Hi to all Xiaomi Mi2(s) owners ! I am a newcommer to your community. I just bought a Xiaomi Mi2S and realized that this otherwise exeptional smartphone does NOT have a USB mass storage mode, when it's connected to PC. My previous phones ware HTC and Samsung, and they always have had this USB mode - even after version 4.x оf Android. So, if someone think that USB MASS STORAGE mode is A MUST, please, VOTE !
