I use Samsung’s stock android photo app.
Even tho, I’ve done a HAND BETEC in Photography, I don’t use any pro software or even a dsl. I have a cybershot bridge camera that I use for taking “proper” photos, but 90% of my pics, I use my S8 on auto mode and find it very good, not just as a phone camera, but as a point n shoot camera (as good as any £100 compact camera).
I dont even use colour adjust or adjust white balance.
For taking pics for fb or showing on my phone, it’s perfectly fine. I think my old training n having a decent “eye” helps me take better pics. I find friends who do have dsl cameras compliment me on my pics.
I think what makes a big difference, is that I don’t have a laptop or desktop, just my handset.
