Samsung doesn’t quite have an OS outside of Tizen, which has been discontinued on most of their devices except their TV’s. On mobile devices, they’ve basically gone Android (Wear OS on watches), but they put their own skin on it called One UI, soon to be up to Version 6. They do have an ecosystem with watches, phones, tablet, and PC’s running Windows. They also have a Samsung Store that is installed along side of the Google Play Store that often hosts duplicates of apps already in the Play Store but also contains Samsung apps and some exclusives that do not appear in the Play Store. The ecosystem emulates Apple’s in many ways, trying to share information between their systems, such as passwords and health data, along with features similar to Continuity and Universal Control that works with Windows. Samsung is trying to be Apple by duplicating many of the features Apple releases in their OS’es.
