I use a Nikon DSLR camera when I want to take decent pics. I've never been a fan of phone cameras, even as much improvement as there has been. They simply don't take pics like an actual camera with like an actual camera lens. Only date and time in that file.
Just like with car engines, there's no replacement for displacement, with cameras there is no replacement for an actual camera lense. Those flat lenses on phone cameras simply cannot compete.
It's also the size of the sensor. You can pack a huge sensor in an SLR.
