3Q 2016: Worldwide Smartphone Sales to End Users by Operating System by Gartner.

In the smartphone operating system (OS) market, Google's Android continued to capture market share from Apple's iOS, to command nearly 88 percent of the total market (see Table 2 above).

 "The withdrawal of Samsung's Galaxy Note 7 may benefit sales of Apple's iPhone 7 Plus only slightly, as Note 7 users are likely to stay with Samsung or at least with Android," said Roberta Cozza, research director at Gartner. "To some extent, other Android vendors could capitalize on this situation in the short term — for example, Huawei and other Chinese brands present in the premium Android phone segment. 

The Note 7's withdrawal also comes at a good time for Google in mature markets, where it’s Pixel and Pixel XL devices have started selling."
