Apple Seeds Second Beta of iOS 10.3.2 to Developers

You can't compare that way. A lot of the phone is not tied into the base OS but updated far more regularly as part of Google Play Services. For example, Google can update Maps by pushing a new version of Play Services without having to update the whole OS and usually without the end user noticing. Browser components are also in there as well as anything non-open source. This is far more efficient and responsive than Apple's monolithic updates, where we wait a whole year to get some simple feature added in Books or Maps.

You forget that there are already more android users around with the latest version available than there are iOS users. Google is hard working to solve the fragmentation issues on Android and over the air updates. Once they've solved that issue, there is even less reason to buy iPhone. Somehow the evolution seems to go so much faster on Android than on iOS. I really hope Apple will turn the table but it has proven not to for at least four years.

Update: Google's Android Nougat update is being used on 5% of active devices as of April, and the five-month-old software is in the offing for other handsets. Here's the latest list.
