CompTIA A+ Core 1 (220-1201) — Question 97

A user’s phone does not respond to touch. A technician inspects the phone but does not see any evidence of physical damage. The technician restarts the device, which does not fix the issue. Which of the following components should the technician examine next?

Answer options

• A. Battery
• B. Screen
• C. Stylus
• D. Digitizer

Correct answer: D

Explanation

The digitizer is responsible for detecting touch inputs on the screen, so if the screen appears undamaged but is unresponsive, it is likely that the digitizer is malfunctioning. The battery and screen may also be examined, but they are less likely to be the direct cause of touch input issues when there is no visible damage.
