well I was in the same situation, it was a brand new device, i thought I coul repair the broken USB like I did with mine but I was wrong, cuz the camera rubber was cuted so dead forever, he told me that it was a faulty camera app... well now I keep it here waiting, if ever my screen broke (i touch wood) i'll replace it
So try to ask him if he already tried to repaire it.
hope this will help you
