iPhone 6s front camera not working

[Jezza23]

It might sound weird, but a friend of mine has a 6s which, by unknown reasons to me, went under the wheels of a moving car. It didn't crack nor fail, but the front camera is showing no image at all, only black. So, is there any way to solve this problem or should she change the phone?

I don't think there is a solution, but I suggest taking it to an Apple Store for assessment. If they can't fix it, she will have to replace it.
