Would you mind running the diagnostics tool in your Samsung Members app, and testing the camera out? Let us know if the tool finds anything!
Additionally, I need to ask - have you been using Pro Mode to shoot your photos? Asking as it may be because your white balance might be causing the yellowish tint on your photos. Try playing around with pro mode and see if changing the white balance solves the yellow tint issue for you.
I also have this issue, especially on low lighting photos. It makes the skin really yellow and too saturated. This issue only happened when I upgraded in OneUI 6.0.
Many people from Galaxy A54 FB Groups that had upgraded to OneUI 6.0 also had this problem. I hope this will be fixed ASAP.
