Although they have never really disappeared, traditional smartphone manufacturers have more or less backed out of the smartwatch market. It has become the territory of accessory makers and luxury brands like Fossil or TAG Heuer. One OEM (aside from Apple) that has remained consistent is Samsung with its Gear line of smartwatches and fitness trackers. But while a new smartwatch is still expected to debut in a few months, change is reportedly afoot. Samsung might be switching back to Wear OS, formerly Android Wear, and it might actually start with this year's Gear S4.
