Troubleshooting Android-based Smartphone Application Issues

EF.

The situation described is that a customer is experiencing issues with an Android-based smartphone after a recent application update. The application becomes unresponsive immediately after attempting to open it, and auto-sync is not enabled, and no recent backups exist for the smartphone. To further troubleshoot the issue without losing any critical information, the next steps should be:

1. Reboot into Safe Mode: Rebooting the device into Safe Mode is the first step to troubleshoot the issue. Safe Mode is a diagnostic mode that disables all third-party applications and only allows the device to run the core operating system and installed applications. By doing this, it will help to identify whether the issue is caused by a third-party application or the core operating system itself.

2. Clear the application cache: Clearing the application cache can be the next step. It removes any temporary files that the application has stored on the device, which may have become corrupted during the update process. Clearing the cache may help to resolve the issue with the application becoming unresponsive immediately after attempting to open it.

Therefore, the correct answers are A. Reboot into safe mode and F. Clear the application cache.

It is not necessary to contact the application developer or reinstall the application at this point because the issue could be caused by other factors, and these options should be considered only if the first two steps fail to resolve the issue. Doing a force stop or clearing the application data may cause the loss of critical information, so they should be avoided if possible.
