It seems the days of interchangeable OS has really arrived, with the recently announced Yezz Billy 5s being another example of a handset that runs both Android and Windows Phone on identical hardware.
As can be seen in the video above, the very thin device has no markings distinguishing the OS, using on-screen navigation buttons, making it easy to sell the device with either OS pre-installed.
Yezz says they hope to eventually sell the device with Windows 10 also.
The handset will be on sale for less than $300 in either version. Read more about the specs here.
