Samsung is reportedly working on a brand new smartwatch that should succeed the Gear S3 series (launched in late 2016) and the Gear Sport (released in October 2017). According to SamMobile, the new watch has the model number SM-R800, and might be called Samsung Gear S4. For now, though, this name can’t be confirmed.
At the moment, there aren’t many details about this alleged Samsung Gear S4. However, it’s said that the watch should – unsurprisingly – bring upgraded internals, as well as enhanced fitness capabilities, including more accurate sleep tracking.
