Hype around Samsung's upcoming flagship smartphone, Galaxy S6, is gaining momentum with its release date drawing closer. Expectation on the device is sky-high with rumours suggesting drastic feature upgrades over its predecessor but it could also disappoint fans like Galaxy S5 if it doesn't come with the speculated specifications.

Galaxy S5, which was released in April this year, was a big disappointment and it failed to make good business for one big reason – several features, including display, processor and design seen in the device were inferior to what was being speculated.

Now, the big question is – will Samsung Galaxy S6 live up to the expectations of its fans?

Going by the reports that have surfaced so far, it seems Samsung is working hard to bring drastic changes to its upcoming next-generation smartphone with several upgrades to woo its fans back, but one still can't rule out the possibility of the device disappointing fans, like Galaxy S5.

According to AnTuTu benchmark, as reported by Mobifo (via SamMobile), Galaxy S6 is expected to come with a qHD screen with 1440 x 2560 pixels, 15.9MP camera, octa-core 64-bit processor and Android 5.0 Lollipop.

However, AnTuTu benchmark of the device reported by Chinese website CNMO (via Phone Arena) claimed that Galaxy S6 would sport a 5.5-inch display with 1440 x 2560 pixels, powered by Exynos 7420 processor and run on Android 5.0 Lollipop. It added that the device would have a 20MP main camera and 5MP front snapper, and 32GB of internal memory and 3GB RAM. 

Codenamed as "Project Zero," Galaxy S6 is expected to be unveiled at the Consumer Electronics Show 2015 (CES 2015) in Las Vegas in January, according to a report by Korean website Chosun Biz (via GforGames) quoting analysts at Mirae Asset Securities (MAS). 

Indian import tracking website Zumba also claimed that the device with model number SM-G920F will be sent to India for research, development and evaluation, hinting that its release date is not far off. 

It was earlier reported that the device would be unveiled at the Mobile World Congress (MWC 2015) in March.
