CompTIA A+ Core 1 (220-1101) — Question 23

A user reports issues with a smartphone after dropping it. The icons on the screen all look normal, but when the user touches the email icon, for example, nothing happens. Which of the following is MOST likely the cause?

Answer options

• A. Digitizer issues
• B. Overheating
• C. Broken screen
• D. Malware

Correct answer: A

Explanation

The most likely cause of the problem is digitizer issues, as the digitizer is responsible for registering touch input on the screen. Even if the screen appears visually intact, damage to the digitizer can result in unresponsive touch areas. Other options such as overheating, a broken screen, or malware do not specifically explain the lack of touch response in this scenario.
