Something is definitely not right if the front/selfie camera isn't working. They are fine on mine with the original camera app (I don't use it, I use Open Camera). I would contact FxTec. It might be that they could send you a new top (display and frame, which includes the front camera), which is pretty easy to install (5 screws and a ribbon cable). They may or may not have immediate availability of that part, so there could be a wait, but check and see.
