The most recent numbers I've heard of is 75%. So android is typically a battle to the bottom, with various mostly failed efforts, consolidation, various vendors giving up on markets, etc. Motorola (bought and then sold by google), Sony, HTC and many others are not making much profit. Samsung is doing better, but constantly fighting cheaper competitors. Seems like Samsung is doing as well as it is, because of synergies relating to their production of CPUs, having a chip fab, screens, dram, flash, and cameras for the world wide market.
Android's a tough market to be in, you are competing with Google (who makes pixel phones), numerous low cost manufacturers, Apple, and your ecosystem taxed by google through the app store and the market is split among many companies in the android system so it's hard to catch google's services, play store, etc. Not that android manufacturers aren't trying. Amazon made an effort, but seems to have largely given up on calling their devices android.
I wonder if driverless cars could follow that same android lath with Waymo being the alternative car OS that all the other companies have to use - but this time having to also pay google a lot more!
