Microsoft previously announced the Surface Duo and Surface Duo 2, dual-screen devices for Android, and developers and enthusiasts can download the source code for the devices from GitHub. Accessing this information makes it easier to create projects such as a Windows 11 port for the first Surface Duo. In addition, it helps to discover anecdotal information about these devices.
According to developer Gustave Monce, the Surface Duo 2 kernel source code hints at a Wi-Fi-only version of the Surface Duo 2 dual-screen device that Microsoft had considered at some point. But Microsoft has never acknowledged the existence of a non-cellular Surface Duo 2 device.
Perhaps the logic behind the idea is to create a cheaper Surface Duo as a companion device to a user’s smartphone — like a scaled-down Surface Neo with Android, rather than a Windows 10X system.
However, in the end, Microsoft abandoned the Wi-Fi-only version and launched the Surface Duo 2 with a cellular network + Wi-Fi version that conforms to the mobile phone form. This device is currently priced at $999 (about 6,903.09 yuan), which has been discounted by $500 (about 3,455 yuan).
