Steps to reproduce for ALL tablets.
1. Weak WiFi signal.
2. Backlight dimmed to under 30%.
3. A program that constantly accesses the net. Such as Google Maps.

If you have a very strong WiFi signal (All bars lit up) the Nexus 7 will not flicker.
That is why the flicker went away on my Nexus 7 last night. I was sitting in a strong signal location.
When I went upstairs I had a weaker signal and that is when the flicker was noticeable again.
So, that tells me the WiFi chip in the Nexus 7 is a cheap piece of crapolla.

I think we have a few things going on..
- There is flicker from truly faulty displays (lines of pixels/panels going out, fluttering, etc.)
- There is flicker from Prism or some type of dynamic contrast.

Hi all, i can confirm that it's somehow software related. What i mean is not that the hardware is OK, but that software can fix it.
I thought it's somewhat related to the Nvidia Prism Technology inside the tablet, trying to setup the screen and optimizing something. It is related to this in my case. I rooted and used an app on the play store to stop that feature. Now i can tell you that both 4.1.2 and 4.2 are flicker free. Somehow on 4.2 this process is much more aggressive and i think that Prism is on all the time, not only when you are watching videos, even on the homescreen.
PS: ...the Prism Feature optimizes the screen, and it really saves battery...but you have some screen problems.

However, many people have also reported disabling Wi-Fi optimization removes the flicker. To do so, open the Settings screen, tap Wi-Fi, tap the menu button, tap Advanced, and uncheck Wi-Fi optimization. Of course, this will also impact battery life.

Pictures are dead but the claim is that scotch tape on the WiFi antenna solves the flicker (some disassembly required). This claim is refuted, but seems to work for many.

So I was very lucky to be able to go to Google I/O this year (don't hold it against me).
My Nexus 7 flickers horrifically when the brightness is at minimum and Chrome is loading a new page. I'm hoping someone (or a few of you) can reproduce this to make sure I don't have a lemon. If its something correctable by an ota update I'll keep my unit, but if not I only have tomorrow to exchange.
Anyone else experiencing this?

Can you take a video? I haven't heard anything like that. If anything it sounds like a hardware problem.

My wife and son are asleep in the room so I can't do a video. I found another thread about the One X getting an immediate update to cure screen flicker. I'll probably talk to the Googlers about it tomorrow, but I wanted to post a thread to be available for future queries.
It seems to be a common issue with Tegra 3 devices. HTC fixed it pretty promptly so I expect Google/Asus will get it fixed even soon if it does turn out to be a common problem.
This is an issue with Transformer Prime as well, maybe Nvidia still hasn't fixed their drivers. It has come and gone with different firmware updates, most recently it's back again... Seach for "transformer prime screen tearing" for videos of it. Does it look similar to what you saw?
So the connection is the Tegra 3, then. Good to know.
My issue is not like the screen tear. Mine is the entire display flickers like it was backlit by a candle. I'm using Thomas Edison's tablet from the 19th century.
Also, it ONLY happens on page load in Chrome and with brightness below about 10% on the slider. I'll talk to Google today and relay what comes from that.
Why don't you just exchange it?
Sounds like a possibly defective backlighting module... I'd exchange it.

It sounds very similar to the HTC One X issues which were fixed by a software update. It's hard to say without seeing the screen flicker though as there seem to be various screen issues that people refer to as "flicker".
While you are at it, test if USB storage works on your N7
The HTC One X had the same problem.if not worse. Flickered on any brightness level on a grey background.but HTC fixed it so it is a very good chance it is software issue with yours. Give it a few months first?

So this raises the question: Is it a flaw with his specific N7? Or is it s flaw with all of them? I guess we'll have to wait and see.
so only 1 person out of 6k reported this issue?
lol
I got 2 in a row with the identical issue. They mentioned 2 or 3 other people came for the same issue. But, I'm happy to report that this 3rd one has no issue! Good to go, and loving it.
I think its problem with ICS/Jelly Bean for tablets

Does your Nexus 7 from google io take an extremely long time for screen rotation? I picked one up at the conference and did not open until today after the event ended. My unit sometimes takes as long as 30 seconds to rotate from landscape to portrait or vice versa.
FYI I have not tweaked or modified this tablet in any way. Just performed the software update after I was prompted to do so after setting it up for the first time.
Hello all,
I'm experiencing this issue since I got my phone, I've experienced it on all roms including stock everything, google edition rom and android revolution HD.
The problem goes like this... I'm using an app, all of a sudden it freezes, I can't perform any tasks on it. I try to force close it and reload it but it becomes frozen. I put my screen to sleep and the device never wakes, only the capacitive buttons do. Then the phone forces a reboot after about 30 seconds.
Sometimes, I try to wake up my phone and it never wakes, it seems apps or something within the android system is frozen.
I have gone through firmware, factory resets, roms and kernels I don't know of what else to do.
Anyone else experiencing this?

Didn't receive until June 3rd. What do you mean take action, I mean the phone has been bugged out since day 1 evidently. Thoughts? I'm still scouring to see if it's a rouge app.. can i log this error somehow. I tried alogcat but no luck.
Can any developer chime in?
Found this on android forums, seems to be the same issue http://androidforums.com/htc-one/716007-freezing-lock-up-issues.html

Don't worry. Happened to me too. Just give it more time, it'll eventually start draining. It only happened the first time I took it out of the box. Maybe the battery has to calibrate or something.

