You can do this by connecting Vision on your phone App and Wi-Fi. Once you confirm there's a new software available, the update will happen automatically Over-the-Air (OTA).
You may also update it manually by following the Step-by-step Guide.
Ensure the USB stick is formatted in FAT32.
It is important that the Landroid Vision is charging, and the battery capacity has reached 50% prior to starting the firmware update.
Landroid Vision will automatically restart after the update is completed.
