Samsung appears to be testing a new mystery device that could be its next Tizen-powered smartphone.

The device recently showed up in the Zauba shipping database under the label SM-Z910F. Samsung uses the “SM-Z” prefix for its Tizen Developer devices that are not intended for the mass market.
The SM-Z910F was spotted making rounds at Samsung’s R&D facility in India. Intriguingly, it’s listed in three variants – for Russia, the UK, and France – hinting at a limited release.
Samsung officials have previously suggested in interviews that the company’s next Tizen phone would have restricted availability. Tizen is Samsung’s homegrown operating system, but it has struggled to compete with Android and lacks mainstream app support.
While details on the SM-Z910F are scarce, the model number and shipping information suggest Samsung is actively developing a new Tizen device despite the challenges facing the platform. However, given its limited testing regions, the phone is unlikely to see a wide global launch.
Samsung watchers will be keeping a close eye on the SM-Z910F to see if it materializes as Samsung’s next flagship Tizen phone. But with availability possibly limited, it may be more of an experimental release than a major product launch. Either way, it shows Samsung isn’t throwing in the towel on Tizen just yet.
