On August 12, more information about the surface duo and its related accessories was released online. The special mobile phone, originally scheduled for launch in the fourth quarter of this year, is expected to be launched ahead of schedule and could cost as much as $1400. < / P > < p > although it is not yet known what accessories will come with the surface duo, it is certain that the accessories for this phone include a custom protective case, a type-C cable, a charging head and a stylus. This means that the surface duo will support stylus input, and this stylus looks very similar to the surface Pro x one in appearance. I wonder if it can be used universally. < / P > < p > it is worth noting that the surface duo will be pre installed with Android 10 instead of windows 10, but some Microsoft applications may be preset, such as our commonly used office three piece suite, edge browser, Microsoft teams, etc. The machine will be equipped with a high pass snapdragon 855, with a memory combination of up to 6GB + 256gb, and a front-end camera of 11 million pixels. The surface duo comes with two 5.65 inch screens, and Microsoft is expected to launch some custom features for this feature.