Unless of course it is being powered by your awesomeness.
so lately in morning phone will run okay...as the day goes on and as the battery drains some it will become almost unusable . 5 to 10 second freezing in lag when switching or opening apps....lock screen freezing black screen etc. had the phone since release and didn't have e problem until recently. Makes me think it may be hardware or an app ... Is there an easy way to see what is slowing phone down? Reminds me when pc has malware just lags so slow. Any ideas?

Not that I know of. You can grab CPU-Z and see what your CPU load is. If its high, then its definitely an app.
Also keep in mind if the phone is hot, it runs slower. This is true of every smartphone out there and the higher end ones suffer from it more. I've only managed to slow this device down during an extended game and that was due to throttling.
Mine started doing this the last 2 days also!!!! I was gonna take it back.... I don't think its CPU load, my phone does not get hot. I did use 4k video record yesterday, wonder if that had something to do with it... or an update to an app.

The phone doesn't have to feel hit to throttle.
Just thought I'd throw my hat into the ring on this one.
I had the same issue here after the last update. A hard reset sorted this.

By some stupid chance, do you have the widget that shows the time, weather, battery and such on your homescreen???
I just noticed this on mine, when the phone lags, the animation for the weather does not happen, as soon as it does, the phone will respond. Its like its waiting for the widget to update before anything else. So, I removed the widget and the phone is much smoother. No more lag. Gonna still have to try it for a few more hours, but I think that's it (at least for me).

As for my situation, I switched back to dalvik and used a cleaner program from the play store and seems to be running much better now.... I'll be interested to see if the findings from removing the widget hold up for the rest of the day for u

So far, about 2 hours and no lag!!! It was an instant fix. I had the lag, removed it and presto!! Gone!
Edit/update
I have had 0 lag ever since!!! I am 95% positive that the widget was the cause.

Yes man!
I just received the OTA notification 20 minutes ago and I installed it immediately! Now the tablet is updating apps, still a few minutes..
I have LG G Pad 7 WiFi only..
I can confirm, I've installed update yesterday. The only problem is the lack of space on the device (I had to uninstall many apps and clear temp files for update to proceed to the end), but this is minor issue, and i knew about this (change to ART). I was really hoping for OTA to at least 5.0, so i'm very happy with my choice right now (other option for me was Dell Venue).
Yeppa! Update completed, Lollipop on board!
First (negative) thing I noticed is an issue that also appears on LG G2 (I updated it 2 days ago): clearing Recent apps requires quite a second.. I can clearly see the round progress bar in that second.. Don't know why but I hope they'll fix..
A question to who is still on KK: how much physical space does System Data take? You can see it from Settings / Storage / Misc. Lollipop takes 4.20 GB, but I don't remember how much did KitKat..
Thanks guys..

why not? I did, and it was one of the reason why I bought it! LG always said that the entire G Pad tablet line would have received Lollipop, and they keep their promise!
Funny for me was that usually I always read OTA / firmware update online and then receive it or manually flash (just like for example Nexus 7, LG G2, OnePlus One, all the Samsung Galaxy line etc): this is maybe the first time (except the Froyo/Gingerbread days) the OTA notif really surprised me!! Funny!

I bought it on sale and I watched good reviews, so I didn't buy it expecting an update.
Also, since day 1 it felt like a second line: there was the Pad 8.3 and 10.1, which were "famous", and then this 7.0 popped up with no publicity at all. Not really available almost anywhere (Spain), not many news or forums about it, so I didn't expect to have an update for a non-famous product.
And finally, it works soooooo good I didn't need an update. But of course, I can't resist an update, even less if it's Lollipop (the reason I bought my Nexus 5).
I check once a month anyway, and I googled V400 lollipop an hour ago just "for fun" and I saw this thread, and I was like :cyclops:
Anyway I'm really glad LG kept supporting it! :laugh:

Hey. Just download LG PC Suite (used Windows) and click Check Updates on the pc suite with the tablet connected. The Suite will show you the update after a few minutes and will update via usb.
It's updating apps on bootup now, but it's lollipop and doesn't seem to have wiped (based on the number of apps being updated).
Good luck

just like me, same history.. except that on November (or maybe October??) I read news about LG explaining which phones and tablet would have been update.. the G Pad 7 was there!!
I have to admit that I never loved LG beforethe last 2 years: then I bought the G2 and I started to reconsider the thing.. the G2 is a superb device! Then LG released G3 G Flex 2, G Pad 8.3 and a few entry level phones.. What I still like is the fact that all the LG smartphones look totally different from the competitors ones, even the Bello, Joy entry entry entry entry level devices! And that narrowed bezel on the G2? Amazing!!
And so, this is the story about I started to lie LG!
And when two months ago we decided to buy a new tablet choices were he Asus MeMoPad, Asus FonePad, Samsung Galaxy Tab 3 Lite and G Pad 7. It was not a real matc, no way! G Pad 7 won!

Since I just use it to read some news in bed and not so much, didn't keep updated on it, as I do with the phone.
But I agree with you. I had the LG Optimus Black and after it didn't love LG. Looked cheap and bad. But these last couple of years they are doing great. These tablets and the G3 generation is just awesome. I fell in love with the G3S (G3 mini) although for update matters I ended up with the Nexus (which is LG lol...)
