing it but not as bad. It doesn't seem to happen to every stock phone so I'm guessing its hardware related, or at least something in software not playing well with this specific hardware. 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.
