What is misleading? 
Isn’t the 1080 (real amount of horizontal pixels of my phone) less than 392 (value calculated by kodular - width). Yes, it is. I doubt there are many screen nowadays on android phones which would make possible to reverse that dependency.
Your post is much more misleading. DPI value unit is dots (pixels) per inch. Width or height units are just pixels not DPI values. Simple math.
The Android system helps you achieve density independence by providing density-independent pixels (dp or dip) as a unit of measurement that you should use instead of pixels (px).
That’s the value you were probably talking about and that’s the value kodular probably use.
