My Samsung Mega 6.3 is direct from AT&T and included Samsung’s TouchWiz interface. To be candid, this is my first experience with this company’s front-end touch interface – all of my Android device’s have been of the Nexus ilk. With it comes a handful of options and features not found on a Nexus device.
The naming convention for the 2009 Samsung 6 Series: Samsung LNxxB650 where the "xx" is replaced by the television's size. The 2009 models can be distinguished from their 2008 counterparts by the letter that appears before the "750". 2008 is "A", while 2009 is "B".
