probeSensorRanges
Reports the maximum range of the default accelerometer, gyroscope, magnetometer and light sensors.
Privacy: sensor hardware ranges are model-specific and aid fingerprinting; no permission is required to read the Sensor metadata (as opposed to live readings).
Return
Semicolon-separated label=maxRange string (n/a when a sensor is absent).
Parameters
sm
Sensor manager used to look up default sensors.
