How can I maximize my galaxy A25 camera?

I don't like the photos and videos of my Samsung galaxy a25, I think it's over saturated and over contrasted. I know my phone have a not so good cam, but I want to maximize its camera's capability. I want it to have an accurate color representation. I want it to more natural looking, not too sharp, saturated, and contrasted. Please help me do it. Tyia!!
