Is Samsung ditching Tizen for Wear OS?
The Samsung Galaxy Gear and Gear Live were the last Android Wear-powered smartwatches Samsung released before shifting to its own Tizen operating system. That might change soon, though. According to Evan Blass (a.k.a. @evleaks), Samsung employees have been spotted wearing Gear watches that were Wear OS-powered instead of Tizen-powered.
It has been rumoured that Samsung was planning to rebrand its Gear smartwatches. The company has even applied for trademarks on the names Galaxy Watch and Galaxy Fit. But with these new rumors, it looks like they might even be thinking of dropping its own operating system in favor of the rebranded Wear OS platform. Samsung hasn't released a smartphone in a while, so it should be interesting to see what they plan to do with this.
