Samsung has sent out invitations to its latest Unpacked event, where the company is expected to reveal its flagship phone for the year. The Galaxy Unpacked 2015 event will take place on March 1st at 12:30PM ET (6:30PM CET) ahead of Mobile World Congress in Barcelona — the same day rival HTC is set to announce its own flagship. From the teaser image below, it looks like Samsung could well be applying the curved-screen technology seen in the Galaxy Note Edge (above) to its mainline series of smartphones. Last year's Unpacked event at Mobile World Congress saw Samsung unveil new Gear smartwatches, the Gear Fit band, and the Galaxy S5 smartphone. Sales of the S5 disappointed in 2014, however, and the company's profits are down on last year. When reporting earnings last week, Samsung said that its upcoming products would employ "new materials, innovative design, and differentiated features." It has also emerged that Samsung is likely ditching monolithic chip giant Qualcomm as global processor supplier for its next flagship, following unconfirmed reports that the Snapdragon 810 system-on-a-chip overheated during testing. Whatever Samsung has in store, we'll be there to bring you the news live.
