title: Android- Gyro Sensor
body: <p>I am using LG Optimus 2x smartphone which consists of  gyro and accelrometer sensors. I am using it in indoor tracking application by using pedestrian dead reckoning techniques. I want to use gyro sensor to get correct orientation of mobile. I am integrating gyro data over time to get angles. But these angles are not well accurate. how I  can get error free angles from Gyro sensor. </p>
