The biggest novelty in the Samsung Galaxy Watch4 is to be a new system

Portal PhoneArena recalls that the most revolutionary innovation of the Galaxy Watch4 and Galaxy Watch Active4 smart watches should be a change in the operating system. In recent years, Samsung has used its own Tizen OS system. He also uses it, for example, in his smart TVs. Despite being a stable and optimized system, it still has little support for third-party applications.

For this reason, it should be replaced in the new generation of watches by a system on which Samsung is cooperating with Google. Both companies officially announced this a few weeks ago, but did not specify this system. Most likely, it will be WearOS, which will be adapted to the Galaxy Watch directly by Google itself. Samsung has used Google’s watch system in the past. It was the predecessor of the current system, which was originally called Android Wear.
