Previously, Microsoft was still busy with its own smartphone operating system Windows Phone, but that was not the success that the IT company was hoping for. So now it has switched to Android and the Surface Duo is the first Microsoft smartphone with this operating system. Smartphone is not quite the right word, however, because this is a dual-screen phone that, with the screens against each other, can simply be called a tablet.
The phone has two 5.6-inch screens with a resolution of 1800×1350. The OLED panels are brought together thanks to a hinge that can move 360 degrees. The refresh rate is a bit on the low side at 60Hz. The phone doesn’t have an overly large battery either: with only 3577mAh for two screens, you probably won’t get through a day with it. An advantage is that Surface Duo is nice and thin: when opened it measures only 4.8mm. We just wonder if that thinness is worth the small battery.
