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.

I've never noticed my screen "flicker"; does it flash off and on again or what?

Yeah, please clarify what a flicker is... if it only happened a couple times then it probably is related to the apps or maybe a couple things going on at once.
If it is not a constant, consistent problem and had only happened a couple times then perhaps it isn't a problem at all.

I've never seen my phone do that. I don't do a lot of gaming or anything real intensive though.

please stop trying to mislead people and hype the problem. thanks

I get the flicker but it's definitely app related.
When using Google music app and going to lock screen, the " widget" sort of flickers and stretches throughout the lock screen

My screen flickered for a good 5 minutes and even a reboot didn't fix it. I think it's hardware related because if it was software a reboot would have fixed it. Could have been a driver glitch too but I'm pretty sure a reboot would've fixed it. My flickered a lot though saw a bunch of vertical lines and discoloration. Idk if that's what you're talking about.

I use Google Music a lot and I've never seen that. I just tried to replicate it and other than the usual CRT off animation I didn't see anything that I would construe as a flicker or flash.

If you hold your device in front of you with the screen on and look beyond it (i.e. over it's shoulder per say) you can see flicker. Works best in a dark room.
No big deal, but it's there.

I think its a big deal ...you spend your money for a working product..these issues need to be addressed..I thought I could trust LG again but dont think I can anymore

Is this a known OS issue, or are you just saying it might be?

This sounds like a refresh rate issue, which would be hardware, yes?

Sounds like one of those magic eye pictures. If you squint at your screen while holding it at a 45-degree angle in a dark room with brightness turned all the way down and jog in place...
I'm not sure how to replicate it based on what you said, but I still don't see any screen flicker.

Mine started flickering like mad today for the first time. I rebooted, but that didn't fix it. I started up a benchmark app and the flickering stopped after the graphics benchmarks ran. I had to RMA my first Nexus 7 with screen issues too, so I'm hoping this is just a software issue

I don't have this issue at all.

Weird Visual Glitches

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.

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.

[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...

Image Retention(?) On N4

I saw someone ask this in a nexus circle on G+ and though maybe it was just his device but a few people posted also claiming the same so tried it myself and noticed it also.
If you put your phone on max brightness and go to an app that leaves the logo on the screen like G+ in the upper left hand corner, imagine FB or whatever else will work the same, and stay there for about 2 minutes then switch to a dark screen(clock) the image is still visible in the corner. It stays there for a few minutes too, then its gone. Is this normal of IPS displays or even LCD for that matter? I mean its very circumstantial, you would have to at max bright and on that type of app for a long time and then to a dark screen to ever notice it but if you went longer under them conditions could it potentially burn in permanently?

This happens on my tablet (TFT LCD), but not on my Nexus 4. It shouldn't cause burn in, LCDs don't burn in

Hi there ! The one asking the question on G+ was me !
I'll post a video on youtube and open a poll about it here !
P.S. it seems that many people do suffer from the problem (cf. http://forum.xda-developers.com/showthread.php?t=2228013&page=4) Therefore I won't be making the video (I think)...

It happens to me all the time. Especially noticeable at night when using it in bed so it doesn't even have to be at maximum brightness.
