Wouldn't know what to tell you except return it and try some place else. Bestbuy might of gotten a bad shipment or something. Some have reported build quality issue but a lot of others have reported having no issues what so ever look here, http://forum.xda-developers.com/show....php?t=2407866
I as well got mine off amazon, through amazon them selves, no separate sellers and have had very good luck with no issues after testing what others have reported. Can only say keep trying maybe some where else if have to other wise like you said if your too fed up then maybe go with something else. The new Asus memo fhd's are coming out soon but went with the nexus 7 my self because looked like had the best options, also the new nexus 10 should be coming out at some point just don't know when.
