I think a lot depends on how you want your app to look and function. For example, I have a phone/tablet app. On phones, I force the activity to portrait mode and load the various layouts with only one being visible at a time. For tablets, there is a different set of layouts that combine some of the phone layouts onto a single screen. From top to bottom. Tablet-Landscape, tablet-portrait, and phone.
I have in mind the setup for phone and tablet. It look like your ac9ts.
But I have to find for an app to be accepted by google store for phone and tablet.

You upload screenshots for 10-inch tablets, but it seems your APK is not designed for them.
