Tizen, not Android, to run Samsung's next Gear smartwatch. 

        Samsung on Monday will unveil its second-generation Galaxy Gear smartwatch, this one running the open source Tizen operating system, not the Android software that runs the first-generation model, according to reportsSamsung is by far the largest maker of Android smartphones and its relationship with Google is complex. Recently the two companies signed a 10-year cross-licensing deal on patents, while Google also sold Motorola to Lenovo. The latter move allayed Samsung concerns that Motorola could get preferentially treatment for Android innovations.
