The only thing megapickles really bring to the table is crop-ability, these days. 12 should be fine for a point and shoot, given the small sensor size.
Not really. The more information the software has to work with, the better it can compose a picture. And what you're failing to understand is that, unlike DSLRs and other cameras, smartphone photography is HEAVILY based on software due precisely to the space constraints of a phone.
So, a phone with only 12mp will have a lot less information to work with than one with 16 or 23mp. That has been made abundantly clear with the S7. Because it has fewer megapixels - and therefore less information - it resources to tricks like over-sharpening to try and produce a picture more clear than that which the 12mp shooter alone couldn't.
You can take as an example a photo taken with the S7 and one with the Nokia 1020*.
The Nokia 1020 has that 41mp sensor. But it produces 2 photos. One with 5mp and another with 34mp. The 5mp image is an oversampled one. That picture is however a lot more clear than one out of an actual 5mp camera. Why? Because it was composed based on the information captures by the 41mp sensor. Actually, it produces a much naturally sharper picture even than the S7 with 12mp. Because of that.
Now, on the S6, Samsung was able to also produce pretty sharp pictures (without the ability of extreme zooming of the 1020 of course) which were pretty pretty similar those produced by the S7 in terms of low light. However, the S6's pictures didn't suffer from any over-sharpening because it wasn't necessary. The camera was capturing enough information.
Samsung made a gamble with the S7 camera (although to me it seems more like a "let's copy Apple and try to beat them with the same hardware" sort of thing). I don't think it paid off. And if I had to bet, I'd bet that the camera on the S8 will again jump to a better sensor with more megapixels.
To me, the only way cameras should be going was up. By now the standard should be 20mp. Not 12mp. Larger apertures are possible on both and as HTC had already proven with the UltraPixel fiasco, larger pixels on smartphones don't really pay off.
(*I know I'm using the 1020 as an extreme example. I could say the same for the Nokia 930 or any old Nokia smartphone which used the same process. I could also have used Sony as an example, but I avoided it on purpose because Sony is the perfect example of how pointless it is to have a 21mp camera when your software is utter crap. If however you had the sensor on Sony's Z5 line with Samsung's software - and OIS - you'd have a bloody brilliant camera that would most likely beat the vast majority of PAS cameras the same way the Nokia 1020 did.)
