The $850 Archos GranitePhone promises to keep all your data secure

The Blackphone isn't the only smartphone out there that has security as its number one feature. A partnership between Archos and secure software specialists Sikur has yielded the GranitePhone, a device that runs Sikur's fully encrypted GraniteOS on top of Android. As its site claims, the GranitePhone encrypts every bit of communication data on the device, including calls, messages, contacts and more. While the device has Android at its core, it doesn't look like it includes Google's service, including the Play Store -- so it's not likely to appeal to anyone except those who really put security at the forefront.

Then there's the cost -- $850 gets you decidedly mid-range specs, including a Qualcomm Snapdragon 615 chip with 2GB of RAM, 16GB of internal storage and a 2700mAh battery. The 5-inch screen runs at 1080p, while the back and front cameras come in at 16 and 8 megapixels, respectively. Most of the users in the market for this device likely aren't concerned about the rather pedestrian specs, though -- it's all about the encryption here. Unfortunately, the GranitePhone site only gives minimal details about what the experience of using the device will actually be like, so you'll need to know that Sikur will do what you need it to before you plunk down your hard-earned cash.
