When should I use the Gyroscope Calibration feature on my Samsung Galaxy S® III?
If you find that your device is not reacting to your motion gestures very well, and you have adjusted the sensitivity of the gestures (when applicable), you may need to calibrate the gyroscope in your device. The gyroscope sensor allows your device to calculate the movement of the device.
To calibrate the gyroscope, from the Home screen, touch Menu > Settings > Motion > Sensitivity settings > Gyroscope calibration. Place your device on a level surface and touch Calibrate when the blue dot is in the center of the target.
