Sorry, but this is the one feature I hate (not being able to turn off) on today's phones. All the wannabe HDR, noise reduction, upscaling, color corrections that make the pictures look plasticky and overly colorful and just plain kitsch when compared to the same scene taken with a 10-15yo pocket camera.
