It remains to be seen whether this is the final design of the Nokia C1, so take this with a huge pinch of salt, especially since the tipster who picked up this render is far from having a reliable track record for the simple fact that it is a first time leak. The interesting point about this leak would be the idea that the alleged Nokia C1 render depicts Android running in the foreground in addition to Windows 10 Mobile.
Does this mean that we will see two versions of the smartphone when it is released, with each variant running the respective mobile operating system? Only time will be able to tell, but to date all rumors have always pointed to the Android platform, so to see Windows 10 Mobile arrive would be a real pleasant surprise.
