After being taken to task by the BBC's consumer rights show, Watchdog, Samsung says it's looking into reducing the memory footprint of its TouchWiz features on its flagship Galaxy S 4. A spokesperson told CNET UK that Samsung, "appreciate(s) this issue being raised," and that it is "reviewing the possibility [of] securing more memory space through further software optimization." The 16GB GS4 offers only 9.5GB of space for users to fill, but at least we know it's a possibility: Google announced yesterday that Samsung's Galaxy S 4 will arrive in an entirely vanilla Android guise this June. We've got the full statement from Samsung after the break.
