Which of the following is responsible for flipping the image when a smartphone is rotated?
The correct answer is C. Gyroscope. A gyroscope measures the rate of rotation and angular velocity of the device, allowing the operating system to precisely detect orientation changes - such as rotating from portrait to landscape - and respond by flipping the display. While the accelerometer measures linear…

Explanation
A gyroscope measures the rate of rotation and angular velocity of the device, allowing the operating system to precisely detect orientation changes - such as rotating from portrait to landscape - and respond by flipping the display. While the accelerometer measures linear acceleration and gravitational force (and can estimate orientation), the gyroscope provides more accurate and responsive rotational data used for screen rotation. A shock sensor detects sudden impacts to protect components like the hard drive. An ambient light sensor measures surrounding light levels to automatically adjust screen brightness.
