Samsung is paving way for greater success in the premium smartphone market. The company's Galaxy S7 is expected to release early next year, challenging its biggest rivals, including Apple and others. The details of the unannounced flagship have been making the rounds of the internet for quite some time and a new leak brings closure to the device's screen sizes and a look at the renders.

In an exclusive report by GSM Arena, citing a smartphone case manufacturer ITSkins, two variants of Samsung Galaxy S7 are to be released. One of the variants will measure 143.37 x 70.8 x 6.94mm, which translates to a 5.1-inch display just like the Galaxy S6.

On the other hand, the second variant is said to measure 163.32 x 82.01 x 7.82mm, which means it could get a 6-inch display. Comparatively, the Galaxy S6 Edge+ features a 5.7-inch screen and measures 154.4 75.8 x 6.9 mm. The reported screen size for the second variant of the Galaxy S7, most likely S7 Plus, is similar to Galaxy Mega 2, which measures 163.6 x 84.9 x 8.6 mm.

Based on these measurements, ITSkins indicates Samsung will replace the Galaxy S7 Edge variant with Galaxy S7 Plus, reserving the dual-edge screen variant to a later launch alongside Galaxy Note 6.

Based on the leaked renders of the rumoured Galaxy S7, Samsung seems to follow the same design strategy as seen in the Galaxy S6. However, the Home button will undergo slight modification for a rectangular shape and the SIM card slot will be repositioned to the side of the device.

From what we have heard so far, Samsung Galaxy S7 is expected to beat all benchmarking scores and feature top-of-the-line specs. It will likely run on a newer Exynos 8890 octa-core processor while Qualcomm's 2.2GHz Snapdragon 820 chipset will power another variant based on the markets. There is going to be a 4GB RAM, 64GB storage, microSD card slot and a 2,550mAh battery. The screen resolution will likely be set at Quad HD or 4K and the camera will be improved to a 23MP Sony IMX300 sensor with flash.

Samsung is expected to unveil the new flagship during its Unpacked 2016 event on February 21 in Barcelona.
