A mobile service technician is troubleshooting a company-issued smartphone used by a field driver. The driver reports that the primary logistics navigation app frequently experiences severe lag and responsiveness delays during use, though it does not crash. Following standard least-invasive troubleshooting procedures, which TWO of the following actions should the technician perform first to resolve the application performance issue?
- Force stop the logistics application using the OS application manager.Answer
- Clear the application cache in the device settings menu.Answer
- CPerform a Clear Data action on the application from the application manager.
- DPerform a factory reset on the mobile smartphone.
Answer
The technician should force stop the logistics application and clear the application cache.
Force stopping the application and clearing its temporary cache are the initial least-invasive troubleshooting steps for isolated mobile app performance issues. Force stopping clears active RAM and halts misbehaving application threads, while clearing the cache removes temporary cached data files that may be corrupted or bloated, all while preserving user settings and login data.
