I found switching the screen brightness setting from (A) auto to a set level and this fixed what appeared to be a flicker or constant changing of the brightness level. I was assuming it was software related, however my issue might be unrelated to yours.

I will give that a try, thanks!

I had that too. To fix the flickering, I found installing https://play.google.com/store/apps/details?id=com.nnevod.log... and setting up my own (slightly brighter) curve made the problem go away. It seems the default auto algorithm doesn't sample the ambient light levels over a sufficiently long time period, resulting in too many small changes in brightness.

That sounds like an issue with Asus build quality. They offer customer support. Have you contacted them?

In the printed warranty that came in the box of my Nexus it directs you to support.asus.com

They offer a 12 month warranty.

My warranty directly points you to support.google.com/nexus although in the small print it does mention support.asus.com

But if Google is going to brand a device, design a device, market a device, and sell the device, they should do a better job supporting the device.
