BGR has exclusively learned several additional details about the heavily customized Android software that powers Amazon’s smartphone. Multiple trusted sources tell us that Amazon’s upcoming handset will utilize a unique combination of cameras, sensors and software to dramatically change the way users interact with a smartphone. As we detailed in an earlier report, the company’s first smartphone will feature four low-power infrared cameras on the face of the device that track the position of the user’s head in relation to the phone’s display. This unique hardware combination of tracking cameras and sensors will facilitate a variety of 3D effects on Amazon’s smartphone, as we reported. These effects will be present in several stock Amazon apps as well as some third-party apps available for download from the Amazon Appstore.
