The rumours about the Samsung Galaxy S5 continue. Rather than another conflicting rumour (it will or will not come with a metal body; it will come or will not have a flexible display, it will or will not include OIS), the latest one reveals what could be its codename. According to the usually trusty @evleaks, the Samsung Galaxy S5 is known internally as K.
Samsung Galaxy S 4 was J. Galaxy Note 3 was H. And the Galaxy S 5 is codenamed K.

Samsung appears to have a fondness for alphabet letter codenames. The Samsung Galaxy S4 was the J while the Galaxy Note 3 was known as H.
Even the launch date is not without conflicting rumours. Most though suggest that Samsung will launch the Galaxy S5 sometime in early 2014, likely in the first quarter.
