Tizen hasn’t exactly risen to challenge Android in any meaningful way, it hasn’t even been able to beat out Windows Phone as the third most-popular mobile operating system, but Samsung is far from finished with it. The successor to the mildly successful Samsung Z1 was recently approved by the FCC, which means there’s a good chance that we could see it in the United States, but it’ll most likely only be a minor market. Instead, Samsung will probably focus more on developing market with the Samsung Z3, as those have been where Tizen-powered devices have been the most successful.
