The QR code scanning feature is supported only on Android 15/Android 12 (Region A).
You can first use the browser on your real mobile device to open: https://my.duoplus.net, and log into your DuoPlus account. After opening the cloud mobile, allow the browser to access your camera device, and the cloud mobile can directly call the camera of your real mobile device to scan the code.
If you do not have a device with a camera to open the cloud mobile, we can also scan by uploading a picture of the QR code.
