The Samsung Galaxy S7 is expected to release at the beginning of 2016. Rumors are rife that the device will be launched in two chipset variants, one featuring the Snapdragon 820 chip from Qualcomm and other featuring the home-baked Exynos chips.

According to G for Games, the South Korean tech giant is rigorously testing the Galaxy S7 with Snapdragon 820. Early rumors suggest that Snapdragon 820 variant will be aimed towards certain overseas markets, while the Exynos chip variant will be released for the South Korean consumers.

G for Games further stated that Samsung is actively testing the Snapdragon 820 chip at its labs in order to confirm that the newer chip is free from overheating problems. Since the Snapdragon 810 chip was marred with thermal heating problems, LG launched the G4 flagship with Snapdragon 808 chip, and Samsung launched its Galaxy S6 with Exynos 7420 chipset.

The Snapdragon 820 will not feature the Cortex-based architecture like the predecessor Snapdragon 810 and 808 chipsets. It will be coming with an eight cores of Kyro processor. Other rumors suggest that the Snapdragon 820 will come with four Hydra cores and Adreno 530 GPU. The processor will be built with 14 nm FinFET technology.

The Samsung Galaxy S7 is codenamed as Jungfrau, and it is expected to arrive with Android 6.0 Marshmallow OS onboard, Android Geeks reported. In order to achieve better sales, Samsung launched the Galaxy Note 5 earlier this month, instead of clashing its release with the upcoming iPhone 6S in the next month.

Samsung has been consistently using the Mobile World Congress (MWC) platform to announce its Galaxy S series flagship. The same platform is also used by other Android OEMs to announce their flagships. However, in order to have an advantage over its rivals, Samsung is poised to announce the Galaxy S7 in January or February 2016.
