Camera app not working

[Android Central Question]

Hello my friends,
Recently, I realized that when I open my camera app it says “Can not connect to the camera”

Actually, I thought it would be disabled. But I didn't find “Camera” in my applist.

You might say that it's in disabled apps but Its not there too. (In my desire 816, to access disabled app you should swipe to right but you see I have no disabled app)

Please give me a solution...

The camera module may have failed.
