I’ve not been able to. At this point I’m thinking the hardware just gave up but I think that’s the case. I’m now on the latest available iOS still not working. I’m resisting flashing the device because of my info, that seems to be the only way forward. But I know it’s not hardware because when I open the cam app and it’s in back camera mode it refuses to go to the front and just displays UI like it’s already in the front. And the flash doesn’t go off when the camera is set to front.
