Where did you get your device from? I just recently received a black 64GB model from negri electronics and I have those exact same black spots on mine. Another weird thing with this device is that when I opened it and started it up, the default pics/videos were all missing. The box was sealed and everything. But to have those exact same spots you are is kinda of weird to me. Also this one doesn't have a dark pink hue/tint on the side. There is a slight tint. Better than the previous one I had.
