Vilo periodically makes updates to the firmware to enhance user experience and fix possible bugs.
When a firmware update is available a pop-up will appear when you open the Vilo app. If for some reason a pop-up does not appear prompting you to update there are two ways you can manually update the firmware.
Open the "System Dashboard"
Tap on "Firmware"
If there is an update it will appear here and prompt you to update
Tap "Firmware Upgrade"
If there is an update it will appear here and prompt you to update.
