The other trademarked moniker, the Samsung Ativ S will probably be used for a range of high-end Windows Phone 8 smartphones. It's simple really, Samsung Galaxy S represents the Korean manufacturer's high-end Android phones while the Samsung Ativ S does the same for its Windows Phone 8 handsets. Make any sense?
The good thing is that we are just days away from the start of IFA which means we should know the answers to all of your questions really, really soon.
