I didn't think I had the screen problem until recently. I dont know if it just turned up or I was just looking for it. Obviously I dont want an defective unit. My question is I (my girlfriend rather) dropped it. There is a very very very small knick on the bottom corner. Probably would'nt notice it unless you examined it. Would it be a problem to return it. This issue obviously doesnt have anything to do with being dropped so they could'nt argue that (if they even noticed it) What do you all think?
