Weird Visual Glitches - Nexus 4 Q&A, Help & Troubleshooting

I've been getting some static-like glitches on my N4. Even happened on stock up in the status bar. I was unlocked and rooted but running stock everything. Now I've seen the Navigation bar glitches a few times. Still on stock ROM but with Franco Kernel. I also had some of the weird battery issues resulting in the red led of death. It always recovers (eventually) but kind of strange. Anyone else ever see this sort of thing?

The only odd thing I've seen is a small red dot in my notification bar at the top left of the phone. I know it's a software issue because I screenshot it when it happened. If I touch the bar it goes away.

The first post reminds me of faulty ram.

Does it only happen when you use Reddit News?

I've seen this but only when I'm using SwiftKey. I thought it was a bug in the app.

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?
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.
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?

[Q] Random vertical "black line" flash, not permanent, nor dead pixels?

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.

Thanks for chiming in guys, appreciate it, it doesn't "really" bother me, but it is a "glitch". Good to know.

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

4.2 Grey Background Artifacts

Ever since updating to 4.2, I have these grey artifacts on grey backgrounds when dialog boxes appear... such as the one attached in my pic......
Not sure why more people are not bringing this issue up, but anyone heard of anything like this, or can confirm to experience this?
You mean the partial discoloration? Yeah my Nexus 7 has that as well...seems like Google messed up on the coloring or something

So more people would notice it and discuss it on Google bugs so it would have a better chance of being fixed in the next update, which it will be now.
Ever since updating to 4.2? What do you mean? Your phone should have come with 4.2 already installed.

It looks like the grey is dripping like paint down the back of the dialog box.
I am surprised you even noticed this. On my screen it's really faint. I had to hold it right up to my face...
Its more prominent on my Nexus 7. And I meant that this is a bug that arrived with the 4.2 update, because my Nexus 7 got this bug when I upgraded to 4.2

[Q] Nexus 4 shows screen artifacts

Sometimes but not always my Nexus 4 wich has battery drain problem (msm_hsic_host wakelock) shows artifacts on screen.
It does not happen always its stands for few seconds then it disappears.
Lastly it happend me today when i was using GoogleNow and it showed on search bar then few weeks ago it showed on onscreen buttons.
Does anyone seen artifacts on their Nexus 4 so far that has battery drain issues or any other Nexus 4???

I'm having a similar issue, where at times, areas look almost pixelated? I can't quite describe it. Almost like I can see the outline of every pixel in a certain graphic, for example the Google search bar, or an icon.
Yes and sometimes shows on other parts of screen

Colors changing on s4, not adapt display

So yeah does anyone else have this issue? My s4 colors tend to get warmer and like have a green tint when the keyboard is pulled up any keyboard for that matter in any app with adapt display on or off and auto brightness off or on. Like the status bar turns greenish too. It's so strange.

Yes. But only when the keyboard is up. The color of the whole phone gets warmer

interesting.
I want to see if someone else can test this. Open up or even reply and look at the status bar and tell me if the black becomes like a greenish tint as well as the whole screen. Then close the keyboard and watch it change back to normal.

I see it change a slight bit, but my face has to be pressed up against the glass when opening the keyboard to even notice. Is this really an issue?

I have exactly the same problem on Verizon S4. It really bothers my eyes as it seems to be changing the white balance / tint simply based on what's on the screen all the time. I have of course turned off all options that have anything to do with automatically adjusting the display.
I have the exact same problem with my GS4 international version. The problem gets even worst when playing a youtube video. The colour of the youtube video and the whole screen changes when the status bar is present and when it is not. The whole screen becomes reddish when the status bar is present and greenish when the status bar is not present. Any help on how to disable or fix this?

No but people seem to not realize it's even there. It's built into touchwiz. Only goes away in like cyanogenmod or something. But I'm sure it can be fixed if a dev wants to help so let's all keep this rolling. Anyone else notice it?

After I noticed it a few days ago, I think it is ok now, at least not as bad as the first time i saw it. Youtube video seems to be ok now with very very tiny bit of change in colours and contrast compared to yesterday with the same video. I think it might just be some bugs in the software. I did try restarting it many times yesterday and also disabling auto brightness, auto adjust screen tone and adapt display and that didn't help at all but now it's just kind of fixed itself
I just realised that this only happen when the brightness is set at a very low level. The effect is less noticeable when the brightness is high.
Yes so it's throttling the display to save battery and such
Does flashing cm10.1 fix the issue?
