I got this same problem with my Oppo F1S A1601 phone. the camera is shown upside down. and the camera lens change is greyed out. I need help with this too.
its easy open up your phone and unplug and plug the cam again and after rebooting it will work just fine and if it still gives an error just replace your cam and mostly this error comes in back cam and affecting front cam as well…
