CompTIA A+ Core 2 (220-1102) — Question 222

A technician is troubleshooting a mobile device that was dropped. The technician finds that the screen fails to rotate, even though the settings are correctly applied. Which of the following pieces of hardware should the technician replace to resolve the issue?

Answer options

• A. LCD
• B. Battery
• C. Accelerometer
• D. Digitizer

Correct answer: C

Explanation

The correct answer is C, the Accelerometer, as it is responsible for detecting the device's orientation and enabling screen rotation. The LCD, Battery, and Digitizer do not influence the screen's ability to rotate, as they serve different functions related to display, power, and touch input, respectively.
