Hi, Aaron.
First try to connect your camera to a PC and see if it is recognized by the PC; and if the camera shows any reaction. Based on your description, it appears not to be a power or battery issue. However, Samsung has identified multiple software glitches since release that, depending on how they manifest, may render the camera inoperable.
If the camera makes a connection with your PC, please visit Samsung's support page and update it with the latest software; this often restores the device. However, it the PC is does not connect with the camera, I would suggest to either contact Samsung support or, potentially, replace the damaged(?) motherboard on your device.
Hope everything goes well.
