Blackphone

Blackphone offers a mostly secure Android-based smartphone for $629

While its final components might be altered later, right now the developers are aiming to equip the device with a 2GHz quad-core processor, 4.7-inch HD IPS display, LTE connectivity, 2GB of RAM, 16GB of storage (no microSD card slot in sight), 8-megapixel rear and 1.3-megapixel front cameras.
The Blackphone will come loaded with a derivative version of Android called PrivatOS that's supposedly more secure, and it'll be bundled with two-year subscriptions to a few privacy tools. These include Silent Circle's encrypted app suite (for messages, calls and contacts), a VPN, anonymous search and browsing tools, and secure cloud storage. You'll also get a free Wi-Fi analyzer and a remote wipe and recovery tool.

The device will provide end-to-end encryption for Blackphone customers who interact with each other. For messaging from a Blackphone device to a non-Blackphone, there will be a one-way encryption that occurs from the Blackphone side to Silent Circle servers.
Additionally, Blackphone can mask what information and block apps from obtaining private information. In one example, if an app requires access to the phone's address book, Blackphone can intercept that request and tell the app that the address book is empty.
