In order to transfer files from the LX1 Smart Glasses via USB, you will first need to change the USB mode in Settings.
This can be accessed in Settings > Connected Devices > USB to bring up the menu. From there, select the “File Transfer“ option.
Once enabled, you will be able to navigate the file system on the LX1 Smart Glasses when plugged into a computer via USB.
It will appear as a standard USB storage device.
Please note that the 'Transfer files' mode will remain enabled only during the current USB session. If you disconnect the LX1 Smart Glasses from your PC or reboot the device, you will need to re-enable this mode.
This is by design and is standard Android behavior for security reasons.
