Samsung Teases 'What's Next' for Galaxy

Could a curvy phone be coming soon?

— -- Samsung has a big secret under wraps that the company plans to unveil next month at the start of the Mobile World Congress in Barcelona.

Invitations for the March 1 event were sent to the media the "Samsung Galaxy Unpacked" event on March 1 -- with the promise of showing off "what's next."

The electronics company hasn't revealed what is on the agenda, however the invitation included a shadowy profile shot of what appeared to be a curvy device, sparking the possibility that Samsung could unveil its Galaxy S6 smartphone with a design change.

Last year, Samsung unveiled its Galaxy S5 at the Mobile World Congress, so it's highly probable the company could use one of the biggest events in the mobile industry to show off its latest flagship device.
