I do not understand how is calculate 21 Mpx for camera

Hello

Features for Xperia Z3, there are:

camera

     20.7 Megapixel camera with autofocus
     2.2 MP front camera
     ISO 12800

When I take a picture of the front, the image is 1920 * 1080, = 2 073 600 pixels, which does not exactly match 2.2 MP.
But with a photo taken at the back, we get 3840 * 2160 = 8 294 400 pixels. Is far from the 20.7 million pixels.

Is there a mistake in the definitions of the characteristics?

To change the quality manual auto, type right on the yellow circle with a camera and an i inside, then select Manual (M).
