Help Dust and flicker

[carracerz14]

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?

A single spec of dust could indicate a manufacturing defect. I'd return it just for that. As for the flicker, many people have reported it. I only see it very rarely on the absolute lowest brightness settings when using wifi. I think it got better over time as well...

Yeah. I'm going to exchange it on Monday. Not that big of a deal, I'll just root the new one and flash the backup I have. I love this freaking think though!
