220-802 Question #731: Real Exam Question with Answer & Explanation

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 acceler

Question

Which of the following is responsible for flipping the image when a smartphone is rotated?

Options

AAccelerometer
BShock sensor
CGyroscope
DAmbient light sensor

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.
