Will we see 3GB of RAM on Samsung's 2013 high-end smartphones?
Prototype handsets suggest Samsung is testing a phone with no buttons and 3GB of RAM
The current version of Sammy's flagship model offers 2GB of RAM which is something that is being used on the highest of the high-range models like the LG Optimus G. And the buttonless look is merely the result of years of smartphone evolution. We will probably look back in a few years and laugh at those smartphones sporting 'just' 3GB of RAM and marvel how we got by so well and for so long with such low spec'd models.

UPDATE:It should be pointed out that despite the sticker reading Gb, the source says that it does stand for GigaByte, not GigaBit. The stickers are, of course, for internal use only!
