Chinese smartphone OEMs seem to be beset, warranted or not, by two stereotypes. One is that they are quite talented at "mirroring" the latest design trends. The second is that they can get pretty crazy when it comes to features. Just like this latest leak coming out of the country regarding Vivo's upcoming Xplay 5 smartphone. If one of the rumored details about it is true, then it could very well be the world's first smartphone with 6 GB of RAM, possibly even beating Samsung's Galaxy Note 6.
