Its all about how you use the phone to take pictures in low light condition and keep in mind that such a small sensor has its limits

Check the link above, I get great pictures in low light but you have to change the manual settings, I even get bettery pictures than my friend's S4 but again, that's my experience, still not quite near lumia but its decent
You have to be realistic on what a phone can do with such a small sensor, don't expect a DSLR like pictures or point and shoot cameras
