So yesterday I was messing around with rooting and setting up CWM. It was quite frustrating, but not for the usual reasons: turns out that my Nexus 7 likes to turn the backlight completely off during parts of the boot process (the google and X logos) and always in CWM so it looks like it is off when it in fact is doing something. To be able to see anything I have to shine a very bright light (using Torch on my phone right now) on the display. However during normal usage, there are absolutely no issues with the backlight.
Any Ideas?
I can try to take pictures of it later, but I don't have a very good camera.
Bump. Anybody?
Same problem here. No idea why it happens.
I contacted Google and they're going to replace it.

Return it to stock bootloader and ROM to rule the changes didn't introduce issues.
I did, it's definitely a hardware issue
Sent from my Nexus 7 using xda app-developers app
I don't mind it actually since it only happens during boot. Not much of a problem here.

If you intend to flash custom roms it's a huge problem lol.

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.

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.

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 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...

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 get that in Tapatalk once in a while. I would guess its a coding thing and not a device defect.
Sent from my Nexus 7 using Tapatalk 2
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.

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

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.

Hi Guys
I seem to be suffering from a issue where the touchscreen has a dead spot.
Now I had an earlier issue that caused all sorts of issues with screen responses - ultimately ending in no response unless I hit the power button to lock and then unlock.
That problem lasted about a week and then stopped - my thinking is that there was an app update that solved it.
Now however the issue has resurfaced (seemingly after other app updates) but it is a dead spot roughly where the first notification would be on the notification draw. Any ideas as how best to find out the cause of the issue, or a fix?
I've included screen shots showing the touch trace.
Cheers for any help

I can't help you but with some custom rom there can be a bug with it until I make some setting changes to the Nav Bar, but otherwise I don't know.

What I don't get is why it went away after the first time.
I don't really want to factory reset if I can help it.
Is there a way to look at an update history for all your apps? Then I can pinpoint the offender.
Sent from my Nexus 4 using xda app-developers app
I've found a solution.
After factory reset and safe mode not helping I came across a comment in another thread.
You have to Disable HW Overlays and Force GPU Rendering. Now its not perfect and can have an occasional fit but does seem to solve the issue
