Several layouts for tablet and phone

Question

I am developing an Android application for tablet and phone . To do this, I created two folders for the phone ( layout) and one for the tablet’s tablet ( layout-sw600dp).

In accordance with my previous questions, comment I assumed that only tablets will select layouts from layout-sw600dp. But it doesn't seem to work.

For devices nexus 4, nexus 5, nexus 6, nexus 7, a layout is performed layout-sw600dp.

What am I missing here? How to calculate phone / tablet size for correct layouts DP?

Another retirement for using two separate layouts:

LinearLayout , :
