How Good is Your Mobile Phone as an Angle Gauge?

First off, remove the snap on case from the phone so the phone chassis is in direct contact with the sine bar.

This concerned me at first, but the case fits tight on the phone and doesn't rock. Therefore, once you calibrate for zero, any effect of the case is removed.

Actually, a case that had a square cross-section that would allow the phone to balance on it's edge would be an advantage in this application.
