Your VIO app is updated using the Google Play™ Store or the Apple App Store. The update is installed automatically in the background or manually by you, depending on the settings on your phone.
If the app update includes an update for the VIO device then the update is automatically installed on the device when the device is connected to the app. Make sure that your phone and VIO device have more than 10% battery charge or that they are connected to a charger. Keep the device connected to the app while the update is installing. When the update is installed, the device restarts.
If the update doesn't install, the message Installation failed is shown on the VIO device.
