What can I do to make my front camera work

I have this same exact problem my front camera does not work ever and when I try to answer or make a WhatsApp call it does not work it automatically hangs up. I’ve restarted my phone and closed the app but it still does not work.

my phone also have the same problem but I try recommend go to fix it or use back camera I use back camera it work

Then I recommend to fix it when I need to do important stuff I turn back camera to front but I can’t see the phone
