If you're looking at the bottom of the case with the screen facing up. The strip going across the bottom of the phone above the charging and headphone ports seems to be more pliable than the rest. Im guessing this is by design and is meant to make it easier for you to access the port. Also to make the home button more "pressable" since if it was rigid like the rest of the case it wouldn't be usable.
But I thought I'd check.
