Samsung makes really great hardware (speaking in terms of the computing functionality of the machine, not industrial design where I think they are merely average at best), but I've never used Samsung software that didn't make me want to smash something. It is always possible they might someday turn that around, but as of right now their best bet is to stick with the Android ecosystem and let Google do most of the software work.
It was the same feeling with Android until not so long ago. If Google can work to incrementally improve the user experience, I'm sure Samsung could. If they have the incentive. But maybe they are fine with the current state of affairs.
