Brand new iPod touch 6th generation. Touchy home button.

Hi everyone. I recently purchased a new iPod touch 6th generation from macmall which is an authorized apple reseller, so I have a 1 year apple warranty. I noticed right out of the box that the home button only responds well if you press it in the very center, or really hard anywhere else. So if I miss it becomes quite the annoyance. Would this be covered by the apple warranty to fix, or am I going to have to pay for it if i want it fixed?
