Hi guys, I was wondering if you could help me where Nexus 7 customer service failed.
Basically, my stock wallpapers are really grainy, check the screenshots to see what I mean. They weren't when I first switched the device on, only after a few days. I've attached the standard jellybean wallpaper we all recognise because it's the one where the effect is most pronounced, try looking at it on your own n7 to see the difference, colours should be smooth rather than grainy.
I've done a factory reset, as advised by n7 customer service, and the problem remained.
Just to clarify something important; the screen itself is fine, and setting other wallpapers is fine too. The graininess occurs only on the stock wallpapers both when set as wallpaper, and when viewed in the wallpaper picker. This made me think that perhaps the wallpaper files themselves were somehow corrupted?
I'd really appreciate your help, I'm not rooted, and would rather stay unrooted if possible (blasphemy, I know).
I guess it has to do with the brightness of the screen.
Switch the brichtness higher and the grainy effect is gone

@dendirk Tried it, no luck there.
Also, the screenshots do not take screen brightness into account.
Why not reflash the stock factory images. It requires unlocking the boot loader.

This has been confirmed look at the washed out screen thread we all have the problem its a tegra problem it happens when you play a video there is a fix dont know if it works but i think this will get fixed soon ota update.
all nexus 7 wallpaper is like that. try applying a custom wallpaper and the grain is then fixed.
On second thought, yes. I think they are meant to look that way. Even on my Galaxy Nexus they look like that.

Does anyone else have this problem with their nexus 7? I just got my nexus 7 today but I noticed that the backlight seems to flicker randomly
It doesn't look like much in the video but it is very noticeable and gets annoying when you're reading an ebook like i was.. Here's a video showing the problem.(It's near the end)
VIDEO LINK: h**p://db.tt/28eD0NLk (It happens around 9 second in) (change ** into tt)
For whatever reason this forum would not post a video link to show the problem.. for those who wants to know what it looks like please PM me..
But basically the screen flickers randomly ..
Is this a software problem? Should I go back and get it exchanged?
I don't see a video

I think its different.
Mine flickers no matter which app I use..even on home screen it flickers..
Also this forum has the most ridiculousspam prevention method..5 mins between posts + no link ? WTF
Its because you are new, we get a lot of trolls
Does increasing your brightness help?

I've had a similar problem as well. It seemed to happen to me on auto-brightness when it was changing the brightness level. I can't say for sure though, just my observation.

I havn't tried it yet..do we know if it's a hardware problem or software?
I just got it today so I can still return it if it turns out to be hardware
We really dunno at this point, but we are speculating software since both HTC One X and TF300 had similar problems and were fixed with firmware updates. Also someone switched it three times and all of them had this issue. Also try to run the screen in a pitch black room and tell me if the screen flicker is there. I may have a theory but need some other people to see if their units are behaving the same way as mine.
You can still post the link when you alter it a bit, insert a few *** into it, for example.
I turned mine on as soon as I got hold of it, no flicker, managed to go through and set up things, powered off and left to charged.
Coming back to it the screen would appear to turn on and off randomly, I thought it could be an app controlling a proximity sensor (I have one on my phone and I was EXTREMELY tired!), when I took it into the light there was no change.
I found that shaking it would help it flicker on and off at all intervals but didn't fix it. In the end I just started pushing random areas on the back, just before the issue went away I pressed around the bottom left quarter of mine and haven't had an issue since!
Glad I wasn't the only one with the problem though and would love to actually find out what it was.
Hope this helps!

Try this video,
h**p://dl.dropbox.com/u/13153603/Videos/VID_20120715_100253.mp4
it is using google map and you can see the constant flickering.. It doesn't look very severe in the video but it is actually very noticeable and annoying
I have the same issue with mine. It only seems noticeable when I have the brightness set to the lowest setting and on a page that is predominately white. I don't think it's the proximity sensor though, because it happens both when I set it manually to the lowest setting and when I'm in the dark and the tablet sets the brightness all the way down itself. Hope the next update fixed this, because it's really annoying!

Seems like only a small portion of nexus 7 owners are reporting this issue .. I think I'm going to return mine ...

I first noticed this flicker in a darkened room, so yes, it is definitely something going on. I'll try disabling auto-brightness to see if that matters.
If anyone else has info about this, please share!

I can attest that the flicker is ever present in a pitch black room as well.
Like this?
There are a few videos on youtube, but i cant post links but if you do a search you can find it
I noticed a flickering in chrome yesterday. But only in chrome and only while the page is rendering after it fully renders no more flickering.
Everyone turn off wifi and I guarantee it will go away. It happens when using wifi which makes it hard to believe that a software update can fix it.
Hey everyone, so I set smart dimmer off but it doesn't help. I turn on my tablet and it's always washed out and quite a bit of ghosting. Anyone know any way of fixing it?

