I guess that the increase in resolution (8mp -> 12 mp) while keeping the same sensor size did not increase the low light performance...well, that was to be expected...but to me it seems it did not even keep up with that of the iPhone 6...which could also be expected, but is still sad...as a general rule of thumb: smaller pixels=lower quality pictures in low light (if the sensor is from the same generation, but it seems that the technical improvements did not compensate the shrink form 1.5 to 1.22 µm)
Anyway, as no reasonable person would expect a mobile phone camera to replace even a premium compact (at least currently) unless one operates only in optimla conditions (optimal for the phone camera that is) and that it will never reach the versatility of a full frame, aps or mft camera...it still has that one magic sentence going for it: The best camera is always the one that you are carrying with you!
