- Durability: The flash drive is designed with resistance to high temperatures, water, dust, drops, and magnetic interference. However, avoid exposing it to extreme conditions to ensure longevity.

6. Troubleshooting
- Drive Not Recognized (iPhone/iPad): If the flash drive is not recognized by your iPhone or iPad, try uninstalling the "LuxSync PRO" app, restarting your phone, and then manually re-downloading the app from the App Store. Ensure you grant all necessary permissions upon reconnection.
- Drive Not Recognized (Android): Verify that the OTG function is enabled in your Android phone's settings. Some devices require this to be manually turned on.
- Cannot Transfer Certain Files: Media files downloaded from platforms like iTunes or other third-party applications may be protected by Digital Rights Management (DRM) and cannot be transferred or viewed directly from the flash drive.
- Transfer Issues/Errors: If you encounter difficulties transferring files, consider checking the format of the flash drive. For large capacities, exFAT is generally more stable. You may need to reformat the drive (after backing up all data) to exFAT if it is currently FAT32.
- App Issues: If the "LuxSync PRO" app behaves unexpectedly, try force-closing it and reopening. If the problem persists, reinstalling the app as described above may resolve it.
