Samsung has hogged the headlines since the beginning of 2013 with its Galaxy S4 smartphone. It seems the company won't stop with the Galaxy S4, as recent news suggests that the Korean company is going to introduce a new brand for its upcoming 5.8-inch and 6.3-inch phablets, to be called Galaxy Mega.

SamMobile reports that the upcoming Galaxy Mega phablets are already in the works and won't be part of the Galaxy Note Series.

"Samsung wants to introduce 2 smartphones with big displays. The Galaxy Mega 5.8 code named GT-I9152. This code directly hints on a big DUOS smartphone based on Android with a display size of 5.8". The other expected mega device is the Galaxy Mega 6.3 code named GT-I9200. The display of the Galaxy Mega 6.3 is expected to be 6.3", this display size was previously rumoured for the Galaxy Note III," reports SamMobile.

SamMobile also notes that Samsung recently launched GamePad, an accessory for the Galaxy S4. The GamePad can handle devices up to 6.3 inches, which indicates that Samsung is planning a 6-inch-plus device.

The Galaxy Mega 5.8 is expected to come in white and has a purported release date of around week 22 of 2013 (between May 27 to June 2). The Galaxy Mega 6.3 is expected to come in two colors: black and white, and the device has a speculated release date of week 25 of 2013 (between June 17 to June 23).

Samsung holds the top position in the global Android market. The year 2012 was very successful for Samsung smartphones, with the Galaxy S3 and the Galaxy Note 2 making a strong impression on both smartphone enthusiasts and tech gurus alike.

Many eager smartphone buyers are keenly waiting for the release of Galaxy S4, which is due end of April. Samsung has not revealed any information on the bigger 5.8-inch and 6.3-inch phablets and therefore, we will have to wait and watch until the company makes an official announcement.
