Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Samsung Galaxy NX and Nikon S9300 side-by-side from the front, back and top in their relative dimensions. Samsung Galaxy NX has external dimensions of 137 x 101 x 26 mm (5.39 x 3.98 x 1.02″) and weighs 495 g (1.09 lb / 17.46 oz) (including batteries). Nikon S9300 has external dimensions of 109 x 62 x 31 mm (4.29 x 2.44 x 1.22″) and weighs 215 g (0.47 lb / 7.58 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung Galaxy NX and the Nikon S9300. Nikon S9300 is 28mm narrower and 39mm shorter than Samsung Galaxy NX but it is also 5mm thicker. As you can tell, actually this is not a fair size comparison since Nikon S9300 has a built-in lens but Samsung Galaxy NX doesn't. Once you put a lens on Galaxy NX, its thickness will increase significantly.
Here is the back view size comparison of the Samsung Galaxy NX and Nikon S9300.
Now lets look at the top view comparison of Samsung Galaxy NX and Nikon S9300.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S9300 is significantly lighter (280g ) than the Samsung Galaxy NX which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on Galaxy NX, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Samsung Galaxy NX nor Nikon Coolpix S9300 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Samsung Galaxy NX's 4.80" LCD screen is slightly larger than Nikon S9300's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
