While Samsung is scheduled to announce the release date of its upcoming smartphone, Galaxy S6, at the Mobile World Congress in February 2015, a lot of rumors regarding the device's specs are already surfacing online.

In fact, it is important for the South Korean tech titan to do plenty of work to make the Samsung Galaxy S6 a truly premium smartphone, because its predecessor, the Galaxy S5, is deemed to be a less powerful handset compared to other recently released smartphones. Precisely speaking, the numerous handsets launched within a span of just six months from the release of Galaxy S5 have left the Samsung device behind.

While Samsung has yet to disclose the features of the upcoming Galaxy S6, there are numerous rumors about the handset's possible features. Some of the rumored features of the Samsung Galaxy S6 are brought into detail below.

Screen Resolution

The screen panel of the Samsung Galaxy S6 is one of the purported features of the device. It is rumored that this feature will remain unchanged. In addition, there are rumors that the Galaxy S series will not go beyond the 5-inch screen size any more. Nevertheless, the company will up the pixel resolution and will boast 4K screen display with a view to compensate for the lack of increase in size - making Galaxy S6 the first smartphone to incorporate this feature.

Processor

Next year, numerous smartphones powered by Qualcomm's Snapdragon 810 chipset will be launched in the market. In fact, the Snapdragon 810 chipset is the first 20nm processor of the company and it has been designed to compete with Samsung's Exynos 5433 as well as Apple's A8 processors. The new chipset will support both 32-bit as well as 64-bit operating systems.

Operating System

As Google has already announced the launch of its latest mobile operating system, the Android 5.0 Lollipop OS, it is very likely that the upcoming Samsung Galaxy S6 will use this operating system that supports 64-bit chipsets.

Camera

According to reports, the Samsung Galaxy S6 will sport a 20.7-megapixel rear camera. This will be a major jump from the 16 MP rear camera of the Galaxy Note 4.

Iris scanner

It is rumored that Samsung will incorporate the futuristic iris scanner in Galaxy S6. This feature is meant to fortify the security of the device. Nevertheless, it is still not known how this particular feature will be implemented in the upcoming device.
