When should I use the Gyroscope Calibration feature on my Samsung Galaxy S® III?
If you find 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, open the Notification Panel by swiping your finger from the top of the screen to the bottom, and touch Settings > Display > Gyroscope calibration. Place your device on a level surface and touch Calibrate.
