This phone has a significantly larger chip than other phones which should translate to lower noise and better dynamic range. DXOmark for mobile phones gave it their top score for still photography:

I am wondering if anyone in the U.S. has this phone and how the camera compares to older phones like Samsung Galaxy S7.
