The camera of my Samsung galaxy A11 is not working.  It doesn't even come on and whenever I tried making a video call on watsapp only the rear camera works. How do I fix this

Hi, try using it in safe mode. Ifyou get no joy, it's hardware failure.

Search Google for best android camera apps, check if the app is in Play Store and download.
But BEFORE you do, Google "galaxy camera not turning on" and check some of the solutions there.
