My phone isn’t able to do things such as using an app downloaded from the apple store. It cannot use facetime either. I didn’t buy it from a shop , so I’m convinced that it’s fake. Everything else is of an iPhone ,it even functions like an iPhone in most cases.. But the camera isn’t of an iPhone, it has low mega pixels. Can it be fixed?

Well since it is a fake iphone, it is most likely not fixable.
