It appears that Samsung has registered a bunch of new product names, but we don't know if they'll ever be used. Some of these names include the Galaxy S Kit, Galaxy S Mate, Galaxy S Impact, and Galaxy S Act. These have all been spotted in a Samsung trademark filing in the US. Which means if these devices ever do become a reality, they will be headed to the US eventually.
So far we haven't seen any leaks or any rumors of these devices, so more than likely they aren't coming soon, if they come at all. Samsung first half of 2013's roadmap was even leaked, and showed a ton of devices. But none with these names. So these could be devices coming out in 2014 or later, and chances are a few of them will be scrapped.
Now in addition to all these Galaxy S models, Samsung is also looking to register the ATIV Zexy trademark in Europe. The ATIV name has been used on their Windows Phone 8 devices, so we are almost certain that would be a Windows Phone device coming soon. Again if the device actually ever does become a reality. So we aren't going to worry about the ATIV Zexy, even though it's a catchy name. But once we get more information on the Galaxy S devices listed above, we'll be sure to bring them to you.
Like I said above, I highly doubt we'll see these devices at Mobile World Congress later this month. But the Galaxy S Mate sounds like one of those massive devices like the Huawei Ascend Mate. So perhaps Samsung is looking to do a 6-inch or bigger device soon? The others, I'm not to sure what they could be based on the name. Although I'd love to say "I have the Galaxy S Impact" when people ask what phone I have. It just sounds cool.
So five new Android devices and a Windows Phone. I wonder which OS is doing better for Samsung?
