Samsung's next flagship phone, the Galaxy S5, is expected to debut in January, according to a Korean website Naver citing sources inside Samsung. The report also suggests that the company might have advanced the release date, owing to its disappointing sales with the Galaxy S4.

Despite the Galaxy S4 surpassing the sales record held by its predecessor, Samsung is reportedly displeased with the sales figures as it fell short of the target. As GSM Arena notes, this could be the precise reason why the company chose to debut the next Galaxy smartphone in mid-January, instead of its proposed launch in March 2014.

With the market release for the smartphone tipped for February, it makes sense to unveil the device a month earlier.

The Galaxy S5 is expected to ship with 64-bit Exynos 5430 chip based octa-core processor with Heterogenous multi-processing capabilities and in line with trend it is likely to run Android 4.4 Kit Kat out of the box.

Apart from a powerful processing unit, the smartphone is said to offer an improved 16 megapixel camera with enhanced low-light and Optical Image Stabilisation (OIS) capabilities. The company recently unveiled its ISOCELL image sensor, which is touted to debut on the forthcoming flagship smartphone.

The Galaxy S5 is also expected to feature dust and waterproof capabilities, besides the possibility of introducing fingerprint scanner into the mix.

There is no official word from Samsung on either the new device's price or its release date. If the past is any indication (the Galaxy S4 was introduced ten months after the S3 was released), the company is likely to push another hardware upgrade to its flagship smartphone early next year.
