The Blackphone 2, the second device from the Swiss company Silent Circle, is unique. It promises a fully private experience, with advanced security features, deep permissions management, and encrypted voice, text, and video chat built in. The phone, which runs a heavily modified version of Android, lets you fiddle with the most granular permissions settings of all your apps, giving you a level of privacy control that far exceeds that of regular Android phones. And when you make a call, send a text, or fire up a videoconference, your communications travel encrypted across Silent Circle’s private cloud VPN, better protecting you from spies.
