Silent Circle's second-generation smartphone, the Blackphone 2, runs like any other Android phone -- with a twist. Its Security Center feature helps you lock down your device to prevent hackers from gaining access to your sensitive data.
The phone has Qualcomm Quick Charge 2.0, which the company says can charge the battery to about 60 percent from zero in as little as half an hour. In field testing, the phone made good on this promise, give or take a few percentage points.
It's worth noting that the device's modestly sized back-facing loudspeaker was difficult to hear when out and about on the streets of London. Even in quiet spaces, listening to music was difficult at times, because of the position of the speaker and its limited maximum volume.
The Blackphone 2 boasts a crisp and sharp high-definition display, making 1080p videos look stunning and perfectly rendered. The smartphone has 32GB of internal encrypted storage for documents and files, and a 128GB expandable card slot for music and videos.
