Samsung has registered a new trademark for the name Galaxy Club, which is probably used for an entry level device, or at best a midrange phone. The device was registered in South Korea and the brand is protected by copyright.
There’s also a theory that Galaxy Club will in fact be a service of sorts, or a new premium membership program, like the recent upgrade program launched in a few countries for the Galaxy S7 and S7 Edge. Samsung’s own services aren’t usually that impressive, since for example Galaxy Apps has been a letdown since day one, with very few appealing titles or apps.
Samsung Knox on the other hand is very appreciated and even BlackBerry paid attention to it at some point. S Health and S Voice have evolved over the past years, but they have too strong rivals to matter. Samsung would be smart to launch a social networking app only for Galaxy device users. Now THAT would be interesting.
