Yea, when I read your original post, I thought for sure that you'd be able to turn it on in settings, but after looking I realized it didn't exist. Something they should really consider adding in a future firmware update.

Edit: If you're going to make a warranty claim anyway, I'd try a factory reset. You never know, it may be a problem on the software side, not recognizing the button press. Unlikely, but worth a shot.
