Samsung pulling back on Tizen?
The drum beats for Tizen were at their loudest when it appeared as though Samsung wanted Google to understand that Samsung's success with devices like the Samsung Galaxy S III and the Samsung GALAXY Note II had a lot to do with the manufacturer itself and not just the Android platform.
While at the time, there was talk about Samsung switching to Tizen for its smartphones, that seems unlikely considering the huge market share that the Google open source OS owns globally. Swapping Android for an unproven platform would not only be likely to knock Samsung down from its leadership among smartphone manufacturers, it would probably breathe some life into other Android handset producers like HTC and Motorola that are trying to recapture attention from the smartphone buying public. Knowing that a Samsung move to Tizen could positively impact its wholly owned Motorola subsidiary is probably one reason why Google has been so calm about the whole affair.
