Question
A user reports that their smartphone’s touchscreen is unresponsive in certain areas. The device has no visible damage, and a soft reset did not resolve the issue. What should the technician do next?
A. Replace the touchscreen digitizer
B. Update the device’s firmware
C. Perform a factory reset
D. Calibrate the touchscreen
E. Check for software conflicts
Answer
E. Check for software conflicts
Explanation
An unresponsive touchscreen in specific areas could be caused by software issues, such as a misbehaving app or corrupted system files. Checking for software conflicts (e.g., by booting into safe mode) is a logical next step before escalating to hardware replacement or invasive troubleshooting.
When a smartphone’s touchscreen is unresponsive in certain areas, with no visible damage and a soft reset has not resolved the issue, the next recommended step is to check for software conflicts. Software issues, such as problematic third-party apps or corrupted system files, are common causes of partial touchscreen failure. Booting the device into safe mode disables third-party apps, allowing the technician to determine if an app is causing the problem. If the touchscreen works in safe mode, uninstalling recently added or suspicious apps can resolve the issue.
Other options such as replacing the touchscreen digitizer or performing a factory reset are more invasive and should only be considered after ruling out software causes. Updating firmware or calibrating the touchscreen may help in rare cases, but identifying and addressing software conflicts is the most logical and non-destructive next step according to industry best practices and CompTIA A+ troubleshooting methodology.
