Just got my nexus 7 3 days ago and today I noticed that there is a spec of dust under the screen, it's nothing bad it's literally just one piece of dust, but I noticed it and now I can't stop looking at it. I'm very ocd about stuff like that.

Also sometimes I will notice the back light flicker. It was doing it real bad the other day and narrowed it now to my very poor wifi signal. It stopped doing it after I connected to better wifi, but today I noticed it was doing it a little bit on dim screens.

In need input. I bought it from Walmart, I have like 12 days left to return and exchange it. Don you guys think I should just go ahead and exchange it?
