It's been years since I'm using good old Nokia because I'm privacy conscious with smart phones. Within mainstream, there's iOS, Android and WP. However, all of the choices in one way or another require sharing a lot of personal information. There is no way to have a smartphone working decently without sharing all of your contacts, calendar appointments, and other stuff with Google. I have found that Ubuntu phones, Boeing Black and Blackphone 2 are currently best in privacy. Not sure about Ubuntu though. Boeing and Blackphone being not open-source, a user just have to "trust" them with privacy. In 2015 is there any option, other than living in a cave, to keep one's own life private while enjoying the wonders of modern smartphones? How are Ubuntu, Blackphone and Boeing Black?
