I’m using Samsung Galaxy S3. When I retrieved the available sensors:

I got a result like below:

 LSM330DLC 3-axis Accelerometer                    TYPE_ACCELEROMETER        
 AK8975C 3-axis Magnetic field sensor              TYPE_MAGNETIC_FIELD

 Gravity Sensor - software sensor                  TYPE_GRAVITY              
 Linear Acceleration Sensor                        TYPE_LINEAR_ACCELERATION   
 Orientation Sensor                                TYPE_ORIENTATION           
 Corrected Gyroscope Sensor                        TYPE_GYROSCOPE

STMicroelectronics seems to be the default one and sensors provided by Google Inc and Samsung Inc may be the secondary sensors.
When I used getVendor() method, it returned STMicroelectronics(being the hardware default sensor) and Samsung. But when I registered both of the sensors, the onSensorChanged() was called that returned the orientation values(pitch, roll and azimuth) with great difference.

Example, I got the following values at the same timestamp(with difference of few seconds). 

                         pitch:       roll:                   azimuth:
Samsung                 0.5917465    -4.212                   84.583
STMicroelectronics      0.0865345    -3.88854                 356.825

Any idea of why there is a difference in both or should we always monitor both the hardware and software sensors?

    The 2 sensors are provided by the 2 vendors as mentioned by madhus. It can be obtained using the code:

    List<Sensor> gyro =mSensorManager.getSensorList(Sensor.TYPE_GYROSCOPE); 
for(int i=0;i<gyro.size();i++) { 
Log.d(TAG,"The vendor is: " +gyro.get(i).getVendor() + " **" +gyro.get(i).getVersion());
}

    I got the vendors as STMicroElectronics and google Inc for all the sensors, except orientation(Samsung Inc and STMicroElectronics). However, as the default and hardware sensor is STMicroElectronics, I am using that.
