The Blackphone 2, even in prototype form, represents a big step up in build quality from the original. It's pretty light, and feels very durable. Unfortunately, all the phones here at MWC are stuck on a demo loop, so there's no way for us to put the new, beefier processor to the test, but the display looks way better than the original's, and the phone will undoubtedly be faster than Blackphone users are used to.

The Blackphone gang also announced that it has tied its devices, PrivatOS Android-based operating system, suite of apps and store together into an "enterprise privacy platform." The company described that as a "vision to drive the second stage of growth for Silent Circle," without laying out concrete details of exactly how everything will work together. However, it did reveal one new service: Along with "Silent" encrypted calling and texts, there's now Silent Meeting for secure business conferencing.
