ZDNet Korea went a step further by reporting that Galaxy Tab 4 and Galaxy Gear 2 will also be launched alongside the Galaxy S5 at the upcoming MWC.

Reports also suggested that Samsung's flagship smartphone will have several upgrades over its predecessor, Galaxy S4.

2) Galaxy S4 is powered by 1.9 GHz Quad-Core Processor / 1.6 GHz Octa-Core Processor, while Galaxy S5 is expected to have 2.5Ghz Snapdragon805 (main) or 2.0Ghz Octa-core Exynos6 (64-bit).
