Update:
Just got back from the Verizon store and had it exchanged so everything is good now, but I may have found out what that blue dot was. The Verizon rep said it's common when you put too much pressure on the screen, that it permanently distort that area. I told her that I never have used that much pressure. Upon further inspection of the phone, we also noticed a piece of lint stuck in between the glass so that was enough of a reason to exchange for a brand new one.
After leaving the store happy, I realized that I may have put pressure on the screen when taking the phone out from my holster. I bought the Verizon brand case and holster combo and I just think it's poorly designed as its a tight fit and the phone is so long. But anyway, it's not like I used all my strength to take it out. I've treated my incredible worse I would think. Was it just that one DNA that had a week display or are these phones that fragile now?
