According to a new report, Microsoft has ceased developing a Surface Duo 2 successor. While the design of the Surface Duo 3 had been finalised, Microsoft has now moved away from the dual-screen format of the Surface Duo and Surface Duo 2. Instead, it seems that Microsoft is headed down the Galaxy Z Fold4 and Oppo Find N2 route. A conventional candybar smartphone could be in the offing, too.