Same here. I sent it back. Ordered a new one a couple of weeks later from another place, same issue.
There are many articles and threads about this problem, but unfortunately Google and ASUS seem to ignore it. And even here on xda, people get defensive about their Nexus 7 and downplays the problem, attacks DisplayMate for scientifically illustrating the problem etc.
It annoys the hell out of me because I _want_ to love the Nexus 7, I _want_ to _want_ to keep it. It has great hardware, great software and even the IPS screen is great, but unfortunately the end result is a display that is seriously miscalibrated. The simplest calibration tests of black level, shadow detail, white crush and saturation and intensity (especially of the green primary) shows the major issues. Worst, it is obvious in daily use all the time.
I probably will end up sending this second Nexus 7 back as well and buy something with a half-decent visual experience.

I already have PRISM disabled. It helps a tiny bit but does not begin to solve the problem at all. Gamma, white crush, green saturation and intensity, contrast etc. still looks like something from 5+ years ago.
And there are a billion threads about this on the internet. I wish Google would take it serious, but...

I don't know if I go lucky but when I went to safe mode and turn my device of overnight then in the morning I no longer experience this problem. Note I experienced your problem for 3 months and just yesterday the issue was resolved simply by doing what I stated. Good luck let me know what happens

I recently installed cm10.1, and noticed banding on the settings menu, and a weird patchiness in certain menus.
I'm not very good at being descriptive, and pictures speak a thousand words, so please see attatched.

I assumed this was a cm10.1 bug, what with it not being finished, but turns out stock 4.2 does this.
Are there any remedies to this?
Bump
It is common, not sure if it is a cm10.1 issue, or a nexus 7 issue, or a 4.2.1 error
Sent from my Nexus 7 using xda app-developers app
Doesn't seem like too big of a deal, but you could try installing a theme and see of that fixes it if you're bothered and on cm10.
Turns out its by design implemented by google, its simply a terrible image created by them. This guy has a fix though http://forum.xda-developers.com/showthread.php?t=2052598
xda n7
Its by design?! They really dropped the ball on 4.2.
Thank you for the link to the thread.
I noticed this as well and at first, it had me worried my screen had internal injuries or something.
Then I turned it to landscape and the issue rotated with it, so I was like "Oh, that's strange."
It has to be a 4.2/CM10.1 issue, as my phone (though less apparent) has it too.
We all know that some of the color looks washed when we watch in a diff angle , also the head on looks sometimes may not look great since BE2 is not applied all time .
not sure if this works as I dont have a rooted phone ( dont plan to root till 4.2 ) can anyone test this on their rooted phone and post results and reviews please?

Try screen adjuster. Does not require root.
Tried it. It doesn't work. Gives an error everyone you try run it
Sent from my C6603 using xda premium
It won't work more than likely because it is based on the Nexus 4 hardware.

No error on mine(stock rom). However not really good at adjusting the screen color.
Adjusted as per image. Picture shown the with and without.

If you just want to deal with the view angle problem, set the system brightness higher (80% or higher), and set the brightness of the screen adjuster to 50%~70%, nothing else. Then the view angle will be amazing, but you will also find very little blue tint when displaying white color

Wow, call it placebo or whatnot, but it seems as though it helps to some extent! (maybe it's just me) O_O!

yep that helps to a certain extent thanks for finding,,
What I'd like to see is for you to post your reviews/comments comparing 4.2.2 vs 4.3. Tell us what the differences you've seen, the good the bad and so on. If there's a specific app that works awesome now because of the new graphic update, what apps are having issues, etc.. Have you noticed a difference in the pictures taken with the camera. I'd like to see this in here so those that are updating will be able to see what others in the forum are experiencing since their upgrade.
I find that my phone boot faster compared to before, which is always nice. I've taken a few pictures and I see a modest increase in quality and the new menu is easy to use and make sense, style-wise. I've heard some complains about the Netflix app, going black and such, but I've had no issue with this myself. I did have to do a cold boot this morning for some reason but not sure if this can be attributed to the update or not.

I find my phone alot more snappier while opening apps and doing stuff, as if 4.2.2 wasnt snappier enough
The new camera is really good in terms of usage and pictures too i must say...thr use of flash has improved from before
T9 dialer functionality is pretty awesome...and completes the phone app...dont need 3rd party dialer now
All in all, it may not be a big update...but all the things are cool except that mx player pro isnt working, also crashed my apex launcher, rest seems to be working fine
I really wanted the wallpaper displayed on nexus 7 2013...but no luck there..
