I do not see Samsung abandoning android. Android is too powerful to compete. Even MS can't get off the ground.
The app store alone will be reason enough for people not to want to buy Samsung's Phones. Imagine if they pulled Google Play and used their shitty Galaxy Apps store. That thing is a UI nightmare. Touchwiz is moving in the right direction, the UI/UX of Touchwiz Nougat is pretty solid.
Yup, that is what I was alluding to. Building an OS is one thing. Building an app store to compete with Apple and Google is a completely different animal. Samsung does not have Googles advertisement mammoth to compete with so people would actually have to buy most of the apps. Apps is one of MS's biggest downfalls.
