Nexus 7 Screen flicker issues

My nexus 7 screen flickers in low light conditions. I have noticed this primarily when browsing the web in Chrome. Some have suggested that this has to do with a defective auto light sensor and or a weak wifi signal.

The flickering on my Nexus 7 is minor compared to some others I have seen reported on the web. I am debating whether to return mine to the reseller for a replacement. My only concern is that I might get another defective unit as I am unsure whether Asus has remedied the problem. Is anyone else experiencing screen flicker issues with the Nexus 7?
