As a VZW rep, if I took you're call I would refer you to the store. This would be with your best interest in mind, and not just to avoid having to issue a replacement. My reasoning would be that, I've heard A LOT of people say that this is due to moisture/humidity. If I send out a replacement device, I have no way to guarantee you that the person who checks the phone in at the warehouse, won't end up classifying it as water damage. And if that happens, then you're on the hook for the full retail cost of the device.

Go to a store, and have a tech look at it. If the tech concludes that it is a warranty issue, and not water damage, tell them to notate their conlusion on your account. This will cover your rear in case the above scenario happens. From there, they'll either replace the phone on the spot (if stock is available) or they'll call tech support and have a replacement shipped to you.
