A leaked screenshot possibly revealed an updated Pro version of the alleged Xiaomi Mi Note 2-series. It might come with up to 8 GB of RAM, up to 256 GB of storage and a faster 2.6 GHz processor. The question is: when will it be released?

Not sure whether there will be a RAM limitation after the OnePlus 3 was not using the 6 Gigs of RAM, at least I heard, to the full capacity.
