Both Samsung Galaxy Camera 4G and Nikon L820 have 1/2.3-inch sized 16.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the Galaxy Camera 4G and L820 sensor size comparison.

Samsung Galaxy Camera 4G and Nikon L820 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Samsung Galaxy Camera 4G
or the
Nikon L820 ,
including hyperfocal distance.
