In order to transfer files from the Vuzix M400 and M4000 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 mode for "Transfer files".

Once enabled, you will be able to navigate the file system on the Vuzix M400 and M4000 Smart Glasses when plugged into a computer via USB. It will appear as a standard USB storage device.

Please note that 'Transfer files' mode will remain enabled only during the current USB session. If you disconnect the Vuzix M400 and M4000 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.

No, the M-Series Smart Glasses do not support the Play Store or other Google Mobile Services (GMS) not covered by the Android Open Source license.

Vuzix hosts an alternative App Store that supports content developed specifically for the M-Series Smart Glasses.

Yes, the M-Series Smart Glasses Speech Recognition engine includes a set of basic navigation and control commands by default. These commands are globally accessible on the M-Series Smart Glasses while the recognizer is enabled.

To enable, go to the Speech Recognition menu located under Settings > System > Languages & input, and toggle the “Vuzix Speech Recognition” option. From this screen, you can also modify the sensitivity and timeout settings of the Speech Recognition engine. Sensitivity will adjust the amount of accuracy required by the recognizer when listening for a phrase, and timeout will adjust how long the recognizer will continue listening for commands after the keyword or the last voice command is issued. By default, the timeout is 15 seconds. Setting the timeout slider to the maximum value will set the timeout to an unlimited value, though it is important to keep in mind this will increase battery usage by the recognizer.

To issue voice commands, you must first speak the “Hello Vuzix” keyword to trigger the listener which will remain active for the timeout duration. Issuing additional commands will reset this timeout.

To see a full list of commands, navigate to Settings > System > Languages & input > Speech Recognition > Speech Commands List, or if speech recognition is enabled, say "Hello Vuzix, Speech commands."
