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 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.
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.
An unresponsive touch screen is always a hardware failure of the digitizer, so software troubleshooting beyond a restart is unnecessary.
On most modern smartphones, the digitizer (which registers touch input) is laminated together with the display (LCD or OLED) and the outer glass into a single, fused assembly. Therefore, if the digitizer has a hardware failure, the entire screen assembly must typically be replaced. However, before proceeding with a hardware replacement, it is crucial to eliminate potential software causes. Unresponsiveness can be caused by software glitches, corrupted data, or application conflicts. Performing a factory reset (after ensuring data is backed up) is a critical software troubleshooting step to rule out these issues before committing to an expensive hardware repair.
