Guesswork, Rob? No guess work with mine.
I always crop in the camera and frankly I far prefer the full shot. It is more descriptive to me whereas the crop becomes a catalogue shot.

My cell's a Samsung Galaxy Ace - aka S5830, and I can assure you that outdoors, in the usual sunshine, it's impossible to see much of anything at all. Shooting into the light, the only indication I have of content is where I can pick up some highlight on the sea, and I extrapolate content sideways and vertically from there, which since I'm always guessing the acceptance angle of the thing, isn't a huge help. It's perfectly ok indoors, but definitely not so most of the time outside. Ironic, since it has a lovely big sreen! I'd have imagined (and did!) that shooting into the light, which means that the dark side of the world is behind one, would have made viewing acceptable, but no. These things need a viewfinder!
I don't like cropping, either - the result of much 35mm working.
