When we talk about the mobile device market, you probably won't think of Microsoft at all in the first time.
We usually think of many Android and Apple phones.
Since I was collecting data from Microsoft recently, I recorded the development history of Microsoft's mobile device.
market share
This year (2019-2020), Windows Phone stopped supporting and the kernel of the new mobile device was changed to Android kernel, not to mention the current low market share.
I think that the current use of Android to launch new products of their own brand, and at most optimize the linkage service of their own Windows operating system, this is a cost-effective way, and there is no need to invest resources in developing their own mobile operating system.
It can be seen from the market share of 0.15% that, in any case, there are still a small number of diehard fans buying its products.
0.15% doesn't sound like much, but if there are 10,000 people today, 15 people will buy it. If one billion people had a mobile phone today, 1.5 million would buy it!
