The biggest advantage of S7 camera is in low light situations, and currently, it blows 6s out of the water. Bigger sensor...
'Blows it out of the water'? Oh please, we're talking a crop factor of 6.2 vs 7.2. The cheapest 1/2.3" sensor point and shoot at the camera store has a 5.6, and something like a Sony RX100 has a 2.7. Phonecams don't do lowlight without smearing away all that noise (and your detail), that's true for Samsung and Apple both. If you want to take clean photos at night, you need long exposures or big sensors and faster lenses.
