Difficulty: Very hardTroubleshooting Mobile OS Performance and Application Issues

An IT support technician is troubleshooting a mobile tablet used in a warehouse facility. A custom Android inventory scanning application consistently freezes and closes during heavy barcode scanning shifts when handling offline transaction logs. System diagnostic logs report local out-of-memory errors caused by temporary database file accumulation, even though the device retains 15 GB of available internal storage. The technician has already verified the OS is updated and performed a device restart, which provided only brief temporary relief. Which of the following actions should the technician perform NEXT to resolve the issue using the least invasive troubleshooting method?

  1. Clear the inventory application's cache data through the Android OS application settings.Answer
  2. B
    Perform a complete factory reset of the tablet and re-enroll the device in the Mobile Device Management system.
  3. C
    Issue a remote device wipe from the centralized Mobile Device Management console to restore system partition integrity.
  4. D
    Manually download and install a 64-bit application package (APK) directly to bypass default operating system RAM allocations.

Answer

Clear the inventory application's cache data through the Android OS application settings.
Clearing the application's cache removes temporary files and accumulated database logs causing out-of-memory crashes during batch scanning. This follows the least-invasive troubleshooting methodology after a simple restart fails to permanently fix the issue.

Step-by-Step Solution

1
Analyze the reported symptoms and troubleshooting history.
Identified that the issue is isolated to local application memory/cache build-up during offline batching, and a soft reboot only temporarily cleared transient system memory.
CompTIA troubleshooting methodology dictates applying targeted, least-invasive solutions first before escalating to destructive or OS-level actions.
2
Select the next logical step in the mobile application troubleshooting order.
Clearing the application cache directly targets local temporary database buildup causing out-of-memory errors.
Clearing cache removes accumulated junk files without wiping app data, user credentials, or system configurations.
