I bought this phone for the camera but 6 months down the line Samsung still has this HORRIBLE post processing on 50MP and 200MP photos. Very disappointed. My ancient Xiaomi takes better photos

I have an Samsung Galaxy s24 ultra and I am very disappointed in the photo quality when sharing them to WhatsApp or Facebook. What's rhe use of taking beautiful photos and you can't share them with others. Once I share and post my beautiful photos I've taken the quality drops drastically and look all blur and not clear. Very disappointed with this.
