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.
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.
[fix] An easy way to solve the screen flicker with just a scotch tape
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?
