Xiaomi Xiaomi, Yes Papa. Secretly Uploading Pics? No Papa!

The news caused havoc among the users after GSMArena, a popular mobiles focused blog picked up the news. Since then, Hugo Barra has come out in public and made it clear that Xiaomi Redmi Note is a safe device to use and it does not upload anything to the Chinese server. He made it very clear that Xiaomi phones will not upload anything to any server silently and the company respects user privacy and all the laws of the land where the Redmi Note is sold. The Mi Cloud service allows users to back up their data on the server but users have the option to disable it. Users can go to Settings -> Mi Cloud and turn it off.

We'd like to know from our fellow engineers their opinion on user privacy. There's a ton of data that several companies track for each of the users. For example, Facebook and Google know almost everything about you - right from what you like to eat, what's your prefered style and color for your clothes, when you sleep and get up and what are you up to these days. Do you think users are still in complete control of their privacy?
