I think teh Sensor API is not correctly installed in your phone.

Or the installer.sis does not connecting (directing) to the sensor API.

Use the latest version of Qt mobility, 1.0.2 or newer ...

Best regards,

the folder is 1.0.2 but how do i know whether the sensor.sis is connecting to the Sensor Api?
