One of the most predictable smartphone companies in terms of release is Samsung. Its Galaxy S line gives birth annually, and fans are eyeing the S6's arrival in 2015. The Galaxy S5 came April this year, and is currently the company's flagship device.

Expert Reviews predicts the upcoming launch to come a few weeks after the press event, hinging on what happened with the S5. The smartphone was revealed at the Mobile World Congress (MWC) show in Barcelona. The source estimates a Mar. 2, 2015 possible launch date for the S6, if Samsung goes with MWC again.

TechRadar, in a report, agrees with Expert Reviews' prediction. The launch date could also be a month earlier. GalaxyS6Samsung said that it might be on Feb. 2015.

The Epoch Times reported that "some metal" will be in the device, as the recent Galaxy Alpha sported metal ware. Alpha's branding tagline which reads, "Just Alpha. Style. Slim. Metal", exudes Samsung's use of what's perceived to be a premium material.

The S6's display is potentially UHD at 3840 x 2160 as Christian Post reported that it has been chosen over QHD (2560 x 1440). The source added that the S6 might be needing a Snapdragon 810 chipset, should the device sport UHD. 

PC Advisor reported that the device's metal material could be graphene, a low-weight carbon. Other rumored specs and features also include a SuperAMOLED screen, a flexible or curved display, Android L, Samsung's TouchWiz interface, Qualcomm's 64-bit processors, and the 16Mp to 20Mp resolution for the camera.

TechRadar estimates the S6's cost to be more expensive than its predecessor. The Samsung Galaxy S5 was priced at $972 SIM free at its launch. The price will likely not go beyond $1000, added the outlet.

Tom Kang, a Seoul-based Counterpoint analyst, refers to the S5 as a product that did not hold up to expectations, reported Trusted Reviews. He said that the company is paying the price and will have to move forward, and focus on the next product.

And it seems that the South Korean tech giant is determined to do just that. "We will strengthen our product competitiveness by reinforcing our premium brand reputation, powerful product line-up, and cutting-edge technology," Samsung was quoted in a Reuters report.
