It depends on which hand you're holding the phone in and doing it one-handed. Right hand, your fingers are underneath, palm is supporting the right side of the face so it doesn't go anywhere when you push the buttons with the tip of your fingers.

Left hand, unless your fingertips are on the face supporting the right side, you hit the volume button with your thumb and it causes the face to slide. Kind of bad design for lefties like myself, but just have to get accustomed to it, rather than having your fingertips on the body only.
