The much awaited Samsung flagship smartphone of the year -- Galaxy S7 -- is expected to come in three variants, not two as previously reported.

Popular Twitter spy Evan Blass (@evleaks) has posted a portion of a promotional poster of Samsung Galaxy S7 series revealing that the company will unveil three models -- one a standard Galaxy S7, another S7 Edge and a phablet model S7 Edge+.

Though there is no proof to validate the authenticity of the poster, the impressive track record of evleaks makes us believe that this image might be the real deal.

Previously, reports had indicated Samsung might unveil flat panel-based regular 5.1-inch Galaxy S7 and a big 5.7-inch based S7 Edge, but earlier this week, a Galaxy S7 Edge device with 5.1-inch QHD display appeared on AnTuTu performance benchmarking site. This apparently led to confusion in the media. Many believed that phablet-based Samsung Galaxy S7 might have been a prototype and the company could have axed it and gone ahead with 5.1-inch screen.

Thanks to Evan Blass' leaked Galaxy S7 series poster, we are starting to get a clearer picture. In 2015, Samsung unveiled Galaxy S6 and S6 Edge with the same 5.1-inch screen and later, the company launched 5.7-inch based Galaxy S6 Edge+ along with Note 5.

This year, it looks like Samsung will pull the wraps off on all three Galaxy S7 models at a single event.

Samsung's Galaxy S7 series is expected to be unveiled on 21 February, just a day ahead of the internationally acclaimed consumer electronics trade fair MWC (Mobile World Congress) 2016, Barcelona (22-25 February).

Expected features of Samsung Galaxy S7 series:

The upcoming Samsung flagships are expected to come packed with 4GB RAM, 64GB inbuilt memory, 12MP camera with f/1.7 aperture and 5MP wide-angle front snapper.

All the devices are said to come in two SoC (System on Chip) variants depending on the region of sale. One will house the company's proprietary Exynos 8890 series Octa-core CPU and the other with Qualcomm's 2.2GHz Snapdragon 820 series quad-core processor.
