The first question should be, Is it possible to convert Your Phone into Android Phone? The staright answer is No. There is no posibility to install Android Operating system inside Samsung Z Phones.
This is the rising time os Samsung's Android Operating system and it is trying to compete iOS. There is no chance to complete theses two mobile operating systems, but in case, Samsung is supporting this OS with it's Z series phones. And as Samsung is largest Moible Selling Brand for past few months, there is a chance that Samsung push its own OS in market. The required parameter to set place in market is the number of Applications available in Store. As much users get variation of applications, chances of stability is also increase in this race.
Another positive point from android side is it's broad usage. Android is not only build for phone, but samsung useing this OS in it's own TV production and Gear Series smartwatches too. And now a days Samsung Gear is at top in Smart Watch Selling. Day by day, Mobile Application developers are also increse in Software Developement market and Samsung is also promoting its OS by Incentive Program.
