CompTIA A+ Core 1 (220-1101) — Question 102

A user reports the touch screen on an Android smartphone is not responding to any input. The technician has cleared the cache, restarted the phone, and ensured the phone is fully charged. The issue still persists. Which of the following should the technician replace on the phone to MOST likely resolve the issue?

Answer options

• A. System on a chip
• B. Accelerometer
• C. Digitizer
• D. Gyroscope

Correct answer: C

Explanation

The digitizer is the component responsible for detecting touch inputs on the screen, so replacing it is the most likely solution to resolve the unresponsive touch issue. The system on a chip, accelerometer, and gyroscope do not directly impact touch functionality, making them less relevant to this specific problem.
