Beyond those two units, the device houses an additional four front-facing cameras that work with other sensors to facilitate the software’s 3D effects. One source tells us these four cameras, which are situated in each of the four corners on the face of the phone, are low-power infrared cameras.
The device’s extra cameras are used to track the position of the user’s face and eyes in relation to the phone’s display. This allows Amazon’s software to make constant adjustments to the positioning of on-screen elements, altering the perspective of visuals on the screen.
