and what for ?? between 4.1 of Mi2s and 4.3 of Mi3 there isn't any difference, NO; NADA, NIENTE, so what should make 4.4 so different. All the time users that asking for the latest version, but nobody can tell me what are the differences.
There are many good updates in the 4.4 base... WiFi streaming video is now system based, and the support is great.. There are many improvements to the battery consumption.. And last the new update will bring MIUI v6, hopefully
