A user has contacted the IT department stating their company Android device will not rotate it's screen orientation, even when auto-rotate is enabled. Which of the following sensors is likely malfunctioning?
In mobile devices, the Gyroscope is a sensor that uses gravity to detect a devices orientation. The gyroscope provides the mobile operating system with data to determine how the screen should be displayed.
A gyroscope (from Ancient Greek γῦρος gûros, "circle" and σκοπέω skopéō, "to look") is a spinning wheel or disc in which the axis of rotation is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum. Because of this, gyroscopes are useful for measuring or maintaining orientation.
Gyroscopes based on other operating principles also exist, such …
