CompTIA A+ Core 1 (220-1101) — Question 204

A technician is troubleshooting a smartphone that has a large dark area on the screen. The screen has no damage to indicate that it is cracked. Which of the following BEST describes why a blot is on the screen?

Answer options

• A. Digitizer damage
• B. Improper charging
• C. Ambient light sensor damage
• D. Liquid damage

Correct answer: D

Explanation

Liquid damage is the most likely cause of a large dark area on the screen, as it can affect the display's functionality without leaving external signs of damage. The other options, such as digitizer damage and improper charging, typically present differently and would not solely result in a blot on the screen.
