Where are downloaded media files stored on Android?

When downloading media files from your Blueye underwater drone to your Android device, the files are stored in a Blueye subfolder in the DCIM directory. The exact location depends on your device, but the path would typically be:  Internal Storage/DCIM/Blueye/file_name.mp4.

You can find the files using the system File Browser app. Most Android devices will scan the DCIM folder for media files and display them in the system Gallery app.
