ZTE's Grand S II already looks like a pretty fine handset with its brushed metal back and Snapdragon 800/801 CPU, as we saw at its launch earlier this year. But judging by a leak at Chinese regulator Tenaa, it could take it up another notch with 4GB of RAM -- a first for any smartphone and double the original spec. That's the maximum possible RAM on a 32-bit ARM chip, and 4GB modules were only recently teased by Samsung and SK Hynix. We wouldn't be surprised if it ends up as a high-end option for the Grand S II, in the same way that ZTE's Nubia X6 is available in a 3GB RAM variant. Take all this with a grain of salt for now, but remember that until we see a 64-bit CPU and Android OS, 4GB will be as good as it gets.
