A. 1. Check App Settings: Some apps allow data to be moved to an SD card. Go to Settings > Apps > [App Name] > Storage and see if the "Change" option is available. 2. Use File Manager: Use a file manager app to manually move files to the SD card, if the app data itself cannot be moved.

B. 3. Format SD Card: Ensure the SD card is formatted correctly (usually exFAT or FAT32) to be compatible with your device.
