There is the occasional need. The other day while the sun was setting and my wife and I were indoors, we each decided to take a pic. Her with the Lumia 1020 and me with the Lumia 925. Her's is damn near a DSLR camera and mine is a simple 8MP camera with no IOS, no Xenon flash, no double flash, but does have Carl Zeiss lenses. Mine came out with a lot of noise. My wife's picture was damn near perfect. No distortion or noise until you really zoomed in to the individual pixels. So, if I have a 1020, it doesn't really matter when I take a pic. If I have another phone, I probably won't bother taking the picture, which means losing a potentially great moment.
Yeah I do, especially when I'm walking around rural areas at night where there's only a small amount of light but some amazing things to see. To be fair enough even my S4 ****s that up, either I see nothing or I use the flash and it's far too bright to look nice.
Thanks guys for your feedback, I like to hear other people's habits so often it's easy to fall into the trap of thinking your own behaviour is same / applicable to others and that whilst can be true it is not always the case
