One thing I noticed was how consistent the iPhone photographs were across all shooting situations.
With the Samsung, some shoots seemed overly warm, others had a slight blue-green cast. Looking at the outdoor shot with the grass, and the low-light outdoor shot, I had a hard time believing that Samsung hadn't applied some HDR processing. You normally don't see that much detail in the shadows AND the highlights without combining multiple exposures.
Overall, I'd say Samsung has done an admirable job, but they're not quite there. The inconsistency and "over-processed" feel to many of the photos is not what I look for in a camera. I prefer more even exposure, consistent colour, and neutral shading that I can tweak in post-processing myself.
No mention of iOS having accurate color management and calibrated Wide Color P3, which Android lacks?
That explains in part why the "beauty mode" and random oversaturated nature of Samsung's pics are so inconsistent. Apple controls the hardware and the OS. Samsung doesn't.
