Screen Flickering? - Nexus 10 Q&A, Help & Troubleshooting

My dad's nexus 10 came in today and is having a horrible screen flickering issue. I'm just wondering if anyone else is having this issue and/or knows an easy software fix. It's frequent, full screen flickers, 2-3 times every 5-10 seconds.
Edit: Video of flickering http://www.youtube.com/watch?v=YulKn-2vYXk

I had something like that before I installed the OTA. No problems since.

Seems like a defective device. RMA it as it shouldn't' be doing that. Mine is running smooth with no flickers.

Unfortunately, we've gone through all the current OTAs. Definitely looks like we're sending it back.

Random vertical lines?

I've noticed that a random black line sometimes appears on my Nexus 7. It's very brief, probably on a single frame width ways on the screen, not so often, the closest I noticed were about 15 minutes apart, usually much more.
Has anyone else noticed anything like this? Could I have a faulty unit?
Wrong thread mate, q/a or general. I dont have any of these lines though.

I have the dev one from IO, but i don't have that. Sorry man
I have seen that on mine as well. Its almost as if the GPU missed drawing one of the lines on the screen. Pretty rare though.

What ROM are you running? I had this issue on SGT7, but switched to Linaro cookies and cream (motley kernel) and it went away. Smoother rom overall also.

Pretty rare but I've caught a few of those as well. Not so much bothersome as slightly worrying...
The last one appeared while charging but pretty sure I've seen them unplugged too.
Rare, but happened to mine as well. Just hope it won't get worse
same here

I have the same thing. My Nexus otherwise seems flawless.
I got mine direct from google.
Flashing motley's kernel seems to be the fix as of now.

Have you guyz checked if this happens in Bootloader and Recovery ? I did and I could see it there as well which had me worrying. My Unit is just a day old and I was worried if the device was plagued with faulty screen.
I saw this behaviour for atleast 6 hours and now it has disappeared ! I've seen these crap happening to LCD TVs as well, usually temp in the beginning but eventually it pops up forever !
Thoughts ?
i'm experiencing the same. but horizonal. but i know its a software thing..will be patched up soon.
waiting insanely for CM10

Screen warm up time

When I first load up my nexus 7, the screen looks terribly washed out but eventually becomes normal after a few minutes. In addition, bad screen ghosting occurs and gradually disappears over about a half hour. Anybody else experiencing this? Is this normal ?

I have the same problem :crying:
No, that's not normal... I bought 2 and neither do that. They're just like any other decent LCD device. Instant on without issue. Sounds like you got a dud.

Mine looks the same from the first second on until I turn it off. The only time it "washes out" (Tegra 3 "PRISM" Display stuff) is at very specific times when watching a video (including youtube) or sometimes playing games.
I have yet to see ghosting at all on the N7, I have seen it on previous IPS LCD tablets like my Nook Color, particularly if it decided to get stuck on while charging like it randomly would do. I'd go to another screen and the previous screen, most often the launcher, I'd see the icons for a few seconds on the new screen. But again, haven't seen this on the N7 at all.
I've worked with 5 brand new devices and have never had these symptoms. Not normal

Thanks for your advice. I've contacted Google and am returning this one in exchange for a new one.
I'm on the same boat Mate... :'( ... the problem is, that in UK return process is a real road through hell. I am thinking about accepting it as it is, mere 5 minutes of warmup time, but other than that - flawless.

Nexus 4 screen distorted/tearing

My wife just got the Nexus 4 the other day and she has problems with a potion of the screen becoming distorted very often. She said it usually happens at least once everytime she is using it. It's with no particular program or doing a certain thing, just random. The phone is stock still. I attatched a picture and you can see at the bottom of the screen. It's not always the bottom, sometimes it's at the top, sometimes bottom. She said it hasn't happened in the middle of the screen (yet). Has this happened to anyone else and does anyone have any ideas on how to fix it?
Don't try to fix. Get it replaced.

I had the same problem, but my phone was distorted all over. I returned the original phone they sent me. When I got the new replacement phone after just a few days it acted up the same problem. I returned it to Google and never purchase the Nexus 4 again. I'm glad they gave ma a full refund minus the shipping though. Right now I'm still searching for a good reasonably price phone
Just return it and ask for full refund before your warranty runs out.

Nexus 4 Display

Ok so today I wake my phone like I would any other day, but my screen starts to bug out. The display became all jittery and it was not uniform. Im not sure how to explain it, It was very distorted and started to flicker a little. I reset it 2 times and it began to improve. Right now, the issue is gone completely, but Im not sure if it will happen again. Also the phone became VERY hot after.
I'm running ParanoidAndroid Feb 03, stock kernel. I did use the Nexus 4 Display Control app to adjust the color a little bit, but not too much.
I've never dropped it and it never got wet or anything.
Any help?
How much did you adjust the colour by? There's a chance you adjusted it outside the 'safe' parameters.

annoying flickering and/or flashing

I'm having a very frustrating problem with my Nexus 7 (2013). About a week ago I started to notice the screen flickering and or flashing. I uploaded a video to show exactly what it's doing. I have tried to research and the only workarounds I found were to disable auto brightness and wi-fi optimization but both have been ineffective in solving the problem. The Nexus is currently running this kernel (razor-jss15q-factory) and was purchased around release day.

I have a flickering problem but it looks different than yours. Also my screen occasionally flashes black. I've also tried all the auto-brightness and WiFi tricks to no avail. The problem persists no matter what brightness my device is at and across multiple roms. I'm just about ready to send it back to ASUS for a replacement.
The flicker to black is not normal. Slight flicker at low brightness, more units have.

I have read about this somewhere
And you should return it. Flickering seems to be 'normal', going black is not

If JSS15Q or JSS15R doesn't fix it, I would return or exchange.
I returned the tablet to ASUS. After a 2 week turnaround time (including shipping both ways), I fired it up and immediately noticed the exact same problem (random flashing to black, plus some minor flickering). I called up ASUS again and inquired as to what they had "fixed". I was told by the customer service rep that they simply did a factory reset. They could offer no explanation why this was the only thing done.
So, back to ASUS it goes, again. This is frustrating.
