It's all about execution. When Android manufacturers make these "innovations," by and large they're sloppily implemented and poorly communicated. They're generally part of dozens of features that companies like Samsung try to boast about - so the net result is that consumers don't know what to pay attention to, they aren't inspired to feel lust for the product or any of its particular features, and so the product becomes just one more indistinct phone on the scrapheap.

Whereas Apple focuses on a few core features to improve on and communicate with each phone, and they're overwhelmingly cautious - like only integrating Touch ID with a few spots of the phone at first. But they nail the initial execution, and the communication. So their phones are still the absolute centre of the market. And no other company can inspire product lust to the degree they can.
