I know this type of post has been posted before however nothing from there has helped and I don't think I can reply to that post.

Ever since I got the phone the function has never worked. I'm worried its a hardware issue and if so it'd be probably difficult to prove. I've tried turning off the camera access for all apps but no success, I haven't installed any apps that I can think of that could be preventing the function from working .

Has anyone else had this issue? Could it just be a bug fixed in a future update or more of a hardware issue?
