iphone 15 pro front camera terrible

I have upgraded my mobile from 11 to 15 pro and it amazes me in a bad way without any logical answer. The quality of front camera is so bad, even worse than my Ip 11 and IP 6 years ago. It look totally fine in the screen but then when I take the sefie, the result get darker, less sharp as if I take it in the dim. Everything looks more grey.

with the back camera, it’s totally fine with the sun shine but when the weather is not good enough, the people in the picture look like they have come back from the death with extremly pale skin and lips. It didn’t happen with ip 11.

so what should I do to fix this? Will Apple try to fix this?
