Default Completely black / dead camera

I've seen some people report black lines on their camera applications but my issue is that off location tracking inside the camera app itself since again I can't access the damn thing. The camera won't boot at all I just get a black unresponsive screen no matter what I do. I've tried most of the stuff suggested on xda including turning setting my location service to gps only, turning off Wi-Fi (I can't disable Direct and Direct Share because it won't let me ) as well as clearing the app data & cache). What l can't try is turning off location tracking inside the camera app itself since again I can't access the damn thing. Any help would be greatly appreciated. As aside note I've installed the KitKat update so I'm running 4.4, still nothing.

This seems like a hardware issue...
