nexus 7 screen flickering

So this only Happens when I'm on Google chrome and I've noticed that ocassionally that the screen flickers, its not crazy annoying but definitely distracting. Have any of you had this problem?
Hopefully any of you aren't epileptic.

Hopefully the next update will resolve this problem.

so set and wait.
So I should just wait for a fix and not return it over and over to try to find a good one. It has a year warranty.

I see it too!

I turned off automatic brightness and I think that solved it. I think it was flickering when it was changing brightness.

its still there with auto off.
And with the brightness up but it so slight u have to be ocd like I am about my stuff to see it. But its easy to tell its not hardware because games like sonic CD are beautiful.

It happens to mine when its on the lowest brightness setting of when "auto brightness" is on. For now I've just set the brightness to max so I don't have deal with all the flickering.. for now.

With my settings set to Automatically lock (immediately after sleep) and power button instantly locks with a visible patter screen lock, my Nexus 7 on wake-up [pushing the power button immediately] either right after an invalid pattern code (where device then sleeps) or waiting a few seconds with no activity until the device sleeps (where the Nexus 7 fades to a black screen) will have a delay in bringing up the lock screen OR sort of flicker presenting some sort of black and white bar lines background at the bottom half of the screen for a split second before bringing up the lock screen. Is this normal or it is in fact a defect?
Thanks in advance!

Not sire about that I have seen it in 3rd patty apps on all devices before. But the flicker we are seeing is like it changing the brightness up and down.

As does mine. I think people think it goes away when not on auto, because the "low" setting is about 20-25% and auto will often bring it lower than that, making the flickering worse.
At medium brightness the problem is almost, almost, non-existant.
It's also not just in chrome as some say, just most noticable on chrome's white backgrounds. I've noticed it in any app with lighter, brighter colors. I just exchanged my Nexus 7, and the new one has the exact same problem. This leads me to think the software problem is the most correct answer.

I get it every once in a while. Full brightness set, no automatic. Ill wait for a fix, doesn't bug me too bad.

I suspect it to be a software problem because in game it looks great. Plus in a new device like this software problems go with the territory.

And mine as well I noticed my screen flickered when my batt was getting down to 10% and my brightness level was at about 1/3. But now its charged and I don't see it flickering yet. I don't know...with Chrome having a bug (lags when scrolling) and the flickering screen...I may be returning my unit? I really hate to because aside from my issues, it's an awesome device!

Don't take it back they well fix it with a update.

Lines flash on screen

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?

I have not rooted my device. I have flash installed and Iplayer, but apart from that all my apps come directly from the Google appstore...

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 get it like once every 10 hours or so and only when using xda app or chrome for some reason.

Yep, I see it with tapatalk. Haven't noticed it with anything else just yet.

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

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 haven't noticed it at all on the nexus. I have had this issue on my tf201 though.

Hmmm... seems this thread should be combined with the other regarding the same issue: http://forum.xda-developers.com/showthread.php?t=1791281

Yeah I get this too I'm hoping its a software issue it doesn't happen often but I seem to only notice it on tapatalk or the Facebook app. I haven't seen it on games or videos.

I see this on occasion with the xda app. I haven't seen it all using anything else. I'm no overly concerned.

I get that in Tapatalk once in a while. I would guess its a coding thing and not a device defect.

Screen problem

OK, I've only noticed this now, but as you can see by the image, the right side of the screen seems like, well I dont how to explain it. Anyone know what it is, possibly how to fix it?
Sent from my Nexus 7 using Tapatalk 2

I think the word your looking for is normal.
Lol
But seriously i dont see anything wrong
Sent from my MB855 using Tapatalk 2

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.

Its a Google software issue.. Alot of people have the same problem even if they don't realize it

If you look closely its on every Nexus 7, it's just Google being weird with the gradients.

[Q] Nexus 4 weird display issue

I got my Nexus 4 yesterday, and just today I've noticed that when in dark screen (locked, or simply the settings page) and outside of the house I see kind of weird black lines on the whole display screen, going form top to bottom making some 3 small square shapes after the others all over the display, can be obviously seen when display facing bright sky outside in almost any angel, but in room light barely can see them with certain angels.
will make a photo of it asap.
p.s. I've never seen a notification light yet on the middle bottom of my device.
Anyone same "problem" with display?

Its the digitizer.

I can confirm that its the digitizer I too have found that with this phone it is very easy to see even with weak light I see it when I get the right angle. It looks like you described but the vertical lines look more like dots arranged neatly than lines on mine.

Just noticed the same thing on my device. Thought I was tripping out maaaaaaan
Sent from my Nexus 4 using xda app-developers app

Its the digitizer, its normal. I think its because of the "zero gap" technology thing ; the display and the digitizer are right below the glass.
As for the notification light, download Lightflow from the Play Store. Works great.
Sent from my Nexus 4 using xda app-developers app

For the notification LED, make sure you enable the " Pulse notification light" option in Settings->Display. Using Lightflow on top will give you lots of customisation options though.

I am now noticing the same issue in my nexus 4. If it is because of zero gap technology then why it is not there in iPhone 5 and other phones which use this technology?
I also notice that my brother who got the phone some time in November 2012 is not having this issue. I got the phone in Jan 2013...is it issue with only the new lots?
What google and LG are doing to address this issue?

Its the digitizer. I mean seriously why are y'all complaining about that, its normal.

[Q] Dark line on my screen.

One thing that annoying me on my nexus 4. You can see on the left of my screen, straight dark line from top to bottom. I haven't drop my nexus before. It appeared on dark colours especially grey colours. For your info its start to appeared when 10 minutes screen on after about 20 minutes screen off. Is it normal? Anyone here have the same problem?

Holy damn. I was just about to make a thread. But mine can't be screenshot. Its seen just like you said and I can flick the different home screens and it stays in the left I've flashed back to stock and still there. Been a week. It got less noticeable when used less. I'm wondering if its because I'm near a big subwoofer in my living room. I know TV used to do this like a bleed line. Have you heard any data yet??? I will send mine back. Please let me know...
