hey guys, having a little bit of a trouble with that button.

it's been fine until 5 minutes ago. now, the button has lost that "clicky" feeling and it's a bit of a struggle to press. i'm wondering if this is worth taking it into the store and have it checked out because my warranty is now gone or wait until it breaks for sure(well, can't really do much about it anyway since i'm in a different country until the end of the summer...)
the only case i've had on is the ghost armor for the past year and maybe dropped the phone 1-2 times. i'm guessing the button has worn out?
