LCD Screen Size and Features
Olympus TG-820 iHS's 3" LCD screen is slightly larger than Canon G12's 2.8" screen.
On the other hand, 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, Olympus TG-820 iHS has a fixed type screen which provides almost no flexibility in shooting positions compared to G12.
