I’m sure a lot of regular photographic techniques apply, but what might be some specifics to keep in mind with smartphone cameras in particular?

For example, would camera app choice make much difference, or is stock preferred as being more likely to have the most access to the camera’s hardware/sensors? What are some ways to mitigate or prevent any automatic “improvements” to photos taken via smartphone outside of whatever simple settings stock camera apps may provide?

Regarding that last question, might that be the breaking point where one might prefer a more dedicated camera over a smartphone’s camera?
