Samsung Galaxy Watch 4 could feature Wear OS after all Matthew Yap - Apr 01, 2021 Since February, it has been suggested that Samsung would switch out Tizen for Google's Wear OS. There have been multiplerumours in that regard, so the evidence is certainly piling up. In fact, we've just got more hints that this is the case. According to Max Weinbach, the latest version of the Samsung Wearable app contained codes referencing a new plugin called "Water". He claims that this plugin could be a WearOS compatibility layer for the Galaxy Watch 4 and Watch Active 4. The terms 'Merlot' and 'newos' were also included, with the second one possibly meaning "new OS".
