Arm Wheel test

1. Hold the phone the way you read it, screen facing your face.
2. Stretch your arm straight out in front of you.
3. Press and hold the pad at the bottom with your thumb.
4. Draw a big circle in the air, like turning a giant ship's wheel. The screen keeps facing you, so the phone spins like a clock hand. Seated or lying down: just the top half, a rainbow from side to side.
5. Let go to spin the wheel.

Turn off Silent Mode to hear the clack. Lock the screen to portrait.
