On a BlackBerry® device with an accelerometer, you can create a BlackBerry device application that listens for accelerometer events and retrieves data about the orientation of the BlackBerry device.

The BlackBerry OS converts accelerometer readings into orientation coordinates such as TOP_UP, FACE_UP, and LEFT_UP. The BlackBerry OS may also rotate the screen in response to accelerometer readings.

Querying the accelerometer consumes battery power. Connections to the accelerometer should not be kept open for long periods of time.
