How limit android app to be installed only to tablet devices ( from 7 )

Question

I would like that my app will be installed only on tablet devices from play store.

How suggested from doc I sett this on my manifest

<supports-screens
        android:largeScreens="true"
        android:normalScreens="false"
        android:requiresSmallestWidthDp="600"
        android:smallScreens="false"
        android:xlargeScreens="true" />

I studied google doc and other post, for me this should works. It's strage that with this configuration play store doesn't limit any device, the app is available to any device.

Is different from other similar ask because the answer doesn't work.

Can someone help me? thank in advance
