MacBook Pro 2020 (M1) camera is worse than my MacBook Air 2019

The camera on the new M1 MacBook Pro 2020 should be as good or better than the MacBook Air 2019. If you have an Apple Store near you, it is time to set up an appointment to have it looked at by a Genius; if not, I would suggest you reach out to Apple Support and see how they would like to assist.

I can't say for sure if there is something wrong with your m1 MacBook pro.

But I can say that the camera on it should be on par or better than the 2019 MacBook Air
