measure azimuth pitch or roll directly. We call those Euler angles BTW . Instead it uses accelerometers and magnetometers.. the device is tilted up at 90° or near it then the use of Euler angles falls apart. This is a degenerate case mathematically... doing it wrong. The only time you actually want the Euler angles is to display orientation information in a user friendly..

device doesn't contain compass or inclinometers so it doesn't measure azimuth pitch or roll directly. We call those Euler angles BTW . Instead it uses accelerometers and magnetometers both of which produce 3 space XYZ vectors. These are used.. that the function lets you manipulate the matrix first. If the device is tilted up at 90° or near it then the use of Euler angles falls apart. This is a degenerate case mathematically. In this realm how is the device supposed to know if you're.. the TYPE_ORIENTATION sensor or from getOrientation you're probably doing it wrong. The only time you actually want the Euler angles is to display orientation information in a user friendly form to annotate a photograph to drive flight instrument..

This is a common problem with yaw pitch and roll. You cannot get rid of it as long as you are using yaw pitch and roll Euler angles . This video explains why see at 38 25.

relative to North matter I guess not. It is far easier to compare the acceleration vectors than orientations Euler angles rotation matrices quaternions as tc pointed that out. If you are using acceleration data you have 3 dimensional vectors..
