Hello @emma1992xXxX
Please consider going over to your dial pad and type in *#0*#, this will bring up a number of tests to try.
Make sure the lens is clean.
If they don't help then seek support from a Samsung Experience Store or Samsung Service Centre.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
