They say no publicity is bad publicity but it can backfire if hype and reality don't match. Many smartphones had failed in the market because of disappointing fans by not having features speculated before their release, and the Samsung Galaxy S5 is one of them. Now, it's to be seen if its successor, the Galaxy S6, will follow its footstep or rise among the grown.

Hype around the Samsung Galaxy S6 is so far so good but fans could be left disappointed for more reasons than one when it is launched and here are some of them:

1) High Expectations: Samsung fans will certainly expect big from the upcoming Galaxy S6 following the failure of its predecessor. They will expect it to be a trend-setter like the Galaxy S3 and won't be happy if the device comes with just a few feature upgrades. However, it's not certain that the device will live up to the expectations of its fans.

2) Pre-release Hype and Reality: So much was talked about the Galaxy S5 before its launch with some reports suggesting that even its screen would be protected by sapphire crystal glass, which is second only to diamond in hardness, but it turned out to be just a farce.

Disappointment crept in when reality hits hard and it was reflected in poor sales of the device with the company's profits from its mobile division falling 73.9% to 1.75 trillion won ($1.6 billion), which is the worst performance since the second quarter of 2011. History could repeat itself, if the Samsung Galaxy S6 comes without some of the most-hyped features.

3) Specifications: The upcoming Galaxy S6 should come with an overhaul of its specifications and not just minor upgrades seen in most recent flagship devices if it should woo gadget lovers. There should be major change in key features like processor, camera, screen resolution and memory.

4) Design: Samsung has not moved anywhere when it comes to design of its Galaxy series. The Galaxy S3 was a big hit not only because of its good specifications but also for its design. Samsung fans will expect the Galaxy S6 with a new look.

Meanwhile, it is reported that the Galaxy S6, codenamed as "Project Zero," will be unveiled at the Mobile World Congress (MWC 2015) in March. Phone Arena reported (via Chinese website CNMO) citing AnTuTu benchmark that the device will boast of features like 5.5-inch display with 1,440x2,560 pixels, Exynos 7420 processor, Android 5.0 Lollipop, 20mp main camera and 5mp front snapper, and 32GB of internal memory and 3GB RAM.
