LCD Screen Size and Features
Canon G12's 2.8" LCD screen is slightly larger than Nikon S31's 2.7" screen.
Moreover, Canon G12 sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. On the other hand, Nikon S31 has a fixed type screen which provides almost no flexibility in shooting positions compared to G12.
