Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon L31 is significantly lighter (90g ) than the Samsung WB850F which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix L31 nor Samsung WB850F provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Samsung WB850F's 3.00" LCD screen is slightly larger than Nikon L31's 2.7" screen.
