According to Appunwrapper.com: "Door 15: Take the bomb from the bottom left corner of the screen. Place it in front of the door and then light it with the torch. It will explode, leaving some markings on the sides of the door. They’re arrows. Tilt your phone in the direction of each arrow to roll the ball to that side. Pull the handle each time. If there are three arrows on the same side, keep the ball there and pull the handle three times."
