CompTIA A+ 220-1101 (V14) Practice Question

A technician is troubleshooting a smartphone with an unresponsive touch screen. After restarting the phone, the issue persists. Which of the following statements MOST accurately describes the nature of this component and the next troubleshooting steps?

  • The digitizer is typically integrated into the main display assembly. Before replacing the assembly, the technician should perform further software troubleshooting, such as a factory reset.

  • The digitizer is a separate component from the LCD, allowing for its individual replacement. The next step is to open the device and replace the digitizer.

  • The problem is likely with the wireless antenna's connection to the digitizer, and the technician should check the antenna's routing around the display.

  • An unresponsive touch screen is always a hardware failure of the digitizer, so software troubleshooting beyond a restart is unnecessary.
