Samsung Galaxy S7, the next flagship from the South Korean giant, is expected to be announced at the beginning of 2016. Rumors say the handset will be ready by the end of 2015 and it will be available for purchase in January.

According to Sam Mobile, since Samsung will be switching to the Agile developmental methodology for building the Galaxy S7, the device is expected to release one or two months in advance. The Agile methodology splits a new project into smaller modules in a bid to complete each one at a faster pace.

Whenever a module gets completed, it is immediately evaluated, allowong engineers to make midway changes quickly. On the other hand, the Waterfall method follows a precise plan and once a module of the project is completed it does not allow changes easily.

Samsung is known for announcing its Galaxy S lineup of smartphones at Mobile World Congress. However, Agile methodology will make it possible for Samsung to release the Galaxy S7 earlier in January. Hence, rumors are claiming that the smartphone will be showcased at the Consumer Electronics Show.

Samsung is expected to announce the Galaxy Note 5 and the Galaxy S6 Edge Plus Thursday ahead of the September debut of the iPhone 6S and the iPhone 6S Plus.

If Samsung releases its Galaxy S7 early, it will be able to beat its rival brands like LG, Sony and HTC that are known for releasing their flagships around the end of the first quarter or during the second quarter of the year. G for Games reported leaked internal documents from Samsung suggest that the Galaxy S7, codenamed Jungfrau, will be powered by Snapdragon MSM8996 chipset. As of this writing, there is no official confirmation from Samsung on the existence of the device.
