You should not click photo in 200 MP mode when ample amount of lighting is there. Try to click in 12 MP mode. 200 MP is for professional and for low light pictures. As i also faced earlier the same issue. But since 12 MP is clicking awesome pictures,...

Lekin bhai mujhe ab chaiye hi nahi update 

Download camera assist app from Good lock and there you'll find auto hdr. Turn off auro hdr also

I think 200 MP clicks best when there is low light outside. However for general purpose you should use 12 MP camera. You can also off post processing or Super HDD in setting option in Gallery app.

There is no feature of Auto brightness in AOD settings in S24 ultra
