For 2015, Samsung had four different "flagship" devices. It released the 5.1-inch Galaxy S6 and 5.1-inch Galaxy S6 Edge at the beginning of the year and the 5.7-inch Galaxy Note 5 and 5.7-inch Galaxy S6 Edge+ toward the end of the year. The ET news report lists two different models for early 2016. One goes by the codename "HERO1" and has a flat, 5.2-inch display—we'd guess this is the regular Galaxy S7. The other is listed as "HERO2" and has a 5.5-inch curved display.
If Samsung follows last year's naming conventions, the 5.5-inch curved device would be called the "Galaxy S7 Edge+," but the report calls it the "Galaxy S7 Edge." Is the regular Edge just growing in size?
An earlier report from The Wall Street Journal pegged the Galaxy S7 as mostly looking like the Galaxy S6 but with the addition of a pressure-sensitive display, MicroSD slot, and USB Type C port.
We should hear a lot more about the phone at Mobile World Congress, which starts February 22.
