The rumored device is expected to include four low-power infrared cameras on its front side. Those cameras will allow the gadget to display 3-D effects on the phone's screen, as previously reported.
But on Tuesday, tech news site BGR said that those cameras will also help the phone recognize the way users tilt it.
By recognizing different tilts, the device will be controlled by users moving it around in different directions. The phone is also expected to have a 4.7-inch touchscreen, so users will be able to perform touch gestures as well.
It's unclear when the device will officially be announced and released.
Citing unnamed sources, BGR said it expects Amazon to unveil the phone later this spring, while the Wall Street Journal earlier this month said the company hopes to announce the gadget by June at the latest.
Amazon could not be reached for comment.
