Design, performance, and enterprise are the three major schemes for Samsung at MWC 2015, the company demonstrated its flagship Galaxy S6/S6 Edge. Instead of rolling out flagship, LG emphasized its four new entry-level to mid-tier handsets.

Technically speaking, the Samsung Galaxy S6 is 6.8 mm thin and weighs 138g, while the Samsung Galaxy Edge is 7.0mm and weighs 132g. In terms of specs, the S6 sports a 5.1 Quad HD Super AMOLOED display with 2560 X 1440 resolution which comes to a very high 577ppi pixel density, while the S6 Edge also sports a 5.1 Quad HD Super AMOLED but with dual edge display. Both use Corning Gorilla Glass 4 for protection.

The devices are powered by Samsung's Exynos 7 Octa-core processor which contain two quad-core processor clocked at 2.1 GHz and 1.5GHz respectively. The smartphones have 3GB RAM.

Both flagships of Samsung also use the 14 namometer (nm) mobile processor with a 64-bit platform, new LPDDR4 memory system and UFS 2.0 flash memory which the company claims, will provide higher performance and enhanced memory speed with lower power consumption.

There is no doubt that Samsung is in the leading status judging from above handset key components, which make S6/S6 Edge work better than other competitors in terms of processor speed and power-consumption performance.

Meanwhile, HTC rolled out its flagship M9 at MWC 2015, and it was considered the world's most beautiful disappointment.
