Loving the rear camera. Only complaint is the subpar slow motion '720p' video. Really looks like maybe 480p upscaled, not impressive.
Taking some great shots, quick focus and shutter. Great night auto night shots compared to my S4 and panorama stitches nicely for me in the one or two I've tried.
Front camera leaves something to be desired for me though. I understand there's the beautify filter that's enabled by default, but I notice a pretty bad foggy haze from there as well. Might just be the indoor lighting conditions I've tried with, but not impressed yet.
