I have a 32gb 2nd gen and a New 3rd gen 64gb and the 32gb 2nd gen sound's clear at max speaker volume and the 64gb sounds very distorted on the max volume is that normal??? plus the 64gb has a blue hue to the screen compared to the 32gb is that just how the new screens look? anyone have any insight cause im hoping i just got a crappy one that i can get replaced or fixed. THANKS
